A Cesarean section (C-section) is surgery to deliver a baby. The baby is taken out through the mother's abdomen. In the United States, almost one in three women has their babies this way. Some C-sections are planned, but many are done when unexpected problems happen during delivery. Reasons for a C-section may include
Health problems in the mother
The mother carrying more than one baby
The size or position of the baby
The baby's health is in danger
Labor is not moving along as it should
The surgery is relatively safe for mother and baby. Still, it is major surgery and carries risks. It also takes longer to recover from a C-section than from vaginal birth. It can raise the risk of having difficulties with future pregnancies. Some women may have problems attempting a vaginal birth later. Still, many women are able to have a vaginal birth after cesarean (VBAC).

Clostridium difficile (C. difficile) is a bacterium that causes diarrhea and more serious intestinal conditions such as colitis. Symptoms include
Watery diarrhea (at least three bowel movements per day for two or more days)
Fever
Loss of appetite
Nausea
Abdominal pain or tenderness
You might get C. difficile disease if you have an illness that requires prolonged use of antibiotics. Increasingly, the disease can also be spread in the hospital. The elderly are also at risk. Treatment is with antibiotics.

In coronary artery disease (CAD), the arteries that supply blood and oxygen to your heart muscle grow hardened and narrowed. You may try treatments such as lifestyle changes, medicines, and angioplasty, a procedure to open the arteries. If these treatments don't help, you may need coronary artery bypass surgery.
The surgery creates a new path for blood to flow to the heart. The surgeon takes a healthy piece of vein from the leg or artery from the chest or wrist. Then the surgeon attaches it to the coronary artery, just above and below the narrowed area or blockage. This allows blood to bypass (get around) the blockage. Sometimes people need more than one bypass.
The results of the surgery usually are excellent. Many people remain symptom-free for many years. You may need surgery again if blockages form in the grafted arteries or veins or in arteries that weren't blocked before. Lifestyle changes and medicines may help prevent arteries from becoming clogged again.
NIH: National Heart, Lung, and Blood Institute
Coronary artery disease (CAD) is the most common type of heart disease. It is the leading cause of death in the United States in both men and women.
CAD happens when the arteries that supply blood to heart muscle become hardened and narrowed. This is due to the buildup of cholesterol and other material, called plaque, on their inner walls. This buildup is called atherosclerosis. As it grows, less blood can flow through the arteries. As a result, the heart muscle can't get the blood or oxygen it needs. This can lead to chest pain (angina) or a heart attack. Most heart attacks happen when a blood clot suddenly cuts off the hearts' blood supply, causing permanent heart damage.
Over time, CAD can also weaken the heart muscle and contribute to heart failure and arrhythmias. Heart failure means the heart can't pump blood well to the rest of the body. Arrhythmias are changes in the normal beating rhythm of the heart.

What is caffeine?
Caffeine is a bitter substance that occurs naturally in more than 60 plants including
Coffee beans
Tea leaves
Kola nuts, which are used to flavor soft drink colas
Cacao pods, which are used to make chocolate products
There is also synthetic (man-made) caffeine, which is added to some medicines, foods, and drinks. For example, some pain relievers, cold medicines, and over-the-counter medicines for alertness contain synthetic caffeine. So do energy drinks and "energy-boosting" gums and snacks.
Most people consume caffeine from drinks. The amounts of caffeine in different drinks can vary a lot, but it is generally
An 8-ounce cup of coffee: 95-200 mg
A 12-ounce can of cola: 35-45 mg
An 8-ounce energy drink: 70-100 mg
An 8-ounce cup of tea: 14-60 mg
What are caffeine's effects on the body?
Caffeine has many effects on your body's metabolism. It
Stimulates your central nervous system, which can make you feel more awake and give you a boost of energy
Is a diuretic, meaning that it helps your body get rid of extra salt and water by urinating more
Increases the release of acid in your stomach, sometimes leading to an upset stomach or heartburn
May interfere with the absorption of calcium in the body
Increases your blood pressure
Within one hour of eating or drinking caffeine, it reaches its peak level in your blood. You may continue to feel the effects of caffeine for four to six hours.
What are the side effects from too much caffeine?
For most people, it is not harmful to consume up to 400mg of caffeine a day. If you do eat or drink too much caffeine, it can cause health problems, such as
Restlessness and shakiness
Insomnia
Headaches
Dizziness
Rapid or abnormal heart rhythm
Dehydration
Anxiety
Dependency, so you need to take more of it to get the same results
Some people are more sensitive to the effects of caffeine than others.
What are energy drinks, and why can they be a problem?
Energy drinks are beverages that have added caffeine. The amount of caffeine in energy drinks can vary widely, and sometimes the labels on the drinks do not give you the actual amount of caffeine in them. Energy drinks may also contain sugars, vitamins, herbs, and supplements.
Companies that make energy drinks claim that the drinks can increase alertness and improve physical and mental performance. This has helped make the drinks popular with American teens and young adults. There's limited data showing that energy drinks might temporarily improve alertness and physical endurance. There is not enough evidence to show that they enhance strength or power. But what we do know is that energy drinks can be dangerous because they have large amounts of caffeine. And since they have lots of sugar, they can contribute to weight gain and worsen diabetes.
Sometimes young people mix their energy drinks with alcohol. It is dangerous to combine alcohol and caffeine. Caffeine can interfere with your ability to recognize how drunk you are, which can lead you to drink more. This also makes you more likely to make bad decisions.
Who should avoid or limit caffeine?
You should check with your health care provider about whether you should limit or avoid caffeine if you
Are pregnant, since caffeine passes through the placenta to your baby
Are breastfeeding, since a small amount of caffeine that you consume is passed along to your baby
Have sleep disorders, including insomnia
Have migraines or other chronic headaches
Have anxiety
Have GERD or ulcers
Have fast or irregular heart rhythms
Have high blood pressure
Take certain medicines or supplements, including stimulants, certain antibiotics, asthma medicines, and heart medicines. Check with your health care provider about whether there might be interactions between caffeine and any medicines and supplements that you take.
Are a child or teen. Neither should have as much caffeine as adults. Children can be especially sensitive to the effects of caffeine.
What is caffeine withdrawal?
If you have been consuming caffeine on a regular basis and then suddenly stop, you may have caffeine withdrawal. Symptoms can include
Headaches
Drowsiness
Irritability
Nausea
Difficulty concentrating
These symptoms usually go away after a couple of days.
You have more calcium in your body than any other mineral. Calcium has many important jobs. The body stores more than 99 percent of its calcium in the bones and teeth to help make and keep them strong. The rest is throughout the body in blood, muscle and the fluid between cells. Your body needs calcium to help muscles and blood vessels contract and expand, to secrete hormones and enzymes and to send messages through the nervous system.
It is important to get plenty of calcium in the foods you eat. Foods rich in calcium include
Dairy products such as milk, cheese, and yogurt
Leafy, green vegetables
Fish with soft bones that you eat, such as canned sardines and salmon
Calcium-enriched foods such as breakfast cereals, fruit juices, soy and rice drinks, and tofu. Check the product labels.
The exact amount of calcium you need depends on your age and other factors. Growing children and teenagers need more calcium than young adults. Older women need plenty of calcium to prevent osteoporosis. People who do not eat enough high-calcium foods should take a calcium supplement.

Corns and calluses are caused by pressure or friction on your skin. They often appear on feet where the bony parts of your feet rub against your shoes. Corns usually appear on the tops or sides of toes while calluses form on the soles of feet. Calluses also can appear on hands or other areas that are rubbed or pressed. Wearing shoes that fit better or using non-medicated pads may help. While bathing, gently rub the corn or callus with a washcloth or pumice stone to help reduce the size. To avoid infection, do not try to shave off the corn or callus. See your doctor, especially if you have diabetes or circulation problems. NIH: National Institute on Aging
Many Americans use medical treatments that are not part of mainstream medicine. When you are using these types of care, it may be called complementary, integrative, or alternative medicine.
Complementary medicine is used together with mainstream medical care. An example is using acupuncture to help with side effects of cancer treatment. When health care providers and facilities offer both types of care, it is called integrative medicine. Alternative medicine is used instead of mainstream medical care.
The claims that non-mainstream practitioners make can sound promising. However, researchers do not know how safe many of these treatments are or how well they work. Studies are underway to determine the safety and usefulness of many of these practices.
To minimize the health risks of a non-mainstream treatment
Discuss it with your doctor. It might have side effects or interact with other medicines.
Find out what the research says about it
Choose practitioners carefully
Tell all of your doctors and practitioners about all of the different types of treatments you use

Campylobacter infection is a common foodborne illness. You get it from eating raw or undercooked poultry. You can also get it from coming in contact with contaminated packages of poultry. Symptoms include
Diarrhea Cramping Abdominal pain Fever Nausea and vomiting Some infected people don't have any symptoms. The illness usually lasts one week. Most people get better without treatment. You should drink extra fluids for as long as the diarrhea lasts. Your doctor will decide whether you need to take antibiotics. To prevent campylobacter infection, cook poultry thoroughly. Use a separate cutting board and utensils for meats and clean them carefully with soap and hot water after use. Centers for Disease Control and Prevention
The leukodystrophies are rare diseases that affect the cells of the brain. Specifically, the diseases affect the myelin sheath, the material that surrounds and protects nerve cells. Damage to this sheath slows down or blocks messages between the brain and the rest of the body. This leads to problems with Movement Speaking Vision Hearing Mental and physical development Most of the leukodystrophies are genetic. They usually appear during infancy or childhood. They can be hard to detect early because children seem healthy at first. However, symptoms gradually get worse over time. There are no cures for any of the leukodystrophies. Medicines, speech therapy and physical therapy might help with symptoms. Researchers are testing bone marrow transplantation as a treatment for some of the leukodystrophies. NIH: National Institute of Neurological Disorders and Stroke
Cancer begins in your cells, which are the building blocks of your body. Normally, your body forms new cells as you need them, replacing old cells that die. Sometimes this process goes wrong. New cells grow even when you don't need them, and old cells don't die when they should. These extra cells can form a mass called a tumor. Tumors can be benign or malignant. Benign tumors aren't cancer while malignant ones are. Cells from malignant tumors can invade nearby tissues. They can also break away and spread to other parts of the body.
Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for where they start. For example, lung cancer starts in the lung, and breast cancer starts in the breast. The spread of cancer from one part of the body to another is called metastasis. Symptoms and treatment depend on the cancer type and how advanced it is. Most treatment plans may include surgery, radiation and/or chemotherapy. Some may involve hormone therapy, immunotherapy or other types of biologic therapy, or stem cell transplantation.
NIH: National Cancer Institute
You have many choices to make about your cancer treatment. One choice you might be thinking about is complementary and alternative medicine (CAM). CAM is the term for medical products and practices that are not part of standard care. Examples of CAM therapies are acupuncture, chiropractic, and herbal medicines.
People with cancer may use CAM to
Help cope with the side effects of cancer treatments
Ease worries of cancer treatment and related stress
Feel that they are doing something more to help their own care
CAM treatments do not work for everyone. Some methods, such as acupuncture, might help with nausea, pain and other side effects of cancer treatment. Talk to your doctor to make sure that all aspects of your cancer care work together.

Tumors during pregnancy are rare, but they can happen. Tumors can be either benign or malignant. Benign tumors aren't cancer. Malignant ones are. The most common cancers in pregnancy are breast cancer, cervical cancer, lymphoma, and melanoma. Cancer itself rarely harms the baby, and some cancer treatments are safe during pregnancy. You and your health care provider will work together to find the best treatment. Your options will depend on how far along the pregnancy is, as well as the type, size, and stage of your cancer.
Another type of tumor that women can get is called a gestational trophoblastic disease (GTD). It happens when a fertilized egg doesn't become a fetus. GTD is not always easy to find. It is usually benign, but some types can be malignant. The most common type of GTD is a molar pregnancy. In its early stages, it may look like a normal pregnancy. You should see your health care provider if you have vaginal bleeding (not menstrual bleeding).
Treatment depends on the type of tumor, whether it has spread to other places, and your overall health.
Normally, your cells grow and die in a controlled way. Cancer cells keep growing without control. Chemotherapy is drug therapy for cancer. It works by killing the cancer cells, stopping them from spreading, or slowing their growth. However, it can also harm healthy cells, which causes side effects.
You may have a lot of side effects, some, or none at all. It depends on the type and amount of chemotherapy you get and how your body reacts. Some common side effects are fatigue, nausea, vomiting, pain, and hair loss. There are ways to prevent or control some side effects. Talk with your health care provider about how to manage them. Healthy cells usually recover after chemotherapy is over, so most side effects gradually go away.
Your treatment plan will depend on the cancer type, the chemotherapy drugs used, the treatment goal, and how your body responds. Chemotherapy may be given alone or with other treatments. You may get treatment every day, every week, or every month. You may have breaks between treatments so that your body has a chance to build new healthy cells. You might take the drugs by mouth, in a shot, as a cream, or intravenously (by IV).
NIH: National Cancer Institute
Immunotherapy is a cancer treatment that helps your immune system fight cancer. It is a type of biological therapy. Biological therapy uses substances that are made from living organisms, or versions of these substances that are made in a lab.
Doctors don't yet use immunotherapy as often as other cancer treatments, such as surgery, chemotherapy, and radiation therapy. But they do use immunotherapy for some types of cancer, and researchers are doing clinical trials to see whether it also works for other types.
When you have cancer, some of your cells begin to multiply without stopping. They spread into the surrounding tissues. One reason that the cancer cells can keep growing and spreading is that they are able to hide from your immune system. Some immunotherapies can "mark" your cancer cells. This makes it easier for your immune system to find and destroy the cells. It is a type of targeted therapy, a treatment that specifically targets cancer cells. Other types of immunotherapies work by boosting your immune system to work better against cancer.
You could get immunotherapy intravenously (by IV), in pills or capsules, or in a cream for your skin. For bladder cancer, they might place it directly into your bladder. You may have treatment every day, week, or month. Some immunotherapies are given in cycles. It depends on your type of cancer, how advanced it is, the type of immunotherapy you get, and how well it is working.
You may have side effects. The most common side effects are skin reactions at the needle site, if you get it by IV. Other side effects may include flu-like symptoms, or rarely, severe reactions.

Cancer begins in the cells, which are the building blocks of your body. Normally, new
cells form as you need them, replacing old cells that die. Sometimes, this process goes
wrong. New cells form when you don't need them, and old cells don't die when they should.
The extra cells can form a tumor. Benign tumors aren't cancer while malignant ones are.
Malignant tumor cells can invade nearby tissues or break away and spread to other parts of
the body. Children can get cancer in the same parts of the body as adults, but there are
differences. Childhood cancers can occur suddenly, without early symptoms, and have a high
rate of cure. The most common children's cancer is leukemia.
Other cancers that affect children include brain tumors, lymphoma, and soft tissue sarcoma.
Symptoms and treatment depend on the cancer type and how advanced it is. Treatment may
include surgery, radiation and/or chemotherapy. NIH: National Cancer Institute
Tumors are abnormal growths in your body. They can be either benign or malignant. Benign tumors aren't cancer. Malignant ones are. Benign tumors grow only in one place. They cannot spread or invade other parts of your body. Even so, they can be dangerous if they press on vital organs, such as your brain.
Tumors are made up of extra cells. Normally, cells grow and divide to form new cells as your body needs them. When cells grow old, they die, and new cells take their place. Sometimes, this process goes wrong. New cells form when your body does not need them, and old cells do not die when they should. These extra cells can divide without stopping and may form tumor.
Treatment often involves surgery. Benign tumors usually don't grow back.

Cancer is common. Half of all men and a third of women will get a diagnosis of cancer in their lifetime. Many people with cancer do survive. Millions of Americans alive today have a history of cancer.
For most people with cancer, living with the disease is the biggest challenge they have ever faced. It can change your routines, roles and relationships. It can cause money and work problems. The treatment can change the way you feel and look. Learning more about ways you can help yourself may ease some of your concerns. Support from others is important.
All cancer survivors should have follow-up care. Knowing what to expect after cancer treatment can help you and your family make plans, lifestyle changes, and important decisions.

Candida is the scientific name for yeast. It is a fungus that lives almost everywhere, including in your body. Usually, your immune system keeps yeast under control. If you are sick or taking antibiotics, it can multiply and cause an infection.
Yeast infections affect different parts of the body in different ways:
Thrush is a yeast infection that causes white patches in your mouth
Candida esophagitis is thrush that spreads to your esophagus, the tube that takes food from your mouth to your stomach. It can make it hard or painful to swallow.
Women can get vaginal yeast infections, causing vaginitis
Yeast infections of the skin cause itching and rashes
Yeast infections in your bloodstream can be life-threatening
Antifungal medicines get rid of yeast infections in most people. If you have a weak immune system, treatment might be more difficult.
Mobility aids help you walk or move from place to place if you are disabled or have an injury. They include
Crutches
Canes
Walkers
Wheelchairs
Motorized scooters
You may need a walker or cane if you are at risk of falling. If you need to keep your body weight off your foot, ankle or knee, you may need crutches. You may need a wheelchair or a scooter if an injury or disease has left you unable to walk.
Choosing these devices takes time and research. You should be fitted for crutches, canes and walkers. If they fit, these devices give you support, but if they don't fit, they can be uncomfortable and unsafe.
Canker sores are small, round sores in your mouth. They can be on the inside of your cheek, under your tongue, or in the back of your throat. They usually have a red edge and a gray center. They can be quite painful. They are not the same as cold sores, which are caused by herpes simplex.
Canker sores aren't contagious. They may happen if you have a viral infection. They may also be triggered by stress, food allergies, lack of vitamins and minerals, hormonal changes or menstrual periods. In some cases the cause is unknown.
In most cases, the sores go away by themselves. Some ointments, creams or rinses may help with the pain. Avoiding hot, spicy food while you have a canker sore also helps.
Marijuana is a green, brown, or gray mix of dried, crumbled parts from the marijuana plant. It can be rolled up and smoked like a cigarette or cigar or smoked in a pipe. Sometimes people mix it in food or inhale it using a vaporizer.
Marijuana can cause problems with memory, learning, and behavior. Smoking it can cause some of the same coughing and breathing problems as smoking cigarettes. Some people get addicted to marijuana after using it for a while. It is more likely to happen if they use marijuana every day, or started using it when they were teenagers.
Some states have approved "medical marijuana" to ease symptoms of various health problems. The U.S. Food and Drug Administration (FDA) has not approved the marijuana plant as a medicine. However, there have been scientific studies of cannabinoids, the chemicals in marijuana. This has led to two FDA-approved medicines. They contain THC, the active ingredient in marijuana. They treat nausea caused by chemotherapy and increase appetite in patients who have severe weight loss from HIV/AIDS. Scientists are doing more research with marijuana and its ingredients to treat many diseases and conditions.

Metabolism is the process your body uses to make energy from the food you eat. Food is made up of proteins, carbohydrates, and fats. Chemicals in your digestive system (enzymes) break the food parts down into sugars and acids, your body's fuel. Your body can use this fuel right away, or it can store the energy in your body tissues. If you have a metabolic disorder, something goes wrong with this process.
Carbohydrate metabolism disorders are a group of metabolic disorders. Normally your enzymes break carbohydrates down into glucose (a type of sugar). If you have one of these disorders, you may not have enough enzymes to break down the carbohydrates. Or the enzymes may not work properly. This causes a harmful amount of sugar to build up in your body. That can lead to health problems, some of which can be serious. Some of the disorders are fatal.
These disorders are inherited. Newborn babies get screened for many of them, using blood tests. If there is a family history of one of these disorders, parents can get genetic testing to see whether they carry the gene. Other genetic tests can tell whether the fetus has the disorder or carries the gene for the disorder.
Treatments may include special diets, supplements, and medicines. Some babies may also need additional treatments, if there are complications. For some disorders, there is no cure, but treatments may help with symptoms.
Carbohydrates are one of the main types of nutrients. They are the most important source of energy for your body. Your digestive system changes carbohydrates into glucose (blood sugar). Your body uses this sugar for energy for your cells, tissues and organs. It stores any extra sugar in your liver and muscles for when it is needed.
Carbohydrates are called simple or complex, depending on their chemical structure. Simple carbohydrates include sugars found naturally in foods such as fruits, vegetables, milk, and milk products. They also include sugars added during food processing and refining. Complex carbohydrates include whole grain breads and cereals, starchy vegetables and legumes. Many of the complex carbohydrates are good sources of fiber.
For a healthy diet, limit the amount of added sugar that you eat and choose whole grains over refined grains.
Carbon monoxide (CO) is a gas that has no odor or color. But it is very dangerous. It can cause sudden illness and death. CO is found in combustion fumes, such as those made by cars and trucks, lanterns, stoves, gas ranges and heating systems. CO from these fumes can build up in places that don't have a good flow of fresh air. You can be poisoned by breathing them in. The most common symptoms of CO poisoning are Headache Dizziness Weakness Nausea Vomiting Chest pain Confusion It is often hard to tell if someone has CO poisoning, because the symptoms may be like those of other illnesses. People who are sleeping or intoxicated can die from CO poisoning before they have symptoms. A CO detector can warn you if you have high levels of CO in your home. Centers for Disease Control and Prevention
Carcinoid tumors are rare, slow-growing cancers. They usually start in the lining of the digestive tract or in the lungs. They grow slowly and don't produce symptoms in the early stages. As a result, the average age of people diagnosed with digestive or lung carcinoids is about 60.
In later stages the tumors sometimes produce hormones that can cause carcinoid syndrome. The syndrome causes flushing of the face and upper chest, diarrhea, and trouble breathing.
Surgery is the main treatment for carcinoid tumors. If they haven't spread to other parts of the body, surgery can cure the cancer.
Cancer begins in your cells, which are the building blocks of your body. Normally, your body forms new cells as you need them, replacing old cells that die. Sometimes this process goes wrong.

The heart has an internal electrical system that controls the rhythm of the heartbeat. Problems can cause abnormal heart rhythms, called arrhythmias. There are many types of arrhythmia. During an arrhythmia, the heart can beat too fast, too slow, or it can stop beating. Sudden cardiac arrest (SCA) occurs when the heart develops an arrhythmia that causes it to stop beating. This is different than a heart attack, where the heart usually continues to beat but blood flow to the heart is blocked.
There are many possible causes of SCA. They include coronary heart disease, physical stress, and some inherited disorders. Sometimes there is no known cause for the SCA.
Without medical attention, the person will die within a few minutes. People are less likely to die if they have early defibrillation. Defibrillation sends an electric shock to restore the heart rhythm to normal. You should give cardiopulmonary resuscitation (CPR) to a person having SCA until defibrillation can be done.
If you have had an SCA, an implantable cardiac defibrillator (ICD) reduces the chance of dying from a second SCA.

If you're like most people, you think that heart disease is a problem for others. But heart disease is the number one killer in the U.S. It is also a major cause of disability. There are many different forms of heart disease. The most common cause of heart disease is narrowing or blockage of the coronary arteries, the blood vessels that supply blood to the heart itself. This is called coronary artery disease and
happens slowly over time. It's the major reason people have heart attacks.
Other kinds of heart problems may happen to the valves in the heart, or the heart may not pump well and cause heart failure. Some people are born with heart disease.
You can help reduce your risk of heart disease by taking steps to control factors that put you at greater risk:
Control your blood pressure
Lower your cholesterol
Don't smoke
Get enough exercise
NIH: National Heart, Lung, and Blood Institute
Heart failure is a condition in which the heart can't pump enough blood to meet the body's needs. Heart failure does not mean that your heart has stopped or is about to stop working. It means that your heart is not able to pump blood the way it should. It can affect one or both sides of the heart.
The weakening of the heart's pumping ability causes
Blood and fluid to back up into the lungs
The buildup of fluid in the feet, ankles and legs - called edema
Tiredness and shortness of breath
Common causes of heart failure are coronary artery disease, high blood pressure and diabetes. It is more common in people who are 65 years old or older, African Americans, people who are overweight, and people who have had a heart attack. Men have a higher rate of heart failure than women.
Your doctor will diagnose heart failure by doing a physical exam and heart tests. Treatment includes treating the underlying cause of your heart failure, medicines, and heart transplantation if other treatments fail.
NIH: National Heart, Lung, and Blood Institute
Cardiac rehabilitation (rehab) is a medically supervised program to help people who have
A heart attack
Angioplasty or coronary artery bypass grafting for coronary heart disease
A heart valve repair or replacement
A heart transplant or a lung transplant
Angina
Heart failure
The goal is to help you return to an active life, and to reduce the risk of further heart problems. A team of specialists will create a plan for you that includes exercise training, education on heart healthy living, and counseling to reduce stress. You will learn how to reduce your risk factors, such as high blood pressure, high blood cholesterol, depression, and diabetes. Being overweight or obese, smoking, and not exercising are other risk factors.
NIH: National Heart, Lung, and Blood Institute
Heart surgery can correct problems with the heart if other treatments haven't worked or can't be used. The most common type of heart surgery for adults is coronary artery bypass grafting (CABG). During CABG, a healthy artery or vein from the body is connected, or grafted, to a blocked coronary (heart) artery.
Doctors also use heart surgery to
Repair or replace heart valves, which control blood flow through the heart
Repair abnormal or damaged structures in the heart
Implant medical devices that help control the heartbeat or support heart function and blood flow
Replace a damaged heart with a healthy heart from a donor
Treat heart failure and coronary heart disease
Control abnormal heart rhythms
Heart surgery has risks, even though its results often are excellent. Risks include bleeding, infection, irregular heartbeats, and stroke. The risk is higher if you are older or a woman. The risk is also higher if you have other diseases or conditions, such as diabetes, kidney disease, lung disease, or peripheral arterial disease.
NIH: National Heart, Lung, and Blood Institute
Heart diseases are the number one killer in the U.S. They are also a major cause of disability. If you do have a heart disease, it is important to find it early, when it is easier to treat. Blood tests and heart health tests can help find heart diseases or identify problems that can lead to heart diseases. There are several different types of heart health tests. Your doctor will decide which test or tests you need, based on your symptoms (if any), risk factors, and medical history.
Cardiac Catheterization
Cardiac catheterization is a medical procedure used to diagnose and treat some heart conditions. For the procedure, your doctor puts a catheter (a long, thin, flexible tube) into a blood vessel in your arm, groin, or neck, and threads it to your heart. The doctor can use the catheter to
Do a coronary angiography. This involves putting a special type of dye in the catheter, so the dye can flow through your bloodstream to your heart. Then your doctor takes x-rays of your heart. The dye allows your doctor to see your coronary arteries on the x-ray, and to check for coronary artery disease (plaque buildup in the arteries).
Take samples of blood and heart muscle
Do procedures such as minor heart surgery or angioplasty, if your doctor finds that you need it
Cardiac CT Scan
A cardiac CT (computed tomography) scan is a painless imaging test that uses x-rays to take detailed pictures of your heart and its blood vessels. Computers can combine these pictures to create a three-dimensional (3D) model of the whole heart. This test can help doctors detect or evaluate
Coronary artery disease
Calcium buildup in the coronary arteries
Problems with the aorta
Problems with heart function and valves
Pericardial diseases
Before you have the test, you get an injection of contrast dye. The dye highlights your heart and blood vessels in the pictures. The CT scanner is a large, tunnel-like machine. You lie still on a table which slides you into the scanner, and the scanner takes the pictures for about 15 minutes.
Cardiac MRI
Cardiac MRI (magnetic resonance imaging) is a painless imaging test that uses radio waves, magnets, and a computer to create detailed pictures of your heart. It can help your doctor figure out whether you have heart disease, and if so, how severe it is. A cardiac MRI can also help your doctor decide the best way to treat heart problems such as
Coronary artery disease
Heart valve problems
Pericarditis
Cardiac tumors
Damage from a heart attack
The MRI is a large, tunnel-like machine. You lie still on a table which slides you into the MRI machine. The machine makes loud noises as it takes pictures of your heart. It usually takes about 30-90 minutes. Sometimes before the test, you might get an injection of contrast dye. The dye highlights your heart and blood vessels in the pictures.
Chest X-Ray
A chest x-ray creates pictures of the organs and structures inside your chest, such as your heart, lungs, and blood vessels. It can reveal signs of heart failure, as well as lung disorders and other causes of symptoms not related to heart disease.
Coronary Angiography
Coronary angiography (angiogram) is a procedure that uses contrast dye and x-ray pictures to look at the insides of your arteries. It can show whether plaque is blocking your arteries and how severe the blockage is. Doctors use this procedure to diagnose heart diseases after chest pain, sudden cardiac arrest, or abnormal results from other heart tests such as an EKG or a stress test.
You usually have a cardiac catheterization to get the dye into your coronary arteries. Then you have special x-rays while the dye is flowing through your coronary arteries. The dye lets your doctor study the flow of blood through your heart and blood vessels.
Echocardiography
Echocardiography, or echo, is a painless test that uses sound waves to create moving pictures of your heart. The pictures show the size and shape of your heart. They also show how well your heart's chambers and valves are working. Doctors use an echo to diagnose many different heart problems, and to check how severe they are.
For the test, a technician applies gel to your chest. The gel helps sound waves reach your heart. The technician moves a transducer (wand-like device) around on your chest. The transducer connects to a computer. It transmits ultrasound waves into your chest, and the waves bounce (echo) back. The computer converts the echoes into pictures of your heart.
Electrocardiogram (EKG), (ECG)
An electrocardiogram, also called an ECG or EKG, is a painless test that detects and records your heart's electrical activity. It shows how fast your heart is beating and whether its rhythm is steady or irregular.
An EKG may be part of a routine exam to screen for heart disease. Or you may get it to detect and study heart problems such as heart attacks, arrhythmia, and heart failure.
For the test, you lie still on a table and a nurse or technician attaches electrodes (patches that have sensors) to the skin on your chest, arms, and legs. Wires connect the electrodes to a machine that records your heart's electrical activity.
Stress Testing
Stress testing looks at how your heart works during physical stress. It can help to diagnose coronary artery disease, and to check how severe it is. It can also check for other problems, including heart valve disease and heart failure.
For the test, you exercise (or are given medicine if you are unable to exercise) to make your heart work hard and beat fast. While this is happening, you get an EKG and blood pressure monitoring. Sometimes you may also have an echocardiogram, or other imaging tests such as a nuclear scan. For the nuclear scan, you get an injection of a tracer (a radioactive substance), which travels to your heart. Special cameras detect the energy from the tracer to make pictures of your heart. You have pictures taken after you exercise, and then after you rest.

Cardiomyopathy is the name for diseases of the heart muscle. These diseases enlarge your heart muscle or make it thicker and more rigid than normal. In rare cases, scar tissue replaces the muscle tissue.
Some people live long, healthy lives with cardiomyopathy. Some people don't even realize they have it. In others, however, it can make the heart less able to pump blood through the body. This can cause serious complications, including
Heart failure
Abnormal heart rhythms
Heart valve problems
Sudden cardiac arrest
Heart attacks, high blood pressure, infections, and other diseases can all cause cardiomyopathy. Some types of cardiomyopathy run in families. In many people, however, the cause is unknown. Treatment might involve medicines, surgery, other medical procedures, and lifestyle changes.

When someone's blood flow or breathing stops, seconds count. Permanent brain damage or death can happen quickly. If you know how to perform cardiopulmonary resuscitation (CPR), you could save a life. CPR is an emergency procedure for a person whose heart has stopped or is no longer breathing. CPR can maintain circulation and breathing until emergency medical help arrives.
Even if you haven't had training, you can do "hands-only" CPR for a teen or adult whose heart has stopped beating ("hands-only" CPR isn't recommended for children). "Hands-only" CPR uses chest compressions to keep blood circulating until emergency help arrives. If you've had training, you can use chest compressions, clear the airway, and do rescue breathing. Rescue breathing helps get oxygen to the lungs for a person who has stopped breathing. To keep your skills up, you should repeat the training every two years.
The esophagus is the tube that carries food, liquids and saliva from your mouth to the stomach. You may not be aware of your esophagus until you swallow something too large, too hot or too cold. You may also become aware of it when something is wrong. The most common problem with the esophagus is gastroesophageal reflux disease (GERD). It happens when a band of muscle at the end of your esophagus does not close properly. This allows stomach contents to leak back, or reflux, into the esophagus and irritate it. Over time, GERD can cause damage to the esophagus. Other problems include heartburn and cancer. Treatment depends on the problem. Some get better with over-the-counter medicines or changes in diet. Others may need prescription medicines or surgery.
If you're like most people, you think that heart disease is a problem for others. But heart disease is the number one killer in the U.S. It is also a major cause of disability. There are many different forms of heart disease. The most common cause of heart disease is narrowing or blockage of the coronary arteries, the blood vessels that supply blood to the heart itself. This is called coronary artery disease and
happens slowly over time. It's the major reason people have heart attacks.
Other kinds of heart problems may happen to the valves in the heart, or the heart may not pump well and cause heart failure. Some people are born with heart disease.
You can help reduce your risk of heart disease by taking steps to control factors that put you at greater risk:
Control your blood pressure
Lower your cholesterol
Don't smoke
Get enough exercise

Every day, around the clock, people who work in the health care industry provide care for millions of people, from newborns to the very ill. In fact, the health care industry is one of largest providers of jobs in the United States. Many health jobs are in hospitals. Others are in nursing homes, doctors' offices, dentists' offices, outpatient clinics and laboratories.
To work in a health occupation, you often must have special training. Some, like doctors, must have more than 4 years of college.

Caregivers provide help to another person in need. The person receiving care may be an adult - often a parent or a spouse - or a child with special medical needs. Some caregivers are family members. Others are paid. They do many things:
Shop for food and cook
Clean the house
Pay bills
Give medicine
Help the person go to the toilet, bathe and dress
Help the person eat
Provide company and emotional support
Caregiving is hard, and caregivers of chronically ill people often feel stress. They are "on call" 24 hours a day, 7 days a week. If you're caring for someone with mental problems like Alzheimer's disease it can be especially difficult. Support groups can help.
Dept. of Health and Human Services Office on Women's Health
Caring for someone who has Alzheimer's disease (AD) can be stressful and overwhelming. It's important to take care of yourself. Ask for and accept help. Talk to the doctor. Find out what treatments might help control symptoms or address behavior problems. Find a support group. Others who have "been there" may be able to help and will understand. If there are times of day that the person is less confused or more cooperative, take advantage of that in daily routines. Consider using adult day care or respite services. These offer a break with the peace of mind that the patient is being taken care of. Begin to plan for the future. This may include Getting financial and legal documents in order Looking into assisted living or nursing homes Finding out what your health insurance and Medicare will cover NIH: National Institute on Aging
Your carotid arteries are two large blood vessels in your neck. They supply your brain with blood. If you have carotid artery disease, the arteries become narrow, usually because of atherosclerosis. This is the buildup of cholesterol and other material in an artery. If a blood clot sticks in the narrowed arteries, blood can't reach your brain. This is one of the causes of stroke.
Carotid artery disease often does not cause symptoms, but there are tests that can tell your doctor if you have it. If the arteries are very narrow, you may need an operation called an endarterectomy to remove the plaque. For less severe narrowing, a medicine to prevent blood clots can reduce your risk of stroke. Another option for people who can't have surgery is carotid angioplasty. This involves placing balloons and/or stents into the artery to open it and hold it open.

You're working at your desk, trying to ignore the tingling or numbness you've had for some time in your hand and wrist. Suddenly, a sharp, piercing pain shoots through the wrist and up your arm. Just a passing cramp? It could be carpal tunnel syndrome.
The carpal tunnel is a narrow passageway of ligament and bones at the base of your hand. It contains nerve and tendons. Sometimes, thickening from irritated tendons or other swelling narrows the tunnel and causes the nerve to be compressed. Symptoms usually start gradually. As they worsen, grasping objects can become difficult.
Often, the cause is having a smaller carpal tunnel than other people do. Other causes include performing assembly line work, wrist injury, or swelling due to certain diseases, such as rheumatoid arthritis. Women are three times more likely to have carpal tunnel syndrome than men.
Early diagnosis and treatment are important to prevent permanent nerve damage. Your doctor diagnoses carpal tunnel syndrome with a physical exam and special nerve tests. Treatment includes resting your hand, splints, pain and anti-inflammatory medicines, and sometimes surgery.

Motion sickness is a common problem in people traveling by car, train, airplanes, and
especially boats. Anyone can get it, but it is more common in children, pregnant women, and people taking certain medicines. Motion sickness can start suddenly, with a queasy feeling and cold sweats. It can then lead to dizziness and nausea and vomiting.
Your brain senses movement by getting signals from your inner ears, eyes, muscles, and joints. When it gets signals that do not match, you can get motion sickness. For example, if you are reading on your phone while riding a bus, your eyes are focused on something that is not moving, but your inner ear senses motion.
Where you sit can make a difference. The front seat of a car, forward cars of a train, upper deck on a boat or wing seats in a plane may give you a smoother ride. Looking out into the distance - instead of trying to read or look at something in the vehicle - can also help.

Cartilage is the tough but flexible tissue that covers the ends of your bones at a joint. It also gives shape and support to other parts of your body, such as your ears, nose and windpipe. Healthy cartilage helps you move by allowing your bones to glide over each other. It also protects bones by preventing them from rubbing against each other.
Injured, inflamed, or damaged cartilage can cause symptoms such as pain and limited movement. It can also lead to joint damage and deformity. Causes of cartilage problems include
Tears and injuries, such as sports injuries
Genetic factors
Other disorders, such as some types of arthritis
Osteoarthritis results from breakdown of cartilage.

Wild animals usually avoid people. They might attack, however, if they feel threatened, are sick, or are protecting their young or territory. Attacks by pets are more common. Animal bites rarely are life-threatening, but if they become infected, you can develop serious medical problems.
To prevent animal bites and complications from bites
Never pet, handle, or feed unknown animals
Leave snakes alone
Watch your children closely around animals
Vaccinate your cats, ferrets, and dogs against rabies
Spay or neuter your dog to make it less aggressive
Get a tetanus booster if you have not had one recently
Wear boots and long pants when you are in areas with venomous snakes
If an animal bites you, clean the wound with soap and water as soon as possible. Get medical attention if necessary.

Computed tomography (CT) is a type of imaging. It uses special x-ray equipment to make cross-sectional pictures of your body.
Doctors use CT scans to look for
Broken bones
Cancers
Blood clots
Signs of heart disease
Internal bleeding
During a CT scan, you lie still on a table. The table slowly passes through the center of a large X-ray machine. The test is painless. During some tests you receive a contrast dye, which makes parts of your body show up better in the image.

Cat scratch disease (CSD) is an illness caused by the bacterium Bartonella henselae. Almost half of all cats carry the infection at some point. The infection does not make cats sick. However, the scratch or bite of an infected cat can cause symptoms in people, including
Swollen lymph nodes, especially around the head, neck, and upper limbs
Fever
Headache
Fatigue
Poor appetite
For people with weak immune systems, CSD may cause more serious problems. The best way to avoid CSD is to avoid rough play with cats that could lead to scratches or bites. If you do get a scratch or bite, wash it well with soap and water. If the bite or scratch gets infected or if you have symptoms of CSD, call your doctor.

A cataract is a clouding of the lens in your eye. It affects your vision. Cataracts are very common in older people. By age 80, more than half of all Americans either have a cataract or have had cataract surgery.
A cataract can occur in either or both eyes. It cannot spread from one eye to the other. Common symptoms are
Blurry vision
Colors that seem faded
Glare - headlights, lamps or sunlight may seem too bright. You may also see a halo around lights.
Not being able to see well at night
Double vision
Frequent prescription changes in your eye wear
Cataracts usually develop slowly. New glasses, brighter lighting, anti-glare sunglasses or magnifying lenses can help at first. Surgery is also an option. It involves removing the cloudy lens and replacing it with an artificial lens. Wearing sunglasses and a hat with a brim to block ultraviolet sunlight may help to delay cataracts.

Complex regional pain syndrome (CRPS) is a chronic pain condition. It causes intense pain, usually in the arms, hands, legs, or feet. It may happen after an injury, either to a nerve or to tissue in the affected area. Rest and time may only make it worse.
Symptoms in the affected area are
Dramatic changes in skin temperature, color, or texture
Intense burning pain
Extreme skin sensitivity
Swelling and stiffness in affected joints
Decreased ability to move the affected body part
The cause of CRPS is unknown. There is no specific diagnostic test. Your doctor will diagnose CRPS based on your signs and symptoms.
There is no cure. It can get worse over time, and may spread to other parts of the body. Occasionally it goes away, either temporarily or for good. Treatment focuses on relieving the pain, and can include medicines, physical therapy, and nerve blocks.

You call it a cavity. Your dentist calls it tooth decay or dental caries. They're all names for a hole in your tooth. The cause of tooth decay is plaque, a sticky substance in your mouth made up mostly of germs. Tooth decay starts in the outer layer, called the enamel. Without a filling, the decay can get deep into the tooth and its nerves and cause a toothache or abscess. To help prevent cavities Brush your teeth every day with a fluoride toothpaste Clean between your teeth every day with floss or another type of between-the-teeth cleaner Snack smart - limit sugary snacks See your dentist or oral health professional regularly
Celiac disease is an immune disease in which people can't eat gluten because it will damage their small intestine. If you have celiac disease and eat foods with gluten, your immune system responds by damaging the small intestine. Gluten is a protein found in wheat, rye, and barley. It is found mainly in foods but may also be in other products like medicines, vitamins and supplements, lip balm, and even the glue on stamps and envelopes.
Celiac disease affects each person differently. Symptoms may occur in the digestive system, or in other parts of the body. One person might have diarrhea and abdominal pain, while another person may be irritable or depressed. Irritability is one of the most common symptoms in children. Some people have no symptoms.
Celiac disease is genetic. Blood tests can help your doctor diagnose the disease. Your doctor may also need to examine a small piece of tissue from your small intestine. Treatment is a diet free of gluten.

Some people worry about EMF exposure and cancer. Some studies have found a link between EMF exposure and a higher risk of childhood leukemia, but other studies have not. Other studies have not found proof that EMF exposure causes other childhood cancers. Studies in adults did not prove that EMF exposure causes cancer.
Some people worry that wireless and cellular phones cause cancer or other health problems. The phones do give off radio-frequency energy (RF), a form of electromagnetic radiation. So far, scientific evidence has not found a link between cell phone use and health problems in humans. However, scientists need to do more research on this before they can say for sure.

Cellulitis is an infection of the skin and deep underlying tissues. Group A strep (streptococcal) bacteria are the most common cause. The bacteria enter your body when you get an injury such as a bruise, burn, surgical cut, or wound.
Symptoms include
Fever and chills
Swollen glands or lymph nodes
A rash with painful, red, tender skin. The skin may blister and scab over.
Your health care provider may take a sample or culture from your skin or do a blood test to identify the bacteria causing infection. Treatment is with antibiotics. They may be oral in mild cases, or intravenous (by IV) for more severe cases.

Most brain malformations begin long before a baby is born. Something damages the developing nervous system or causes it to develop abnormally. Sometimes it's a genetic problem. In other cases, exposure to certain medicines, infections, or radiation during pregnancy interferes with brain development. Parts of the brain may be missing, abnormally small or large, or not fully developed.
Treatment depends upon the problem. In many cases, treatment only helps with symptoms. It may include antiseizure medicines, shunts to drain fluid from the brain, and physical therapy.
There are head malformations that do not involve the brain. Craniofacial disorders are the result of abnormal growth of soft tissue and bones in the face and head. It's common for new babies to have slightly uneven heads, but parents should watch the shape of their baby's head for possible problems.

When you play the piano or hit a tennis ball you are activating the cerebellum. The cerebellum is the area of the brain that controls coordination and balance. Problems with the cerebellum include
Cancer
Genetic disorders
Ataxias - failure of muscle control in the arms and legs that result in movement disorders
Degeneration - disorders caused by brain cells decreasing in size or wasting away
Treatment of cerebellar disorders depends on the cause. In some cases, there is no cure but treatment may help with symptoms.

A brain aneurysm is an abnormal bulge or "ballooning" in the wall of an artery in the brain. They are sometimes called berry aneurysms because they are often the size of a small berry. Most brain aneurysms produce no symptoms until they become large, begin to leak blood, or burst.
If a brain aneurysm presses on nerves in your brain, it can cause signs and symptoms. These can include
A droopy eyelid
Double vision or other changes in vision
Pain above or behind the eye
A dilated pupil
Numbness or weakness on one side of the face or body
Treatment depends on the size and location of the aneurysm, whether it is infected, and whether it has burst. If a brain aneurysm bursts, symptoms can include a sudden, severe headache, nausea and vomiting, stiff neck, loss of consciousness, and signs of a stroke. Any of these symptoms requires immediate medical attention.
NIH: National Heart, Lung, and Blood Institute
A stroke is a medical emergency. There are two types - ischemic and hemorrhagic. Hemorrhagic stroke is the less common type. It happens when a blood vessel breaks and bleeds into the brain. Within minutes, brain cells begin to die. Causes include a bleeding aneurysm, an arteriovenous malformation (AVM), or an artery wall that breaks open.
Symptoms of stroke are
Sudden numbness or weakness of the face, arm or leg (especially on one side of the body)
Sudden confusion, trouble speaking or understanding speech
Sudden trouble seeing in one or both eyes
Sudden trouble walking, dizziness, loss of balance or coordination
Sudden severe headache with no known cause
It is important to treat strokes as quickly as possible. With a hemorrhagic stroke, the first steps are to find the cause of bleeding in the brain and then control it. Surgery may be needed. Post-stroke rehabilitation can help people overcome disabilities caused by stroke damage.

Cerebral palsy is a group of disorders that affect a person's ability to move and to maintain balance and posture. The disorders appear in the first few years of life. Usually they do not get worse over time. People with cerebral palsy may have difficulty walking. They may also have trouble with tasks such as writing or using scissors. Some have other medical conditions, including seizure disorders or mental impairment.
Cerebral palsy happens when the areas of the brain that control movement and posture do not develop correctly or get damaged. Early signs of cerebral palsy usually appear before 3 years of age. Babies with cerebral palsy are often slow to roll over, sit, crawl, smile, or walk. Some babies are born with cerebral palsy; others get it after they are born.
There is no cure for cerebral palsy, but treatment can improve the lives of those who have it. Treatment includes medicines, braces, and physical, occupational and speech therapy.
NIH: National Institute of Neurological Disorders and Stroke
A stroke is a medical emergency. Strokes happen when blood flow to your brain stops. Within minutes, brain cells begin to die. There are two kinds of stroke. The more common kind, called ischemic stroke, is caused by a blood clot that blocks or plugs a blood vessel in the brain. The other kind, called hemorrhagic stroke, is caused by a blood vessel that breaks and bleeds into the brain. "Mini-strokes" or transient ischemic attacks (TIAs), occur when the blood supply to the brain is briefly interrupted.
Symptoms of stroke are
Sudden numbness or weakness of the face, arm or leg (especially on one side of the body)
Sudden confusion, trouble speaking or understanding speech
Sudden trouble seeing in one or both eyes
Sudden trouble walking, dizziness, loss of balance or coordination
Sudden severe headache with no known cause
If you have any of these symptoms, you must get to a hospital quickly to begin treatment. Acute stroke therapies try to stop a stroke while it is happening by quickly dissolving the blood clot or by stopping the bleeding. Post-stroke rehabilitation helps individuals overcome disabilities that result from stroke damage. Drug therapy with blood thinners is the most common treatment for stroke.

The cervix is the lower part of the uterus, the place where a baby grows during pregnancy. Cervical cancer is caused by a virus called HPV. The virus spreads through sexual contact. Most women's bodies are able to fight HPV infection. But sometimes the virus leads to cancer. You're at higher risk if you smoke, have had many children, use birth control pills for a long time, or have HIV infection.
Cervical cancer may not cause any symptoms at first. Later, you may have pelvic pain or bleeding from the vagina. It usually takes several years for normal cells in the cervix to turn into cancer cells. Your health care provider can find abnormal cells by doing a Pap test to examine cells from the cervix. You may also have an HPV test. If your results are abnormal, you may need a biopsy or other tests. By getting regular screenings, you can find and treat any problems before they turn into cancer.
Treatment may include surgery, radiation therapy, chemotherapy, or a combination. The choice of treatment depends on the size of the tumor, whether the cancer has spread and whether you would like to become pregnant someday.
Vaccines can protect against several types of HPV, including some that can cause cancer.
NIH: National Cancer Institute
The cervix is the lower part of the uterus, the place where a baby grows during pregnancy. Cancer screening is looking for cancer before you have any symptoms. Cancer found early may be easier to treat.
Cervical cancer screening is usually part of a woman's health checkup. There are two types of tests: the Pap test and the HPV test. For both, the doctor or nurse collects cells from the surface of the cervix. With the Pap test, the lab checks the sample for cancer cells or abnormal cells that could become cancer later. With the HPV test, the lab checks for HPV infection. HPV is a virus that spreads through sexual contact. It can sometimes lead to cancer. If your screening tests are abnormal, your doctor may do more tests, such as a biopsy.
Cervical cancer screening has risks. The results can sometimes be wrong, and you may have unnecessary follow-up tests. There are also benefits. Screening has been shown to decrease the number of deaths from cervical cancer. You and your doctor should discuss your risk for cervical cancer, the pros and cons of the screening tests, at what age to start being screened, and how often to be screened.
The cervix is the lower part of the uterus, the place where a baby grows during pregnancy. The cervix has a small opening that expands during childbirth. It also allows menstrual blood to leave a woman's body.
Your health care provider may perform a Pap test during your health checkup to look for changes to the cells of the cervix, including cervical cancer. Other problems with the cervix include:
Cervicitis - inflammation of the cervix. This is usually from an infection.
Cervical incompetence - This can happen during pregnancy. The opening of the cervix widens long before the baby is due.
Cervical polyps and cysts - abnormal growths on the cervix
The uterus, or womb, is the place where a baby grows when a woman is pregnant. If you have an ectopic pregnancy, the fertilized egg grows in the wrong place, outside the uterus, usually in the fallopian tubes. The result is usually a miscarriage.
Ectopic pregnancy can be a medical emergency if it ruptures. Signs of ectopic pregnancy include
Abdominal pain
Shoulder pain
Vaginal bleeding
Feeling dizzy or faint
Get medical care right away if you have these signs. Doctors use drugs or surgery to remove the ectopic tissue so it doesn't damage your organs. Many women who have had ectopic pregnancies go on to have healthy pregnancies later.

Any part of your neck - muscles, bones, joints, tendons, ligaments, or nerves - can cause neck problems. Neck pain is very common. Pain may also come from your shoulder, jaw, head, or upper arms.
Muscle strain or tension often causes neck pain. The problem is usually overuse, such as from sitting at a computer for too long. Sometimes you can strain your neck muscles from sleeping in an awkward position or overdoing it during exercise. Falls or accidents, including car accidents, are another common cause of neck pain. Whiplash, a soft tissue injury to the neck, is also called neck sprain or strain.
Treatment depends on the cause, but may include applying ice, taking pain relievers, getting physical therapy or wearing a cervical collar. You rarely need surgery.

A Cesarean section (C-section) is surgery to deliver a baby. The baby is taken out through the mother's abdomen. In the United States, almost one in three women has their babies this way. Some C-sections are planned, but many are done when unexpected problems happen during delivery. Reasons for a C-section may include
Health problems in the mother
The mother carrying more than one baby
The size or position of the baby
The baby's health is in danger
Labor is not moving along as it should
The surgery is relatively safe for mother and baby. Still, it is major surgery and carries risks. It also takes longer to recover from a C-section than from vaginal birth. It can raise the risk of having difficulties with future pregnancies. Some women may have problems attempting a vaginal birth later. Still, many women are able to have a vaginal birth after cesarean (VBAC).

Chronic fatigue syndrome (CFS) is a disorder that causes extreme fatigue. This fatigue is not the kind of tired feeling that goes away after you rest. Instead, it lasts a long time and limits your ability to do ordinary daily activities.
The main symptom of CFS is severe fatigue that lasts for 6 months or more. You also have at least four of these other symptoms:
Feeling unwell for more than 24 hours after physical activity
Muscle pain
Memory problems
Headaches
Pain in multiple joints
Sleep problems
Sore throat
Tender lymph nodes
CFS is hard to diagnose. There are no tests for it, and other illnesses can cause similar symptoms. Your doctor has to rule out other diseases before making a diagnosis of CFS.
No one knows what causes CFS. It is most common in women in their 40s and 50s, but anyone can have it. It can last for years. There is no cure for CFS, so the goal of treatment is to improve symptoms. CFS affects people in different ways. You should work with your doctors to create a treatment program that best meets your own needs. It may include therapies to manage your symptoms, such as medicines to treat pain, sleep disorders, and other problems. It may also include coping techniques, and ways of managing your daily activities.

Chagas disease is caused by a parasite. It is common in Latin America but not in the United States. Infected blood-sucking bugs, sometimes called kissing bugs, spread it. When the bug bites you, usually on your face, it leaves behind infected waste. You can get the infection if you rub it in your eyes or nose, the bite wound or a cut. The disease can also spread through contaminated food, a blood transfusion, a donated organ or from mother to baby during pregnancy.
If you notice symptoms, they might include
Fever
Flu-like symptoms
A rash
A swollen eyelid
These early symptoms usually go away. However, if you don't treat the infection, it stays in your body. Later, it can cause serious intestinal and heart problems.
A physical exam and blood tests can diagnose it. You may also need tests to see whether the disease has affected your intestines and heart.
Medicines can kill the parasite, especially early on. You can also treat related problems. For example, a pacemaker helps with certain heart complications.
There are no vaccines or medicines to prevent Chagas disease. If you travel to areas where it occurs, you are at higher risk if you sleep outdoors or in poor housing conditions. It is important to use insecticides to prevent bites, and practice food safety.

Your eyelids help protect your eyes. When you blink, your eyelids spread moisture over your eyes. Blinking also helps move dirt or other particles off the surface of the eye. You close your eyelids when you see something coming toward your eyes. This can help protect against injuries.
Like most other parts of your body, your eyelids can get infected, inflamed, or even develop cancer. There are also specific eyelid problems, including
Eyelids that turn in or out
Eyelids that droop
Abnormal blinking or twitching
Treatment of eyelid problems depends on the cause.
Menopause is the time in a woman's life when her period stops. It usually occurs naturally, most often after age 45. Menopause happens because the woman's ovaries stop producing the hormones estrogen and progesterone.
A woman has reached menopause when she has not had a period for one year. Changes and symptoms can start several years earlier. They include
A change in periods - shorter or longer, lighter or heavier, with more or less time in between
Hot flashes and/or night sweats
Trouble sleeping
Vaginal dryness
Mood swings
Trouble focusing
Less hair on head, more on face
Some symptoms require treatment. Talk to your doctor about how to best manage menopause. Make sure the doctor knows your medical history and your family medical history. This includes whether you are at risk for heart disease, osteoporosis, or breast cancer.

Charcot-Marie-Tooth disease (CMT) is a group of genetic nerve disorders. It is named after the three doctors who first identified it. In the United States, CMT affects about 1 in 2,500 people.
CMT affects your peripheral nerves. Peripheral nerves carry movement and sensation signals between the brain and spinal cord and the rest of the body. Symptoms usually start around the teen years. Foot problems such as high arches or hammertoes can be early symptoms. As CMT progresses, your lower legs may weaken. Later, your hands may also become weak.
Doctors diagnose CMT by doing a neurologic exam, nerve tests, genetic tests, or a nerve biopsy. There is no cure. The disease can be so mild you don't realize you have it or severe enough to make you weak. Physical therapy, occupational therapy, braces and other devices and sometimes surgery can help.

Muscle cramps are sudden, involuntary contractions or spasms in one or more of your muscles. They often occur after exercise or at night, lasting a few seconds to several minutes. It is a very common muscle problem. Muscle cramps can be caused by nerves that malfunction. Sometimes this malfunction is due to a health problem, such as a spinal cord injury or a pinched nerve in the neck or back. Other causes are Straining or overusing a muscle Dehydration A lack of minerals in your diet or the depletion of minerals in your body Not enough blood getting to your muscles Cramps can be very painful. Stretching or gently massaging the muscle can relieve this pain.
When a hazardous chemical has been released, it may harm people's health. Chemical releases can be unintentional, as in the case of an industrial accident. They could also be planned, as in the case of a terrorist attack with a chemical weapon.
Some hazardous chemicals have been developed by military organizations for use in warfare. Examples are nerve agents such as sarin and VX. Many hazardous chemicals are used in industry - for example, chlorine, ammonia, and benzene. Some can be made from everyday items such as household cleaners.
Although there are no guarantees of safety during a chemical emergency, you can take actions to protect yourself. You should have a disaster plan. Being prepared can help reduce fear, anxiety, and losses. If you do experience a disaster, it is normal to feel stressed. You may need help in finding ways to cope.

Normally, your cells grow and die in a controlled way. Cancer cells keep growing without control. Chemotherapy is drug therapy for cancer. It works by killing the cancer cells, stopping them from spreading, or slowing their growth. However, it can also harm healthy cells, which causes side effects.
You may have a lot of side effects, some, or none at all. It depends on the type and amount of chemotherapy you get and how your body reacts. Some common side effects are fatigue, nausea, vomiting, pain, and hair loss. There are ways to prevent or control some side effects. Talk with your health care provider about how to manage them. Healthy cells usually recover after chemotherapy is over, so most side effects gradually go away.
Your treatment plan will depend on the cancer type, the chemotherapy drugs used, the treatment goal, and how your body responds. Chemotherapy may be given alone or with other treatments. You may get treatment every day, every week, or every month. You may have breaks between treatments so that your body has a chance to build new healthy cells. You might take the drugs by mouth, in a shot, as a cream, or intravenously (by IV).

The chest is the part of the body between your neck and your abdomen. It includes the ribs and breastbone. Inside your chest are several organs, including the heart, lungs, and esophagus. The pleura, a large thin sheet of tissue, lines the inside of the chest cavity.
Chest injuries and disorders include
Heart diseases
Lung diseases and collapsed lung
Pleural disorders
Esophagus disorders
Broken ribs
Thoracic aortic aneurysms
Disorders of the mediastinum, the space between the lungs, breastbone, and spine
Having a pain in your chest can be scary. It does not always mean that you are having a heart attack. There can be many other causes, including
Other heart problems, such as angina
Panic attacks
Digestive problems, such as heartburn or esophagus disorders
Sore muscles
Lung diseases, such as pneumonia, pleurisy, or pulmonary embolism
Costochondritis - an inflammation of joints in your chest
Some of these problems can be serious. Get immediate medical care if you have chest pain that does not go away, crushing pain or pressure in the chest, or chest pain along with nausea, sweating, dizziness or shortness of breath. Treatment depends on the cause of the pain.
Pulmonary rehabilitation (rehab) is a medically supervised program to help people who have chronic breathing problems, including COPD (chronic obstructive pulmonary disease) Sarcoidosis Idiopathic pulmonary fibrosis Cystic fibrosis During pulmonary rehab you may do exercise training and learn breathing techniques. You'll also get tips on conserving your energy and advice on nutrition and coping. These can't cure your lung disease or completely ease your breathing problems. But it can help you function better in your daily life. NIH: National Heart, Lung, and Blood Institute
Many people who chew tobacco or dip snuff think it's safer than smoking. But you don't have to smoke tobacco for it to be dangerous. Chewing or dipping carries risks like Cancer of the mouth Decay of exposed tooth roots Pulling away of the gums from the teeth White patches or red sores in the mouth that can turn to cancer Recent research shows the dangers of smokeless tobacco may go beyond the mouth. It might also play a role in other cancers, heart disease and stroke. Smokeless tobacco contains more nicotine than cigarettes. Nicotine is a highly addictive drug that makes it hard to stop using tobacco once you start. Having a quit date and a quitting plan can help you stop successfully.

Heart failure is a condition in which the heart can't pump enough blood to meet the body's needs. Heart failure does not mean that your heart has stopped or is about to stop working. It means that your heart is not able to pump blood the way it should. It can affect one or both sides of the heart.
The weakening of the heart's pumping ability causes
Blood and fluid to back up into the lungs
The buildup of fluid in the feet, ankles and legs - called edema
Tiredness and shortness of breath
Common causes of heart failure are coronary artery disease, high blood pressure and diabetes. It is more common in people who are 65 years old or older, African Americans, people who are overweight, and people who have had a heart attack. Men have a higher rate of heart failure than women.
Your doctor will diagnose heart failure by doing a physical exam and heart tests. Treatment includes treating the underlying cause of your heart failure, medicines, and heart transplantation if other treatments fail.

Chiari malformations (CMs) are structural defects in the cerebellum. The cerebellum is the part of the brain that controls balance. With CM, brain tissue extends into the spinal canal. It can happen when part of the skull is too small, which pushes the brain tissue down. There are several types of CM. One type often happens in children who have neural tube defects. Some types cause no symptoms and don't need treatment. If you have symptoms, they may include
Neck pain
Balance problems
Numbness or other abnormal feelings in the arms or legs
Dizziness
Vision problems
Difficulty swallowing
Poor hand coordination
Doctors diagnose CM using imaging tests. Medicines may ease some symptoms, such as pain. Surgery is the only treatment available to correct or stop the progression of nerve damage.

Chickenpox is an infection caused by the varicella-zoster virus. Most cases are in children under age 15, but older children and adults can get it. It spreads very easily from one person to another.
The classic symptom of chickenpox is an uncomfortable, itchy rash. The rash turns into fluid-filled blisters and eventually into scabs. It usually shows up on the face, chest, and back and then spreads to the rest of the body. Other symptoms include
Fever
Headache
Tiredness
Loss of appetite
Chickenpox is usually mild and lasts 5 to 10 days. Calamine lotions and oatmeal baths can help with itching. Acetaminophen can treat the fever. Do not use aspirin for chickenpox; that combination can cause Reye syndrome.
Chickenpox can sometimes cause serious problems. Adults, babies, teenagers, pregnant women, and those with weak immune systems tend to get sicker from it. They may need to take antiviral medicines.
Once you catch chickenpox, the virus usually stays in your body. You probably will not get chickenpox again, but the virus can cause shingles in adults. A chickenpox vaccine can help prevent most cases of chickenpox, or make it less severe if you do get it.

Chikungunya is a virus that spread by the same kinds of mosquitoes that spread dengue and Zika virus. Rarely, it can spread from mother to newborn around the time of birth. It may also possibly spread through infected blood. There have been outbreaks of chikungunya virus in Africa, Asia, Europe, the Indian and Pacific Oceans, the Caribbean, and Central and South America.
Most people who are infected will have symptoms, which can be severe. They usually start 3-7 days after being bitten by an infected mosquito. The most common symptoms are fever and joint pain. Other symptoms may include headache, muscle pain, joint swelling, and rash.
Most people feel better within a week. In some cases, however, the joint pain may last for months. People at risk for more severe disease include newborns, older adults, and people with diseases such as high blood pressure, diabetes, or heart disease.
A blood test can show whether you have chikungunya virus. There are no vaccines or medicines to treat it. Drinking lots of fluids, resting, and taking non-aspirin pain relievers might help.
The best way to prevent chikungunya infection is to avoid mosquito bites:
Use insect repellent
Wear clothes that cover your arms, legs, and feet
Stay in places that have air conditioning or that use window and door screens

Frostbite is an injury to the body that is caused by freezing. It most often affects the nose, ears, cheeks, chin, fingers, or toes. Frostbite can permanently damage the body, and severe cases can lead to amputation.
If you have frostbite, the skin in that area may turn white or grayish-yellow. It may feel firm or waxy when you touch it. The area will also feel numb.
If you have symptoms of frostbite, seek medical care. But if immediate medical care isn't available, here are steps to take:
Get into a warm room as soon as possible.
If possible, do not walk on frostbitten feet or toes. Walking increases the damage.
Put the affected area in warm - not hot - water.
You can also warm the affected area using body heat. For example, use your armpit to warm frostbitten fingers.
Don't rub the frostbitten area with snow or massage it at all. This can cause more damage.
Don't use a heating pad, heat lamp, or the heat of a stove, fireplace, or radiator for warming. Since frostbite makes an area numb, you could burn it.

Child abuse is doing something or failing to do something that results in harm to a
child or puts a child at risk of harm. Child abuse can be physical, sexual or emotional. Neglect, or not providing for a child's needs, is also a
form of abuse.
Most abused children suffer greater emotional than physical damage. An abused child may
become depressed. He or she may withdraw, think of suicide or become violent. An older
child may use drugs or alcohol, try to run away or abuse others.
Child abuse is a serious problem. If you suspect a child is being abused or neglected,
call the police or your local child welfare agency.
All kids misbehave some times. And some may have temporary behavior problems due to stress. For example, the birth of a sibling, a divorce, or a death in the family may cause a child to act out. Behavior disorders are more serious. They involve a pattern of hostile, aggressive, or disruptive behaviors for more than 6 months. The behavior is also not appropriate for the child's age.
Warning signs can include
Harming or threatening themselves, other people or pets
Damaging or destroying property
Lying or stealing
Not doing well in school, skipping school
Early smoking, drinking or drug use
Early sexual activity
Frequent tantrums and arguments
Consistent hostility toward authority figures
If you see signs of a problem, ask for help. Poor choices can become habits. Kids who have behavior problems are at higher risk for school failure, mental health problems, and even suicide. Classes or family therapy may help parents learn to set and enforce limits. Talk therapy and behavior therapy for your child can also help.
Children's healthy development depends on safe and positive experiences when they are very young. If you work or go to school, you want to know that your child is in good hands while you are away. You may choose in-home care, where the caregiver comes to your home. Or your child might go to the caregiver's home. Finally, there are child care centers. You need to choose the one that works for your family. It is important to get to know your child's caregivers. They will be a big part of your child's life. The caregiver's training should involve Knowledge of how young children learn and grow Positive, consistent discipline Knowledge of the signs that a child is sick Cleanliness and safety practices to help keep kids from getting sick or hurt Basic first aid
Healthy teeth are important to your child's overall health. From the time your child is born, there are things you can do to promote healthy teeth and prevent cavities. For babies, you should clean teeth with a soft, clean cloth or baby's toothbrush. Avoid putting the baby to bed with a bottle and check teeth regularly for spots or stains.
For all children, you should
Start using a pea-sized amount of fluoride toothpaste when they are two years old. You might start sooner, if a dentist or doctor suggests it.
Provide healthy foods and limit sweet snacks and drinks
Schedule regular dental check-ups
Forming good habits at a young age can help your child have healthy teeth for life.
NIH: National Institute of Dental and Craniofacial Research
As children grow older, they develop in several different ways. Child development includes physical, intellectual, social, and emotional changes.
Children grow and mature at very different rates. It's hard to say what "normal" is. There can be big differences in height, weight, and build among healthy children. Diet, exercise and genes are all factors. Some children begin puberty or are close to it before they are teenagers.
Children start to become more independent from their parents. They may rebel. They also look outward - to their friends, who are usually of the same sex. Peer approval becomes very important. Your child may try new behaviors to be part of "the group." This can also be the time that parents or teachers recognize learning disabilities or behavioral problems in children. These problems can get worse as time goes on, so it is important to get help early.
It's important to recognize and treat mental illnesses in children early on. Once mental illness develops, it becomes a regular part of your child's behavior. This makes it more difficult to treat.
But it's not always easy to know when your child has a serious problem. Everyday stresses can cause changes in your child's behavior. For example, getting a new brother or sister or going to a new school may cause a child to temporarily act out. Warning signs that it might be a more serious problem include
Problems in more than one setting (at school, at home, with peers)
Changes in appetite or sleep
Social withdrawal or fear of things he or she did not used to be not afraid of
Returning to behaviors more common in younger children, such as bedwetting
Signs of being upset, such as sadness or tearfulness
Signs of self-destructive behavior, such as head-banging or suddenly getting hurt often
Repeated thoughts of death
To diagnose mental health problems, the doctor or mental health specialist looks at your child's signs and symptoms, medical history, and family history. Treatments include medicines and talk therapy.
NIH: National Institute of Mental Health
Sexual abuse is one form of child abuse. It includes a wide range of actions between a child and an adult or older child. Often these involve body contact, but not always. Exposing one's genitals to children or pressuring them for sex is sexual abuse. Using a child for pornography is also sexual abuse. Most sexual abusers know the child they abuse. They may be family friends, neighbors or babysitters. About one-third of abusers are related to the child. Most abusers are men. If you think a child may have been abused, it's important to report it.
A healthy diet helps children grow and learn. It also helps prevent obesity and weight-related diseases, such as diabetes. To give your child a nutritious diet
Make half of what is on your child's plate fruits and vegetables
Choose healthy sources of protein, such as lean meat, nuts, and eggs
Serve whole-grain breads and cereals because they are high in fiber. Reduce refined grains.
Broil, grill, or steam foods instead of frying them
Limit fast food and junk food
Offer water or milk instead of sugary fruit drinks and sodas
Learn about your children's nutrient requirements. Some of them, such as the requirements for iron and calcium, change as your child ages.

As parents, we want to keep our children safe from harm. Take steps to keep your children safe:
Install the right child safety seat in your car
Teach children how to cross the street safely
Make sure they wear the right gear and equipment for sports
Install and test smoke alarms
Store medicines, cleaners and other dangerous substances in locked cabinets
Babyproof your home
Don't leave small children unattended

When you are ready to have your baby, you'll go through labor. Labor is the process of giving birth. Signs that you might be going into labor include
Contractions that are regular then start to come closer together
Leaking fluid or bleeding from the vagina
Low, dull backache
Abdominal cramps
Call your health care provider if you have any of these signs, even if it is before your due date. Preterm labor can start before 37 completed weeks of pregnancy.
Labor happens in three stages. The first stage begins with contractions. It continues until your cervix has become thinner and dilated (stretched) to about 4 inches wide. The second stage is the active stage, in which you begin to push downward. Crowning is when your baby's scalp comes into view. Shortly afterward, your baby is born. In the third stage, you deliver the placenta. The placenta is the organ that supplied food and oxygen to your baby during pregnancy.
Mothers and babies are monitored closely during labor. Most women are able to have a baby through normal vaginal delivery. If there are complications, the baby may need to be delivered surgically by a Cesarean section.
NIH: National Institute of Child Health and Human Development
While childbirth usually goes well, complications can happen. They can cause a risk to the mother, baby, or both. Possible complications include
Preterm (premature) labor, when labor starts before 37 completed weeks of pregnancy
Problems with the umbilical cord
Problems with the position of the baby, such as breech, in which the baby is going to come out feet first
Birth injuries
For some of these problems, the baby may need to be delivered surgically by a Cesarean section.
Asthma is a chronic disease that affects your airways. Your airways are tubes that carry air in and out of your lungs. If you have asthma, the inside walls of your airways become sore and swollen.
In the United States, about 20 million people have asthma. Nearly 9 million of them are children. Children have smaller airways than adults, which makes asthma especially serious for them. Children with asthma may experience wheezing, coughing, chest tightness, and trouble breathing, especially early in the morning or at night.
Many things can cause asthma, including
Allergens - mold, pollen, animals
Irritants - cigarette smoke, air pollution
Weather - cold air, changes in weather
Exercise
Infections - flu, common cold
When asthma symptoms become worse than usual, it is called an asthma attack. Asthma is treated with two kinds of medicines: quick-relief medicines to stop asthma symptoms and long-term control medicines to prevent symptoms.
Brain tumors are abnormal growths inside the skull. They are among the most common types of childhood cancers. Some are benign tumors, which aren't cancer. They can still be serious. Malignant tumors are cancerous.
Childhood brain and spinal cord tumors can cause headaches and other symptoms. However, other conditions can also cause the same symptoms. Check with a doctor if your child has any of the following problems:
Morning headache or headache that goes away after vomiting
Frequent nausea and vomiting
Vision, hearing, and speech problems
Loss of balance or trouble walking
Unusual sleepiness
Personality changes
Seizures
Increased head size in infants
The symptoms are not the same in every child.
Doctors use physical and neurological exams, lab tests, and imaging to diagnose brain tumors. Most childhood brain tumors are diagnosed and removed in surgery.
Treatment for children is sometimes different than for an adult. Long-term side effects are an important issue. The options also depend on the type of tumor and where it is. Removal of the tumor is often possible. If not, radiation, chemotherapy, or both may be used.
NIH: National Cancer Institute
Cancer begins in the cells, which are the building blocks of your body. Normally, new
cells form as you need them, replacing old cells that die. Sometimes, this process goes
wrong. New cells form when you don't need them, and old cells don't die when they should.
The extra cells can form a tumor. Benign tumors aren't cancer while malignant ones are.
Malignant tumor cells can invade nearby tissues or break away and spread to other parts of
the body. Children can get cancer in the same parts of the body as adults, but there are
differences. Childhood cancers can occur suddenly, without early symptoms, and have a high
rate of cure. The most common children's cancer is leukemia.
Other cancers that affect children include brain tumors, lymphoma, and soft tissue sarcoma.
Symptoms and treatment depend on the cancer type and how advanced it is. Treatment may
include surgery, radiation and/or chemotherapy. NIH: National Cancer Institute
Today, children in the United States routinely get vaccines that protect them from more than a dozen diseases such as measles, polio, tetanus, diphtheria, and pertussis (whooping cough). Most of these diseases are now at their lowest levels in history, thanks to years of immunization. Children must get at least some vaccines before they may attend school.
Vaccines help make you immune to serious diseases without getting sick first. Without a vaccine, you must actually get a disease in order to become immune to the germ that causes it. Vaccines work best when they are given at certain ages. For example, children don't receive measles vaccine until they are at least one year old. If it is given earlier it might not work as well. The Centers for Disease Control and Prevention publishes a schedule for childhood vaccines.
Although some of the vaccines you receive as a child provide protection for many years, adults need immunizations too.
Centers for Disease Control and Prevention
Leukemia is cancer of the white blood cells. It is the most common type of childhood cancer. Your blood cells form in your bone marrow. White blood cells help your body fight infection. In leukemia, the bone marrow produces abnormal white blood cells. These cells crowd out the healthy blood cells, making it hard for blood to do its work.
Leukemia can develop quickly or slowly. Acute leukemia is a fast growing type while chronic leukemia grows slowly. Children with leukemia usually have one of the acute types.
Symptoms include
Infections
Fever
Loss of appetite
Tiredness
Easy bruising or bleeding
Swollen lymph nodes
Night sweats
Shortness of breath
Pain in the bones or joints
Risk factors for childhood leukemia include having a brother or sister with leukemia, having certain genetic disorders and having had radiation or chemotherapy. Treatment often cures childhood leukemia. Treatment options include chemotherapy, other drug therapy and radiation. In some cases bone marrow and blood stem cell transplantation might help.

Obesity means having too much body fat. It is different from being overweight, which means weighing too much. Both terms mean that a person's weight is greater than what's considered healthy for his or her height. Children grow at different rates, so it isn't always easy to know when a child is obese or overweight. Ask your health care provider to check whether your child's weight and height are in a healthy range.
If a weight-loss program is necessary, involve the whole family in healthy habits so your child doesn't feel singled out. Encourage healthy eating by
Serving more fruits and vegetables
Buying fewer soft drinks and high-fat, high-calorie snack foods
Making sure your child eats breakfast every day
Eating fast food less often
Not using food as a reward
Physical activity is also very important. Kids need about 60 minutes each day. It does not have to happen all at once. Several short periods of activity during the day are just as good.
NIH: National Institute of Diabetes and Digestive and Kidney Diseases
Until recently, the common type of diabetes in children and teens was type 1. It was called juvenile diabetes. With Type 1 diabetes, the pancreas does not make insulin. Insulin is a hormone that helps glucose,or sugar, get into your cells to give them energy. Without insulin, too much sugar stays in the blood.
But now younger people are also getting type 2 diabetes. Type 2 diabetes used to be called adult-onset diabetes. But now it is becoming more common in children and teens, due to more obesity. With Type 2 diabetes, the body does not make or use insulin well.
Children have a higher risk of type 2 diabetes if they are obese, have a family history of diabetes, or are not active, and do not eat well. To lower the risk of type 2 diabetes in children
Have them maintain a healthy weight
Be sure they are physically active
Have them eat smaller portions of healthy foods
Limit time with the TV, computer, and video
Children and teens with type 1 diabetes may need to take insulin. Type 2 diabetes may be controlled with diet and exercise. If not, patients will need to take oral diabetes medicines or insulin. A blood test called the A1C can check on how you are managing your diabetes.
When it comes to taking medicines, kids aren't just small adults. For prescription medicines, there is a "Pediatric" section of the label. It says whether the medication has been studied for its effects on children. It also tells you what ages have been studied. Aside from drugs for fever or pain, most over-the-counter products haven't actually been studied in children for effectiveness, safety, or dosing. When you give medicine to your child, be sure you're giving the right medicine and the right amount. Read and follow the label directions. Use the correct dosing device. If the label says two teaspoons and you're using a dosing cup with ounces only, don't guess. Get the proper measuring device. Don't substitute another item, such as a kitchen spoon. Talk to your doctor, pharmacist, or other health care provider before giving two medicines at the same time. That way, you can avoid a possible overdose or an unwanted interaction. Follow age and weight limit recommendations. If the label says don't give to children under a certain age or weight, don't do it. Food and Drug Administration
Your child's health includes physical, mental and social well-being. Most parents know the basics of keeping children healthy, like offering them healthy foods, making sure they get enough sleep and exercise and insuring their safety.
It is also important for children to get regular checkups with their health care provider. These visits are a chance to check your child's development. They are also a good time to catch or prevent problems.
Other than checkups, school-age children should be seen for
Significant weight gain or loss
Sleep problems or change in behavior
Fever higher than 102
Rashes or skin infections
Frequent sore throats
Breathing problems

Chiropractic is a health care profession. Chiropractors perform adjustments (manipulations) to the spine or other parts of the body. The goal is to correct alignment problems, ease pain, and support the body's natural ability to heal itself. They may also use other treatments including
Heat and ice
Electrical stimulation
Relaxation techniques
Rehabilitative and general exercise
Counseling about diet, weight loss, and other lifestyle factors
Dietary supplements
Many people visit chiropractors for treatment of low back pain, neck pain, and headaches.

What is chlamydia?
Chlamydia is a common sexually transmitted disease. It is caused by bacteria called Chlamydia trachomatis. It can infect both men and women. Women can get chlamydia in the cervix, rectum, or throat. Men can get chlamydia in the urethra (inside the penis), rectum, or throat.
How do you get chlamydia?
You can get chlamydia during oral, vaginal, or anal sex with someone who has the infection. A woman can also pass chlamydia to her baby during childbirth.
If you've had chlamydia and were treated in the past, you can get re-infected if you have unprotected sex with someone who has it.
Who is at risk of getting chlamydia?
Chlamydia is more common in young people, especially young women. You are more likely to get it if you don't consistently use a condom, or if you have multiple partners.
What are the symptoms of chlamydia?
Chlamydia doesn't usually cause any symptoms. So you may not realize that you have it. People with chlamydia who have no symptoms can still pass the disease to others. If you do have symptoms, they may not appear until several weeks after you have sex with an infected partner.
Symptoms in women include
Abnormal vaginal discharge, which may have a strong smell
A burning sensation when urinating
Pain during intercourse
If the infection spreads, you might get lower abdominal pain, pain during sex, nausea, or fever.
Symptoms in men include
Discharge from your penis
A burning sensation when urinating
Burning or itching around the opening of your penis
Pain and swelling in one or both testicles (although this is less common)
If the chlamydia infects the rectum (in men or women), it can cause rectal pain, discharge, and/or bleeding.
How do I know if I have chlamydia?
There are lab tests to diagnose chlamydia. Your health care provider may ask you to provide a urine sample. For women, providers sometimes use (or ask you to use) a cotton swab to get a sample from your vagina to test for chlamydia.
Who should be tested for chlamydia?
You should go to your health provider for a test if you have symptoms of chlamydia, or if you have a partner who has a sexually transmitted disease. Pregnant women should get a test when they go to their first prenatal visit.
People at higher risk should get checked for chlamydia every year:
Sexually active women 25 and younger
Older women who have new or multiple sex partners, or a sex partner who has a sexually transmitted disease
Men who have sex with men (MSM)
What are the complications of chlamydia?
In women, an untreated infection can spread to your uterus and fallopian tubes, causing pelvic inflammatory disease (PID). PID can cause permanent damage to your reproductive system. This can lead to long-term pelvic pain, infertility, and ectopic pregnancy. Women who have had chlamydia infections more than once are at higher risk of serious reproductive health complications.
Men often don't have health problems from chlamydia. Sometimes it can infect the epididymis (the tube that carries sperm). This can cause pain, fever, and, rarely, infertility.
Both men and women can develop reactive arthritis because of a chlamydia infection. Reactive arthritis is a type of arthritis that happens as a "reaction" to an infection in the body.
Babies born to infected mothers can get eye infections and pneumonia from chlamydia. It may also make it more likely for your baby to be born too early.
Untreated chlamydia may also increase your chances of getting or giving HIV/AIDS.
What are the treatments for chlamydia?
Antibiotics will cure the infection. You may get a one-time dose of the antibiotics, or you may need to take medicine every day for 7 days. Antibiotics cannot repair any permanent damage that the disease has caused.
To prevent spreading the disease to your partner, you should not have sex until the infection has cleared up. If you got a one-time dose of antibiotics, you should wait 7 days after taking the medicine to have sex again. If you have to take medicine every day for 7 days, you should not have sex again until you have finished taking all of the doses of your medicine.
It is common to get a repeat infection, so you should get tested again about three months after treatment.
Can I prevent chlamydia?
The only sure way to prevent chlamydia is to not have vaginal, anal, or oral sex.
Correct usage of latex condoms greatly reduces, but does not eliminate, the risk of catching or spreading chlamydia.

Food or small objects can cause choking if they get caught in your throat and block your airway. This keeps oxygen from getting to your lungs and brain. If your brain goes without oxygen for more than four minutes, you could have brain damage or die.
Young children are at an especially high risk of choking. They can choke on foods like hot dogs, nuts and grapes, and on small objects like toy pieces and coins. Keep hazards out of their reach and supervise them when they eat.
When someone is choking, quick action can be lifesaving. Learn how to do back blows, the Heimlich maneuver (abdominal thrusts), and CPR.
Your liver makes a digestive juice called bile. Your gallbladder stores it between meals. When you eat, your gallbladder pushes the bile into tubes called bile ducts. They carry the bile to your small intestine. The bile helps break down fat. It also helps the liver get rid of toxins and wastes.
Bile duct cancer is rare. It can happen in the parts of the bile ducts that are outside or inside the liver. Cancer of the bile duct outside of the liver is much more common. Risk factors include having inflammation of the bile duct, ulcerative colitis, and some liver diseases.
Symptoms can include
Jaundice
Itchy skin
Fever
Abdominal pain
Tests to diagnose bile duct cancer may include a physical exam, imaging tests of the liver and bile ducts, blood tests, and a biopsy.
Treatments include surgery, radiation therapy, and chemotherapy.

Your liver makes a digestive juice called bile. Your gallbladder stores it between meals. When you eat, your gallbladder pushes the bile into tubes called bile ducts. They carry the bile to your small intestine. The bile helps break down fat. It also helps the liver get rid of toxins and wastes.
Different diseases can block the bile ducts and cause a problem with the flow of bile:
Gallstones, which can increase pressure in the gallbladder and cause a gallbladder attack. The pain usually lasts from one to several hours.
Cancer
Infections
Birth defects, such as biliary atresia. It is the most common reason for liver transplants in children in the United States.
Inflammation, which can cause scarring. Over time, this can lead to liver failure.

Your gallbladder is a pear-shaped organ under your liver. It stores bile, a fluid made by your liver to digest fat. As your stomach and intestines digest food, your gallbladder releases bile through a tube called the common bile duct. The duct connects your gallbladder and liver to your small intestine.
Your gallbladder is most likely to give you trouble if something blocks the flow of bile through the bile ducts. That is usually a gallstone. Gallstones form when substances in bile harden. Rarely, you can also get cancer in your gallbladder.
Many gallbladder problems get better with removal of the gallbladder. Fortunately, you can live without a gallbladder. Bile has other ways of reaching your small intestine.

Gallstone attacks usually happen after you eat. Signs of a gallstone attack may include nausea, vomiting, or pain in the abdomen, back, or just under the right arm.
Gallstones are most common among older adults, women, overweight people, Native Americans and Mexican Americans.
Gallstones are often found during imaging tests for other health conditions. If you do not have symptoms, you usually do not need treatment. The most common treatment is removal of the gallbladder. Fortunately, you can live without a gallbladder. Bile has other ways to reach your small intestine.

Cholera is a bacterial infection that causes diarrhea. The cholera bacterium is usually found in water or food contaminated by feces (poop). Cholera is rare in the US. You may get it if you travel to parts of the world with inadequate water treatment and poor sanitation, and lack of sewage treatment. Outbreaks can also happen after disasters. The disease is not likely to spread directly from one person to another.
Often the infection is mild or without symptoms, but sometimes it can be severe. Severe symptoms include profuse watery diarrhea, vomiting, and leg cramps. In severe cases, rapid loss of body fluids leads to dehydration and shock. Without treatment, death can occur within hours.
Doctors diagnose cholera with a stool sample or rectal swab. Treatment includes replacing fluid and salts and sometimes antibiotics.
Anyone who thinks they may have cholera should seek medical attention immediately. Dehydration can be rapid so fluid replacement is essential.

Cholesterol is a waxy, fat-like substance that occurs naturally in all parts of the body. Your body needs some cholesterol to work properly. But if you have too much in your blood, it can combine with other substances in the blood and stick to the walls of your arteries. This is called plaque. Plaque can narrow your arteries or even block them.
High levels of cholesterol in the blood can increase your risk of heart disease. Your cholesterol levels tend to rise as you get older. There are usually no signs or symptoms that you have high blood cholesterol, but it can be detected with a blood test. You are likely to have high cholesterol if members of your family have it, if you are overweight or if you eat a lot of fatty foods.
You can lower your cholesterol by exercising more and eating more fruits and vegetables. You also may need to take medicine to lower your cholesterol.

Gout is a common, painful form of arthritis. It causes swollen, red, hot and stiff joints.
Gout happens when uric acid builds up in your body. Uric acid comes from the breakdown of substances called purines. Purines are in your body's tissues and in foods, such as liver, dried beans and peas, and anchovies. Normally, uric acid dissolves in the blood. It passes through the kidneys and out of the body in urine. But sometimes uric acid can build up and form needle-like crystals. When they form in your joints, it is very painful. The crystals can also cause kidney stones.
Often, gout first attacks your big toe. It can also attack ankles, heels, knees, wrists, fingers, and elbows. At first, gout attacks usually get better in days. Eventually, attacks last longer and happen more often.
You are more likely to get gout if you
Are a man
Have family member with gout
Are overweight
Drink alcohol
Eat too many foods rich in purines
Gout can be hard to diagnose. Your doctor may take a sample of fluid from an inflamed joint to look for crystals. You can treat gout with medicines.
Pseudogout has similar symptoms and is sometimes confused with gout. However, it is caused by calcium phosphate, not uric acid.

Your knee joint is made up of bone, cartilage, ligaments and fluid. Muscles and tendons help the knee joint move. When any of these structures is hurt or diseased, you have knee problems. Knee problems can cause pain and difficulty walking.
Knee problems are very common, and they occur in people of all ages. Knee problems can interfere with many things, from participation in sports to simply getting up from a chair and walking. This can have a big impact on your life.
The most common disease affecting the knee is osteoarthritis. The cartilage in the knee gradually wears away, causing pain and swelling.
Injuries to ligaments and tendons also cause knee problems. A common injury is to the anterior cruciate ligament (ACL). You usually injure your ACL by a sudden twisting motion. ACL and other knee injuries are common sports injuries.
Treatment of knee problems depends on the cause. In some cases your doctor may recommend knee replacement.

We all want high-quality health care, but it's hard to know how to choose. There are many things to consider, including
What your insurance covers
Whether a health care provider or service is accredited
The location of a service
Hours that the service is available
Whether you like a health care provider's personality
On this page you'll find information to help you choose a health care provider or service.
Imagine if parts of your body moved when you didn't want them to. If you have a movement disorder, you experience these kinds of impaired movement. Dyskinesia is abnormal uncontrolled movement and is a common symptom of many movement disorders. Tremors are a type of dyskinesia.
Nerve diseases cause many movement disorders, such as Parkinson's disease. Other causes include injuries, autoimmune diseases, infections and certain medicines. Many movement disorders are inherited, which means they run in families.
Treatment varies by disorder. Medicine can cure some disorders. Others get better when an underlying disease is treated. Often, however, there is no cure. In that case, the goal of treatment is to improve symptoms and relieve pain.
Prenatal testing provides information about your baby's health before he or she is born. Some routine tests during pregnancy also check on your health. At your first prenatal visit, your healthcare provider will test for a number of things, including problems with your blood, signs of infections, and whether you are immune to rubella (German measles) and chickenpox.
Throughout your pregnancy, your healthcare provider may suggest a number of other tests, too. Some tests are suggested for all women, such as screenings for gestational diabetes, Down syndrome, and HIV. Other tests might be offered based on your:
Age
Personal or family health history
Ethnic background
Results of routine tests
Some tests are screening tests. They detect risks for or signs of possible health problems in you or your baby. Based on screening test results, your doctor might suggest diagnostic tests. Diagnostic tests confirm or rule out health problems in you or your baby.

Minerals are important for your body to stay healthy. Your body uses minerals for many different jobs, including keeping your bones, muscles, heart, and brain working properly. Minerals are also important for making enzymes and hormones.
There are two kinds of minerals: macrominerals and trace minerals. You need larger amounts of macrominerals. They include calcium, phosphorus, magnesium, sodium, potassium, chloride and sulfur. You only need small amounts of trace minerals. They include iron, manganese, copper, iodine, zinc, cobalt, fluoride and selenium.
Most people get the amount of minerals they need by eating a wide variety of foods. In some cases, your doctor may recommend a mineral supplement. People who have certain health problems or take some medicines may need to get less of one of the minerals. For example, people with chronic kidney disease need to limit foods that are high in potassium.
Bronchitis is an inflammation of the bronchial tubes, the airways that carry air to your lungs. It causes a cough that often brings up mucus. It can also cause shortness of breath, wheezing, a low fever, and chest tightness. There are two main types of bronchitis: acute and chronic.
Chronic bronchitis is one type of COPD (chronic obstructive
pulmonary disease). The inflamed bronchial tubes produce a lot of mucus. This leads to coughing and difficulty breathing. Cigarette smoking is the most common cause. Breathing in air pollution, fumes, or dust over a long period of time may also cause it.
To diagnose chronic bronchitis, your doctor will look at your signs and symptoms and listen to your breathing. You may also have other tests.
Chronic bronchitis is a long-term condition that keeps coming back or never goes away completely. If you smoke, it is important to quit. Treatment can help with your symptoms. It often includes medicines to open your airways and help clear away mucus. You may also need oxygen therapy. Pulmonary rehabilitation may help you manage better in daily life.

Chronic fatigue syndrome (CFS) is a disorder that causes extreme fatigue. This fatigue is not the kind of tired feeling that goes away after you rest. Instead, it lasts a long time and limits your ability to do ordinary daily activities.
The main symptom of CFS is severe fatigue that lasts for 6 months or more. You also have at least four of these other symptoms:
Feeling unwell for more than 24 hours after physical activity
Muscle pain
Memory problems
Headaches
Pain in multiple joints
Sleep problems
Sore throat
Tender lymph nodes
CFS is hard to diagnose. There are no tests for it, and other illnesses can cause similar symptoms. Your doctor has to rule out other diseases before making a diagnosis of CFS.
No one knows what causes CFS. It is most common in women in their 40s and 50s, but anyone can have it. It can last for years. There is no cure for CFS, so the goal of treatment is to improve symptoms. CFS affects people in different ways. You should work with your doctors to create a treatment program that best meets your own needs. It may include therapies to manage your symptoms, such as medicines to treat pain, sleep disorders, and other problems. It may also include coping techniques, and ways of managing your daily activities.

Leukemia is cancer of the white blood cells. White blood cells help your body fight infection. Your blood cells form in your bone marrow. In leukemia, the bone marrow produces abnormal white blood cells. These cells crowd out the healthy blood cells, making it hard for blood to do its work. In chronic myeloid leukemia (CML), there are too many granulocytes, a type of white blood cell.
Most people with CML have a gene mutation (change) called the Philadelphia chromosome.
Sometimes CML does not cause any symptoms. If you have symptoms, they may include:
Fatigue
Weight loss
Night sweats
Fever
Pain or a feeling of fullness below the ribs on the left side
Tests that examine the blood and bone marrow diagnose CML. Treatments include chemotherapy, stem cell transplants, infusion of donated white blood cells following stem cell transplants, surgery to remove the spleen, and biologic and targeted therapies. Biologic therapy boosts your body's own ability to fight cancer. Targeted therapy uses substances that attack cancer cells without harming normal cells.

Your immune system is a complex network of cells, tissues, and organs that work together to defend against germs. It helps your body to recognize these "foreign" invaders. Then its job is to keep them out, or if it can't, to find and destroy them.
If your immune system cannot do its job, the results can be serious. Disorders of the immune system include
Allergy and asthma - immune responses to substances that are usually not harmful
Immune deficiency diseases - disorders in which the immune system is missing one or more of its parts
Autoimmune diseases - diseases causing your immune system to attack your own body's cells and tissues by mistake

Having a long-term, or chronic, illness can disrupt your life in many ways. You may often
be tired and in pain. Your illness might affect your appearance or your physical abilities
and independence. You may not be able to work, causing financial problems.
For children, chronic illnesses can be frightening, because they may not understand why
this is happening to them. These changes can cause stress, anxiety and anger. If they do, it is important to seek
help. A trained counselor can help you develop strategies to regain a feeling of control.
Support groups might help, too. You will find that you are not alone, and you may learn
some new tips on how to cope.
You have two kidneys, each about the size of your fist. Their main job is to filter wastes and excess water out of your blood to make urine. They also keep the body's chemical balance, help control blood pressure, and make hormones.
Chronic kidney disease (CKD) means that your kidneys are damaged and can't filter blood as they should. This damage can cause wastes to build up in your body. It can also cause other problems that can harm your health. Diabetes and high blood pressure are the most common causes of CKD.
The kidney damage occurs slowly over many years. Many people don't have any symptoms until their kidney disease is very advanced. Blood and urine tests are the only way to know if you have kidney disease.
Treatment may include medicines to lower blood pressure, control blood glucose, and lower blood cholesterol. CKD can get worse over time. CKD may lead to kidney failure. The only treatment options for kidney failure are dialysis or a kidney transplantation.
You can take steps to keep your kidneys healthier longer:
Choose foods with less salt (sodium)
Keep your blood pressure below 130/80
Keep your blood glucose in the target range, if you have diabetes

In leukemia, the bone marrow produces abnormal white blood cells. These cells crowd out the healthy blood cells, making it hard for blood to do its work. In chronic lymphocytic leukemia (CLL), there are too many lymphocytes, a type of white blood cell.
CLL is the second most common type of leukemia in adults. It often occurs during or after middle age, and is rare in children.
Usually CLL does not cause any symptoms. If you have symptoms, they may include
Painless swelling of the lymph nodes in the neck, underarm, stomach, or groin
Fatigue
Pain or a feeling of fullness below the ribs
Fever and infection
Weight loss
Tests that examine the blood, bone marrow, and lymph nodes diagnose CLL. Your doctor may choose to just monitor you until symptoms appear or change. Treatments include radiation therapy, chemotherapy, surgery to remove the spleen, and targeted therapy. Targeted therapy uses substances that attack cancer cells without harming normal cells.

COPD (chronic obstructive pulmonary disease) makes it hard for you to breathe. The two main types are chronic bronchitis and emphysema. The main cause of COPD is long-term exposure to substances that irritate and damage the lungs. This is usually cigarette smoke. Air pollution, chemical fumes, or dust can also cause it.
At first, COPD may cause no symptoms or only mild symptoms. As the disease gets worse, symptoms usually become more severe. They include
A cough that produces a lot of mucus
Shortness of breath, especially with physical activity
Wheezing
Chest tightness
Doctors use lung function tests, imaging tests, and blood tests to diagnose COPD. There is no cure. Treatments may relieve symptoms. They include medicines, oxygen therapy, surgery, or a lung transplant. Quitting smoking is the most important step you can take to treat COPD.

Pain is a feeling set off in the nervous system. Acute pain lets you know that you may be injured or have a problem you need to take care of. Chronic pain is different. The pain signals go on for weeks, months, or even years. The original cause may have been an injury or infection. There may be an ongoing cause of pain, such as arthritis or cancer. But in some cases there is no clear cause.
Problems that cause chronic pain include
Headache
Low back strain
Cancer
Arthritis
Pain from nerve damage
Chronic pain usually cannot be cured. But treatments can help. They include medicines, acupuncture, electrical stimulation and surgery. Other treatments include psychotherapy, relaxation and meditation therapy, biofeedback, and behavior modification.

The pancreas is a large gland behind the stomach and close to the first part of the small intestine. It secretes digestive juices into the small intestine through a tube called the pancreatic duct. The pancreas also releases the hormones insulin and glucagon into the bloodstream.
Pancreatitis is inflammation of the pancreas. It happens when digestive enzymes start digesting the pancreas itself. Pancreatitis can be acute or chronic. Either form is serious and can lead to complications.
Acute pancreatitis occurs suddenly and usually goes away in a few days with treatment. It is often caused by gallstones. Common symptoms are severe pain in the upper abdomen, nausea, and vomiting. Treatment is usually a few days in the hospital for intravenous (IV) fluids, antibiotics, and medicines to relieve pain.
Chronic pancreatitis does not heal or improve. It gets worse over time and leads to permanent damage. The most common cause is heavy alcohol use. Other causes include cystic fibrosis and other inherited disorders, high levels of calcium or fats in the blood, some medicines, and autoimmune conditions. Symptoms include nausea, vomiting, weight loss, and oily stools. Treatment may also be a few days in the hospital for intravenous (IV) fluids, medicines to relieve pain, and nutritional support. After that, you may need to start taking enzymes and eat a special diet. It is also important to not smoke or drink alcohol.

Eosinophils are a type of white blood cell. They help fight off infections and play a role in your body's immune response. They can also build up and cause inflammation.
Normally your blood doesn't have a large number of eosinophils. Your body may produce more of them in response to
Allergic disorders
Skin conditions
Parasitic and fungal infections
Autoimmune diseases
Some cancers
Bone marrow disorders
In some conditions, the eosinophils can move outside the bloodstream and build up in organs and tissues. Treatment of the problem depends on the cause.
A scar is a permanent patch of skin that grows over a wound. It forms when your body heals itself after a cut, scrape, burn, or sore. You can also get scars from surgery that cuts through the skin, infections like chickenpox, or skin conditions like acne. Scars are often thicker, as well as pinker, redder, or shinier, than the rest of your skin.
How your scar looks depends on
How big and deep your wound is
Where it is
How long it takes to heal
Your age
Your inherited tendency to scar
Scars usually fade over time but never go away completely. If the way a scar looks bothers you, various treatments might minimize it. These include surgical revision, dermabrasion, laser treatments, injections, chemical peels, and creams.
The vascular system is the body's network of blood vessels. It includes the arteries, veins and capillaries that carry blood to and from the heart. Problems of the vascular system are common and can be serious. Arteries can become thick and stiff, a problem called atherosclerosis. Blood clots can clog vessels and block blood flow to the heart or brain. Weakened blood vessels can burst, causing bleeding inside the body.
You are more likely to have vascular disease as you get older. Other factors that make vascular disease more likely include
Family history of vascular or heart diseases
Pregnancy
Illness or injury
Long periods of sitting or standing still
Any condition that affects the heart and blood vessels, such as diabetes or high cholesterol
Smoking
Obesity
Losing weight, eating healthy foods, being active and not smoking can help vascular disease. Other treatments include medicines and surgery.
Circumcision is a surgical procedure to remove the foreskin, the skin that covers the tip of the penis. In the United States, it is often done before a new baby leaves the hospital. According to the American Academy of Pediatrics (AAP), there are medical benefits and risks to circumcision. Possible benefits include a lower risk of urinary tract infections, penile cancer, and sexually transmitted diseases. There is a low risk of bleeding or infection. The baby might also feel some pain.
The AAP said that because of the possible benefits, parents should have the option to circumcise their sons. They recommend that parents discuss circumcision with their baby's health care provider. Parents should make their decision based on the benefits and risks, as well as their own religious, cultural, and personal preferences.
Cirrhosis is scarring of the liver. Scar tissue forms because of injury or long-term disease. Scar tissue cannot do what healthy liver tissue does - make protein, help fight infections, clean the blood, help digest food and store energy. Cirrhosis can lead to
Easy bruising or bleeding, or nosebleeds
Swelling of the abdomen or legs
Extra sensitivity to medicines
High blood pressure in the vein entering the liver
Enlarged veins called varices in the esophagus and stomach. Varices can bleed suddenly.
Kidney failure
Jaundice
Severe itching
Gallstones
A small number of people with cirrhosis get liver cancer.
Your doctor will diagnose cirrhosis with blood tests, imaging tests, or a biopsy.
Cirrhosis has many causes. In the United States, the most common causes are chronic alcoholism and hepatitis. Nothing will make the scar tissue disappear, but treating the cause can keep it from getting worse. If too much scar tissue forms, you may need to consider a liver transplant.

Creutzfeldt-Jakob disease (CJD) is a rare, degenerative brain disorder. Symptoms usually start around age 60. Memory problems, behavior changes, vision problems, and poor muscle coordination progress quickly to dementia, coma, and death. Most patients die within a year.
The three main categories of CJD are
Sporadic CJD, which occurs for no known reason
Hereditary CJD, which runs in families
Acquired CJD, which occurs from contact with infected tissue, usually during a medical procedure
Cattle can get a disease related to CJD called bovine spongiform encephalopathy (BSE) or "mad cow disease." There is concern that people can get a variant of CJD from eating beef from an infected animal, but there is no direct proof to support this.

Gonorrhea is a sexually transmitted disease. It is most common in young adults. The bacteria that cause gonorrhea can infect the genital tract, mouth, or anus. You can get gonorrhea during vaginal, oral, or anal sex with an infected partner. A pregnant woman can pass it to her baby during childbirth.
Gonorrhea does not always cause symptoms. In men, gonorrhea can cause pain when urinating and discharge from the penis. If untreated, it can cause problems with the prostate and testicles.
In women, the early symptoms of gonorrhea often are mild. Later, it can cause bleeding between periods, pain when urinating, and increased discharge from the vagina. If untreated, it can lead to pelvic inflammatory disease, which causes problems with pregnancy and infertility.
Your health care provider will diagnose gonorrhea with lab tests. Treatment is with antibiotics. Treating gonorrhea is becoming more difficult because drug-resistant strains are increasing. Correct usage of latex condoms greatly reduces, but does not eliminate, the risk of catching or spreading gonorrhea.

Your legs are made up of bones, blood vessels, muscles, and other connective tissue. They are important for motion and standing. Playing sports, running, falling, or having an accident can damage your legs. Common leg injuries include sprains and strains, joint dislocations, and fractures.
These injuries can affect the entire leg, or just the foot, ankle, knee, or hip. Certain diseases also lead to leg problems. For example, knee osteoarthritis, common in older people, can cause pain and limited motion. Problems in your veins in your legs can lead to varicose veins or deep vein thrombosis.
Your shoulder joint is composed of three bones: the clavicle (collarbone), the scapula (shoulder blade), and the humerus (upper arm bone). Your shoulders are the most movable joints in your body. They can also be unstable because the ball of the upper arm is larger than the shoulder socket that holds it. To remain in a stable or normal position, the shoulder must be anchored by muscles, tendons, and ligaments.
Because your shoulder can be unstable, it can be easily injured. Common problems include
Sprains and strains
Dislocations
Separations
Tendinitis
Bursitis
Torn rotator cuffs
Frozen shoulder
Fractures
Arthritis
Health care providers diagnose shoulder problems by using your medical history, a physical exam, and imaging tests.
Often, the first treatment for shoulder problems is RICE. This stands for Rest, Ice, Compression, and Elevation. Other treatments include exercise and medicines to reduce pain and swelling. If those don't work, you may need surgery.

Cleft lip and cleft palate are birth defects that occur when a baby's lip or mouth do not form properly. They happen early during pregnancy. A baby can have a cleft lip, a cleft palate, or both.
A cleft lip happens if the tissue that makes up the lip does not join completely before birth. This causes an opening in the upper lip. The opening can be a small slit or a large opening that goes through the lip into the nose. It can be on one or both sides of the lip or, rarely, in the middle of the lip.
Children with a cleft lip also can have a cleft palate. The roof of the mouth is called the "palate." With a cleft palate, the tissue that makes up the roof of the mouth does not join correctly. Babies may have both the front and back parts of the palate open, or they may have only one part open.
Children with a cleft lip or a cleft palate often have problems with feeding and talking. They also might have ear infections, hearing loss, and problems with their teeth.
Often, surgery can close the lip and palate. Cleft lip surgery is usually done before age 12 months, and cleft palate surgery is done before 18 months. Many children have other complications. They may need additional surgeries, dental and orthodontic care, and speech therapy as they get older. With treatment, most children with clefts do well and lead a healthy life.

Spina bifida is a neural tube defect - a type of birth defect of the brain, spine, or spinal cord. It happens if the spinal column of the fetus doesn't close completely during the first month of pregnancy. This can damage the nerves and spinal cord. Screening tests during pregnancy can check for spina bifida. Sometimes it is discovered only after the baby is born.
The symptoms of spina bifida vary from person to person. Most people with spina bifida are of normal intelligence. Some people need assistive devices such as braces, crutches, or wheelchairs. They may have learning difficulties, urinary and bowel problems, or hydrocephalus, a buildup of fluid in the brain.
The exact cause of spina bifida is unknown. It seems to run in families. Taking folic acid can reduce the risk of having a baby with spina bifida. It's in most multivitamins. Women who could become pregnant should take it daily.

Climate is the average weather in a place over a period of time. Climate change is major change in temperature, rainfall, snow, or wind patterns lasting for many years. It can be caused by natural factors or by human activities. Today climate changes are occurring at an increasingly rapid rate.
Climate change can affect our health. It can lead to
More heat-related illness and deaths
More pollen, mold, and air pollution. This can cause an increase in allergies, asthma, and breathing problems.
Mosquitoes and other insects that carry diseases spreading to areas that used to be too cold for them.
More floods and rising sea levels. This can cause an increase in contamination of food and water.
More extreme weather events, such as hurricanes and wildfires. These can cause death, injuries, stress, and mental health problems.
Researchers are studying the best ways to lessen climate change and reduce its impact on our health.

Clinical trials are research studies that test how well new medical approaches work in people. Each study
answers scientific questions and tries to find better ways to prevent, screen for, diagnose, or treat a
disease. Clinical trials may also compare a new treatment to a treatment that is already available.
Every clinical trial has a protocol, or action plan, for conducting the trial. The plan describes what
will be done in the study, how it will be conducted, and why each part of the study is necessary. Each study
has its own rules about who can take part. Some studies need volunteers with a certain disease. Some need
healthy people. Others want just men or just women.
An Institutional Review Board (IRB) reviews, monitors, and approves many clinical trials. It is an independent committee of physicians, statisticians, and members of the community. Its role is to
Make sure that the study is ethical
Protect the rights and welfare of the participants
Make sure that the risks are reasonable when compared to the potential benefits
In the United States, a clinical trial must have an IRB if it is studying a drug, biological product, or medical device that the Food and Drug Administration (FDA) regulates, or it is funded or carried out by the federal government.

Leukemia is cancer of the white blood cells. White blood cells help your body fight infection. Your blood cells form in your bone marrow. In leukemia, the bone marrow produces abnormal white blood cells. These cells crowd out the healthy blood cells, making it hard for blood to do its work. In chronic lymphocytic leukemia (CLL), there are too many lymphocytes, a type of white blood cell.
CLL is the second most common type of leukemia in adults. It often occurs during or after middle age, and is rare in children.
Usually CLL does not cause any symptoms. If you have symptoms, they may include
Painless swelling of the lymph nodes in the neck, underarm, stomach, or groin
Fatigue
Pain or a feeling of fullness below the ribs
Fever and infection
Weight loss
Tests that examine the blood, bone marrow, and lymph nodes diagnose CLL. Your doctor may choose to just monitor you until symptoms appear or change. Treatments include radiation therapy, chemotherapy, surgery to remove the spleen, and targeted therapy. Targeted therapy uses substances that attack cancer cells without harming normal cells.

Cloning describes the processes used to create an exact genetic replica of another cell, tissue or organism. The copied material, which has the same genetic makeup as the original, is referred to as a clone. The most famous clone was a Scottish sheep named Dolly.
There are three different types of cloning:
Gene cloning, which creates copies of genes or segments of DNA
Reproductive cloning, which creates copies of whole animals
Therapeutic cloning, which creates embryonic stem cells. Researchers hope to use these cells to grow healthy tissue to replace injured or diseased tissues in the human body.

Clostridium difficile (C. difficile) is a bacterium that causes diarrhea and more serious intestinal conditions such as colitis. Symptoms include
Watery diarrhea (at least three bowel movements per day for two or more days)
Fever
Loss of appetite
Nausea
Abdominal pain or tenderness
You might get C. difficile disease if you have an illness that requires prolonged use of antibiotics. Increasingly, the disease can also be spread in the hospital. The elderly are also at risk. Treatment is with antibiotics.

Club drugs are group of psychoactive drugs. They act on the central nervous system and can cause changes in mood, awareness, and how you act. These drugs are often abused by young adults at all-night dance parties, dance clubs, and bars. They include
Methylenedioxymethamphetamine (MDMA), also known as Ecstasy XTC, X, E, Adam, Molly, Hug Beans, and Love Drug
Gamma-hydroxybutyrate (GHB), also known as G, Liquid Ecstasy, and Soap
Ketamine, also known as Special K, K, Vitamin K, and Jet
Rohypnol, also known as Roofies
Methamphetamine, also known as Speed, Ice, Chalk, Meth, Crystal, Crank, and Glass
Lysergic Acid Diethylamide (LSD), also known as Acid, Blotter, and Dots
Some of these drugs are approved for certain medical uses. Other uses of these drugs are abuse.
Club drugs are also sometimes used as "date rape" drugs, to make someone unable to say no to or fight back against sexual assault. Abusing these drugs can cause serious health problems and sometimes death. They are even more dangerous if you use them with alcohol.

Almost everyone has had a headache. Headache is the most common form of pain. It's a major reason people miss days at work or school or visit the doctor.
The most common type of headache is a tension headache. Tension headaches are due to tight muscles in your shoulders, neck, scalp and jaw. They are often related to stress, depression or anxiety. You are more likely to get tension headaches if you work too much, don't get enough sleep, miss meals, or use alcohol.
Other common types of headaches include migraines, cluster headaches, and sinus headaches. Most people can feel much better by making lifestyle changes, learning ways to relax and taking pain relievers.
Not all headaches require a doctor's attention. But sometimes headaches warn of a more serious disorder. Let your health care provider know if you have sudden, severe headaches. Get medical help right away if you have a headache after a blow to your head, or if you have a headache along with a stiff neck, fever, confusion, loss of consciousness, or pain in the eye or ear.

Leukemia is cancer of the white blood cells. White blood cells help your body fight infection. Your blood cells form in your bone marrow. In leukemia, the bone marrow produces abnormal white blood cells. These cells crowd out the healthy blood cells, making it hard for blood to do its work. In chronic myeloid leukemia (CML), there are too many granulocytes, a type of white blood cell.
Most people with CML have a gene mutation (change) called the Philadelphia chromosome.
Sometimes CML does not cause any symptoms. If you have symptoms, they may include:
Fatigue
Weight loss
Night sweats
Fever
Pain or a feeling of fullness below the ribs on the left side
Tests that examine the blood and bone marrow diagnose CML. Treatments include chemotherapy, stem cell transplants, infusion of donated white blood cells following stem cell transplants, surgery to remove the spleen, and biologic and targeted therapies. Biologic therapy boosts your body's own ability to fight cancer. Targeted therapy uses substances that attack cancer cells without harming normal cells.

Cytomegalovirus (CMV) is a virus found around the world. It is related to the viruses that cause chickenpox and infectious mononucleosis (mono). Between 50 percent and 80 percent of adults in the United States have had a CMV infection by age 40. Once CMV is in a person's body, it stays there for life.
CMV is spread through close contact with body fluids. Most people with CMV don't get sick and don't know that they've been infected. But infection with the virus can be serious in babies and people with weak immune systems. If a woman gets CMV when she is pregnant, she can pass it on to her baby. Usually the babies do not have health problems. But some babies can develop lifelong disabilities.
A blood test can tell whether a person has ever been infected with CMV. Most people with CMV don't need treatment. If you have a weakened immune system, your doctor may prescribe antiviral medicine. Good hygiene, including proper hand washing, may help prevent infections.

Carbon monoxide (CO) is a gas that has no odor or color. But it is very dangerous. It can cause sudden illness and death. CO is found in combustion fumes, such as those made by cars and trucks, lanterns, stoves, gas ranges and heating systems. CO from these fumes can build up in places that don't have a good flow of fresh air. You can be poisoned by breathing them in. The most common symptoms of CO poisoning are Headache Dizziness Weakness Nausea Vomiting Chest pain Confusion It is often hard to tell if someone has CO poisoning, because the symptoms may be like those of other illnesses. People who are sleeping or intoxicated can die from CO poisoning before they have symptoms. A CO detector can warn you if you have high levels of CO in your home. Centers for Disease Control and Prevention
Interstitial lung disease is the name for a large group of diseases that inflame or scar the lungs. The inflammation and scarring make it hard to get enough oxygen. The scarring is called pulmonary fibrosis.
Breathing in dust or other particles in the air is responsible for some types of interstitial lung diseases. Specific types include
Black lung disease among coal miners, from inhaling coal dust
Farmer's lung, from inhaling farm dust
Asbestosis, from inhaling asbestos fibers
Siderosis, from inhaling iron from mines or welding fumes
Silicosis, from inhaling silica dust
Other causes include autoimmune diseases or occupational exposures to molds, gases, or fumes. Some types of interstitial lung disease have no known cause.
Treatment depends on the type of exposure and the stage of the disease. It may involve medicines, oxygen therapy, or a lung transplant in severe cases.
Cocaine is a white powder. It can be snorted up the nose or mixed with water and injected with a needle. Cocaine can also be made into small white rocks, called crack. Crack is smoked in a small glass pipe.
Cocaine speeds up your whole body. You may feel full of energy, happy, and excited. But then your mood can change. You can become angry, nervous, and afraid that someone's out to get you. You might do things that make no sense. After the "high" of the cocaine wears off, you can "crash" and feel tired and sad for days. You also get a strong craving to take the drug again to try to feel better.
No matter how cocaine is taken, it is dangerous. Some of the most common serious problems include heart attack and stroke. You are also at risk for HIV/AIDS and hepatitis, from sharing needles or having unsafe sex. Cocaine is more dangerous when combined with other drugs or alcohol.
It is easy to lose control over cocaine use and become addicted. Then, even if you get treatment, it can be hard to stay off the drug. People who stopped using cocaine can still feel strong cravings for the drug, sometimes even years later.

Valley Fever is a disease caused by a fungus (or mold) called Coccidioides. The fungi live in the soil of dry areas like the southwestern U.S. You get it from inhaling the spores of the fungus. The infection cannot spread from person to person.
Anyone can get Valley Fever. But it's most common among older adults, especially those 60 and older. People who have recently moved to an area where it occurs are at highest risk for infection. Other people at higher risk include
Workers in jobs that expose them to soil dust. These include construction workers, agricultural workers, and military forces doing field training.
African Americans and Asians
Women in their third trimester of pregnancy
People with weak immune systems
Valley Fever is often mild, with no symptoms. If you have symptoms, they may include a flu-like illness, with fever, cough, headache, rash, and muscle aches. Most people get better within several weeks or months. A small number of people may develop a chronic lung or widespread infection.
Valley Fever is diagnosed by testing your blood, other body fluids, or tissues. Many people with the acute infection get better without treatment. In some cases, doctors may prescribe antifungal drugs for acute infections. Severe infections require antifungal drugs.

The tailbone is the small bone at the bottom of your backbone, or spine. Tailbone disorders include tailbone injuries, pain, infections, cysts and tumors. You rarely break your tailbone. Instead, most injuries cause bruises or pulled ligaments. A backward fall onto a hard surface, such as slipping on ice, is the most common cause of such injuries. Symptoms of various tailbone disorders include pain in the tailbone area, pain upon sitting, pain or numbness in the arms or legs due to pressure on nerves in the tailbone area, and a mass or growth you can see or feel.
A cochlear implant is a small, complex electronic device that can help to provide a sense of sound. People who are profoundly deaf or severely hard-of-hearing can get help from them. The implant consists of two parts. One part sits on the outside of the body, behind the ear. A second part is surgically placed under the skin.
An implant does not restore normal hearing. It can help a person understand speech. Children and adults can benefit from them.

Frostbite is an injury to the body that is caused by freezing. It most often affects the nose, ears, cheeks, chin, fingers, or toes. Frostbite can permanently damage the body, and severe cases can lead to amputation.
If you have frostbite, the skin in that area may turn white or grayish-yellow. It may feel firm or waxy when you touch it. The area will also feel numb.
If you have symptoms of frostbite, seek medical care. But if immediate medical care isn't available, here are steps to take:
Get into a warm room as soon as possible.
If possible, do not walk on frostbitten feet or toes. Walking increases the damage.
Put the affected area in warm - not hot - water.
You can also warm the affected area using body heat. For example, use your armpit to warm frostbitten fingers.
Don't rub the frostbitten area with snow or massage it at all. This can cause more damage.
Don't use a heating pad, heat lamp, or the heat of a stove, fireplace, or radiator for warming. Since frostbite makes an area numb, you could burn it.

Sneezing, sore throat, a stuffy nose, coughing -- everyone knows the symptoms of the common cold. It is probably the most common illness. Every year, adults get about 2-3 colds, and children get even more.
What can you do for your cold or cough symptoms? Besides drinking lots of fluids and getting plenty of rest, you may decide to take medicines. There are lots of different cold and cough medicines, and they do different things.
Nasal decongestants - unclog a stuffy nose
Cough suppressants - quiet a cough
Expectorants - loosen mucus so you can cough it up
Antihistamines - stop runny noses and sneezing
Pain relievers - ease fever, headaches, and minor aches and pains
Before taking these medicines, read the labels carefully. Many cold and cough medicines contain the same active ingredients. For example, taking too much of certain pain relievers can lead to serious injury. Do not give cold or cough medicines to children under four, and don't give aspirin to children. Finally, antibiotics won't help a cold.

Cold sores are caused by a contagious virus called herpes simplex virus (HSV). There are two types of HSV. Type 1 usually causes oral herpes, or cold sores. Type 1 herpes virus infects more than half of the U.S. population by the time they reach their 20s. Type 2 usually affects the genital area
Some people have no symptoms from the infection. But others develop painful and unsightly cold sores. Cold sores usually occur outside the mouth, on or around the lips. When they are inside the mouth, they are usually on the gums or the roof of the mouth. They are not the same as canker sores, which are not contagious.
There is no cure for cold sores. They normally go away on their own in a few weeks. Antiviral medicines can help them heal faster. They can also help to prevent cold sores in people who often get them. Other medicines can help with the pain and discomfort of the sores. These include ointments that numb the blisters, soften the crusts of the sores, or dry them out. Protecting your lips from the sun with sunblock lip balm can also help.
Sneezing, sore throat, a stuffy nose, coughing - everyone knows the symptoms of
the common cold. It is probably the most common illness. In the course of a year, people in
the United States suffer 1 billion colds. You can get a cold by touching your eyes or nose after you touch surfaces with cold
germs on them. You can also inhale the germs. Symptoms usually begin 2 or 3 days after
infection and last 2 to 14 days. Washing your hands and staying away from people with colds
will help you avoid colds. There is no cure for the common cold. For relief, try Getting plenty of rest Drinking fluids Gargling with warm salt water Using cough drops or throat sprays Taking over-the-counter pain or cold medicines However, do not give aspirin to children. And do not give cough medicine to children under four. NIH: National Institute of Allergy and Infectious Diseases
It is hard when your baby is sick. Common health problems in babies include colds, coughs, fevers, and vomiting. Babies also commonly have skin problems, like diaper rash or cradle cap.
Many of these problems are not serious. It is important to know how to help your sick baby, and to know the warning signs for more serious problems. Trust your intuition - if you are worried about your baby, call your health care provider right away.
Ulcerative colitis (UC) is a disease that causes inflammation and sores, called ulcers, in the lining of the rectum and colon. It is one of a group of diseases called inflammatory bowel disease.
UC can happen at any age, but it usually starts between the ages of 15 and 30. It tends to run in families. The most common symptoms are pain in the abdomen and blood or pus in diarrhea. Other symptoms may include
Anemia
Severe tiredness
Weight loss
Loss of appetite
Bleeding from the rectum
Sores on the skin
Joint pain
Growth failure in children
About half of people with UC have mild symptoms.
Doctors use blood tests, stool tests, colonoscopy or sigmoidoscopy, and imaging tests to diagnose UC. Several types of drugs can help control it. Some people have long periods of remission, when they are free of symptoms. In severe cases, doctors must remove the colon.

A collapsed lung happens when air enters the pleural space, the area between the lung and the chest wall. If it is a total collapse, it is called pneumothorax. If only part of the lung is affected, it is called atelectasis.
Causes of a collapsed lung include
Lung diseases such as pneumonia or lung cancer
Being on a breathing machine
Surgery on the chest or abdomen
A blocked airway
If only a small area of the lung is affected, you may not have symptoms. If a large area is affected, you may feel short of breath and have a rapid heart rate.
A chest x-ray can tell if you have it. Treatment depends on the underlying cause.

Your shoulder joint is composed of three bones: the clavicle (collarbone), the scapula (shoulder blade), and the humerus (upper arm bone). Your shoulders are the most movable joints in your body. They can also be unstable because the ball of the upper arm is larger than the shoulder socket that holds it. To remain in a stable or normal position, the shoulder must be anchored by muscles, tendons, and ligaments.
Because your shoulder can be unstable, it can be easily injured. Common problems include
Sprains and strains
Dislocations
Separations
Tendinitis
Bursitis
Torn rotator cuffs
Frozen shoulder
Fractures
Arthritis
Health care providers diagnose shoulder problems by using your medical history, a physical exam, and imaging tests.
Often, the first treatment for shoulder problems is RICE. This stands for Rest, Ice, Compression, and Elevation. Other treatments include exercise and medicines to reduce pain and swelling. If those don't work, you may need surgery.

The colon and rectum are part of the large intestine. Colorectal cancer occurs when tumors form in the lining of the large intestine. It is common in both men and women. The risk of developing colorectal cancer rises after age 50. You're also more likely to get it if you have colorectal polyps, a family history of colorectal cancer, ulcerative colitis or Crohn's disease, eat a diet high in fat, or smoke.
Symptoms of colorectal cancer include
Diarrhea or constipation
A feeling that your bowel does not empty completely
Blood (either bright red or very dark) in your stool
Stools that are narrower than usual
Frequent gas pains or cramps, or feeling full or bloated
Weight loss with no known reason
Fatigue
Nausea or vomiting
Because you may not have symptoms at first, it's important to have screening tests. Everyone over 50 should get screened. Tests include colonoscopy and tests for blood in the stool. Treatments for colorectal cancer include surgery, chemotherapy, radiation, or a combination. Surgery can usually cure it when it is found early.
NIH: National Cancer Institute
Your colon, also known as the large intestine, is part of your digestive system. It's a long, hollow tube at the end of your digestive tract where your body makes and stores stool. Many disorders affect the colon's ability to work properly. Some of these include Colorectal cancer Colonic polyps - extra tissue growing in the colon that can become cancerous Ulcerative colitis - ulcers of the colon and rectum Diverticulitis - inflammation or infection of pouches in the colon Irritable bowel syndrome - an uncomfortable condition causing abdominal cramping and other symptoms Treatment for colonic diseases varies greatly depending on the disease and its severity. Treatment may involve diet, medicines and in some cases, surgery. NIH: National Institute of Diabetes and Digestive and Kidney Diseases
A polyp is an extra piece of tissue that grows inside your body. Colonic polyps grow in the large intestine, or colon. Most polyps are not dangerous. However, some polyps may turn into cancer or already be cancer. To be safe, doctors remove polyps and test them. Polyps can be removed when a doctor examines the inside of the large intestine during a colonoscopy.
Anyone can get polyps, but certain people are more likely than others. You may have a greater chance of getting polyps if you
Are over age 50
Have had polyps before
Have a family member with polyps
Have a family history of colon cancer
Most colon polyps do not cause symptoms. If you have symptoms, they may include blood on your underwear or on toilet paper after a bowel movement, blood in your stool, or constipation or diarrhea lasting more than a week.
NIH: National Institute of Diabetes and Digestive and Kidney Diseases
Colonoscopy and sigmoidoscopy are procedures that let your doctor look inside your large intestine. They use instruments called scopes. Scopes have a tiny camera attached to a long, thin tube. The procedures let your doctor see things such as inflamed tissue, abnormal growths, and ulcers.
Colonoscopy checks your entire colon and rectum. Sigmoidoscopy checks the rectum and the lower colon only.
Your doctor may recommend one of these procedures
To look for early signs of cancer in the colon and rectum. It may be part of a routine screening, which usually starts at age 50.
To look for causes of unexplained changes in bowel habits
To evaluate symptoms like abdominal pain, rectal bleeding, and weight loss
Your doctor can also remove polyps from your colon during these procedures.
You will get written bowel prep instructions to follow at home before the procedure. The bowel prep cleans out the intestine so your doctor can see everything clearly. During a colonoscopy, you get medicines to keep you relaxed. You usually do not need them for a sigmoidoscopy.

Most of us see our world in color. We enjoy looking at a lush green lawn or a red rose in full bloom. If you have a color vision defect, you may see these colors differently than most people. There are three main kinds of color vision defects. Red-green color vision defects are the most common. This type occurs in men more than in women. The other major types are blue-yellow color vision defects and a complete absence of color vision. Most of the time, color blindness is genetic. There is no treatment, but most people adjust and the condition doesn't limit their activities.
If you spend time outdoors or have pets that go outdoors, you need to beware of ticks. Ticks are small bloodsucking parasites. Many species transmit diseases to animals and people. Some of the diseases you can get from a tick bite are Lyme disease, ehrlichiosis, Rocky Mountain spotted fever and tularemia. Some ticks are so small that they can be difficult to see. Ticks may get on you if you walk through areas where they live, such as tall grass, leaf litter or shrubs. Tick-borne diseases occur worldwide, including in your own backyard. To help protect yourself and your family, you should Use a chemical repellent with DEET, permethrin or picaridin Wear light-colored protective clothing Tuck pant legs into socks Avoid tick-infested areas Check yourself, your children and your pets daily for ticks and carefully remove any ticks you find

An ostomy is surgery to create an opening (stoma) from an area inside the body to the outside. It treats certain diseases of the digestive or urinary systems. It can be permanent, when an organ must be removed. It can be temporary, when the organ needs time to heal. The organ could be the small intestine, colon, rectum, or bladder. With an ostomy, there must be a new way for wastes to leave the body.
There are many different types of ostomy. Some examples are
Ileostomy - the bottom of the small intestine (ileum) is attached to the stoma. This bypasses the colon, rectum and anus.
Colostomy - the colon is attached to the stoma. This bypasses the rectum and the anus.
Urostomy - the tubes that carry urine to the bladder are attached to the stoma. This bypasses the bladder.

A coma is a deep state of unconsciousness. An individual in a coma is alive but unable to move or respond to his or her environment. Coma may occur as a complication of an underlying illness, or as a result of injuries, such as brain injury.
A coma rarely lasts more than 2 to 4 weeks. The outcome for coma depends on the cause, severity, and site of the damage. People may come out of a coma with physical, intellectual, and psychological problems. Some people may remain in a coma for years or even decades. For those people, the most common cause of death is infection, such as pneumonia.

Infectious diseases kill more people worldwide than any other single cause. Infectious
diseases are caused by germs. Germs are tiny living things that are found everywhere - in
air, soil and water. You can get infected by touching, eating, drinking or breathing something that contains a germ. Germs can also spread through animal and insect bites, kissing and sexual contact.
Vaccines, proper hand washing and medicines can help prevent infections.
There are four main kinds of germs:
Bacteria - one-celled germs that multiply quickly and
may release chemicals which can make you sick
Viruses - capsules that contain genetic material, and
use your own cells to multiply
Fungi - primitive plants, like mushrooms or mildew
Protozoa - one-celled animals that use other living things for
food and a place to live

How well you and your doctor communicate with each other is one of the most important parts of getting good health care. Being prepared can help make the most of your visit. Here are some things you can bring:
Lists of your concerns, any allergies and all the medicines, herbs, or vitamins you take
A description of symptoms - when they started, what makes them better
A trusted friend or family member
A way to take notes during your appointment
Make sure you understand your diagnosis and any treatments. Ask your health care provider to write down his or her instructions to you. If you still have trouble understanding, ask where you can go for more information.
Many disorders can affect our ability to speak and communicate. They range from saying sounds incorrectly to being completely unable to speak or understand speech. Causes include
Hearing disorders and deafness
Voice problems, such as dysphonia or those caused by cleft lip or palate
Speech problems like stuttering
Developmental disabilities
Learning disorders
Autism spectrum disorder
Brain injury
Stroke
Some speech and communication problems may be genetic. Often, no one knows the causes. By first grade, about 5 percent of children have noticeable speech disorders. Speech and language therapy can help.

Many Americans use medical treatments that are not part of mainstream medicine. When you are using these types of care, it may be called complementary, integrative, or alternative medicine.
Complementary medicine is used together with mainstream medical care. An example is using acupuncture to help with side effects of cancer treatment. When health care providers and facilities offer both types of care, it is called integrative medicine. Alternative medicine is used instead of mainstream medical care.
The claims that non-mainstream practitioners make can sound promising. However, researchers do not know how safe many of these treatments are or how well they work. Studies are underway to determine the safety and usefulness of many of these practices.
To minimize the health risks of a non-mainstream treatment
Discuss it with your doctor. It might have side effects or interact with other medicines.

Complex regional pain syndrome (CRPS) is a chronic pain condition. It causes intense pain, usually in the arms, hands, legs, or feet. It may happen after an injury, either to a nerve or to tissue in the affected area. Rest and time may only make it worse.
Symptoms in the affected area are
Dramatic changes in skin temperature, color, or texture
Intense burning pain
Extreme skin sensitivity
Swelling and stiffness in affected joints
Decreased ability to move the affected body part
The cause of CRPS is unknown. There is no specific diagnostic test. Your doctor will diagnose CRPS based on your signs and symptoms.
There is no cure. It can get worse over time, and may spread to other parts of the body. Occasionally it goes away, either temporarily or for good. Treatment focuses on relieving the pain, and can include medicines, physical therapy, and nerve blocks.

Your backbone, or spine, is made up of 26 bone discs called vertebrae. The vertebrae protect your spinal cord and allow you to stand and bend. A number of problems can change the structure of the spine or damage the vertebrae and surrounding tissue. They include Infections Injuries Tumors Conditions, such as ankylosing spondylitis and scoliosis Bone changes that come with age, such as spinal stenosis and herniated disks Spinal diseases often cause pain when bone changes put pressure on the spinal cord or nerves. They can also limit movement. Treatments differ by disease, but sometimes they include back braces and surgery.
Many people enjoy gambling, whether it's betting on a horse or playing poker on the Internet. Most people who gamble don't have a problem, but some lose control of their gambling. Signs of problem gambling include
Always thinking about gambling
Lying about gambling
Spending work or family time gambling
Feeling bad after you gamble, but not quitting
Gambling with money you need for other things
If you have concerns about your gambling, ask for help. Your health care provider can work with you to find the treatment that's best for you.

A concussion is a type of brain injury. It involves a short loss of normal brain function. It happens when a hit to the head or body causes your head and brain to move rapidly back and forth. This sudden movement can cause the brain to bounce around or twist in the skull, creating chemical changes in your brain. Sometimes it can also stretch and damage your brain cells.
Sometimes people call a concussion a "mild" brain injury. It is important to understand that while concussions may not be life-threatening, they can still be serious.
Concussions are a common type of sports injury. Other causes of concussions include blows to the head, bumping your head when you fall, being violently shaken, and car accidents.
Symptoms of a concussion may not start right away; they may start days or weeks after the injury. Symptoms may include a headache or neck pain. You may also have nausea, ringing in your ears, dizziness, or tiredness. You may feel dazed or not your normal self for several days or weeks after the injury. Consult your health care professional if any of your symptoms get worse, or if you have more serious symptoms such as
Convulsions or seizures
Drowsiness or inability to wake up
A headache that gets worse and does not go away
Weakness, numbness, or decreased coordination
Repeated vomiting or nausea
Confusion
Slurred speech
Loss of consciousness
To diagnose a concussion, your health care provider will do a physical exam and will ask about your injury. You will most likely have a neurological exam, which checks your vision, balance, coordination, and reflexes. Your health care provider may also evaluate your memory and thinking. In some cases, you may also have a scan of the brain, such as a CT Scan or an MRI. A scan can check for bleeding or inflammation in the brain, as well as skull fractures.
Most people recover fully after a concussion, but it can take some time. Rest is very important after a concussion because it helps the brain to heal. In the very beginning, you may need to limit physical activities or activities that involve a lot of concentration, such as studying, working on the computer, or playing video games. Doing these may cause concussion symptoms (such as headache or tiredness) to come back or get worse. Then when your health care provider says that it is ok, you can start to return to your normal activities slowly.

All kids misbehave some times. And some may have temporary behavior problems due to stress. For example, the birth of a sibling, a divorce, or a death in the family may cause a child to act out. Behavior disorders are more serious. They involve a pattern of hostile, aggressive, or disruptive behaviors for more than 6 months. The behavior is also not appropriate for the child's age.
Warning signs can include
Harming or threatening themselves, other people or pets
Damaging or destroying property
Lying or stealing
Not doing well in school, skipping school
Early smoking, drinking or drug use
Early sexual activity
Frequent tantrums and arguments
Consistent hostility toward authority figures
If you see signs of a problem, ask for help. Poor choices can become habits. Kids who have behavior problems are at higher risk for school failure, mental health problems, and even suicide. Classes or family therapy may help parents learn to set and enforce limits. Talk therapy and behavior therapy for your child can also help.
Genital warts are a sexually transmitted disease (STD) caused by the human papillomavirus (HPV). The warts are soft, moist, pink, or flesh-colored bumps. You can have one or many of these bumps. In women, the warts usually occur in or around the vagina, on the cervix or around the anus. In men, genital warts are less common but might occur on the tip of the penis.
You can get genital warts during oral, vaginal, or anal sex with an infected partner. Correct usage of latex condoms greatly reduces, but does not completely eliminate, the risk of catching or spreading HPV. HPV vaccines may help prevent some of the HPV infections that cause genital warts.
Your health care provider usually diagnoses genital warts by seeing them. The warts might disappear on their own. If not, your health care provider can treat or remove them. The virus stays in your body even after treatment, so warts can come back.

You've probably seen your chart at your doctor's office. In fact, you may have charts at several doctors' offices. If you've been in the hospital, you have a chart there, too. These charts are your medical records. They may be on paper or electronic. To keep track of all this information, it's a good idea to keep your own personal health record.
What kind of information would you put in a personal health record? You could start with
Your name, birth date, blood type, and emergency contact information
Date of last physical
Dates and results of tests and screenings
Major illnesses and surgeries, with dates
A list of your medicines and supplements, the dosages, and how long you've taken them
Any allergies
Any chronic diseases
Any history of illnesses in your family
The adrenal glands are small glands located on top of each kidney. They produce hormones that you can't live without, including sex hormones and cortisol. Cortisol helps you respond to stress and has many other important functions.
With adrenal gland disorders, your glands make too much or not enough hormones. In Cushing's syndrome, there's too much cortisol, while with Addison's disease, there is too little. Some people are born unable to make enough cortisol.
Causes of adrenal gland disorders include
Genetic mutations
Tumors including pheochromocytomas
Infections
A problem in another gland, such as the pituitary, which helps to regulate the adrenal gland
Certain medicines
Treatment depends on which problem you have. Surgery or medicines can treat many adrenal gland disorders.

A hernia happens when part of an internal organ or tissue bulges through a weak area of muscle. Most hernias are in the abdomen.
There are several types of hernias, including
Inguinal, in the groin. This is the the most common type.
Umbilical, around the belly button
Incisional, through a scar
Hiatal, a small opening in the diaphragm that allows the upper part of the stomach to move up into the chest.
Congenital diaphragmatic, a birth defect that needs surgery
Hernias are common. They can affect men, women, and children. A combination of muscle weakness and straining, such as with heavy lifting, might contribute. Some people are born with weak abdominal muscles and may be more likely to get a hernia.
Treatment is usually surgery to repair the opening in the muscle wall. Untreated hernias can cause pain and health problems.
A congenital heart defect is a problem with the structure of the heart. It is present at birth. Congenital heart defects are the most common type of birth defect. The defects can involve the walls of the heart, the valves of the heart, and the arteries and veins near the heart. They can disrupt the normal flow of blood through the heart. The blood flow can slow down, go in the wrong direction or to the wrong place, or be blocked completely.
Doctors use a physical exam and special heart tests to diagnose congenital heart defects. They often find severe defects during pregnancy or soon after birth. Signs and symptoms of severe defects in newborns include
Rapid breathing
Cyanosis - a bluish tint to the skin, lips, and fingernails
Fatigue
Poor blood circulation
Many congenital heart defects cause few or no signs and symptoms. They are often not diagnosed until children are older.
Many children with congenital heart defects don't need treatment, but others do. Treatment can include medicines, catheter procedures, surgery, and heart transplants. The treatment depends on the type of the defect, how severe it is, and a child's age, size, and general health.
NIH: National Heart, Lung, and Blood Institute
Heart failure is a condition in which the heart can't pump enough blood to meet the body's needs. Heart failure does not mean that your heart has stopped or is about to stop working. It means that your heart is not able to pump blood the way it should. It can affect one or both sides of the heart.
The weakening of the heart's pumping ability causes
Blood and fluid to back up into the lungs
The buildup of fluid in the feet, ankles and legs - called edema
Tiredness and shortness of breath
Common causes of heart failure are coronary artery disease, high blood pressure and diabetes. It is more common in people who are 65 years old or older, African Americans, people who are overweight, and people who have had a heart attack. Men have a higher rate of heart failure than women.
Your doctor will diagnose heart failure by doing a physical exam and heart tests. Treatment includes treating the underlying cause of your heart failure, medicines, and heart transplantation if other treatments fail.
NIH: National Heart, Lung, and Blood Institute
Conjunctivitis is the medical name for pink eye. It involves inflammation of the outer layer of the eye and inside of the eyelid. It can cause swelling, itching, burning, discharge, and redness. Causes include
Bacterial or viral infection
Allergies
Substances that cause irritation
Contact lens products, eye drops, or eye ointments
Pinkeye usually does not affect vision. Infectious pink eye can easily spread from one person to another. The infection will clear in most cases without medical care, but bacterial pinkeye needs treatment with antibiotic eye drops or ointment.
NIH: National Eye Institute
Connective tissue is the material inside your body that supports many of its parts. It is the "cellular glue" that gives your tissues their shape and helps keep them strong. It also helps some of your tissues do their work. Cartilage and fat are examples of connective tissue.
There are over 200 disorders that impact connective tissue. Some, like cellulitis, are the result of an infection. Injuries can cause connective tissue disorders, such as scars. Others, such as Ehlers-Danlos syndrome, Marfan syndrome, and osteogenesis imperfecta, are genetic. Still others, like scleroderma, have no known cause. Each disorder has its own symptoms and needs different treatment.
Constipation means that a person has three or fewer bowel movements in a week. The stool can be hard and dry. Sometimes it is painful to pass. At one time or another, almost
everyone gets constipated. In most cases, it lasts a short time and is not serious. There are many things you can do to prevent constipation. They include
Eating more fruits, vegetables and grains, which are high in fiber Drinking plenty of water and other liquids Getting enough exercise Taking time to have a bowel movement when you need to Using laxatives only if your doctor says you should Asking your doctor if medicines you take may cause constipation It's not important that you have a bowel movement every day. If your bowel habits change, however, check with your doctor. NIH: National Institute of Diabetes and Digestive and Kidney Diseases
A rash is an area of irritated or swollen skin. Many rashes are itchy, red, painful, and irritated. Some rashes can also lead to blisters or patches of raw skin. Rashes are a symptom of many different medical problems. Other causes include irritating substances and allergies. Certain genes can make people more likely to get rashes.
Contact dermatitis is a common type of rash. It causes redness, itching, and sometimes small bumps. You get the rash where you have touched an irritant, such as a chemical, or something you are allergic to, like poison ivy.
Some rashes develop right away. Others form over several days. Although most rashes clear up fairly quickly, others are long-lasting and need long-term treatment.
Because rashes can be caused by many different things, it's important to figure out what kind you have before you treat it. If it is a bad rash, if it does not go away, or if you have other symptoms, you should see your health care provider. Treatments may include moisturizers, lotions, baths, cortisone creams that relieve swelling, and antihistamines, which relieve itching.
Eye wear protects or corrects your vision. Examples are
Sunglasses
Safety goggles
Glasses (also called eyeglasses)
Contact lenses
If you need corrective lenses, you may be able to choose between contacts or glasses. Either usually requires a prescription. Almost anyone can wear glasses. Contact lenses require more careful handling.
Many jobs and some sports carry a risk of eye injury. Thousands of children and adults get eye injuries every year. Most are preventable with proper eye protection. Everyone is at risk for eye damage from the sun year-round. It's important to regularly use sunglasses that block out at least 99 percent of UV rays.
Birth control, also known as contraception, is designed to prevent pregnancy. Birth control methods may work in a number of different ways:
Preventing sperm from getting to the eggs. Types include condoms, diaphragms, cervical caps, and contraceptive sponges.
Keeping the woman's ovaries from releasing eggs that could be fertilized. Types include birth control pills, patches, shots, vaginal rings, and emergency contraceptive pills.
IUDs, devices which are implanted into the uterus. They can be kept in place for several years.
Sterilization, which permanently prevents a woman from getting pregnant or a man from being able to get a woman pregnant
Your choice of birth control should depend on several factors. These include your health, frequency of sexual activity, number of sexual partners and desire to have children in the future. Your health care provider can help you select the best form of birth control for you.
NIH: National Institute of Child Health and Human Development
A bruise is a mark on your skin caused by blood trapped under the surface. It happens when an injury crushes small blood vessels but does not break the skin. Those vessels break open and leak blood under the skin. Bruises are often painful and swollen. You can get skin, muscle and bone bruises. Bone bruises are the most serious. It can take months for a bruise to fade, but most last about two weeks. They start off a reddish color, and then turn bluish-purple and greenish-yellow before returning to normal. To reduce bruising, ice the injured area and elevate it above your heart. See your healthcare provider if you seem to bruise for no reason, or if the bruise appears to be infected.
Thalassemias are inherited blood disorders. If you have one, your body makes fewer healthy red blood cells and less hemoglobin. Hemoglobin is a protein that carries oxygen to the body. That leads to anemia. Thalassemias occur most often among people of Italian, Greek, Middle Eastern, Southern Asian, and African descent.
Thalassemias can be mild or severe. Some people have no symptoms or mild anemia. The most common severe type in the United States is called Cooley's anemia. It usually appears during the first two years of life. People with it may have severe anemia, slowed growth and delayed puberty, and problems with the spleen, liver, heart, or bones.
Doctors diagnose thalassemias using blood tests. Treatments include blood transfusions and treatment to remove excess iron from the body. If you have mild symptoms or no symptoms, you may not need treatment. In some severe cases, you may need a bone marrow transplant.

COPD (chronic obstructive pulmonary disease) makes it hard for you to breathe. The two main types are chronic bronchitis and emphysema. The main cause of COPD is long-term exposure to substances that irritate and damage the lungs. This is usually cigarette smoke. Air pollution, chemical fumes, or dust can also cause it.
At first, COPD may cause no symptoms or only mild symptoms. As the disease gets worse, symptoms usually become more severe. They include
A cough that produces a lot of mucus
Shortness of breath, especially with physical activity
Wheezing
Chest tightness
Doctors use lung function tests, imaging tests, and blood tests to diagnose COPD. There is no cure. Treatments may relieve symptoms. They include medicines, oxygen therapy, surgery, or a lung transplant. Quitting smoking is the most important step you can take to treat COPD.

Having a long-term, or chronic, illness can disrupt your life in many ways. You may often
be tired and in pain. Your illness might affect your appearance or your physical abilities
and independence. You may not be able to work, causing financial problems.
For children, chronic illnesses can be frightening, because they may not understand why
this is happening to them. These changes can cause stress, anxiety and anger. If they do, it is important to seek
help. A trained counselor can help you develop strategies to regain a feeling of control.
Support groups might help, too. You will find that you are not alone, and you may learn
some new tips on how to cope.
No matter how well you have prepared, you might feel dazed or numb after going through a disaster. You may also feel sad, helpless, or anxious. In spite of the tragedy, you might just feel happy to be alive.
It is not unusual to have bad memories or dreams. You may avoid places or people that remind you of the disaster. You might have trouble sleeping, eating, or paying attention. Many people have short tempers and get angry easily. These are all normal reactions to stress.
Sometimes the stress can be too much to handle alone. Some people have long-term problems after a disaster, including
Post-traumatic stress disorder
Depression
Self-blame
Suicidal thoughts
Alcohol or drug abuse
If your emotional reactions are getting in the way of your relationships, work, or other important activities, talk to a counselor or your doctor. Treatments are available.

Minerals are important for your body to stay healthy. Your body uses minerals for many different jobs, including keeping your bones, muscles, heart, and brain working properly. Minerals are also important for making enzymes and hormones.
There are two kinds of minerals: macrominerals and trace minerals. You need larger amounts of macrominerals. They include calcium, phosphorus, magnesium, sodium, potassium, chloride and sulfur. You only need small amounts of trace minerals. They include iron, manganese, copper, iodine, zinc, cobalt, fluoride and selenium.
Most people get the amount of minerals they need by eating a wide variety of foods. In some cases, your doctor may recommend a mineral supplement. People who have certain health problems or take some medicines may need to get less of one of the minerals. For example, people with chronic kidney disease need to limit foods that are high in potassium.
Wilson disease is a rare inherited disorder that prevents your body from getting rid of extra copper. You need a small amount of copper from food to stay healthy. Too much copper is poisonous.
Normally, your liver releases extra copper into bile, a digestive fluid. With Wilson disease, the copper builds up in your liver, and it releases the copper directly into your bloodstream. This can cause damage to your brain, kidneys, and eyes.
Wilson disease is present at birth, but symptoms usually start between ages 5 and 35. It first attacks the liver, the central nervous system or both. The most characteristic sign is a rusty brown ring around the cornea of the eye. A physical exam and laboratory tests can diagnose it.
Treatment is with drugs to remove the extra copper from your body. You need to take medicine and follow a low-copper diet for the rest of your life. Don't eat shellfish or liver, as these foods may contain high levels of copper. At the beginning of treatment, you'll also need to avoid chocolate, mushrooms, and nuts. Have your drinking water checked for copper content and don't take multivitamins that contain copper.
With early detection and proper treatment, you can enjoy good health.

Pulmonary hypertension (PH) is high blood pressure in the arteries to your lungs. It is a serious condition. If you have it, the blood vessels that carry blood from your heart to your lungs become hard and narrow. Your heart has to work harder to pump the blood through. Over time, your heart weakens and cannot do its job and you can develop heart failure.
Symptoms of PH include
Shortness of breath during routine activity, such as climbing two flights of stairs
Tiredness
Chest pain
A racing heartbeat
Pain on the upper right side of the abdomen
Decreased appetite
As PH worsens, you may find it hard to do any physical activities.
There are two main kinds of PH. One runs in families or appears for no known reason. The other kind is related to another condition, usually heart or lung disease.
There is no cure for PH. Treatments can control symptoms. They involve treating the heart or lung disease, medicines, oxygen, and sometimes lung transplantation.

Stem cells are cells with the potential to develop into many different types of cells in the body. They serve as a repair system for the body. There are two main types of stem cells: embryonic stem cells and adult stem cells.
Stem cells are different from other cells in the body in three ways:
They can divide and renew themselves over a long time
They are unspecialized, so they cannot do specific functions in the body
They have the potential to become specialized cells, such as muscle cells, blood cells, and brain cells
Doctors and scientists are excited about stem cells because they could help in many different areas of health and medical research. Studying stem cells may help explain how serious conditions such as birth defects and cancer come about. Stem cells may one day be used to make cells and tissues for therapy of many diseases. Examples include Parkinson's disease, Alzheimer's disease, spinal cord injury, heart disease, diabetes, and arthritis.

Carbohydrates are one of the main types of nutrients. They are the most important source of energy for your body. Your digestive system changes carbohydrates into glucose (blood sugar). Your body uses this sugar for energy for your cells, tissues and organs. It stores any extra sugar in your liver and muscles for when it is needed.
Carbohydrates are called simple or complex, depending on their chemical structure. Simple carbohydrates include sugars found naturally in foods such as fruits, vegetables, milk, and milk products. They also include sugars added during food processing and refining. Complex carbohydrates include whole grain breads and cereals, starchy vegetables and legumes. Many of the complex carbohydrates are good sources of fiber.
For a healthy diet, limit the amount of added sugar that you eat and choose whole grains over refined grains.
Your cornea is the outermost layer of your eye. It is clear and shaped like a dome. The cornea helps to shield the rest of the eye from germs, dust, and other harmful matter. It also helps your eye to focus. If you wear contact lenses, they float on top of your corneas.
Problems with the cornea include
Refractive errors
Allergies
Infections
Injuries
Dystrophies - conditions in which parts of the cornea lose clarity due to a buildup of cloudy material
Treatments of corneal disorders include medicines, corneal transplantation, and corneal laser surgery.

Corns and calluses are caused by pressure or friction on your skin. They often appear on feet where the bony parts of your feet rub against your shoes. Corns usually appear on the tops or sides of toes while calluses form on the soles of feet. Calluses also can appear on hands or other areas that are rubbed or pressed. Wearing shoes that fit better or using non-medicated pads may help. While bathing, gently rub the corn or callus with a washcloth or pumice stone to help reduce the size. To avoid infection, do not try to shave off the corn or callus. See your doctor, especially if you have diabetes or circulation problems. NIH: National Institute on Aging
Coronary artery disease (CAD) is the most common type of heart disease. It is the leading cause of death in the United States in both men and women.
CAD happens when the arteries that supply blood to heart muscle become hardened and narrowed. This is due to the buildup of cholesterol and other material, called plaque, on their inner walls. This buildup is called atherosclerosis. As it grows, less blood can flow through the arteries. As a result, the heart muscle can't get the blood or oxygen it needs. This can lead to chest pain (angina) or a heart attack. Most heart attacks happen when a blood clot suddenly cuts off the hearts' blood supply, causing permanent heart damage.
Over time, CAD can also weaken the heart muscle and contribute to heart failure and arrhythmias. Heart failure means the heart can't pump blood well to the rest of the body. Arrhythmias are changes in the normal beating rhythm of the heart.
NIH: National Heart, Lung, and Blood Institute
In coronary artery disease (CAD), the arteries that supply blood and oxygen to your heart muscle grow hardened and narrowed. You may try treatments such as lifestyle changes, medicines, and angioplasty, a procedure to open the arteries. If these treatments don't help, you may need coronary artery bypass surgery.
The surgery creates a new path for blood to flow to the heart. The surgeon takes a healthy piece of vein from the leg or artery from the chest or wrist. Then the surgeon attaches it to the coronary artery, just above and below the narrowed area or blockage. This allows blood to bypass (get around) the blockage. Sometimes people need more than one bypass.
The results of the surgery usually are excellent. Many people remain symptom-free for many years. You may need surgery again if blockages form in the grafted arteries or veins or in arteries that weren't blocked before. Lifestyle changes and medicines may help prevent arteries from becoming clogged again.

Coronaviruses are common viruses that most people get some time in their life. They are common throughout the world, and they can infect people and animals. Several different coronaviruses can infect people and make them sick. They usually cause mild to moderate upper-respiratory illness. But, some coronaviruses can cause severe illness.
Coronaviruses probably spread through the air by coughing or sneezing, or by close personal contact. If you get infected, symptoms may include
Runny nose
Cough
Sore throat
Fever
You may be able to reduce your risk of infection by washing your hands often with soap and water, not touching your eyes, nose, or mouth, and avoiding close contact with people who are sick. There is no vaccine to prevent coronavirus infection. There are no specific treatments. You can relieve symptoms with pain and fever medicines and rest.

You may have heard of anabolic steroids, which can have harmful effects. But there's another type of steroid - sometimes called a corticosteroid - that treats a variety of problems. These steroids are similar to hormones that your adrenal glands make to fight stress associated with illnesses and injuries. They reduce inflammation and affect the immune system.
You may need to take corticosteroids to treat
Arthritis
Asthma
Autoimmune diseases such as lupus and multiple sclerosis
Skin conditions such as eczema and rashes
Some kinds of cancer
Steroids are strong medicines, and they can have side effects, including weakened bones and cataracts. Because of this, you usually take them for as short a time as possible.
If you have stained, broken or uneven teeth, cosmetic dentistry can help. Cosmetic dentistry is different from orthodontic treatment, which can straighten your teeth with braces or other devices.
Cosmetic dental procedures include
Bleaching to make teeth whiter
Repairing chips or rough spots with fillings that match your teeth
Filling cavities with tooth-colored materials
Reshaping teeth that don't match the others
Closing gaps between teeth
Covering broken teeth with porcelain crowns
Surgeons can reshape the appearance of body parts through cosmetic surgery. Some of the most common body parts people want to improve through surgery include Breasts: Increase or reduce the size of breasts or reshape sagging breasts Ears: Reduce the size of large ears or set protruding ears back closer to the head Eyes: Correct drooping upper eyelids or remove puffy bags below the eyes Face: Remove facial wrinkles, creases or acne scars Hair: Fill in balding areas with one's own hair Nose: Change the shape of the nose Tummy: Flatten the abdomen
Cosmetics are products you apply to your body to clean it, make it more attractive, or change the way it looks. They include
Hair dyes
Makeup
Perfumes
Skin-care creams
Cosmetics that treat or prevent diseases are also drugs. Products such as dandruff shampoo, fluoride toothpaste, and antiperspirant deodorant are both cosmetics and drugs. A good way to tell if you're buying a cosmetic that is also a drug is to see if the first ingredient listed is an "active ingredient." The active ingredient is the chemical that makes the product effective. The manufacturer must have proof that it's safe for its intended use.
Cosmetics can cause allergic reactions. The first sign is often red and irritated skin. Fragrances and preservatives are the most common causes of skin problems.
To find out all the ingredients in a cosmetic you use, check the container. Manufacturers are required to list them. Labels such as "natural" and "hypoallergenic" have no official meaning. Companies can use them to mean whatever they want.

Cartilage is the tough but flexible tissue that covers the ends of your bones at a joint. It also gives shape and support to other parts of your body, such as your ears, nose and windpipe. Healthy cartilage helps you move by allowing your bones to glide over each other. It also protects bones by preventing them from rubbing against each other.
Injured, inflamed, or damaged cartilage can cause symptoms such as pain and limited movement. It can also lead to joint damage and deformity. Causes of cartilage problems include
Tears and injuries, such as sports injuries
Genetic factors
Other disorders, such as some types of arthritis
Osteoarthritis results from breakdown of cartilage.

Coughing is a reflex that keeps your throat and airways clear. Although it can be annoying, coughing helps your body heal or protect itself. Coughs can be either acute or chronic. Acute coughs begin suddenly and usually last no more than 2 to 3 weeks. Acute coughs are the kind you most often get with a cold, flu, or acute bronchitis. Chronic coughs last longer than 2 to 3 weeks. Causes of chronic cough include
Chronic bronchitis
Asthma
Allergies
COPD (chronic obstructive pulmonary disease)
GERD (gastroesophageal reflux disease)
Smoking
Throat disorders, such as croup in young children
Some medicines
Water can help ease your cough - whether you drink it or add it to the air with a steamy shower or vaporizer. If you have a cold or the flu, antihistamines may work better than non-prescription cough medicines. Children under four should not have cough medicine. For children over four, use caution and read labels carefully.
Sneezing, sore throat, a stuffy nose, coughing -- everyone knows the symptoms of the common cold. It is probably the most common illness. Every year, adults get about 2-3 colds, and children get even more.
What can you do for your cold or cough symptoms? Besides drinking lots of fluids and getting plenty of rest, you may decide to take medicines. There are lots of different cold and cough medicines, and they do different things.
Nasal decongestants - unclog a stuffy nose
Cough suppressants - quiet a cough
Expectorants - loosen mucus so you can cough it up
Antihistamines - stop runny noses and sneezing
Pain relievers - ease fever, headaches, and minor aches and pains
Before taking these medicines, read the labels carefully. Many cold and cough medicines contain the same active ingredients. For example, taking too much of certain pain relievers can lead to serious injury. Do not give cold or cough medicines to children under four, and don't give aspirin to children. Finally, antibiotics won't help a cold.

Viruses are capsules with genetic material inside. They are very tiny, much smaller than bacteria. Viruses cause familiar infectious diseases such as the common cold, flu and warts. They also cause severe illnesses such as HIV/AIDS, smallpox and hemorrhagic fevers. Viruses are like hijackers. They invade living, normal cells and use those cells to multiply and produce other viruses like themselves. This eventually kills the cells, which can make you sick. Viral infections are hard to treat because viruses live inside your body's cells. They are "protected" from medicines, which usually move through your bloodstream. Antibiotics do not work for viral infections. There are a few antiviral medicines available. Vaccines can help prevent you from getting many viral diseases.

When someone's blood flow or breathing stops, seconds count. Permanent brain damage or death can happen quickly. If you know how to perform cardiopulmonary resuscitation (CPR), you could save a life. CPR is an emergency procedure for a person whose heart has stopped or is no longer breathing. CPR can maintain circulation and breathing until emergency medical help arrives.
Even if you haven't had training, you can do "hands-only" CPR for a teen or adult whose heart has stopped beating ("hands-only" CPR isn't recommended for children). "Hands-only" CPR uses chest compressions to keep blood circulating until emergency help arrives. If you've had training, you can use chest compressions, clear the airway, and do rescue breathing. Rescue breathing helps get oxygen to the lungs for a person who has stopped breathing. To keep your skills up, you should repeat the training every two years.
Lice are parasitic insects that can be found on people's heads and bodies. They survive by feeding on human blood. Lice found on each area of the body are different from each other. The three types of lice that live on humans are head lice, body lice (also called clothes lice), and pubic lice ("crabs").
Symptoms of lice may include
Intense itching Rash Visible nits (lice eggs) or crawling lice Lice spread most commonly by close person-to-person contact. Dogs, cats, and other pets do not spread human lice. Lice move by crawling. They cannot hop or fly. If you get lice, both over-the-counter and prescription medicines are available for treatment. Centers for Disease Control and Prevention
Cocaine is a white powder. It can be snorted up the nose or mixed with water and injected with a needle. Cocaine can also be made into small white rocks, called crack. Crack is smoked in a small glass pipe.
Cocaine speeds up your whole body. You may feel full of energy, happy, and excited. But then your mood can change. You can become angry, nervous, and afraid that someone's out to get you. You might do things that make no sense. After the "high" of the cocaine wears off, you can "crash" and feel tired and sad for days. You also get a strong craving to take the drug again to try to feel better.
No matter how cocaine is taken, it is dangerous. Some of the most common serious problems include heart attack and stroke. You are also at risk for HIV/AIDS and hepatitis, from sharing needles or having unsafe sex. Cocaine is more dangerous when combined with other drugs or alcohol.
It is easy to lose control over cocaine use and become addicted. Then, even if you get treatment, it can be hard to stay off the drug. People who stopped using cocaine can still feel strong cravings for the drug, sometimes even years later.

Muscle cramps are sudden, involuntary contractions or spasms in one or more of your muscles. They often occur after exercise or at night, lasting a few seconds to several minutes. It is a very common muscle problem. Muscle cramps can be caused by nerves that malfunction. Sometimes this malfunction is due to a health problem, such as a spinal cord injury or a pinched nerve in the neck or back. Other causes are Straining or overusing a muscle Dehydration A lack of minerals in your diet or the depletion of minerals in your body Not enough blood getting to your muscles Cramps can be very painful. Stretching or gently massaging the muscle can relieve this pain.
Chances are you've bumped your head before. Often, the injury is minor because your skull is hard and it protects your brain. But other head injuries can be more severe, such as a skull fracture, concussion, or traumatic brain injury.
Head injuries can be open or closed. A closed injury does not break through the skull. With an open, or penetrating, injury, an object pierces the skull and enters the brain. Closed injuries are not always less severe than open injuries.
Some common causes of head injuries are falls, motor vehicle accidents, violence, and sports injuries.
It is important to know the warning signs of a moderate or severe head injury. Get help immediately if the injured person has
A headache that gets worse or does not go away
Repeated vomiting or nausea
Convulsions or seizures
An inability to wake up
Dilated (enlarged) pupil in one or both eyes
Slurred speech
Weakness or numbness in the arms or legs
Loss of coordination
Increased confusion, restlessness, or agitation
Doctors use a neurologic exam and imaging tests to make a diagnosis. Treatment depends on the type of injury and how severe it is.

Craniofacial is a medical term that relates to the bones of the skull and face. Craniofacial abnormalities are birth defects of the face or head. Some, like cleft lip and palate, are among the most common of all birth defects. Others are very rare. Most of them affect how a person's face or head looks. These conditions may also affect other parts of the body. Treatment depends on the type of problem. Plastic and reconstructive surgery may help the person's appearance.
Face injuries and disorders can cause pain and affect how you look. In severe cases, they can affect sight, speech, breathing and your ability to swallow. Broken bones, especially the bones of your nose, cheekbone and jaw, are common facial injuries.
Certain diseases also lead to facial disorders. For example, nerve diseases like trigeminal neuralgia or Bell's palsy sometimes cause facial pain, spasms and trouble with eye or facial movement. Birth defects can also affect the face. They can cause underdeveloped or unusually prominent facial features or a lack of facial expression. Cleft lip and palate are a common facial birth defect.

Creatinine is a waste product in your blood. It comes from protein in your diet and the normal breakdown of muscles of your body. Creatinine is removed from blood by the kidneys and then passes out of the body in your urine. If you have kidney disease, the level of creatinine in your blood increases.
Blood (serum) and urine tests can check your creatinine levels. The tests are done to check how well your kidneys are working.

Creutzfeldt-Jakob disease (CJD) is a rare, degenerative brain disorder. Symptoms usually start around age 60. Memory problems, behavior changes, vision problems, and poor muscle coordination progress quickly to dementia, coma, and death. Most patients die within a year.
The three main categories of CJD are
Sporadic CJD, which occurs for no known reason
Hereditary CJD, which runs in families
Acquired CJD, which occurs from contact with infected tissue, usually during a medical procedure
Cattle can get a disease related to CJD called bovine spongiform encephalopathy (BSE) or "mad cow disease." There is concern that people can get a variant of CJD from eating beef from an infected animal, but there is no direct proof to support this.

Sudden infant death syndrome (SIDS) is the sudden, unexplained death of an infant younger than one year old. Some people call SIDS "crib death" because many babies who die of SIDS are found in their cribs.
SIDS is the leading cause of death in children between one month and one year old. Most SIDS deaths occur when babies are between one month and four months old. Premature babies, boys, African Americans, and American Indian/Alaska Native infants have a higher risk of SIDS.
Although health care professionals don't know what causes SIDS, they do know ways to reduce the risk. These include
Placing your baby on his or her back to sleep, even for short naps. "Tummy time" is for when babies are awake and someone is watching
Having your baby sleep in your room for at least the first six months. Your baby should sleep close to you, but on a separate surface designed for infants, such as a crib or bassinet.
Using a firm sleep surface, such as a crib mattress covered with a fitted sheet
Keeping soft objects and loose bedding away from your baby's sleep area
Breastfeeding your baby
Making sure that your baby doesn't get too hot. Keep the room at a comfortable temperature for an adult.
Not smoking during pregnancy or allowing anyone to smoke near your baby

Critical care helps people with life-threatening injuries and illnesses. It might treat problems such as complications from surgery, accidents, infections, and severe breathing problems. It involves close, constant attention by a team of specially-trained health care providers. Critical care usually takes place in an intensive care unit (ICU) or trauma center.
Monitors, intravenous (IV) tubes, feeding tubes, catheters, breathing machines, and other equipment are common in critical care units. They can keep a person alive, but can also increase the risk of infection.
Many patients in critical care recover, but some die. Having advance directives in place is important. They help health care providers and family members make end-of-life decisions if you are not able to make them.
Crohn's disease causes inflammation of the digestive system. It is one of a group of diseases called inflammatory bowel disease. Crohn's can affect any area from the mouth to the anus. It often affects the lower part of the small intestine called the ileum.
The cause of Crohn's disease is unknown. It may be due to an abnormal reaction by the body's immune system. It also seems to run in some families. It most commonly starts between the ages of 13 and 30.
The most common symptoms are pain in the abdomen and diarrhea. Other symptoms include
Bleeding from the rectum
Weight loss
Fever
Your doctor will diagnose Crohn's disease with a physical exam, lab tests, imaging tests, and a colonoscopy.
Crohn's can cause complications, such as intestinal blockages, ulcers in the intestine, and problems getting enough nutrients. People with Crohn's can also have joint pain and skin problems. Children with the disease may have growth problems.
There is no cure for Crohn's. Treatment can help control symptoms, and may include medicines, nutrition supplements, and/or surgery. Some people have long periods of remission, when they are free of symptoms.

When you look at an object, you're using several muscles to move both eyes to focus on it. If you have a problem with the muscles, the eyes don't work properly.
There are many kinds of eye movement disorders. Two common ones are
Strabismus - a disorder in which the two eyes don't line up in the same direction. This results in "crossed eyes" or "walleye."
Nystagmus - fast, uncontrollable movements of the eyes, sometimes called "dancing eyes"
Some eye movement disorders are present at birth. Others develop over time and may be associated with other problems, such as injuries. Treatments include glasses, patches, eye muscle exercises, and surgery. There is no cure for some kinds of eye movement disorders, such as most kinds of nystagmus.
Croup is an inflammation of the vocal cords (larynx) and windpipe (trachea). It causes difficulty breathing, a barking cough, and a hoarse voice. The cause is usually a virus, often parainfluenza virus. Other causes include allergies and reflux.
Croup often starts out like a cold. But then the vocal cords and windpipe become swollen, causing the hoarseness and the cough. There may also be a fever and high-pitched noisy sounds when breathing. The symptoms are usually worse at night, and last for about three to five days.
Children between the ages of 6 months and 3 years have the highest risk of getting croup. They may also have more severe symptoms. Croup is more common in the fall and winter.
Most cases of viral croup are mild and can be treated at home. Rarely, croup can become serious and interfere with your child's breathing. If you are worried about your child's breathing, call your health care provider right away.
Mobility aids help you walk or move from place to place if you are disabled or have an injury. They include
Crutches
Canes
Walkers
Wheelchairs
Motorized scooters
You may need a walker or cane if you are at risk of falling. If you need to keep your body weight off your foot, ankle or knee, you may need crutches. You may need a wheelchair or a scooter if an injury or disease has left you unable to walk.
Choosing these devices takes time and research. You should be fitted for crutches, canes and walkers. If they fit, these devices give you support, but if they don't fit, they can be uncomfortable and unsafe.
If you have ever had athlete's foot or a yeast infection, you can blame a fungus. A fungus is a primitive organism. Mushrooms, mold and mildew are examples. Fungi live in air, in soil, on plants and in water. Some live in the human body. Only about half of all types of fungi are harmful.
Some fungi reproduce through tiny spores in the air. You can inhale the spores or they can land on you. As a result, fungal infections often start in the lungs or on the skin. You are more likely to get a fungal infection if you have a weakened immune system or take antibiotics.
Fungi can be difficult to kill. For skin and nail infections, you can apply medicine directly to the infected area. Oral antifungal medicines are also available for serious infections.

Cryptosporidiosis (crypto) is an illness caused by a parasite. The parasite lives in soil, food, and water. It may also be on surfaces that have been contaminated with feces (poop). You can become infected by swallowing the parasite, if it is in your food, drinking water, or water that you swim in. You can also get it by touching your mouth with contaminated hands.
The most common symptom of crypto is watery diarrhea. Other symptoms include
Dehydration
Weight loss
Stomach cramps or pain
Fever
Nausea
Vomiting
Contact your health care provider if you have watery diarrhea that lasts more than a few days. Most people with crypto get better without treatment within one to two weeks. But crypto can cause serious problems in people with weak immune systems, like those with HIV/AIDS.
To reduce your risk of crypto, wash your hands often, only drink water that you know is safe, and wash or peel fresh fruits and vegetables before eating.

Computed tomography (CT) is a type of imaging. It uses special x-ray equipment to make cross-sectional pictures of your body.
Doctors use CT scans to look for
Broken bones
Cancers
Blood clots
Signs of heart disease
Internal bleeding
During a CT scan, you lie still on a table. The table slowly passes through the center of a large X-ray machine. The test is painless. During some tests you receive a contrast dye, which makes parts of your body show up better in the image.

Your elbow joint is made up of bone, cartilage, ligaments and fluid. Muscles and tendons help the elbow joint move. When any of these structures is hurt or diseased, you have elbow problems. Many things can make your elbow hurt. A common cause is tendinitis, an inflammation or injury to the tendons that attach muscle to bone. Tendinitis of the elbow is a sports injury, often from playing tennis or golf. You may also get tendinitis from overuse of the elbow. Other causes of elbow pain include sprains, strains, fractures, dislocations, bursitis and arthritis. Treatment depends on the cause.
Cushing's syndrome is a hormonal disorder. The cause is long-term exposure to too much cortisol, a hormone that your adrenal gland makes. Sometimes, taking synthetic hormone medicine to treat an inflammatory disease leads to Cushing's. Some kinds of tumors produce a hormone that can cause your body to make too much cortisol.
Cushing's syndrome is rare. Some symptoms are
Upper body obesity
Thin arms and legs
Severe fatigue and muscle weakness
High blood pressure
High blood sugar
Easy bruising
Lab tests can show if you have it and find the cause. Your treatment will depend on why you have too much cortisol. If it is because you have been taking synthetic hormones, a lower dose may control your symptoms. If the cause is a tumor, surgery and other therapies may be needed.

Your skin is your body's largest organ. It covers and protects your body. Your skin
Holds body fluids in, preventing dehydration
Keeps harmful microbes out, preventing infections
Helps you feel things like heat, cold, and pain
Keeps your body temperature even
Makes vitamin D when the sun shines on it
Anything that irritates, clogs, or inflames your skin can cause symptoms such as redness, swelling, burning, and itching. Allergies, irritants, your genetic makeup, and certain diseases and immune system problems can cause rashes, hives, and other skin conditions. Many skin problems, such as acne, also affect your appearance.

Self-harm refers to a person's harming their own body on purpose. About 1 in 100 people hurts himself or herself in this way. More females hurt themselves than males. A person who self-harms usually does not mean to kill himself or herself. But they are at higher risk of attempting suicide if they do not get help.
Self-harm tends to begin in teen or early adult years. Some people may engage in self-harm a few times and then stop. Others engage in it more often and have trouble stopping.
Examples of self-harm include
Cutting yourself (such as using a razor blade, knife, or other sharp object to cut the skin)
Punching yourself or punching things (like a wall)
Burning yourself with cigarettes, matches, or candles
Pulling out your hair
Poking objects through body openings
Breaking your bones or bruising yourself
Many people cut themselves because it gives them a sense of relief. Some people use cutting as a means to cope with a problem. Some teens say that when they hurt themselves, they are trying to stop feeling lonely, angry, or hopeless.
It is possible to overcome the urge to hurt yourself. There are other ways to find relief and cope with your emotions. Counseling may help.

A stroke is a medical emergency. Strokes happen when blood flow to your brain stops. Within minutes, brain cells begin to die. There are two kinds of stroke. The more common kind, called ischemic stroke, is caused by a blood clot that blocks or plugs a blood vessel in the brain. The other kind, called hemorrhagic stroke, is caused by a blood vessel that breaks and bleeds into the brain. "Mini-strokes" or transient ischemic attacks (TIAs), occur when the blood supply to the brain is briefly interrupted.
Symptoms of stroke are
Sudden numbness or weakness of the face, arm or leg (especially on one side of the body)
Sudden confusion, trouble speaking or understanding speech
Sudden trouble seeing in one or both eyes
Sudden trouble walking, dizziness, loss of balance or coordination
Sudden severe headache with no known cause
If you have any of these symptoms, you must get to a hospital quickly to begin treatment. Acute stroke therapies try to stop a stroke while it is happening by quickly dissolving the blood clot or by stopping the bleeding. Post-stroke rehabilitation helps individuals overcome disabilities that result from stroke damage. Drug therapy with blood thinners is the most common treatment for stroke.

For most kids and teens, technology is an important part of their lives. They browse the Web for information, use social networking sites, text, and chat. But there can also be dangers, and it is important for parents to monitor their children's use and teach them how to be safe online: Never give out personal information, such as your full name, address, phone number, or school name Tell an adult if any communication (chat, text, e-mail message) makes you feel threatened or uncomfortable Never send sexually explicit photographs or messages On social networking sites, use privacy controls and only friend people that you know Of course, some of this advice is good for adults, too.
Most people feel sad or irritable from time to time. They may say they're in a bad mood. A mood disorder is different. It affects a person's everyday emotional state. Nearly one in ten people aged 18 and older have mood disorders. These include depression and bipolar disorder (also called manic depression).
Mood disorders can increase a person's risk for heart disease, diabetes, and other diseases. Treatments include medication, psychotherapy, or a combination of both. With treatment, most people with mood disorders can lead productive lives.
Cystic fibrosis (CF) is an inherited disease of the mucus and sweat glands. It affects mostly your lungs, pancreas, liver, intestines, sinuses, and sex organs. CF causes your mucus to be thick and sticky. The mucus clogs the lungs, causing breathing problems and making it easy for bacteria to grow. This can lead to repeated lung infections and lung damage.
The symptoms and severity of CF can vary. Some people have serious problems from birth. Others have a milder version of the disease that doesn't show up until they are teens or young adults. Sometimes you will have few symptoms, but later you may have more symptoms.
CF is diagnosed through various tests, such as gene, blood, and sweat tests. There is no cure for CF, but treatments have improved greatly in recent years. In the past, most deaths from CF were in children and teenagers. Today, with improved treatments, some people who have CF are living into their forties, fifties, or older. Treatments may include chest physical therapy, nutritional and respiratory therapies, medicines, and exercise.

A cyst is a fluid-filled sac. You may get simple kidney cysts as you age; they are usually harmless. There are also some diseases which cause kidney cysts. One type is polycystic kidney disease (PKD). It runs in families. In PKD, many cysts grow in the kidneys. This can enlarge the kidneys and make them work poorly. About half of people with the most common type of PKD end up with kidney failure. PKD also causes cysts in other parts of the body, such as the liver.
Often, there are no symptoms at first. Later, symptoms include
Pain in the back and lower sides
Headaches
Blood in the urine
Doctors diagnose PKD with imaging tests and family history. There is no cure. Treatments can help with symptoms and complications. They include medicines and lifestyle changes, and if there is kidney failure, dialysis or kidney transplants.
Acquired cystic kidney disease (ACKD) happens in people who have chronic kidney disease, especially if they are on dialysis. Unlike PKD, the kidneys are normal sized, and cysts do not form in other parts of the body. ACKD often has no symptoms. Usually, the cysts are harmless and do not need treatment. If they do cause complications, treatments include medicines, draining the cysts, or surgery.

Interstitial cystitis (IC) is a condition that causes discomfort or pain in the bladder and a need to urinate frequently and urgently. It is far more common in women than in men. The symptoms vary from person to person. Some people may have pain without urgency or frequency. Others have urgency and frequency without pain. Women's symptoms often get worse during their periods. They may also have pain with sexual intercourse.
The cause of IC isn't known. There is no one test to tell if you have it. Doctors often run tests to rule out other possible causes of symptoms. There is no cure for IC, but treatments can help most people feel better. They include
Distending, or inflating, the bladder
Bathing the inside of the bladder with a drug solution
Oral medicines
Electrical nerve stimulation
Physical therapy
Lifestyle changes
Bladder training
In rare cases, surgery

The pelvic floor is a group of muscles and other tissues that form a sling or hammock across the pelvis. In women, it holds the uterus, bladder, bowel, and other pelvic organs in place so that they can work properly. The pelvic floor can become weak or be injured. The main causes are pregnancy and childbirth. Other causes include being overweight, radiation treatment, surgery, and getting older.
Common symptoms include
Feeling heaviness, fullness, pulling, or aching in the vagina. It gets worse by the end of the day or during a bowel movement.
Seeing or feeling a "bulge" or "something coming out" of the vagina
Having a hard time starting to urinate or emptying the bladder completely
Having frequent urinary tract infections
Leaking urine when you cough, laugh, or exercise
Feeling an urgent or frequent need to urinate
Feeling pain while urinating
Leaking stool or having a hard time controlling gas
Being constipated
Having a hard time making it to the bathroom in time
Your health care provider diagnoses the problem with a physical exam, a pelvic exam, or special tests. Treatments include special pelvic muscle exercises called Kegel exercises. A mechanical support device called a pessary helps some women. Surgery and medicines are other treatments.

Cytomegalovirus (CMV) is a virus found around the world. It is related to the viruses that cause chickenpox and infectious mononucleosis (mono). Between 50 percent and 80 percent of adults in the United States have had a CMV infection by age 40. Once CMV is in a person's body, it stays there for life.
CMV is spread through close contact with body fluids. Most people with CMV don't get sick and don't know that they've been infected. But infection with the virus can be serious in babies and people with weak immune systems. If a woman gets CMV when she is pregnant, she can pass it on to her baby. Usually the babies do not have health problems. But some babies can develop lifelong disabilities.
A blood test can tell whether a person has ever been infected with CMV. Most people with CMV don't need treatment. If you have a weakened immune system, your doctor may prescribe antiviral medicine. Good hygiene, including proper hand washing, may help prevent infections.
