E-Cigarettes

E-cigarettes, or electronic cigarettes, are battery-operated smoking devices. They often look like cigarettes, but work differently. Using an e-cigarette is called vaping. The user puffs on the mouthpiece of a cartridge. This causes a vaporizer to heat the liquid inside the cartridge. The liquid contains nicotine, flavorings, and other chemicals. The heated liquid turns into the vapor that is inhaled. Some people think that e-cigarettes are safer than cigarettes, and that they can be used to help people quit smoking. But not much is known about the health risks of using them, or whether they do help people quit smoking. However we do know about some dangers of e-cigarettes: They contain nicotine, which is addictive They contain other potentially harmful chemicals There is a link between e-cigarette use and tobacco cigarette use in teens The liquid in e-cigarettes can cause nicotine poisoning if someone drinks, sniffs, or touches it NIH: National Institute on Drug Abuse

E. Coli Infections

E. coli is the name of a type of bacteria that lives in your intestines. Most types of E. coli are harmless. However, some types can make you sick and cause diarrhea. One type causes travelers' diarrhea. The worst type of E. coli causes bloody diarrhea, and can sometimes cause kidney failure and even death. These problems are most likely to occur in children and in adults with weak immune systems. You can get E. coli infections by eating foods containing the bacteria. Symptoms of infection include Nausea or vomiting Severe abdominal cramps Watery or very bloody diarrhea Fatigue Fever To help avoid food poisoning and prevent infection, handle food safely. Cook meat well, wash fruits and vegetables before eating or cooking them, and avoid unpasteurized milk and juices. You can also get the infection by swallowing water in a swimming pool contaminated with human waste. Most cases of E. coli infection get better without treatment in 5 to 10 days. NIH: National Institute of Allergy and Infectious Diseases

Ear Disorders

Your ear has three main parts: outer, middle and inner. You use all of them in hearing. Sound waves come in through your outer ear. They reach your middle ear, where they make your eardrum vibrate. The vibrations are transmitted through three tiny bones, called ossicles, in your middle ear. The vibrations travel to your inner ear, a snail-shaped organ. The inner ear makes the nerve impulses that are sent to the brain. Your brain recognizes them as sounds. The inner ear also controls balance. A variety of conditions may affect your hearing or balance: Ear infections are the most common illness in infants and young children. Tinnitus, a roaring in your ears, can be the result of loud noises, medicines or a variety of other causes. Meniere's disease may be the result of fluid problems in your inner ear; its symptoms include tinnitus and dizziness. Ear barotrauma is an injury to your ear because of changes in barometric (air) or water pressure. Some ear disorders can result in hearing disorders and deafness.

Ear Infections

Ear infections are the most common reason parents bring their child to a doctor. Three out of four children will have at least one ear infection by their third birthday. Adults can also get ear infections, but they are less common. The infection usually affects the middle ear and is called otitis media. The tubes inside the ears become clogged with fluid and mucus. This can affect hearing, because sound cannot get through all that fluid. If your child isn't old enough to say "My ear hurts," here are a few things to look for Tugging at ears Crying more than usual Fluid draining from the ear Trouble sleeping Balance difficulties Hearing problems Your health care provider will diagnose an ear infection by looking inside the ear with an instrument called an otoscope. Often, ear infections go away on their own. Your health care provider may recommend pain relievers. Severe infections and infections in young babies may require antibiotics. Children who get infections often may need surgery to place small tubes inside their ears. The tubes relieve pressure in the ears so that the child can hear again. NIH: National Institute on Deafness and Other Communication Disorders

Earthquakes

An earthquake happens when two blocks of the earth suddenly slip past one another. Earthquakes strike suddenly, violently, and without warning at any time of the day or night. If an earthquake occurs in a populated area, it may cause property damage, injuries, and even deaths. If you live in a coastal area, there is the possibility of a tsunami. Damage from earthquakes can also lead to floods or fires. Although there are no guarantees of safety during an earthquake, 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. Federal Emergency Management Agency

Eating Disorders

Eating disorders are serious behavior problems. They can include severe overeating or not consuming enough food to stay healthy. They also involve extreme concern about your shape or weight. Types of eating disorders include Anorexia nervosa, in which you become too thin, but you don't eat enough because you think you are fat Bulimia nervosa, which involves periods of overeating followed by purging, sometimes through self-induced vomiting or using laxatives Binge-eating, which is out-of-control eating Women are more likely than men to have eating disorders. They usually start in the teenage years and often occur along with depression, anxiety disorders, and substance abuse. Eating disorders can lead to heart and kidney problems and even death. Getting help early is important. Treatment involves monitoring, talk therapy, nutritional counseling, and sometimes medicines. NIH: National Institute of Mental Health

Ebola

Ebola hemorrhagic fever is caused by a virus. It is a severe and often fatal disease. It can affect humans and other primates. Researchers believe that the virus first spreads from an infected animal to a human. It can then spread from human to human through direct contact with a patient's blood or secretions. Symptoms of Ebola may appear anywhere from 2 to 21 days after exposure to the virus. Symptoms usually include Fever Headache Joint and muscle aches Weakness Diarrhea Vomiting Stomach pain Lack of appetite Other symptoms including rash, red eyes, and internal and external bleeding, may also occur. The early symptoms of Ebola are similar to other, more common, diseases. This makes it difficult to diagnose Ebola in someone who has been infected for only a few days. However, if a person has the early symptoms of Ebola and there is reason to suspect Ebola, the patient should be isolated. It is also important to notify public health professionals. Lab tests can confirm whether the patient has Ebola. There is no cure for Ebola. Treatment involves supportive care such as fluids, oxygen, and treatment of complications. Some people who get Ebola are able to recover, but many do not. Centers for Disease Control and Prevention

EBV Infections see Infectious Mononucleosis

Infectious mononucleosis, or "mono", is an infection usually caused by the Epstein-Barr virus. The virus spreads through saliva, which is why it's sometimes called "kissing disease." Mono occurs most often in teens and young adults. However, you can get it at any age. Symptoms of mono include Fever Sore throat Swollen lymph glands Sometimes you may also have a swollen spleen. Serious problems are rare. A blood test can show if you have mono. Most people get better in two to four weeks. However, you may feel tired for a few months afterward. Treatment focuses on helping symptoms and includes medicines for pain and fever, warm salt water gargles and plenty of rest and fluids.

Echocardiography see Ultrasound

Ultrasound is a type of imaging. It uses high-frequency sound waves to look at organs and structures inside the body. Health care professionals use it to view the heart, blood vessels, kidneys, liver, and other organs. During pregnancy, doctors use ultrasound to view the fetus. Unlike x-rays, ultrasound does not expose you to radiation. During an ultrasound test, you lie on a table. A special technician or doctor moves a device called a transducer over part of your body. The transducer sends out sound waves, which bounce off the tissues inside your body. The transducer also captures the waves that bounce back. The ultrasound machine creates images from the sound waves.

Ecstasy see Club Drugs

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. NIH: National Institute on Drug Abuse

Ectopic Pregnancy

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. Dept. of Health and Human Services Office on Women's Health

Eczema

Eczema is a term for several different types of skin swelling. Eczema is also called dermatitis. Most types cause dry, itchy skin and rashes on the face, inside the elbows and behind the knees, and on the hands and feet. Scratching the skin can cause it to turn red, and to swell and itch even more. Eczema is not contagious. The cause is not known. It is likely caused by both genetic and environmental factors. Eczema may get better or worse over time, but it is often a long-lasting disease. People who have it may also develop hay fever and asthma. The most common type of eczema is atopic dermatitis. It is most common in babies and children but adults can have it too. As children who have atopic dermatitis grow older, this problem may get better or go away. But sometimes the skin may stay dry and get irritated easily. Treatments may include medicines, skin creams, light therapy, and good skin care. You can prevent some types of eczema by avoiding Things that irritate your skin, such as certain soaps, fabrics, and lotions Stress Things you are allergic to, such as food, pollen, and animals NIH: National Institute of Arthritis and Musculoskeletal and Skin Diseases

Edema

Edema means swelling caused by fluid in your body's tissues. It usually occurs in the feet, ankles and legs, but it can involve your entire body. Causes of edema include Eating too much salt Sunburn Heart failure Kidney disease Liver problems from cirrhosis Pregnancy Problems with lymph nodes, especially after mastectomy Some medicines Standing or walking a lot when the weather is warm To keep swelling down, your health care provider may recommend keeping your legs raised when sitting, wearing support stockings, limiting how much salt you eat, or taking a medicine called a diuretic - also called a water pill.

Egg Allergy see Food Allergy

Food allergy is an abnormal response to a food triggered by your body's immune system. In adults, the foods that most often trigger allergic reactions include fish, shellfish, peanuts, and tree nuts, such as walnuts. Problem foods for children can include eggs, milk, peanuts, tree nuts, soy, and wheat. The allergic reaction may be mild. In rare cases it can cause a severe reaction called anaphylaxis. Symptoms of food allergy include Itching or swelling in your mouth Vomiting, diarrhea, or abdominal cramps and pain Hives or eczema Tightening of the throat and trouble breathing Drop in blood pressure Your health care provider may use a detailed history, elimination diet, and skin and blood tests to diagnose a food allergy. When you have food allergies, you must be prepared to treat an accidental exposure. Wear a medical alert bracelet or necklace, and carry an auto-injector device containing epinephrine (adrenaline). You can only prevent the symptoms of food allergy by avoiding the food. After you and your health care provider have identified the foods to which you are sensitive, you must remove them from your diet. NIH: National Institute of Allergy and Infectious Diseases

Egg Donation see Assisted Reproductive Technology

Assisted reproductive technology (ART) is used to treat infertility. It includes fertility treatments that handle both a woman's egg and a man's sperm. It works by removing eggs from a woman's body. The eggs are then mixed with sperm to make embryos. The embryos are then put back in the woman's body. In vitro fertilization (IVF) is the most common and effective type of ART. ART procedures sometimes use donor eggs, donor sperm, or previously frozen embryos. It may also involve a surrogate or gestational carrier. A surrogate is a woman who becomes pregnant with sperm from the male partner of the couple. A gestational carrier becomes pregnant with an egg from the female partner and the sperm from the male partner. The most common complication of ART is a multiple pregnancy. It can be prevented or minimized by limiting the number of embryos that are put into the woman's body.

Ehlers-Danlos Syndrome

Ehlers-Danlos syndrome (EDS) is a group of inherited disorders that weaken connective tissues. Connective tissues are proteins that support skin, bones, blood vessels, and other organs. EDS usually affects your skin, joints and blood vessel walls. Symptoms include Loose joints Fragile, small blood vessels Abnormal scar formation and wound healing Soft, velvety, stretchy skin that bruises easily There are several types of EDS. They can range from mild to life-threatening. About 1 in 5,000 people has EDS. There is no cure. Treatment involves managing symptoms, often with medicines and physical therapy. It also includes learning how to protect your joints and prevent injuries.

Ehrlichiosis see Tick Bites

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

Elbow Injuries and Disorders

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.

Elder Abuse

Many older people are victims of elder abuse. It is the mistreatment of an older person, usually by a caregiver. It can happen within the family. It can also happen in assisted living facilities or nursing homes. The mistreatment may be Physical, sexual, or emotional abuse Neglect or abandonment Financial abuse - stealing of money or belongings Possible signs of elder abuse include unexplained bruises, burns, and injuries. There may also be bed sores and poor hygiene. The person may become withdrawn, agitated, and depressed. There may be a sudden change in the person's financial situation. Elder abuse will not stop on its own. Someone else needs to step in and help. If you think that an older person is in urgent danger, call 9-1-1. Otherwise, contact adult protective services. NIH: National Institute on Aging

Electrical Injuries

When you come in direct contact with electricity, it can pass through your body and cause injuries. These electrical injuries can be external or internal. You may have one or both types. External injuries are skin burns. Internal injuries include damage to your organs, bones, muscles, and nerves. You could also have abnormal heart rhythms and cardiac arrest. How bad your injuries are depends on how strong the electric current was, what type of current it was, how it moved through your body, and how long you were exposed. Other factors include how healthy you are, and how quickly you get treatment. Causes of electrical injuries include Lightning strikes Faulty electrical appliances Work-related exposures Contact with household wiring or power lines Accidents in small children, when they bite or suck on electrical cords, or stick objects in outlets If you get an electrical injury, you should see a doctor. You may have internal damage and not realize it.

Electrolytes see Fluid and Electrolyte Balance

Electrolytes are minerals in your body that have an electric charge. They are in your blood, urine and body fluids. Maintaining the right balance of electrolytes helps your body's blood chemistry, muscle action and other processes. Sodium, calcium, potassium, chlorine, phosphate and magnesium are all electrolytes. You get them from the foods you eat and the fluids you drink. Levels of electrolytes in your body can become too low or too high. That can happen when the amount of water in your body changes, causing dehydration or overhydration. Causes include some medicines, vomiting, diarrhea, sweating or kidney problems. Problems most often occur with levels of sodium, potassium or calcium.

Electromagnetic Fields

Electric and magnetic fields (EMFs) are areas of energy that surround electrical devices. Everyday sources of EMFs include Power lines Electrical wiring Microwave ovens Computers Cell phones 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. NIH: National Institute of Environmental Health Sciences

Electronic Health Records see Personal Health Records

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

Emergency Medical Services

If you get very sick or badly hurt and need help right away, you should use emergency medical services. These services use specially trained people and specially equipped facilities. You may need care in the hospital emergency room (ER). Doctors and nurses there treat emergencies, such as heart attacks and injuries. For some emergencies, you need help where you are. Emergency medical technicians, or EMTs, do specific rescue jobs. They answer emergency calls and give basic medical care. Some EMTs are paramedics - they have training to do medical procedures on site. They usually take you to the ER for more care. If you or someone you know needs emergency care, go to your hospital's emergency room. If you think the problem is life threatening, call 9-1-1.

Emergency Preparedness see Disaster Preparation and Recovery

Preparing for a disaster can reduce the fear, anxiety and losses that disasters cause. A disaster can be a natural disaster, like a hurricane, tornado, flood or earthquake. It might also be man-made, like a bioterrorist attack or chemical spill. You should know the risks and danger signs of different types of disasters. You should also have a disaster plan. Be ready to evacuate your home, and know how to treat basic medical problems. Make sure you have the insurance you need, including special types, like flood insurance. No matter what kind of disaster you experience, it causes emotional distress. After a disaster, recovery can take time. Stay connected to your family and friends during this period. Federal Emergency Management Agency

EMF see Electromagnetic Fields

Electric and magnetic fields (EMFs) are areas of energy that surround electrical devices. Everyday sources of EMFs include Power lines Electrical wiring Microwave ovens Computers Cell phones Some people worry about EMF exposure and cancer.

Emotional Health see Mental Health

Mental health includes our emotional, psychological, and social well-being. It affects how we think, feel and act as we cope with life. It also helps determine how we handle stress, relate to others, and make choices. Mental health is important at every stage of life, from childhood and adolescence through adulthood. Mental illnesses are serious disorders which can affect your thinking, mood, and behavior. There are many causes of mental disorders. Your genes and family history may play a role. Your life experiences, such as stress or a history of abuse, may also matter. Biological factors can also be part of the cause. Mental disorders are common, but treatments are available.

Emphysema

Emphysema is a type of COPD involving damage to the air sacs (alveoli) in the lungs. As a result, your body does not get the oxygen it needs. Emphysema makes it hard to catch your breath. You may also have a chronic cough and have trouble breathing during exercise. The most common cause is cigarette smoking. If you smoke, quitting can help prevent you from getting the disease. If you already have emphysema, not smoking might keep it from getting worse. Treatment is based on whether your symptoms are mild, moderate or severe. Treatments include inhalers, oxygen, medications and sometimes surgery to relieve symptoms and prevent complications.

Employee Health see Occupational Health

Occupational health problems occur at work or because of the kind of work you do. These problems can include Cuts, broken bones, sprains, and strains Loss of limbs Repetitive motion disorders Hearing problems caused by exposure to noise Vision problems Illness caused by breathing, touching, or swallowing unsafe substances Illness caused by exposure to radiation Exposure to germs in health care settings Good job safety and prevention practices can reduce your risk of these problems. Try to stay fit, reduce stress, set up your work area properly, and use the right equipment and gear.

Encephalitis

Encephalitis is an inflammation of the brain. Usually the cause is a viral infection, but bacteria can also cause it. It can be mild or severe. Most cases are mild. You may have flu-like symptoms. With a mild case, you may just need rest, plenty of fluids, and a pain reliever. Severe cases need immediate treatment. Symptoms of severe cases include Severe headache Sudden fever Drowsiness Vomiting Confusion Seizures In babies, additional symptoms may include constant crying, poor feeding, body stiffness, and bulging in the soft spots of the skull. Severe cases may require a stay in the hospital. Treatments include oral and intravenous (IV) medicines to reduce inflammation and treat infection. Patients with breathing difficulties may need artificial respiration. Some people may need physical, speech, and occupational therapy once the illness is under control. NIH: National Institute of Neurological Disorders and Stroke

Encopresis see Bowel Incontinence

Bowel incontinence is the inability to control your bowels. When you feel the urge to have a bowel movement, you may not be able to hold it until you get to a toilet. Millions of Americans have this problem. It affects people of all ages - children and adults. It is more common in women and older adults. It is not a normal part of aging. Causes include Constipation Damage to muscles or nerves of the anus and rectum Diarrhea Pelvic support problems Treatments include changes in diet, medicines, bowel training, or surgery. NIH: National Institute of Diabetes and Digestive and Kidney Diseases

End of Life Care see Hospice Care

Hospice care is end-of-life care. A team of health care professionals and volunteers provides it. They give medical, psychological, and spiritual support. The goal of the care is to help people who are dying have peace, comfort, and dignity. The caregivers try to control pain and other symptoms so a person can remain as alert and comfortable as possible. Hospice programs also provide services to support a patient's family. Usually, a hospice patient is expected to live 6 months or less. Hospice care can take place At home At a hospice center In a hospital In a skilled nursing facility NIH: National Cancer Institute

End of Life Issues

Planning for the end of life can be difficult. But by deciding what end-of-life care best suits your needs when you are healthy, you can help those close to you make the right choices when the time comes. End-of-life planning usually includes making choices about the following: The goals of care (for example, whether to use certain medicines during the last days of life) Where you want to spend your final days Which treatments for end-of-life care you wish to receive What type of palliative care and hospice care you wish to receive Advance directives can help make your wishes clear to your family and health care providers.

End-Stage Renal Disease see Kidney Failure

Healthy kidneys clean your blood by removing excess fluid, minerals, and wastes. They also make hormones that keep your bones strong and your blood healthy. But if the kidneys are damaged, they don't work properly. Harmful wastes can build up in your body. Your blood pressure may rise. Your body may retain excess fluid and not make enough red blood cells. This is called kidney failure. If your kidneys fail, you need treatment to replace the work they normally do. The treatment options are dialysis or a kidney transplant. Each treatment has benefits and drawbacks. No matter which treatment you choose, you'll need to make some changes in your life, including how you eat and plan your activities. But with the help of healthcare providers, family, and friends, most people with kidney failure can lead full and active lives. NIH: National Institute of Diabetes and Digestive and Kidney Diseases

Endocarditis

Endocarditis, also called infective endocarditis (IE), is an inflammation of the inner lining of the heart. The most common type, bacterial endocarditis, occurs when germs enter your heart. These germs come through your bloodstream from another part of your body, often your mouth. Bacterial endocarditis can damage your heart valves. If untreated, it can be life-threatening. It is rare in healthy hearts. Risk factors include having An abnormal or damaged heart valve An artificial heart valve Congenital heart defects The signs and symptoms of IE can vary from person to person. They also can vary over time in the same person. Symptoms you might notice include fever, shortness of breath, fluid buildup in your arms or legs, tiny red spots on your skin, and weight loss. Your doctor will diagnose IE based on your risk factors, medical history, signs and symptoms, and lab and heart tests. Early treatment can help you avoid complications. Treatment usually involves high-dose antibiotics. If your heart valve is damaged, you may need surgery. If you're at risk for IE, brush and floss your teeth regularly, and have regular dental checkups. Germs from a gum infection can enter your bloodstream. If you are at high risk, your doctor might prescribe antibiotics before dental work and certain types of surgery. NIH: National Heart, Lung, and Blood Institute

Endocrine Diseases

Your endocrine system includes eight major glands throughout your body. These glands make hormones. Hormones are chemical messengers. They travel through your bloodstream to tissues or organs. Hormones work slowly and affect body processes from head to toe. These include Growth and development Metabolism - digestion, elimination, breathing, blood circulation and maintaining body temperature Sexual function Reproduction Mood If your hormone levels are too high or too low, you may have a hormone disorder. Hormone diseases also occur if your body does not respond to hormones the way it is supposed to. Stress, infection and changes in your blood's fluid and electrolyte balance can also influence hormone levels. In the United States, the most common endocrine disease is diabetes. There are many others. They are usually treated by controlling how much hormone your body makes. Hormone supplements can help if the problem is too little of a hormone.

Endometrial Cancer see Uterine Cancer

The uterus, or womb, is the place where a baby grows when a women is pregnant. There are different types of uterine cancer. The most common type starts in the endometrium, the lining of the uterus. This type is also called endometrial cancer. The symptoms of uterine cancer include Abnormal vaginal bleeding or discharge Trouble urinating Pelvic pain Pain during intercourse Uterine cancer usually happens after menopause. It is more common in women who are obese. You also have a higher risk if you took estrogen-only hormone replacement therapy (menopausal hormone therapy) for many years. Tests to find uterine cancer include a pelvic exam, imaging tests, and a biopsy. The most common treatment is a hysterectomy, which is surgery to remove the uterus. Sometimes the surgery also removes the ovaries and fallopian tubes. Other treatments include hormone therapy, radiation therapy, and chemotherapy. Some women get more than one type of treatment. NIH: National Cancer Institute

Endometriosis

The uterus, or womb, is the place where a baby grows when a woman is pregnant. Endometriosis is a disease in which tissue that normally grows inside the uterus grows outside the uterus. It can grow on the ovaries, fallopian tubes, bowels, or bladder. Rarely, it grows in other parts of the body. Symptoms include Pain, usually in the abdomen, lower back, or pelvic areas Infertility Heavy periods and bleeding between periods Painful menstrual cramps Some women have no symptoms at all. Having trouble getting pregnant may be the first sign. The cause of endometriosis is not known. Surgery, usually a laparoscopy, is currently the only way to be sure that you have endometriosis. Your health care provider will first take your medical history, do a pelvic exam, and maybe do imaging tests. There is no cure, but treatments help with pain and infertility. They include pain medicines, hormone treatments, and surgery. NIH: National Institute of Child Health and Human Development

Endoscopy

Endoscopy is a procedure that lets your doctor look inside your body. It uses an instrument called an endoscope, or scope for short. Scopes have a tiny camera attached to a long, thin tube. The doctor moves it through a body passageway or opening to see inside an organ. Sometimes scopes are used for surgery, such as for removing polyps from the colon. There are many different kinds of endoscopy. Here are the names of some of them and where they look. Arthroscopy: joints Bronchoscopy: lungs Colonoscopy and sigmoidoscopy: large intestine Cystoscopy and ureteroscopy: urinary system Laparoscopy: abdomen or pelvis Upper gastrointestinal endoscopy: esophagus and stomach

Enlarged Prostate (BPH)

The prostate is a gland in men. It helps make semen, the fluid that contains sperm. The prostate surrounds the tube that carries urine out of the body. As men age, their prostate grows bigger. If it gets too large, it can cause problems. An enlarged prostate is also called benign prostatic hyperplasia (BPH). Most men will get BPH as they get older. Symptoms often start after age 50. BPH is not cancer, and it does not seem to increase your chance of getting prostate cancer. But the early symptoms are the same. Check with your doctor if you have A frequent and urgent need to urinate, especially at night Trouble starting a urine stream or making more than a dribble A urine stream that is weak, slow, or stops and starts several times The feeling that you still have to go, even just after urinating Small amounts of blood in your urine Severe BPH can cause serious problems over time, such as urinary tract infections, and bladder or kidney damage. If it is found early, you are less likely to develop these problems. Tests for BPH include a digital rectal exam, blood and imaging tests, a urine flow study, and examination with a scope called a cystoscope. Treatments include watchful waiting, medicines, nonsurgical procedures, and surgery. NIH: National Institute of Diabetes and Digestive and Kidney Diseases

Enterocele see Hernia

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.

Enterovirus see Viral Infections

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. NIH: National Institute of Allergy and Infectious Diseases

Enuresis see Bedwetting

Many children wet the bed until they are 5 or even older. A child's bladder might be too small. Or the amount of urine produced overnight can be more than the bladder can hold. Some children sleep too deeply or take longer to learn bladder control. Stress can also be a factor. Children should not be punished for wetting the bed. They don't do it on purpose, and most outgrow it. Call the doctor if your child is 7 years old or older and wets the bed more than two or three times in a week. The doctor will look for and treat any other heath problems that could cause the bedwetting. Bedwetting alarms, bladder training, and medicines might help with the bedwetting.

Environmental Health

Our environment affects our health. If parts of the environment, like the air, water, or soil become polluted, it can lead to health problems. For example, asthma pollutants and chemicals in the air or in the home can trigger asthma attacks. Some environmental risks are a part of the natural world, like radon in the soil. Others are the result of human activities, like lead poisoning from paint, or exposure to asbestos or mercury from mining or industrial use. NIH: National Institute of Environmental Health Sciences

Environmental Tobacco Smoke see Secondhand Smoke

Secondhand smoke is a mixture of the smoke that comes from the burning end of a cigarette, cigar, or pipe, and the smoke breathed out by the smoker. It contains more than 7,000 chemicals. Hundreds of those chemicals are toxic and about 70 can cause cancer. Health effects of secondhand smoke include Ear infections in children More frequent and severe asthma attacks in children Heart disease and lung cancer in adults who have never smoked There is no safe amount of secondhand smoke. Even low levels of it can be harmful. The only way to fully protect nonsmokers from secondhand smoke is not to allow smoking indoors. Centers for Disease Control and Prevention

Eosinophilia see Eosinophilic Disorders

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.

Epilepsy

Epilepsy is a brain disorder that causes people to have recurring seizures. The seizures happen when clusters of nerve cells, or neurons, in the brain send out the wrong signals. People may have strange sensations and emotions or behave strangely. They may have violent muscle spasms or lose consciousness. Epilepsy has many possible causes, including illness, brain injury, and abnormal brain development. In many cases, the cause is unknown. Doctors use brain scans and other tests to diagnose epilepsy. It is important to start treatment right away. There is no cure for epilepsy, but medicines can control seizures for most people. When medicines are not working well, surgery or implanted devices such as vagus nerve stimulators may help. Special diets can help some children with epilepsy. NIH: National Institute of Neurological Disorders and Stroke

Epstein-Barr Virus Infections see Infectious Mononucleosis

Infectious mononucleosis, or "mono", is an infection usually caused by the Epstein-Barr virus. The virus spreads through saliva, which is why it's sometimes called "kissing disease." Mono occurs most often in teens and young adults. However, you can get it at any age. Symptoms of mono include Fever Sore throat Swollen lymph glands Sometimes you may also have a swollen spleen. Serious problems are rare. A blood test can show if you have mono. Most people get better in two to four weeks. However, you may feel tired for a few months afterward. Treatment focuses on helping symptoms and includes medicines for pain and fever, warm salt water gargles and plenty of rest and fluids.

Equipment Safety see Medical Device Safety

A medical device is any product used to diagnose, cure, or treat a condition, or to prevent disease. They range from small and simple, like a blood glucose meter, to large and complicated, like a ventilator. You might use one at home or at work, or you may need one in a hospital. To use medical devices safely Know how your device works. Keep instructions close by Understand and properly respond to device alarms Have a back-up plan and supplies in the event of an emergency Keep emergency numbers available and update them as needed Educate your family and caregivers about your device Food and Drug Administration

Erectile Dysfunction

Erectile dysfunction (ED) is a common type of male sexual dysfunction. It is when a man has trouble getting or keeping an erection. ED becomes more common as you get older. But it's not a natural part of aging. Some people have trouble speaking with their doctors about sex. But if you have ED, you should tell your doctor. ED can be a sign of health problems. It may mean your blood vessels are clogged. It may mean you have nerve damage from diabetes. If you don't see your doctor, these problems will go untreated. Your doctor can offer several new treatments for ED. For many men, the answer is as simple as taking a pill. Getting more exercise, losing weight, or stopping smoking may also help. NIH: National Institute of Diabetes and Digestive and Kidney Diseases

Ergonomics

Ergonomics looks at what kind of work you do, what tools you use and your whole job environment. The aim is to find the best fit between you and your job conditions. Examples of ergonomic changes to your work might include Adjusting the position of your computer keyboard to prevent carpal tunnel syndrome Being sure that the height of your desk chair allows your feet to rest flat on floor Learning the right way to lift heavy objects to prevent back injuries Using handle coatings or special gloves to suppress vibrations from power tools No matter what the job is, the goal is to make sure that you are safe, comfortable, and less prone to work-related injuries.

ERT see Hormone Replacement Therapy

Menopause is the time in a woman's life when her period stops. It is a normal part of aging. In the years before and during menopause, the levels of female hormones can go up and down. This can cause symptoms such as hot flashes and vaginal dryness. Some women take hormone replacement therapy (HRT), also called menopausal hormone therapy, to relieve these symptoms. HRT may also protect against osteoporosis. However, HRT also has risks. It can increase your risk of breast cancer, heart disease, and stroke. Certain types of HRT have a higher risk, and each woman's own risks can vary depending upon her health history and lifestyle. You and your health care provider need to discuss the risks and benefits for you. If you do decide to take HRT, it should be the lowest dose that helps and for the shortest time needed. Taking hormones should be re-evaluated every six months. NIH: National Heart, Lung, and Blood Institute

Erythema Infectiosum see Fifth Disease

Fifth disease is a viral infection caused by parvovirus B19. The virus only infects humans; it's not the same parvovirus that dogs and cats can get. Fifth disease mostly affects children. Symptoms can include a low fever, cold symptoms, and a headache. Then you get a red rash on your face. It looks like a "slapped cheek." The rash can spread to the arms, legs, and trunk. Adults who get it might also have joint pain and swelling. Fifth disease spreads easily, through saliva and mucus. You can get it when an infected person coughs or sneezes. Frequently washing your hands might help prevent getting the virus. Most people become immune to the virus after having it once. Fifth disease is usually mild and goes away on its own. However, it can be serious if you Are pregnant Are anemic Have cancer or a weak immune system Centers for Disease Control and Prevention

Erythroblastosis Fetalis see Rh Incompatibility

There are four major blood types: A, B, O, and AB. The types are based on substances on the surface of the blood cells. Another blood type is called Rh. Rh factor is a protein on red blood cells. Most people are Rh-positive; they have Rh factor. Rh-negative people don't have it. Rh factor is inherited though genes. When you're pregnant, blood from your baby can cross into your bloodstream, especially during delivery. If you're Rh-negative and your baby is Rh-positive, your body will react to the baby's blood as a foreign substance. It will create antibodies (proteins) against the baby's blood. These antibodies usually don't cause problems during a first pregnancy. But Rh incompatibility may cause problems in later pregnancies, if the baby is Rh-positive. This is because the antibodies stay in your body once they have formed. The antibodies can cross the placenta and attack the baby's red blood cells. The baby could get Rh disease, a serious condition that can cause a serious type of anemia. Blood tests can tell whether you have Rh factor and whether your body has made antibodies. Injections of a medicine called Rh immune globulin can keep your body from making Rh antibodies. It helps prevent the problems of Rh incompatibility. If treatment is needed for the baby, it can include supplements to help the body to make red blood cells and blood transfusions. NIH: National Heart, Lung, and Blood Institute

Esophageal Cancer

The esophagus is a hollow tube that carries food and liquids from your throat to your stomach. Early esophageal cancer usually does not cause symptoms. Later, you may have symptoms such as Painful or difficult swallowing Weight loss A hoarse voice or cough that doesn't go away You're at greater risk for getting esophageal cancer if you smoke, drink heavily, or have acid reflux. Your risk also goes up as you age Your doctor uses imaging tests and a biopsy to diagnose esophageal cancer. Treatments include surgery, radiation, and chemotherapy. You might also need nutritional support, since the cancer or treatment may make it hard to swallow. NIH: National Cancer Institute

Esophagus Disorders

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.

ESRD see Kidney Failure

Healthy kidneys clean your blood by removing excess fluid, minerals, and wastes. They also make hormones that keep your bones strong and your blood healthy. But if the kidneys are damaged, they don't work properly. Harmful wastes can build up in your body. Your blood pressure may rise. Your body may retain excess fluid and not make enough red blood cells. This is called kidney failure. If your kidneys fail, you need treatment to replace the work they normally do. The treatment options are dialysis or a kidney transplant. Each treatment has benefits and drawbacks. No matter which treatment you choose, you'll need to make some changes in your life, including how you eat and plan your activities. But with the help of healthcare providers, family, and friends, most people with kidney failure can lead full and active lives. NIH: National Institute of Diabetes and Digestive and Kidney Diseases

Essential Tremor see Tremor

Tremors are unintentional trembling or shaking movements in one or more parts of your body. Most tremors occur in the hands. You can also have arm, head, face, vocal cord, trunk, and leg tremors. Tremors are most common in middle-aged and older people, but anyone can have them. The cause of tremors is a problem in the parts of the brain that control muscles in the body or in specific parts of the body, such as the hands. They commonly occur in otherwise healthy people. They may also be caused by problems such as Parkinson's disease Dystonia Multiple sclerosis Stroke Traumatic brain injury Alcohol abuse and withdrawal Certain medicines Some forms are inherited and run in families. Others have no known cause. There is no cure for most tremors. Treatment to relieve them depends on their cause. In many cases, medicines and sometimes surgical procedures can reduce or stop tremors and improve muscle control. Tremors are not life threatening. However, they can be embarrassing and make it hard to perform daily tasks. NIH: National Institute of Neurological Disorders and Stroke

Estrogen Replacement Therapy see Hormone Replacement Therapy

Menopause is the time in a woman's life when her period stops. It is a normal part of aging. In the years before and during menopause, the levels of female hormones can go up and down.

Evaluating Health Information

Millions of consumers get health information from magazines, TV or the Internet. Some of the information is reliable and up to date; some is not. How can you tell the good from the bad? First, consider the source. If you use the Web, look for an "about us" page. Check to see who runs the site: Is it a branch of the government, a university, a health organization, a hospital or a business? Focus on quality. Does the site have an editorial board? Is the information reviewed before it is posted? Be skeptical. Things that sound too good to be true often are. You want current, unbiased information based on research. NIH: National Library of Medicine

Ewing's Sarcoma see Bone Cancer

Cancer that starts in a bone is uncommon. Cancer that has spread to the bone from another part of the body is more common. There are three types of bone cancer: Osteosarcoma - occurs most often between ages 10 and 19. It is more common in the knee and upper arm. Chondrosarcoma - starts in cartilage, usually after age 40 Ewing's sarcoma - occurs most often in children and teens under 19. It is more common in boys than girls. The most common symptom of bone cancer is pain. Other symptoms vary, depending on the location and size of the cancer. Surgery is often the main treatment for bone cancer. Other treatments may include amputation, chemotherapy, and radiation therapy. Because bone cancer can come back after treatment, regular follow-up visits are important. NIH: National Cancer Institute

Exercise and Physical Fitness

Regular physical activity is one of the most important things you can do for your health. It can help Control your weight Lower your risk of heart disease Lower your risk for type 2 diabetes and metabolic syndrome Lower your risk of some cancers Strengthen your bones and muscles Improve your mental health and mood Improve your ability to do daily activities and prevent falls, if you're an older adult Increase your chances of living longer Fitting regular exercise into your daily schedule may seem difficult at first. But even ten minutes at a time is fine. The key is to find the right exercise for you. It should be fun and should match your abilities. Centers for Disease Control and Prevention

Exercise for Children

Like adults, kids need exercise. Most children need at least an hour of physical activity every day. Regular exercise helps children Feel less stressed Feel better about themselves Feel more ready to learn in school Keep a healthy weight Build and keep healthy bones, muscles and joints Sleep better at night As kids spend more time watching TV, they spend less time running and playing. Parents should limit TV, video game and computer time. Parents can set a good example by being active themselves. Exercising together can be fun for everyone. Competitive sports can help kids stay fit. Walking or biking to school, dancing, bowling and yoga are some other ways for kids to get exercise.

Exercise for Seniors

Exercise and physical activity are good for just about everyone, including older adults. There are four main types and each type is different. Doing them all will give you more benefits. Endurance, or aerobic, activities increase your breathing and heart rate. Brisk walking or jogging, dancing, swimming, and biking are examples. Strength exercises make your muscles stronger. Lifting weights or using a resistance band can build strength. Balance exercises help prevent falls Flexibility exercises stretch your muscles and can help your body stay limber NIH: National Institute on Aging

Eye Cancer

Cancer of the eye is uncommon. It can affect the outer parts of the eye, such as the eyelid, which are made up of muscles, skin and nerves. If the cancer starts inside the eyeball it's called intraocular cancer. The most common intraocular cancers in adults are melanoma and lymphoma. The most common eye cancer in children is retinoblastoma, which starts in the cells of the retina. Cancer can also spread to the eye from other parts of the body. Treatment for eye cancer varies by the type and by how advanced it is. It may include surgery, radiation therapy, freezing or heat therapy, or laser therapy.

Eye Care

Your eyes are an important part of your health. Most people rely on their eyes to see and make sense of the world around them. But some eye diseases can lead to vision loss, so it is important to identify and treat eye diseases as early as possible. You should get your eyes checked as often as your health care provider recommends it, or if you have any new vision problems. And just as it is important to keep your body healthy, you also need to keep your eyes healthy. Eye Care Tips There are things you can do to help keep your eyes healthy and make sure you are seeing your best: Eat a healthy, balanced diet. Your diet should include plenty or fruits and vegetables, especially deep yellow and green leafy vegetables. Eating fish high in omega-3 fatty acids, such as salmon, tuna, and halibut can also help your eyes. Maintain a healthy weight. Being overweight or obese increases your risk of developing diabetes. Having diabetes puts you at higher risk of getting diabetic retinopathy or glaucoma. Get regular exercise. Exercise may help to prevent or control diabetes, high blood pressure, and high cholesterol. These diseases can lead to some eye or vision problems. So if you exercise regularly, you can lower your risk of getting these eye and vision problems. Wear sunglasses. Sun exposure can damage your eyes and raise your risk of cataracts and age-related macular degeneration. Protect your eyes by using sunglasses that block out 99 to 100 percent of both UV-A and UV-B radiation. Wear protective eye wear. To prevent eye injuries, you need eye protection when playing certain sports, working in jobs such as factory work and construction, and doing repairs or projects in your home. Avoid smoking. Smoking increases the risk of developing age-related eye diseases such as macular degeneration and cataracts and can damage the optic nerve. Know your family health history. Some eye diseases are inherited, so it is important to find out whether anyone in your family has had them. This can help you determine if you are at higher risk of developing an eye disease. Know your other risk factors. As you get older, you are at higher risk of developing age-related eye diseases and conditions. It is important to know you risk factors because you may be able to lower your risk by changing some behaviors. If you wear contacts, take steps to prevent eye infections. Wash your hands well before you put in or take out your contact lenses. Also follow the instructions on how to properly clean them, and replace them when needed. Give your eyes a rest. If you spend a lot of time using a computer, you can forget to blink your eyes and your eyes can get tired. To reduce eyestrain, try the 20-20-20 rule: Every 20 minutes, look away about 20 feet in front of you for 20 seconds. Eye Tests and Exams Everyone needs to have their eyesight tested to check for vision and eye problems. Children usually have vision screening in school or at their health care provider's office during a checkup. Adults may also get vision screenings during their checkups. But many adults need more than a vision screening. They need a comprehensive dilated eye exam. Getting comprehensive dilated eye exams is especially important because some eye diseases may not have warning signs. The exams are the only way to detect these diseases in their early stages, when they are easier to treat. The exam includes several tests: A visual field test to measure your side (peripheral) vision. A loss of peripheral vision may be a sign of glaucoma. A visual acuity test, where you read an eye chart about 20 feet away, to check on how well you see at various distances Tonometry, which measures your eye's interior pressure. It helps to detect glaucoma. Dilation, which involves getting eye drops that dilate (widen) your pupils. This allows more light to enter the eye. Your eye care provider examines your eyes using a special magnifying lens. This provides a clear view of important tissues at the back of your eye, including the retina, macula, and optic nerve. If you have a refractive error and are going to need glasses or contacts, then you will also have a refraction test. When you have this test, you look through a device that has lenses of different strengths to help your eye care professional figure out which lenses will give you the clearest vision. At what age you should start getting these exams and how often you need them depends on many factors. They include your age, race, and overall health. For example, if you are African American, you are at higher risk of glaucoma and you need to start getting the exams earlier. If you have diabetes, you should get an exam every year. Check with your health care provider about if and when you need these exams.

Eye Diseases

Some eye problems are minor and don't last long. But some can lead to a permanent loss of vision. Common eye problems include Refractive errors Cataracts - clouded lenses Optic nerve disorders, including glaucoma Retinal disorders - problems with the nerve layer at the back of the eye Macular degeneration - a disease that destroys sharp, central vision Diabetic eye problems Conjunctivitis - an infection also known as pinkeye Your best defense is to have regular checkups, because eye diseases do not always have symptoms. Early detection and treatment could prevent vision loss. See an eye care professional right away if you have a sudden change in vision, if everything looks dim, or if you see flashes of light. Other symptoms that need quick attention are pain, double vision, fluid coming from the eye, and inflammation. NIH: National Eye Institute

Eye Infections

Your eyes can get infections from bacteria, fungi, or viruses. Eye infections can occur in different parts of the eye and can affect just one eye or both. Two common eye infections are Conjunctivitis - also known as pinkeye. Conjunctivitis is often due to an infection. Children frequently get it, and it is very contagious. Stye - a bump on the eyelid that happens when bacteria from your skin get into the hair follicle of an eyelash. Symptoms of eye infections may include redness, itching, swelling, discharge, pain, or problems with vision. Treatment depends on the cause of the infection and may include compresses, eye drops, creams, or antibiotics.

Eye Injuries

The structure of your face helps protect your eyes from injury. Still, injuries can damage your eye, sometimes severely enough that you could lose your vision. Most eye injuries are preventable. If you play sports or work in certain jobs, you may need protection. The most common type of injury happens when something irritates the outer surface of your eye. Certain jobs such as industrial jobs or hobbies such as carpentry make this type of injury more likely. It's also more likely if you wear contact lenses. Chemicals or heat can burn your eyes. With chemicals, the pain may cause you to close your eyes. This traps the irritant next to the eye and may cause more damage. You should wash out your eye right away while you wait for medical help.

Eye Movement Disorders

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.

Eye Wear

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.

Eyelid Disorders

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.
