pharyngitis

Your throat is a tube that carries food to your esophagus and air to your windpipe and larynx (also called the voice box). The technical name for the throat is pharynx.

You can have a sore throat for many reasons. Often, colds and flu cause sore throats. Other causes can include:

• Allergies
• Mononucleosis
• Smoking
• Strep throat
• Tonsillitis

Treatment depends on the cause. Sucking on lozenges, drinking lots of liquids, and gargling may ease the pain. Over-the-counter pain relievers can also help, but children should not take aspirin.

Tonsils are lumps of tissue at the back of the throat. There are two of them, one on each side. Along with the adenoids, tonsils are part of the lymphatic system. The lymphatic system clears away infection and keeps body fluids in balance. Tonsils and adenoids work by trapping the germs coming in through the mouth and nose.

Tonsillitis is an inflammation (swelling) of the tonsils. Sometimes along with tonsillitis, the adenoids are also swollen.

The cause of tonsillitis is usually a viral infection. Bacterial infections such as strep throat can also cause tonsillitis.

Tonsillitis is most common in children over age two. Almost every child in the United States gets it at least once. Tonsillitis caused by bacteria is more common in kids ages 5-15. Tonsillitis caused by a virus is more common in younger children.

Adults can get tonsillitis, but it is not very common.

Although tonsillitis is not contagious, the viruses and bacteria that cause it are contagious. Frequent handwashing can help prevent spreading or catching the infections.

The symptoms of tonsillitis include:

• A sore throat, which may be severe
• Red, swollen tonsils
• Trouble swallowing
• A white or yellow coating on the tonsils
• Swollen glands in the neck
• Fever
• Bad breath

You should call your health care provider if your child:

• Has a sore throat for more than two days
• Has trouble or pain when swallowing
• Feels very sick or very weak

You should get emergency care right away if your child:

• Has trouble breathing
• Starts drooling
• Has a lot of trouble swallowing

To diagnose tonsillitis, your child's health care provider will first ask you about your child's symptoms and medical history. The provider will look at your child's throat and neck, checking for things such as redness or white spots on the tonsils and swollen lymph nodes.

Your child will probably also have one or more tests to check for strep throat, since it can cause tonsillitis and it requires treatment. It could be a rapid strep test, a throat culture, or both. For both tests, the provider uses a cotton swab to collect a sample of fluids from your child's tonsils and the back of the throat. With the rapid strep test, testing is done in the office, and you get the results within minutes. The throat culture is done in a lab, and it usually takes a few days to get the results. The throat culture is a more reliable test. So sometimes if the rapid strep test is negative (meaning that it does not show any strep bacteria), the provider will also do a throat culture just to make sure that your child does not have strep.

Treatment for tonsillitis depends on the cause. If the cause is a virus, there is no medicine to treat it. If the cause is a bacterial infection, such as strep throat, your child will need to take antibiotics. It is important for your child to finish the antibiotics even if he or she feels better. If treatment stops too soon, some bacteria may survive and re-infect your child.

No matter what is causing the tonsillitis, there are some things you can do to help your child feel better. Make sure that your child:

• Gets a lot of rest
• Drinks plenty of fluids
• Tries eating soft foods if it hurts to swallow
• Tries eating warm liquids or cold foods like popsicles to soothe the throat
• Isn't around cigarette smoke or anything else that could irritate the throat
• Sleeps in a room with a humidifier
• Gargles with saltwater
• Sucks on a lozenge (but do not give them to children under four; they can choke on them)
• Takes an over-the-counter pain reliever such as acetaminophen. Children and teenagers should not take aspirin.

In some cases, your child may need a tonsillectomy.

A tonsillectomy is surgery to remove the tonsils. Your child might need it if he or she:

• Keeps getting tonsillitis
• Has bacterial tonsillitis that does not get better with antibiotics
• Has tonsils that are too big and are causing trouble breathing or swallowing

Your child usually gets the surgery and goes home later that day. Very young children and people who have complications may need to stay in the hospital overnight. It can take a week or two before your child completely recovers from the surgery.

Your throat is a tube that carries food to your esophagus and air to your windpipe and larynx. The technical name for your throat is the pharynx.

Throat problems are common. You've probably had a sore throat. The cause is usually a viral infection, but other causes include allergies, infection with strep bacteria or the leaking of stomach acids back up into the esophagus, called GERD.

Other problems that affect the throat include:

• Tonsillitis - inflammation of the tonsils
• Cancer
• Croup - inflammation, usually in small children, which causes a barking cough
• Laryngitis - swelling of the voice box, which can cause a hoarse voice or loss of voice

Most throat problems are minor and go away on their own. Treatments, when needed, depend on the problem.

Antibiotics are medicines that fight bacterial infections in people and animals. They work by killing the bacteria or by making it hard for the bacteria to grow and multiply.

Antibiotics can be taken in different ways:

• Orally (by mouth). This could be pills, capsules, or liquids.
• Topically. This might be a cream, spray, or ointment that you put on your skin. It could also be eye ointment, eye drops, or ear drops.
• Through an injection or intravenously (IV). This is usually for more serious infections.

Antibiotics only treat certain bacterial infections, such as strep throat, urinary tract infections, and E. coli.

You may not need to take antibiotics for some bacterial infections. For example, you might not need them for many sinus infections or some ear infections. Taking antibiotics when they're not needed won't help you, and they can have side effects. Your health care provider can decide the best treatment for you when you're sick. Don't ask your provider to prescribe an antibiotic for you.

Antibiotics do not work on viral infections. For example, you shouldn't take antibiotics for:

• Colds and runny noses, even if the mucus is thick, yellow, or green
• Most sore throats (except strep throat)
• Flu
• Most cases of bronchitis

The side effects of antibiotics range from minor to very severe. Some of the common side effects include:

• Rash
• Nausea
• Diarrhea
• Yeast infections

More serious side effects can include:

• C. diff infections, which cause diarrhea that can lead to severe colon damage and sometimes even death
• Severe and life-threatening allergic reactions
• Antibiotic resistance infections

Call your health care provider if you develop any side effects while taking your antibiotic.

You should only take antibiotics when they are needed because they can cause side effects and can contribute to Antibiotic resistance infections. Antibiotic resistance happens when the bacteria change and become able to resist the effects of an antibiotic. This means that the bacteria continue to grow.

When you take antibiotics, it is important that you take them responsibly:

• Always follow the directions carefully. Finish your medicine even if you feel better. If you stop taking them too soon, some bacteria may survive and re-infect you.
• Don't save your antibiotics for later.
• Don't share your antibiotic with others.
• Don't take antibiotics prescribed for someone else. This may delay the best treatment for you, make you even sicker, or cause side effects.

Birds, just like people, can get the flu. Another name for bird flu is avian influenza. The viruses that cause bird flu normally only infect birds, including chickens, other poultry, and wild birds such as ducks. But sometimes the viruses can infect other animals and, in rare cases, people.

A few types of these viruses have caused most of the infections in people. They are the H5N1, H7N9, and H5N6 viruses. These infections in people have mainly been in Asia, Africa, Europe, the Pacific, and the Near East. Although it's very rare, there have also been some infections in people in the United States.

The most common ways you can get bird flu are from:

• Touching your eyes, nose, or mouth after handling infected live or dead birds
• Touching surfaces or handling items contaminated by bird flu viruses and then touching your eyes, nose, or mouth
• Breathing in droplets or dust contaminated with the virus

It's also possible (but very rare) to get bird flu from:

• Another type of animal who has bird flu. Bird flu can also infect many other animals, including some dogs, cats, certain wild and zoo animals, and livestock such as cattle. These animals can then spread the flu to people.
• Another person.
• Eating poultry, eggs, and beef that were not properly handled and cooked.
• Drinking raw milk.

Certain people may be more likely to get bird flu, including:

• Poultry workers
• Animal handlers
• Wildlife biologists
• Disease control workers
• Research laboratory workers
• Veterinarians
• People who travel to countries where bird flu is present

Sometimes bird flu doesn't cause any symptoms. But if you do feel sick, your symptoms can range from mild to severe. Often, the symptoms are similar to the (seasonal) flu, such as:

• Fever (but not everyone has a fever)
• Cough
• Sore throat
• Runny or stuffy nose
• Muscle or body aches
• Fatigue
• Headaches
• Eye redness (conjunctivitis)
• Trouble breathing
• Diarrhea

People with severe illness from bird flu may have pneumonia and might need to be hospitalized.

Laboratory testing is used to diagnose bird flu. It's usually done with a nasal or throat swab. This testing is more accurate when the swab is collected during the first few days of illness.

For people who are severely ill, health care providers may do testing of a different sample, such as fluid taken during a bronchoalveolar lavage or other procedure.

Bird flu is treated with antiviral medicines. It's important to get them as soon as possible. The medicines may make your illness less severe.

You may also be given antiviral medicines if you were exposed to a person or animal who has the virus. This may help prevent you from getting sick.

There is currently no vaccine available to the public. The government has developed a virus that is similar to some H5N1 viruses. The virus could be used to produce a vaccine for people, if needed.

It's important to take precautions to prevent bird flu:

• If you have a job or pastime that puts you in contact with birds or other animals, make sure to use proper protective equipment.
• Otherwise try to avoid direct contact with wild birds and other animals.
• Wash your hands with soap and water after touching birds or other animals.
• Since it's possible to get bird flu through some foods, make sure to handle and cook your food safely and avoid raw milk.

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 ensuring 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

Cold and cough medicines can help relieve symptoms of a common cold. The symptoms of a cold can include a sore throat, stuffy or runny nose, sneezing, and coughing.

You don't usually need to treat a cold or the cough that it causes. You can't cure a cold, and antibiotics won't help you get better. But sometimes the symptoms can keep you awake or cause a lot of discomfort. In that case, cold and cough medicines can sometimes be helpful.

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 in your lungs 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 and follow the instructions carefully. Many cold and cough medicines contain the same active ingredients. For example, some of them include pain relievers. If you are taking these medicines and are also taking a separate pain reliever, you could be getting a dangerous amount of the pain reliever.

Do not give cold or cough medicines to children under two, and don't give aspirin to children.

If you decide that you don't want to take cold and cough medicines, there are other ways to feel better:

• Drink lots of fluids
• Get plenty of rest
• Use a cool mist humidifier
• Use saline nose drops or sprays
• Use nasal suctioning with a bulb syringe, which can be very helpful in children under a year old

The common cold is a mild infection of your upper respiratory tract (which includes your nose and throat). Colds are probably the most common illness. Adults have an average of 2-3 colds per year, and children have even more. Colds are more common in the winter and spring, but you can get them at any time.

More than 200 different viruses can cause a cold, but rhinoviruses are the most common type. The viruses that cause colds are very contagious. They can spread from person to person through the air and close personal contact. You can also get infected when you touch something that has the virus on it and then touch your eyes, mouth, or nose. For example, you could get a cold after you shake hands with someone who has a cold or touch a doorknob that has the germs on it, and then touch your face.

The symptoms of a common cold usually include:

• Sneezing
• Stuffy nose (congestion)
• Runny nose
• Sore throat
• Coughing
• Headache

The symptoms usually start a few days after you become infected with the virus. Some symptoms can last for 10-14 days.

There is no cure for the common cold. But there are treatments that can make you feel better while you wait for the cold to go away on its own:

• Getting lots of rest.
• Drinking plenty of fluids.
• Using a clean humidifier or cool mist vaporizer.
• Gargling with warm salt water.
• Using saline nose drops or sprays.
• Taking over-the-counter pain or cold and cough medicines. But you need to be careful with certain medicines:
  • Children and teens should not take aspirin.
  • Some cold and cough medicines contain ingredients that are not recommended for children. Talk with your child's health care provider before giving your child any cold and cough medicines.
  • Some cold and cough medicines contain pain relievers. If you also take a separate pain reliever with these medicines, you could be getting a dangerous amount of the pain reliever. Read the labels on the medicines and follow the instructions carefully. If you have questions, ask your provider or a pharmacist.

Antibiotics will not help with a cold. Antibiotics help with bacterial infections, not with viral infections such as colds.

Most people who have a cold will feel better after a week or two. However, some people who get a cold may develop other illnesses, such as bronchitis or pneumonia. This is more common in people with weakened immune systems, asthma, or other respiratory conditions. Contact your provider if you or your child have symptoms that concern you, such as:

• Trouble breathing or fast breathing
• Dehydration
• Fever that lasts longer than 4 days
• Symptoms that last more than 10 days without improvement
• Symptoms, such as fever or cough, that improve but then return or worsen
• Worsening of chronic medical conditions

There is no vaccine to protect against the common cold. But you may be able to reduce your risk of getting or spreading a cold by:

• Washing your hands often with soap and water for at least 20 seconds.
• Avoiding touching your face, nose, or mouth with unwashed hands.
• Avoiding close contact, such as kissing, shaking hands, and sharing cups and eating utensils, with others if you are sick or they are sick.
• Cleaning and disinfecting surfaces that you frequently touch.
• Covering coughs and sneezes with a tissue. Then throw away the tissue and wash your hands.
• Staying home when sick.

Diphtheria is a serious bacterial infection. You can catch it from a person who has the infection and coughs or sneezes. You can also get infected by coming in contact with an object, such as a toy, that has bacteria on it.

Diphtheria usually affects the nose and throat. Symptoms include:

• Sore throat
• Swollen glands in the neck
• Fever
• Weakness

Your doctor will diagnose it based on your signs and symptoms and a lab test. Getting treatment for diphtheria quickly is important. If your doctor suspects that you have it, you'll start treatment before the lab tests come back. Treatment is with antibiotics.

The diphtheria, pertussis, and tetanus vaccine can prevent diphtheria, but its protection does not last forever. Children need another dose, or booster, at about age 12. Then, as adults, they should get a booster every 10 years. Diphtheria is very rare in the United States because of the vaccine.

Eating disorders are serious mental health disorders. They involve severe problems with your thoughts about food and your eating behaviors. You may eat much less or much more than you need.

Eating disorders are medical conditions; they are not a lifestyle choice. They affect your body's ability to get proper nutrition. This can lead to health issues, such as heart and kidney problems, or sometimes even death. But there are treatments that can help.

Common types of eating disorders include:

• Binge-eating, which is out-of-control eating. People with binge-eating disorder keep eating even after they are full. They often eat until they feel very uncomfortable. Afterward, they usually have feelings of guilt, shame, and distress. Eating too much too often can lead to weight gain and obesity. Binge-eating disorder is the most common eating disorder in the U.S.
• Bulimia nervosa. People with bulimia nervosa also have periods of binge-eating. But afterwards, they purge, by making themselves throw up or using laxatives. They may also over-exercise or fast. People with bulimia nervosa may be slightly underweight, normal weight, or overweight.
• Anorexia nervosa. People with anorexia nervosa avoid food, severely restrict food, or eat very small quantities of only certain foods. They may see themselves as overweight, even when they are dangerously underweight. Anorexia nervosa is the least common of the three eating disorders, but it is often the most serious. It has the highest death rate of any mental disorder.

The exact cause of eating disorders is unknown. Researchers believe that eating disorders are caused by a complex interaction of factors. These include genetic, biological, behavioral, psychological, and social factors.

Anyone can develop an eating disorder, but they are more common in women. Eating disorders frequently appear during the teen years or young adulthood. But people can also develop them during childhood or later in life.

The symptoms of eating disorders vary, depending on the disorder:

The symptoms of binge-eating include:

• Eating unusually large amounts of food in a specific amount of time, such as a 2-hour period
• Eating even when you're full or not hungry
• Eating fast during binge episodes
• Eating until you're uncomfortably full
• Eating alone or in secret to avoid embarrassment
• Feeling distressed, ashamed, or guilty about your eating
• Frequently dieting, possibly without weight loss

The symptoms of bulimia nervosa include the same symptoms as binge-eating, plus trying to get rid of the food or weight after binging by:

• Purging, making yourself throw up or using laxatives or enemas to speed up the movement of food through your body
• Doing intensive and excessive exercise
• Fasting

Over time, bulimia nervosa can cause health problems such as:

• Chronically inflamed and sore throat
• Swollen salivary glands in the neck and jaw area
• Worn tooth enamel and increasingly sensitive and decaying teeth. This is caused by the exposure to stomach acid every time you throw up.
• GERD (acid reflux) and other gastrointestinal problems
• Severe dehydration from purging
• Electrolyte imbalance, which could be too low or too high levels of sodium, calcium, potassium and other minerals. This can lead to a stroke or heart attack.

The symptoms of anorexia nervosa include:

• Eating very little, to the point of starving yourself
• Intensive and excessive exercise
• Extreme thinness
• Intense fear of gaining weight
• Distorted body image - seeing yourself as overweight even when you are severely underweight

Over time, anorexia nervosa can cause health problems such as:

• Thinning of the bones (osteopenia or osteoporosis)
• Mild anemia
• Muscle wasting and weakness
• Thin, brittle hair and nails
• Dry, blotchy, or yellowish skin
• Growth of fine hair all over the body
• Severe constipation
• Low blood pressure
• Slowed breathing and pulse
• Feeling cold all the time because of a drop in internal body temperature
• Feeling faint, dizzy, or weak
• Feeling tired all the time
• Infertility
• Damage to the structure and function of the heart
• Brain damage
• Multiorgan failure

Anorexia nervosa can be fatal. Some people with this disorder die of complications from starvation, and others die of suicide.

Some people with eating disorders may also have other mental disorders (such as depression or anxiety) or problems with substance use.

Because eating disorders can be so serious, it is important to seek help if you or a loved one thinks that you might have a problem. Your health care provider may use many tools to make a diagnosis:

• A medical history, which includes asking about your symptoms. It is important to be honest about your eating and exercise behaviors so your provider can help you.
• A physical exam
• Blood or urine tests to rule out other possible causes of your symptoms
• Other tests to see whether you have any other health problems caused by the eating disorder. These can include kidney function tests and an electrocardiogram (EKG or ECG).

Treatment plans for eating disorders are tailored to individual needs. You will likely have a team of providers helping you, including doctors, nutritionists, nurses, and therapists. The treatments may include:

• Individual, group, and/or family psychotherapy. Individual therapy may include cognitive behavioral approaches, which help you to identify and change negative and unhelpful thoughts. It also helps you build coping skills and change behavioral patterns.
• Medical care and monitoring, including care for the complications that eating disorders can cause
• Nutrition counseling. Doctors, nurses, and counselors will help you eat healthy to reach and maintain a healthy weight.
• Medicines, such as antidepressants, antipsychotics, or mood stabilizers, may help treat some eating disorders. The medicines can also help with the depression and anxiety symptoms that often go along with eating disorders.

Some people with serious eating disorders may need to be in a hospital or in a residential treatment program. Residential treatment programs combine housing and treatment services.
