hypotension

You've probably heard that high blood pressure is a problem. Sometimes blood pressure that is too low can also cause problems.

Blood pressure is the force of your blood pushing against the walls of your arteries. Each time your heart beats, it pumps out blood into the arteries. Your blood pressure is highest when your heart beats, pumping the blood. This is called systolic pressure. When your heart is at rest, between beats, your blood pressure falls. This is the diastolic pressure. Your blood pressure reading uses these two numbers. Usually they're written one above or before the other, such as 120/80. If your blood pressure reading is 90/60 or lower, you have low blood pressure.

Some people have low blood pressure all the time. They have no symptoms and their low readings are normal for them. In other people, blood pressure drops below normal because of a medical condition or certain medicines. Some people may have symptoms of low blood pressure when standing up too quickly. Low blood pressure is a problem only if it causes dizziness, fainting or in extreme cases, shock.

Your autonomic nervous system is the part of your nervous system that controls involuntary actions, such as the beating of your heart and the widening or narrowing of your blood vessels. When something goes wrong in this system, it can cause serious problems, including:

• Blood pressure problems
• Heart problems
• Trouble with breathing and swallowing
• Erectile dysfunction in men

Autonomic nervous system disorders can occur alone or as the result of another disease, such as Parkinson's disease, alcoholism and diabetes. Problems can affect either part of the system, as in complex regional pain syndromes, or all of the system. Some types are temporary, but many worsen over time. When they affect your breathing or heart function, these disorders can be life-threatening.

Some autonomic nervous system disorders 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.

Your adrenal glands are just above your kidneys. The outside layer of these glands makes hormones that help your body respond to stress and regulate your blood pressure and water and salt balance. Addison disease happens if the adrenal glands don't make enough of these hormones.

A problem with your immune system usually causes Addison disease. The immune system mistakenly attacks your own tissues, damaging your adrenal glands. Other causes include infections and cancer.

Symptoms include:

• Weight loss
• Muscle weakness
• Fatigue that gets worse over time
• Low blood pressure
• Patchy or dark skin

Lab tests can confirm that you have Addison disease. If you don't treat it, it can be fatal. You will need to take hormone pills for the rest of your life. If you have Addison disease, you should carry an emergency ID. It should say that you have the disease, list your medicines and say how much you need in an emergency.

Atrial fibrillation, also known as AFib or AF, is one of the most common types of arrhythmias. Arrhythmias are problems with the rate or rhythm of your heartbeat. They can cause your heart to beat too slowly, too fast, or in an irregular way.

If you have AFib, your heart beats irregularly and sometimes much faster than normal. Also, your heart's upper and lower chambers do not work together as they should. When this happens, the lower chambers do not fill completely or pump enough blood to your lungs and body. This can cause symptoms such as dizziness, fatigue, and a pounding heartbeat.

AFib may happen in brief episodes, or it may be a permanent condition. It's very important to treat it, since AFib can put you at risk for stroke and other heart conditions.

AFib is most often caused by changes to the heart's tissue or the electrical signaling that helps the heartbeat. These changes can happen due to different conditions and factors, such as high blood pressure, coronary artery disease, congenital heart defects, infections, and aging. Sometimes the cause is unknown.

Anyone can develop AFib, but there are certain things that raise your risk for it:

• Aging. The risk of atrial fibrillation increases as you get older, especially when you are over age 65.
• Family history and genetics. AFib can run in families. So can heart disease, which raises your risk of AFib.
• Some lifestyle choices. Your risk is higher if you drink a lot of alcohol, use certain illegal drugs such as cocaine and methamphetamines, or smoke.
• Having certain health conditions, such as:
  • High blood pressure
  • Diabetes
  • Heart failure
  • Heart valve diseases
  • Obesity
  • Hyperthyroidism
  • Chronic kidney disease
  • COPD and other lung diseases
  • Sleep apnea
• Race. AFib is more common in people with European ancestry.
• Recent surgery. You may be at risk of atrial fibrillation in the early days and weeks after surgery on your heart, lungs, or esophagus.

Some people who have AFib don't have any symptoms and don't know they have it. If you do have symptoms, you may only notice them once in a while. Or you may have symptoms that are more frequent. And in some cases, the symptoms might be severe. If you have heart disease, you are more likely to notice your symptoms. And those symptoms could get worse if your heart disease gets worse.

The symptoms of AFib can include:

• Extreme fatigue, which is the most common symptom
• Heart palpitations (the feeling that your heart is skipping a beat, fluttering, pounding, or beating too hard or too fast)
• Trouble breathing, especially when lying down or when exercising
• Chest pain
• Dizziness or fainting
• Low blood pressure

If AFib is not treated, it can lead to serious health problems (complications) such as:

• Stroke
• Heart failure
• Blood clots
• Sudden cardiac arrest (SCA)
• Cognitive impairment and dementia

To help prevent these problems, it's important to contact your health care provider if you are having symptoms. If you do have AFib, the sooner you are diagnosed and treated, the better.

To find out if you have AFib, your provider:

• Will ask about your medical history, including your symptoms, lifestyle, and any other health conditions you may have
• Will ask about your family history, to find out if you have relatives who have or had AFib
• Will do a physical exam
• May order blood tests
• Will likely order heart tests, such as an electrocardiogram (also called an EKG or ECG) and echocardiogram
• May ask you to wear a heart monitor device that records your heart's electrical activity

The treatments for AFib may include:

• Blood thinner medicines that help prevent blood clots from forming.
• Medicines to control your heart's rhythm and rate.
• Following heart-healthy lifestyle changes, such as:
  • Following a heart-healthy eating plan that limits saturated fats, salt, and cholesterol. An example is the DASH eating plan.
  • Limiting or avoiding alcohol, because it can increase your heart rate.
  • Aiming for a healthy weight.
  • Getting regular physical activity.
  • Managing stress.
  • Quitting smoking.
• Procedures such as:
  • Electrical cardioversion, which restores your heart rhythm using low-energy shocks to your heart.
  • Catheter ablation, which scars the tissue that is causing the arrhythmia. The scar tissue blocks the abnormal heart signals.
• Surgeries such as:
  • Surgery to put in a pacemaker to help control the arrhythmia.
  • A Maze procedure, which creates scar tissue in a maze-like pattern in certain parts of the heart.
  • Left atrial appendage closure, a surgery on a small sac in the muscle wall of your left atrium (the upper left chamber of your heart). It helps prevent blood clots and can reduce your risk of stroke. This surgery is for people who are not able to take blood thinners.

There are steps you can take to help lower your risk of atrial fibrillation, such as:

• Making heart-healthy lifestyle changes:
  • Following a heart-healthy eating plan
  • Limiting or avoiding alcohol
  • Aiming for a healthy weight
  • Getting regular physical activity
  • Managing stress
  • Not smoking
• Avoiding illegal drugs, such as cocaine and methamphetamines
• Taking antiarrhythmic medicine (medicine to treat arrhythmia) if you are having heart surgery
• Treating any health conditions that could raise your risk of AFib

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.

Falls can be dangerous at any age. Babies and young children can get hurt falling off furniture or down the stairs. Older children may fall off playground equipment. For older adults, falls can be especially serious. They are at higher risk of falling. They are also more likely to fracture (break) a bone when they fall, especially if they have osteoporosis. A broken bone, especially when it is in a hip, may even lead to disability and a loss of independence for older adults.

Some common causes of falls include:

• Balance problems
• Some medicines, which can make you feel dizzy, confused, or slow
• Vision problems
• Alcohol, which can affect your balance and reflexes
• Muscle weakness, especially in your legs, which can make it harder for you to get up from a chair or keep your balance when walking on an uneven surface.
• Certain illnesses, such as low blood pressure, diabetes, and neuropathy
• Slow reflexes, which make it hard to keep your balance or move out of the way of a hazard
• Tripping or slipping due to loss of footing or traction

At any age, people can make changes to lower their risk of falling. It important to take care of your health, including getting regular eye exams. Regular exercise may lower your risk of falls by strengthening your muscles, improving your balance, and keeping your bones strong. And you can look for ways to make your house safer. For example, you can get rid of tripping hazards and make sure that you have rails on the stairs and in the bath. To reduce the chances of breaking a bone if you do fall, make sure that you get enough calcium and vitamin D.

Meningococcal disease is the name for any illness that is caused by Neisseria meningitidis bacteria (also called meningococcal bacteria). These illnesses are often severe and can sometimes be deadly. They include infections of the lining of the brain and spinal cord (meningitis) and in the bloodstream (sepsis). Vaccines can help prevent the disease.

Some people have Neisseria meningitidis, the bacteria that cause the disease, in the back of their nose and throat. They usually have the bacteria but don't get sick. This is called being a "carrier." But sometimes the bacteria can spread to other parts of the body and cause meningococcal disease.

The bacteria can spread from person to person through saliva (spit). It usually happens through close or lengthy contact with a person who has it. Close contact can include things like kissing and coughing.

You cannot catch the bacteria through casual contact with someone who has the disease. For example, you cannot get it by breathing air where that person has been.

Anyone can get meningococcal disease, but you are more likely to get it if someone you live with has it. You are also more likely to get it if you have direct contact with the saliva of someone who has it (like through kissing).

Also, certain groups of people are more likely to get the disease. They include:

• Children younger than 1 year old.
• Teens and young adults ages 16 through 23 years old.
• Adults 65 years and older.
• People with medical conditions that weaken their immune system, including those with HIV and certain rare immune system diseases.
• People who either don't have a spleen or have a spleen that does not function well.
• People who take complement inhibitor. These are immunotherapy medicines that are given to people with certain rare conditions.
• People who live in crowded settings, such as college dorms or military barracks.
• People who travel to areas where the disease is more common, such as certain parts of sub-Saharan Africa.

There are different types of meningococcal disease. The most common types are meningitis and septicemia. Both types are very serious and can be deadly in a matter of hours.

Meningococcal meningitis is a meningococcal infection of the lining of the brain and spinal cord. The most common symptoms include:

• Fever
• Headache
• Stiff neck

It can also cause symptoms such as:

• Nausea and vomiting
• Photophobia (your eyes being more sensitive to light)
• Confusion

It may be hard to notice these symptoms in newborns and babies. They can also have different symptoms. They may:

• Be slow or inactive
• Be irritable
• Vomit
• Feed poorly
• Have a bulging of the soft spot of their skull

Meningococcal septicemia is a meningococcal infection of the bloodstream. It's also called meningococcemia. When someone has this disease, the bacteria enter the bloodstream and multiply. This damages the walls of the blood vessels and causes bleeding into the skin and organs. The symptoms may include:

• Fever and chills
• Fatigue
• Vomiting
• Cold hands and feet
• Severe aches or pain in the muscles, joints, chest, or abdomen (belly)
• Rapid breathing
• Diarrhea
• A dark purple rash (in the later stages of the disease)

Because it is so serious, you need to seek immediate medical attention if you or your child develops the symptoms of meningococcal disease.

The signs and symptoms of meningococcal disease are often similar to those of other illnesses. This can make it hard to diagnose.

If your (or your child's) health care provider thinks that you or your child could have meningococcal disease, they will order tests that take samples of blood and/or cerebrospinal fluid (fluid near the spinal cord). They will send the samples to a lab for testing. The testing will include bacteria culture testing, which can identify the specific type of bacteria that is causing the infection. Knowing this can help the provider decide on the best treatment.

Certain antibiotics can treat meningococcal disease. It is important that treatment is started as soon as possible. So if the provider thinks you have meningococcal disease, they will give you antibiotics right away (before the test results come back).

People with serious disease may need additional treatments, such as:

• Breathing support
• Medicines to treat low blood pressure
• Surgery to remove dead tissue
• Wound care for parts of the body with damaged skin

Some people with meningococcal disease will have long-term health problems and disabilities. These may include:

• Loss of limb(s)
• Deafness
• Nervous system problems
• Brain damage

Even with treatment, 10 to 15 in 100 people will die from the disease.

The best way to prevent meningococcal disease is to get vaccinated. The U.S. Centers for Disease Control and Prevention (CDC) recommends meningococcal vaccination for:

• All preteens and teens
• Children at higher risk for meningococcal disease
• Adults at higher risk for meningococcal disease

If you are a close contact of a person with meningococcal disease, you will likely be given antibiotics to prevent you from getting sick. This is called "prophylaxis." Close contacts include people who are living together. They also include people who had direct contact with the saliva of a person who has the disease (such as from kissing).

Although it's rare, you can get meningococcal disease more than once.

A pulmonary embolism (PE) is a sudden blockage in a lung artery. It usually happens when a blood clot breaks loose and travels through the bloodstream to the lungs. PE is a serious condition that can cause:

• Permanent damage to the lungs
• Low oxygen levels in your blood
• Damage to other organs in your body from not getting enough oxygen

PE can be life-threatening, especially if a clot is large, or if there are many clots.

The cause is usually a blood clot that breaks loose and travels through the bloodstream to the lungs. The clot is usually a deep vein thrombosis (DVT), a clot in the leg. In rare cases, material such as air bubbles, clumps of fat, or parts of a tumor can block the lung artery and cause PE.

Anyone can get a pulmonary embolism (PE), but certain things can raise your risk of PE:

• Having surgery, especially joint replacement surgery.
• Certain medical conditions, including
• Cancers
• Heart diseases
• Lung diseases
• A broken hip or leg bone or other trauma
• Hormone-based medicines, such as birth control pills or hormone replacement therapy.
• Pregnancy and childbirth. The risk is highest for about six weeks after childbirth.
• Not moving for long periods, such as being on bed rest, having a cast, or taking a long plane flight.
• Age. Your risk increases as you get older, especially after age 40.
• Family history and genetics. Certain genetic changes that can increase your risk of blood clots and PE.
• Obesity.

Symptoms of PE include:

• Shortness of breath
• Rapid breathing
• Chest pain or discomfort, which usually gets worse when you cough or take a deep breath
• Increased heart rate
• Coughing up blood
• Very low blood pressure, lightheadedness, or fainting

Sometimes people with PE don't have any symptoms until they have serious complications, such as pulmonary hypertension (high blood pressure in the arteries to your lungs).

It can be difficult to diagnose PE. To find out if you have a PE, your health care provider will:

• Take your medical history, including asking about your symptoms and risk factors for PE
• Do a physical exam
• Likely order some tests, including various imaging and blood tests

If you have PE, you need medical treatment right away. The goal of treatment is to break up clots and help keep other clots from forming. Treatment options include medicines and procedures.

Medicines:

• Anticoagulants, or blood thinners, keep blood clots from getting larger and stop new clots from forming. You might get them as an injection, a pill, or through an I.V. (intravenous). They can cause bleeding, especially if you are taking other medicines that also thin your blood, such as aspirin.
• Thrombolytics are medicines to dissolve blood clots. You may get them if you have large clots that cause severe symptoms or other serious complications. Thrombolytics can cause sudden bleeding, so they are used if your PE is serious and may be life-threatening.

Procedures:

• Catheter-assisted thrombus removal uses a flexible tube to reach a blood clot in your lung. Your health care provider can insert a tool in the tube to break up the clot or to deliver medicine through the tube. Usually you will get medicine to put you to sleep for this procedure.
• A vena cava filter may be used in some people who cannot take blood thinners. Your health care provider inserts a filter inside a large vein called the vena cava. The filter catches blood clots before they travel to the lungs, which prevents pulmonary embolism. But the filter does not stop new blood clots from forming.

Preventing new blood clots can prevent PE. Prevention may include:

• Continuing to take blood thinners. It's also important to get regular checkups with your provider, to make sure that the dosage of your medicines is working to prevent blood clots but not causing bleeding.
• Heart-healthy lifestyle changes, such as heart-healthy eating, exercise, and, if you smoke, quitting smoking.
Using compression stockings to prevent deep vein thrombosis (DVT).
• Moving your legs when sitting for long periods of time (such as on long trips).
• Moving around as soon as possible after surgery or being confined to a bed.

Shock happens when not enough blood and oxygen can get to your organs and tissues. It causes very low blood pressure and may be life-threatening. It often happens along with a serious injury.

There are several kinds of shock. Hypovolemic shock happens when you lose a lot of blood or fluids. Causes include internal or external bleeding, dehydration, burns, and severe vomiting and/or diarrhea. Septic shock is caused by infections in the bloodstream. A severe allergic reaction can cause anaphylactic shock. An insect bite or sting might cause it. Cardiogenic shock happens when the heart cannot pump blood effectively. This may happen after a heart attack. Neurogenic shock is caused by damage to the nervous system.

Symptoms of shock include:

• Confusion or lack of alertness
• Loss of consciousness
• Sudden and ongoing rapid heartbeat
• Sweating
• Pale skin
• A weak pulse
• Rapid breathing
• Decreased or no urine output
• Cool hands and feet

Shock is a life-threatening medical emergency and it is important to get help right away. Treatment of shock depends on the cause.

Staphylococcus (staph) is a group of bacteria. There are more than 30 types. A type called Staphylococcus aureus causes most infections.

Staph bacteria can cause many different types of infections, including:

• Skin infections, which are the most common types of staph infections.
• Bacteremia, an infection of the bloodstream. This can lead to sepsis, a very serious immune response to infection.
• Bone infections.
• Endocarditis, an infection of the inner lining of the heart chambers and valves.
• Food poisoning.
• Pneumonia.
• Toxic shock syndrome (TSS), a life-threatening condition caused by toxins from certain types of bacteria.

Some people carry staph bacteria on their skin or in their noses, but they do not get an infection. But if they get a cut or wound, the bacteria can enter the body and cause an infection.

Staph bacteria can spread from person to person. They can also spread on objects, such as towels, clothing, door handles, athletic equipment, and remotes. If you have staph and do not handle food properly when you are preparing it, you can also spread staph to others.

Anyone can develop a staph infection, but certain people are more likely to get one, including those who:

• Have a chronic condition such as diabetes, cancer, vascular disease, eczema, and lung disease
• Have a weakened immune system, such as from HIV, medicines to prevent organ rejection, or chemotherapy
• Had surgery
• Are in the hospital
• Use a catheter, breathing tube, or feeding tube
• Have an implanted device, such as a pacemaker or artificial joint or heart valve
• Have burns, especially if they are deep or cover a large area of the body
• Are on dialysis
• Inject illegal drugs
• Do contact sports, since you may have skin-to-skin contact with others or share equipment

The symptoms of a staph infection depend on the type of infection:

• Skin infections can look like pimples or boils. They may be red, swollen, and painful. Sometimes there is pus or other drainage. They can turn into impetigo, which turns into a crust on the skin, or cellulitis, a swollen, red area of skin that feels hot.
• Bone infections can cause pain, swelling, warmth, and redness in the infected area. You may also have chills and a fever.
• Endocarditis causes some flu-like symptoms: fever, chills, and fatigue. It also causes symptoms such as rapid heartbeat, shortness of breath, and fluid buildup in your arms or legs.
• Food poisoning typically causes nausea and vomiting, diarrhea, and fever. If you lose too many fluids, you may also become dehydrated.
• Pneumonia symptoms include a high fever, chills, and cough that doesn't get better. You may also have chest pain and shortness of breath.
• Toxic shock syndrome (TSS) causes high fever, sudden low blood pressure, vomiting, diarrhea, and confusion. You may have a sunburn-like rash somewhere on your body. TSS can lead to organ failure.

Your health care provider will do a physical exam and ask about your symptoms. Often, providers can tell if you have a staph skin infection by looking at it. To check for other types of staph infections, providers may do a culture, with a skin scraping, tissue sample, stool sample, or throat or nasal swabs. There may be other tests, such as imaging tests, depending on the type of infection.

Treatment for staph infections is antibiotics. Depending on the type of infection, the antibiotics might be a cream, ointment, medicines (to swallow), or intravenous (IV) medicine. If you have an infected wound, your provider might drain it. Sometimes you may need surgery for bone infections.

Some staph infections, such as MRSA (methicillin-resistant Staphylococcus aureus), are resistant to many antibiotics. There are still certain antibiotics that can treat these infections.

Certain steps can help to prevent staph infections:

• Use good hygiene, including washing your hands often.
• Don't share towels, sheets, or clothing with someone who has a staph infection.
• It's best not to share athletic equipment. If you do need to share, make sure that it is properly cleaned and dried before you use it.
• Practice food safety, including not preparing food for others when you have a staph infection.
• If you have a cut or wound, keep it covered.
