Diarrhea



Diarrhea is when you pass loose or watery stool.

Considerations

In some people, diarrhea is mild and goes away in a few days. In other people, it may last longer.

Diarrhea can make you feel weak and dehydrated.

Diarrhea inbabies and children can be serious. It needs to be treated differently than you would treat diarrhea in adults.

Talk with your health care provider if your child has diarrhea. There can be a lot to know. Your provider can help you learn how to recognize and treat diarrhea in babies and in children.

Causes of Diarrhea

The most common cause of diarrhea is the stomach flu (viral gastroenteritis). This mild viral infection most often goes away on its own within a few days.

Eating or drinking food or water that contains certain types of bacteria or parasites can also lead to diarrhea. This problem may be called food poisoning.

Certain medicines may also cause diarrhea, including:

Some antibiotics

Chemotherapy drugs for cancer

Laxatives containing magnesium

Diarrhea may also be caused by medical disorders, such as:

Celiac disease

Inflammatory bowel diseases (Crohn disease and ulcerative colitis)

Irritable bowel syndrome (IBS)

Lactose intolerance (which causes problems after drinking milk and eating other dairy products)

Malabsorption syndromes

Less common causes of diarrhea include:

Carcinoid syndrome

Disorders of the nerves that supply the intestines

Removal of part of the stomach (gastrectomy) or small intestine

Radiation therapy

People who travel to developing countries can get diarrhea from unclean water or food that has not been handled safely. Plan ahead by learning the risks and treatment for traveler’s diarrhea before your trip.

Home Care For Diarrhea

Most times, you can treat diarrhea at home. You will need to learn:

To drink plenty of fluids to prevent dehydration (when your body does not have the proper amount of water and fluids)

Which foods you should or should not eat

What to do if you are breastfeeding

What danger signs to watch out for

Avoid medicines for diarrhea that you can buy without a prescription unless your provider tells you to use them. These drugs can make some infections worse.

If you have a long-term form of diarrhea, such as diarrhea caused by irritable bowel syndrome, changes to your diet and lifestyle may help.

When to Contact a Medical Professional

Contact your provider right away if you or your child shows signs of dehydration:

Decreased urine (fewer wet diapers in infants)

Dizziness or lightheadedness

Dry mouth

Sunken eyes

Few tears when crying

Schedule an appointment with your provider if you have:

Blood or pus in your stools

Stomach pains

Stomach pain that does not go away after a bowel movement

Diarrhea with a fever above 101°F or 38.33°C (100.4°F or 38°C in children)

Also contact your provider if:

The diarrhea gets worse or does not get better in 2 days for an infant or child, or 5 days for adults

A child over 3 months old has been vomiting for more than 12 hours; in younger babies, call as soon as vomiting or diarrhea begins

What to Expect at Your Hospital Visit

Your provider will perform a physical exam and ask about your medical history and symptoms.

Lab tests may be done on your stools to find the cause of your diarrhea.

Over-the-counter supplements that contain healthy bacteria may help prevent diarrhea caused by taking antibiotics. These are called probiotics. Yogurt with active or live cultures is also a good source of these healthy bacteria.

The following healthy steps can help you prevent illnesses that cause diarrhea:

Wash your hands often, particularly after using the toilet and before eating.

Use alcohol-based hand gel frequently.

Teach children to not put objects in their mouth.

Take steps to avoid food poisoning.
