Diarrhea means that you have a change in your bowel movements and pass unusually loose stools. Stool is what is left after your digestive system (stomach, small intestine, and colon) absorbs nutrients and fluids from what you eat and drink. Stool passes out of the body through the rectum. If fluids are not absorbed, or if your digestive system produces extra fluids, stools will be loose and watery. Loose stools are larger than usual. People with diarrhea often have frequent bowel movements and may pass more than a quart of watery stool a day.
What other symptoms accompany diarrhea?
People who have diarrhea may also have
crampy pain in the abdomen, the area between the chest and the hips
swelling in the abdomen
an uncomfortable feeling around the anus
an urgent need to have a bowel movement
an inability to control their bowels (fecal incontinence)
chills
fever
Also, people with diarrhea may feel sick to their stomach or be dehydrated.
What is dehydration?
Dehydration means that your body does not have enough fluid to work properly. Every time you breathe out, sweat, urinate, or have a bowel movement, you lose fluid. Diarrhea increases the amount of fluid lost in bowel movements. Along with the fluid, you lose salts-chemicals that your body needs to work properly. The loss of fluids and salts can be serious, especially for babies and young children and for older people.
The signs of dehydration in adults are
being thirsty
urinating less often than usual
having dark-colored urine
having dry skin
feeling tired or dizzy
fainting
In addition, the kidneys could stop working.
The signs of dehydration in babies and young children are
having a dry mouth and tongue
crying without tears
having no wet diapers for 3 hours or more
having a high fever
being unusually sleepy or drowsy
Also, when children have diarrhea, their skin seems to lose its elasticity. It does not flatten back to normal when pinched and released.
Who gets diarrhea?
Anyone can get diarrhea. This common problem can last a day or two or for months or years, depending on the cause. Most people get better on their own, but diarrhea can be serious for babies and older people if lost fluids are not replaced. Many people throughout the world die from diarrhea because of the large volume of water lost and the accompanying loss of salts.
What causes diarrhea?
Diarrhea can be caused by
bacteria, viruses, or parasites (tiny organisms that live inside a larger organism)
medicines such as antibiotics
foods such as milk
diseases that affect the stomach, small intestine, or colon, such as Crohn's disease and irritable bowel syndrome
Sometimes no cause for diarrhea can be found.
When should I talk to a doctor?
Diarrhea often goes away by itself, but it can be a sign of a more serious problem. You should talk to your doctor if your diarrhea lasts for more than 3 days. You should also call your doctor if you have
signs of dehydration
a severe pain in your abdomen or rectum
a fever of 102°F or higher
stools that are bloody or black and tarry
Children younger than 12 become dehydrated much more easily than adults. If your child does not improve after 24 hours or has any of the following symptoms along with diarrhea, call the doctor. (This is especially important if your child is 6 months old or younger.)
stools containing blood or pus
black stools
a fever above 101.4°F
signs of dehydration (see page 4)
What tests might be done?
Your doctor may want to perform tests to find the cause of the diarrhea:
a physical exam
stool or blood tests to look for bacteria, parasites, or other signs of disease or infection
fasting tests to see whether diarrhea goes away when you stop eating a particular food
a sigmoidoscopy, an examination of the inside of the rectum and part of the colon
a colonoscopy, an examination of the inside of the whole colon
For a sigmoidoscopy or colonoscopy, the doctor uses a thin, flexible, lighted tube with a lens on the end.
How is diarrhea treated?
In many cases of diarrhea, replacing lost fluid and salts is the only treatment needed.
Adults should consume broth, soup, fruit juices, soft fruits, or vegetables.
Children should drink a special liquid that has all the nutrients they need. These solutions are sold without a prescription in grocery stores or drugstores. Pedialyte, Ceralyte, or Infalyte are some examples.
Taking medicine to stop diarrhea can be helpful in some cases. Medicines that are available without a doctor's prescription include loperamide (Imodium) and bismuth subsalicylate (Pepto Bismol and Kaopectate). Stop taking these medicines if symptoms get worse or if diarrhea lasts more than 2 days.
If a particular food or medicine is the cause, you should avoid it.
Also, while you are waiting for the diarrhea to end, you should avoid foods that can make it worse:
milk and milk products, such as ice cream or cheese
high-fat or greasy foods, such as fried foods
foods that have a lot of fiber, such as citrus fruits
very sweet foods, such as cakes and cookies
As you feel better, begin eating soft, bland food, such as bananas, plain rice, boiled potatoes, toast, crackers, cooked carrots, and baked chicken without the skin or fat. Children can eat bananas, rice, applesauce, and toast (sometimes called the BRAT diet).
Traveler's Diarrhea
People who are visiting other countries and eat food or drink water contaminated by bacteria, viruses, or parasites can develop traveler's diarrhea.
You can prevent it by being careful:
Avoid drinking tap water or using ice cubes made from tap water.
Avoid drinking unpasteurized milk or eating dairy products made from it.
Avoid eating raw fruits and vegetables unless they can be peeled and you peel them yourself.
Do not eat raw or rare meat or fish.
Do not eat meat or shellfish that is not hot when served to you.
Do not eat food sold by street vendors.
You can safely drink bottled water, carbonated soft drinks, and hot drinks like coffee or tea.
Points to Remember
Diarrhea is a common problem.
Diarrhea is caused by bacteria, viruses, parasites, some foods or medicines, or diseases that affect the digestive system.
Diarrhea is dangerous if you become dehydrated.
Replacing lost fluids is the main treatment for diarrhea.
Talk to a doctor if you have strong pain in the abdomen or rectum, a fever, blood in your stool, signs of dehydration, or severe diarrhea for more than 3 days (1 day in the case of children).
