Diarrhea—the frequent passage of loose, watery stool—is not a disease but a symptom of an
underlying problem It is most commonly brought on by food poisoning, especially among travelers
Transient looseness can be caused by overconsumption of laxative foods (such as prunes), heavy use
of sugarless chewing gum sweetened with sugar alcohol (such as sorbitol), and some medications
Emotional stress that causes irritable bowel syndrome may disrupt the normal bowel pattern with
alternating diarrhea and constipation; similar symptoms occur in colitis and Crohn’s disease, both
inflammatory bowel disorders In many instances, diarrhea develops without any identifiable cause,
but unless the problem persists or recurs often, this is not a cause for concern
Acute infectious diarrhea is one of the world’s most common ailments An estimated five billion
cases occur every year, and in North America, diarrhea is runner-up only to the common cold as a
cause for absences from work Although diarrhea causes fatalities due to dehydration, it is seldom a
threat in affluent, well-nourished societies, except to vulnerable groups: babies, the elderly, and
invalids
Nutrition Connection
Most cases of diarrhea are minor and short-lived and can be managed at home with simple dietary
measures, such as:
Stop solid food and rehydrate Start by eliminating all solid foods and sipping warm or tepid
drinks to prevent any further dehydration Drinking half a cup of fluid every 15 minutes or so is
usually enough Suitable drinks include water, mineral water, herbal teas, and ginger ale Clear broths
also help replace the salts and other minerals lost in a bout of diarrhea You can make your own
rehydration fluid by mixing ½ tsp (1 mL) of baking soda, a pinch of salt, and ¼ teaspoon (1 mL) corn
syrup or honey in an 8-oz (250-mL) glass of water Commercial sports drinks may help, but avoid
ones with more than 10% sugar, which can worsen diarrhea
Slowly introduce low-fiber foods When you feel like eating (but preferably not within the first 24
hours), start with low-fiber foods such as crackers, toast, rice, bananas, cooked carrots, boiled
potatoes, and chicken Often doctors will recommend bananas, rice, applesauce, and toast (called the
BRAT diet), especially for children Apples and other fruits high in pectin (a soluble fiber) help
counteract diarrhea; that’s why unsweetened applesauce is a traditional home remedy Cooked carrots
are also high in pectin Other suitable foods include salted crackers and chicken soup, which help to
replenish depleted sodium and potassium reserves
Avoid milk products until the symptoms disappear Some of the organisms that cause diarrhea
can temporarily impair the ability to digest milk
Avoid apple juice While apples or applesauce can help ease diarrhea, apple juice, can have the
opposite effect The leftover carbohydrates in apple juice that aren’t absorbed in the small intestine
are fermented by bacteria in the colon, potentially leading to diarrhea In fact, drinking too much fruit
juice of any kind is often the cause of diarrhea in toddlers
Beyond the Diet
Address diarrhea as soon as possible using the following suggestions:
Try over-the-counter (OTC) remedies OTC antidiarrheal drugs may give some relief when
diarrhea has no obvious cause or is due to a minor illness such as flu Never use a nonprescription
antidiarrhea product for more than 2 days without consulting your doctor
Call a doctor if it’s recurring Some people may have chronic diarrhea due to malabsorption of a
nutrient, such as lactose intolerance; consult a physician Other signs of illness that need medical
attention include appearance of blood, mucus, or worms; severe abdominal pain; or diarrhea
accompanied by vomiting or fever
