Diarrhea describes bowel movements (stools) that are loose and watery. It is very common and usually not serious. Many people will have diarrhea once or twice each year. It typically lasts two to three days and can be treated with over-the-counter (OTC) medicines. Some people often have diarrhea as part of irritable bowel syndrome or other chronic diseases of the large intestine.
Doctors classify diarrhea as "osmotic," "secretory," or "exudative."
Stress, spicy foods, type A personality. Which of these causes most stomach ulcers? The answer: none of them. Research shows that most ulcers -- 80% of stomach ulcers and 90% of those in the duodenum, the upper end of the small intestine -- develop because of infection with Helicobacter pylori (H. pylori).
Osmotic diarrhea means that something in the bowel is drawing water from the body. A common example is sorbitol, a sugar substitute found in sugarless candy and gum that isn't absorbed by the body but draws water into the bowel, resulting in diarrhea.
Secretory diarrhea occurs when the body is releasing water into the bowel. Many infections, drugs, and other conditions cause secretory diarrhea.
Contact your doctor if you have prolonged diarrhea, bloody diarrhea, or a fever that lasts more than 24 hours. Also see your doctor promptly if vomiting prevents you from drinking liquids to replace lost fluids.
How Is Diarrhea Treated?
If you have a mild case of diarrhea, you can just let it run its course, or you can treat it with an over-the-counter medicine. Common brand names include Pepto-Bismol, Imodium A-D, and Kaopectate, which are available as liquids or tablets. Follow the instructions on the package.
In addition, you should drink at least six 8-ounce glasses of fluid per day. Choose fruit juice without pulp, broth, or soda (without caffeine). Chicken broth (without the fat), tea with honey, and sports drinks are also good choices. Instead of drinking liquids with your meals, drink liquids between meals. Drink small amounts of fluids frequently.
