Chronic diarrhea has many causes. Some are caused by disease. This article focuses mostly upon those causes where you can make changes that may result in a rapid improvement in the diarrhea.
This type of diarrhea is usually painless and persistent, and there are no signs of disease such as bleeding, anemia, weight loss, or fatigue. Frequent loose stools are a daily occurrence. There may be occasional normal stools. Despite the need to stay within reach of a toilet, the person is otherwise well.
Very frequently, the diarrhea is due to something in the diet that is taken in excess. Usually this is an excess of a sugar or chemical substance. Common examples are alcohol and caffeine. An excess of alcohol, especially beer and wine, may cause loose stools the next day. The best test is to stop alcohol completely and see if the diarrhea stops. If it does, drinking may be cautiously resumed at a more modest level.
Caffeine-containing drinks have a laxative potential. More than two or three cups of coffee or tea daily can often cause diarrhea. Withdraw gradually over the course of a few days to avoid headache and try going without for awhile. Decaffeinated drinks may still contain chemicals that can loosen the stools. Most people can tolerate smaller amounts well.
Some sugars can cause diarrhea. For example, the artificial sugar sorbitol is used as a sweetener. It is often used in diet gums and candies or as a sugar substitute in coffee or tea. It has no calories, but is a known laxative if taken in sufficient amount. Mannitol is another sweet substance frequently found with sorbitol.
Fructose is a natural calorie-containing sugar found in fruit. It is one reason why large amounts of fruit can cause diarrhea. It may also be found in candies, soft drinks, honey, and preservatives and, in sufficient amounts, can cause diarrhea. Many people notice that their bowel movements are looser and more frequent in the summer when fresh fruits and vegetables are freely available. Moderating intake should help.
Lactose intolerance is the cause of chronic diarrhea in some people. Lactose is a sugar that is contained in cow’s milk. Its proper digestion requires the adequate presence of an enzyme (lactase) in the wall of the small intestine. Treatment of lactose intolerance initially involves the elimination of all lactose-containing products from the diet. Moderate amounts of dairy or modified dairy products may be gradually reintroduced into the diet as tolerated.
Laxatives are frequently present in herbal medicines. Senna tea is an obvious example. But herbs with a laxative effect like senna can be found in many other popular remedies. The contents of an herbal remedy may not all appear on the package. Only by stopping the medicine for a trial period can one be confident that it is not the cause of chronic diarrhea.
