Diarrhea is a symptom in which changes in bowel movements produce loose watery stool more than three times per day. It may be caused by different factors, such as parasites, bacterial infection, viral infection, medication side effects or gastrointestinal diseases like ulcerative colitis, Crohn's or celiac disease. If not controlled, diarrhea may lead to detrimental effects, such as dehydration, electrolyte imbalance, anemia, low blood pressure, weight loss and hypoglycemia. Certain dietary modifications may help improve or stop diarrhea.
Decrease Fiber Intake
High-fiber food such as legumes produces bulk in the intestines and may act as a natural laxative in the body. In addition, high fiber food may produce gas, resulting in bloating, pain and discomfort. Avoid nuts, whole grain, bran products, and raw fruits and vegetables. Once diarrhea has ceased, high-fiber food may be added again to the diet.
Avoid Milk and Dairy Products
Dairy products may be hard to digest when having diarrhea. Some people suffer from lactose intolerance, a condition in which the lack of lactase, an enzyme necessary to break down lactose, may cause indigestion and diarrhea. Avoid products such as whole milk, sour cream and ice cream. People who are not lactose intolerant can reintroduce dairy into their diets once diarrhea has subsided.
Avoid High-Fat, Fat Substitutes and Greasy Food
A high-fat meal may be irritating, producing gas and bloating. Avoid fried meat, poultry or fish. Avoid canned or processed meats, such as hot dogs, sausage or ham, as these are rich in fat. Some fat substitutes used in fat-free products may not be digested, causing indigestion. Avoid fat when experiencing diarrhea. Do not exceed 8 tsp. of fat a day.
Additional Foods That Worsen Diarrhea
Caffeinated beverages, such as coffee and regular soda, stimulate intestinal contractions. Avoid alcohol as it may irritate the intestines and decrease absorption of fluids, resulting in diarrhea exacerbation. Alcohol sugars, such as sorbitol and xylitol, are fermented in the intestine, producing gas and bloating. These types of sugars, found in sugar-free gum and candy, may worsen diarrhea. Hydration is an important part of the recovery process. Drink plenty of clear fluids, such as water and broth, but avoid beverages and fruit juices high in sugar. Avoid very hot and cold foods. Temperature changes may upset the intestines.
Once diarrhea is no longer active, a regular diet can be resumed.
