Diarrhea has several common causes including eating contaminated foods, water or other beverages; viral infections (the "stomach flu"); lactose (dairy product) intolerance; food allergies; and intestinal parasites. Some medications, such as certain antibiotics, can cause diarrhea. It can also be caused by seemingly unrelated things like menstrual cramps, overuse of alcohol, stress, or panic attacks.
Diarrhea can affect the absorption (and therefore the effectiveness) of oral medications. If you have significant diarrhea and take birth control pills, use a backup birth control method like condoms until you start your next period. However, keep taking your pills on schedule. Contact your healthcare provider about possible effects of diarrhea on other medications you're taking.
This advice deals only with diarrhea lasting two weeks or less and that is not occurring together with or as a result of another medical problem.
Signs and Symptoms
- Frequent loose or watery bowel movements
- Cramping or abdominal pain
- Fever and/or chills
- Drink four to eight ounces of clear liquid every hour. Drink mostly water, but also drink non-caffeinated drinks like sports drinks, broth/bouillon, flat sodas or ginger ale, weak teas, or diluted juices.
- If you wish, you may take a non-prescription anti-diarrheal medication.
- Unless a healthcare provider tells you to do so, don't take an antidiarrheal medication if you have a fever, severe abdominal pain, or blood or mucous in your stool.
Choose: soft, starchy foods; lean meats; cooked vegetables; non milk-based soups; fruits high in potassium such as bananas and avocados; and yogurt (especially with lactobacillus acidophilus).
Avoid: alcohol; caffeinated foods or beverages; over-the-counter medication with ibuprofen or aspirin; spicy, acidic or fried food; milk products (except for yogurt); raw vegetables and fruits (other than those listed above); bran; nuts; and gas-producing foods.
