Diarrhea is loose, watery, or frequent stools. A person with diarrhea typically passes stool more than three times a day. Acute diarrhea is a common problem that usually lasts less than 2 weeks and goes away on its own without any special treatment. Prolonged diarrhea, persisting more than 2 weeks, or diarrhea accompanied by a fever, bleeding, dehydration, or pain may be a sign of a more serious problem.
Frequent or loose stools
Risk factors for developing diarrhea include:
- Lactose intolerance
- Diet, including inadequate fiber intake or food intolerances
- Irritable bowel syndrome (IBS)
- Inflammatory bowel disease (Crohn’s disease and ulcerative colitis)
- Other medical problems or medications
When to See a Doctor
Occasional abdominal distress such as cramping, bloating or diarrhea may result from a number of causes and often resolve on their own. If your symptoms seem severe, have not resolved within a few days, or if they persist or recur, it’s time for a thorough evaluation and consultation with a specialist.
Treatment options for individuals with diarrhea vary and may include the following:
- Hydration (replacing lost fluids)
- Over-the-counter or prescription medications or a combination
- Treatment of any underlying medical conditions
The foremost diagnostic "test" for any condition is a thorough exam and consultation with a physician, including a review of your individual and family history. In addition, your physician may recommend any of the following tests or procedures, which may provide further diagnostic value:
- Biopsy, if needed (can be performed in conjunction with other procedures)
- Blood tests
- Stool tests
People of all ages can get diarrhea, and the average adult has a bout of acute diarrhea about four times a year. Frequent hand washing will reduce your chances of contracting a viral infection which is the most common cause of diarrhea in the U.S. People with food intolerances or other digestive diseases may make diet or lifestyle changes.
