Why won't my diahrrhea stop?

See a doctor: There are many causes of diarrhea, from food poisoning and infection to inflammatory bowel disease and mal-absorption. Diarrhea, especially long-standing diarrhea, can have serious health consequences, such as malnutrition, dehydration, and even imbalances in your body's potassium and other electrolytes. If you have persistent diarrhea, see your doctor.
