Diarrhea is loose, watery or frequent stools. If you have diarrhea, you may pass stool more than 3 times a day.
- Acute diarrhea usually lasts less than 2 weeks and goes away on its own without any special treatment.
- Prolonged diarrhea, lasting more than 2 weeks, or diarrhea accompanied by a fever, bleeding, dehydration or pain may be a sign of a more serious problem.
