Definition

By Mayo Clinic Staff

Everyone occasionally has diarrhea — loose, watery and more-frequent bowel movements. You might also have abdominal cramps and produce a greater volume of stool. Diarrhea varies in specific symptoms, severity and duration.

Acute diarrhea, which lasts from two days to two weeks, is typically caused by a bacterial, viral or parasitic infection of some sort.

Chronic diarrhea lasts longer than does acute diarrhea, generally more than four weeks. Chronic diarrhea can indicate a serious disorder, such as ulcerative colitis or Crohn's disease, or a less serious condition, such as irritable bowel syndrome.
