Diarrhea occurs in all age groups and populations. Depending on the cause, diarrhea can be short term (acute) and disappear relatively quickly, such as when it occurs with viral gastroenteritis. Diarrhea can also be continuous or recurring over a longer period of time (chronic), such as when it occurs with inflammatory bowel disease and irritable bowel syndrome. Diarrhea can range in severity from mild and self limiting to serious and life threatening.
