Diarrhea is loose, watery stools. Having diarrhea means passing loose stools three or more times a day. Acute diarrhea usually lasts 1 or 2 days and goes away on its own. If it is lasting more than 2 days, that could be a sign of a more serious problem.
Chronic diarrhea symptoms may be continual or they may come and go. Acute diarrhea us usually caused by a bacterial, viral, or parasitic infection. Chronic diarrhea is usually related to an irritable bowel syndrome or an intestinal disease such as Crohn’s disease.
Other causes can be parasites, food intolerances and sensitivities or a reaction to medicines.
Sometimes, the cause of diarrhea cannot be found, but if it doesn’t resolve within 1 or 2 days, a doctor visit may be necessary.
