Definition
By Mayo Clinic staffDiarrhea describes loose, watery stools that occur more frequently than usual. Diarrhea is something everyone experiences. Diarrhea often means more-frequent trips to the toilet and a greater volume of stool.
In most cases, diarrhea signs and symptoms usually last a couple of days. But sometimes diarrhea can last for weeks. In these situations, diarrhea can be a sign of a serious disorder, such as inflammatory bowel disease, or a less serious condition, such as irritable bowel syndrome.
