Overview
Diarrhea — loose, watery and possibly more-frequent bowel movements — is a common problem. It may be present alone or be associated with other symptoms, such as nausea, vomiting, abdominal pain or weight loss.
Luckily, diarrhea is usually short-lived, lasting no more than a few days. But when diarrhea lasts beyond a few days into weeks, it usually indicates that there's another problem — such as irritable bowel syndrome (IBS) or a more serious disorder, including persistent infection, celiac disease or inflammatory bowel disease (IBD).
