Diarrhoea is the passage of 3 or more loose or liquid stools per day (or more frequent passage than is normal for the individual).
Diarrhea — loose, watery and possibly more-frequent bowel movements — is a common problem. Sometimes, it’s the only symptom. At other times, it may 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 means that there’s another problem — such as irritable bowel syndrome (IBS) or a more serious disorder, including ongoing infection, celiac disease or inflammatory bowel disease (IBD).
