Irritable Bowel Syndrome (IBS) is a functional gastrointestinal disorder. Symptoms stem from a dysfunctional gut, characterized by chronic abdominal pain and constipation, diarrhea or alternating of both.
In Ayurveda, a similar condition is described at length: grahani or sangrahani. Grahana, a Sanskrit word, means “retaining ability.”
Caraka Cikitsa Sthāna 19 refers to Diarrhea and Irritable Bowel Syndrome as Atisara. This condition resembles clinical diarrhea which is defined as the frequent passing of liquid stools within a short period. Diarrhea, among adults, is categorized in two ways, either as acute sudden onset or chronic relapsing for longer than two weeks.
