Mechanism of Involvement of Intestinal Microbiota in Pathogenesis of Irritable Bowel Syndrome / 胃肠病学

ABSTRACT

The etiology and pathogenesis of irritable bowel syndrome (IBS) are not fully understood, and intestinal microbiota had been assumed as a possible factor in the pathogenesis of IBS.Increasing evidences have shown that alterations of gut microbiota were found in IBS patients and modulation of intestinal microbiota might be effective in the treatment of IBS.This article reviewed the mechanism of involvement of intestinal microbiota in pathogenesis of IBS by altering mucosal permeability, activating immune reaction, disturbing gastrointestinal motility and affecting brain-gut axis.
