Abstract

Irritable bowel syndrome( IBS)is a commonly seen chronic functional bowel disease,the prevalence showed a rising trend in recent year in China. At present,the etiology and pathogenesis of IBS have not yet been fully elucidated,and may be related to intestinal gas. Intestinal gas is usually composed of 59% N2 ,21% H2 ,9% CO2 ,7%methane(CH4 )and 4% O2 ,in which H2 and CH4 are produced only by intestinal bacteria metabolism. IBS patients usually manifested as having abdominal distension and symptoms of flatulence,suggesting the occurrence of accumulation of intestinal gas. In recent years,the relationship between symptoms of IBS and intestinal gas has attracted much attention. This article reviewed the progress in study on symptoms of IBS and intestinal gas.
