肠易激综合征发病机制的研究进展

Advances in Study on Pathogenesis of Irritable Bowel Syndrome

肠易激综合征(IBS)是一种常见的功能性胃肠道疾病,临床表现主要为腹痛、腹胀以及排便习惯改变。目前,IBS的发病机制尚未完全明确。研究认为IBS是多因素共同作用的结果,相关因素包括生活方式、基因多态性、食物过敏、心理因素、脑-肠轴异常以及肠道菌群失调等。本文就IBS发病机制的研究进展作一综述。

Studies showed that IBS was caused by many factors,including life style,gene polymorphism,food hypersensitivity,psychological factors,brain-gut axis abnormality and intestinal flora disorder.
