中药调节肠道菌群治疗肠易激综合征研究进展

肠易激综合征(irritable bowel syndrome,IBS)是常见的慢性功能性胃肠疾病,主要临床特点是反复腹痛或腹部不适,并伴有排便频率或粪便性质的改变[1]。根据确诊患者粪便性状的不同,可将IBS分为便秘型(irritable bowel syndrome with constipation,IBS-C)、腹泻型(irritable bowel syndrome with predominant diarrhea,IBS-D)、混合型(irritable bowel syndrome with mixed bowel habits,IBS-M)、未定型(irritable bowel syndrome unclassifified,IBS-U)[2]。
