Epidemiology of Functional Diarrhea and Comparison with Diarrhea-Predominant Irritable Bowel Syndrome: A Population-Based Survey in China

Abstract

The prevalence of functional diarrhea in China is substantially lower than that in Western countries and relatively higher than that in other Asian countries. It impaired health-related quality of life, and respondents with IBS-D have even worse quality of life. Further population-based studies are needed to investigate the epidemiology of functional diarrhea and the differences between functional diarrhea and IBS-D.
