Multicenter StudyThe overlap of upper functional gastrointestinal disorders with irritable bowel syndrome in Chinese outpatients: A multicenter study.
Irritable bowel syndrome (IBS) is a common functional bowel disease, and the overlap with upper functional gastrointestinal disorders (FGIDs) is popular. However, the coexistent upper GI symptom profiles, upper FGID spectra, and related risk factors among IBS subjects remain unclear in mainland of China. ⋯ The study provides detailed overlap spectra of upper FGID with IBS. Mixed IBS is an important risk factor for IBS-FD overlap, which deserved more concern.
