IBS: irritable bowel syndrome, IBS-D: irritable bowel syndrome diarrhea predominant, IBS-C: irritable bowel syndrome constipation predominant, IBS-A/M: irritable bowel syndrome alternating/mixed. There were no differences in the prevalence of the different FGIDs between women versus men, except for IBS IBS-C IBS-A/M and functional abdominal bloating that were all more frequent among women and a trend for functional constipation.
