May 24, 2016
The new Rome IV criteria classify the functional bowel disorders into five distinct categories, including irritable bowel syndrome (IBS), functional constipation, functional diarrhea, functional abdominal bloating/distention, and unspecified functional bowel disorder. A new category for opioid-induced constipation, which is distinct from the functional bowel disorders, has been added.
