Definition:

Non-constipation IBS is a term used in research trials to identify irritable bowel syndrome (IBS) patients who do not experience the symptom of constipation. Non-constipation IBS can be differentiated from diarrhea predominant IBS (IBS-D), in that IBS-D patients are those whose predominant symptom might be diarrhea, but who experience occasional constipation.
