What Is IBS?
Irritable bowel syndrome (IBS) is a digestive disorder that many people have, but few people talk about. It is estimated that IBS affects up to 15% of the population with its symptoms of chronic abdominal pain and major disturbance of bowel functioning. IBS can entail bouts of urgent diarrhea, episodes of chronic constipation, or a pattern of alternating between the two. IBS is considered a functional disorder, in that it involves a malfunction in how the intestinal system works, but doesn’t show up in any visible disease process or tissue damage.
