Abdominal bloating is an extremely intrusive symptom of irritable bowel syndrome (IBS) that is not always accompanied by an increase in abdominal girth (distention), raising the possibility that these 2 features of the condition may not share a common pathophysiology. A number of mechanisms have been postulated for bloating and distention, but the role of visceral sensation, which is often abnormal in IBS, has not been previously investigated, and this study aimed to address this question.
