Patients with irritable bowel syndrome (IBS) who experience the symptom of bloating can be sub-divided according to whether there is associated visible abdominal distension or not. Although bloating might well be the symptomatic manifestation of physical abdominal distension in some patients, it is less clear why others experience bloating in the absence of such distension. The aim of this study is to assess whether rectal sensitivity differs between these two groups of IBS patients. It was found that patients who experience the symptom of bloating in the absence of visible distension may do so because of increased visceral sensitivity to gastrointestinal events.
