Abstract

Background & aims 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.Methods Abdominal girth measured by ambulatory abdominal inductance plethysmography and bloating severity was recorded over 24 hours in 39 IBS-constipation (ages, 18-73 years) and 29 IBS-diarrhea patients (ages, 20-59 years) meeting Rome II criteria. Within 1 week, rectal sensory thresholds were assessed with a barostat using the ascending method of limits and tracking.Results IBS patients who suffered with bloating alone had lower thresholds for pain (P = .005), desire to defecate (P = .044), and first sensation (P = .07) compared with those who had concomitant distention irrespective of bowel habit. When patients were grouped according to sensory threshold, hyposensitive individuals had distention significantly more than those with hypersensitivity (P = .001), and this was observed more in the constipation subgroup. Static and dynamic compliance did not differ among any of the groups.Conclusions The symptom of bloating alone is associated with visceral hypersensitivity, suggesting that the pathogenesis of bloating and distention may not be the same. Consequently, treatment approaches may have to be different, and measuring visceral sensation could have utility in choosing the right therapeutic modality.

  • Approximately 20% of patients with IBS are viscerally hyposensitive or insensitive to mechanical distension, more commonly those with IBS-C than IBS-D.

    “Approximately 20% of patients with IBS are viscerally hyposensitive or insensitive to mechanical distension, more commonly those with IBS-C than IBS-D, with one study suggesting that the degree of insensitivity correlated with abdominal distension (ie, a true physical increase in abdominal girth).43”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
