Abdominal bloating and visible distention are common, but the mechanisms behind these bothersome symptoms are unclear. Little epidemiological data on bloating, or separate data on distention, exist. In this issue of Gut, Jiang et al present a population-based study from Olmstead County, Minnesota, including 2259 subjects, where they used validated questionnaires and abstracted data from the medical records of the included subjects. The age- and sex-adjusted prevalence for bloating was 19.0% and for visible abdominal distention 8.9%. Female gender and somatisation, assessed with a somatic symptom check list (SSC), were found to be risk factors for bloating alone and separately for distention. Moreover, female gender, higher SSC scores, constipation-predominant IBS, dyspepsia and widespread GI symptoms were predictors for having distention over bloating alone. When looking at different functional GI disorders (FGID) or gastroesophageal reflux disease (GORD), the proportion of subjects with bloating and/or distention separately was higher in each
