A dietitian‐led low‐FODMAP diet webinar: a pre–post study evaluating its impact on symptoms of irritable bowel syndrome

Abstract

AbstractBackgroundEvidence suggests that the low fermentable oligo‐, di‐, mono‐saccharides, and polyols (FODMAP) diet improves irritable bowel syndrome (IBS) symptoms when delivered by a dietitian. However, demand for dietetic appointments exceeds supply. Prerecorded webinars are acceptable and cost‐effective for delivering first‐line IBS dietary advice.MethodologyThis study, using a pre–post design, aimed to evaluate the effectiveness of a low‐FODMAP diet restriction phase webinar at improving IBS symptoms. Participants with self‐reported IBS symptoms were asked to report their IBS symptoms, stool frequency, stool consistency and IBS medication use, before and 8 weeks postwebinar via an online questionnaire. The presence and severity of participants' symptoms and bowel habits were captured using validated tools and a global symptom question.ResultsIn total 228 participants responded to both pre‐ and postsurveys. A statistically significant improvement in all symptoms was observed 8 weeks postwebinar (p < 0.05). The proportion of participants rating their overall symptoms as moderate‐to‐severe reduced from 85.5% at baseline to 34.6% postwebinar (50.9% reduction [p < 0.001]). The proportion of participants reporting normal stool consistency and frequency significantly increased postwebinar (23.2%–39.9% [p < 0.001] and 76.3%–89% [p < 0.001], respectively). Satisfactory relief of symptoms increased from 16.7% to 53.1%, (p < 0.001) 8 weeks postwebinar.ConclusionsThese results are comparable with literature on the efficacy of face‐to‐face delivery of low‐FODMAP diet education. Dietitians should consider directing triaged patients with IBS, who have tried first‐line dietary advice, to this webinar as an alternative or alongside current practice.
