Introduction

Irritable bowel syndrome (IBS) is a disorder of gut-brain interaction with complex causes. While the low FODMAP diet (LFD) can be effective, it is often complicated, expensive and restrictive. An alternative, the modified LFD (MLFD), has been proposed, although research on its effectiveness is limited. Behavioural therapies like gut-directed hypnotherapy (GDH) have also shown promise in addressing brain-gut dysregulation and improving symptoms.

Aims/Background

This study aimed to compare the effectiveness of a MLFD and LFD in improving IBS symptoms. It also assessed the impact of GDH when combined with dietary intervention.

Method

Data collected on individuals with a Rome IV IBS diagnosis was retrospectively analysed. Patients followed either a LFD or MLFD for four weeks. A separate cohort participated in a 14-week GDH intervention paired with individualised dietary advice. Information on symptoms was collected using a modified gastrointestinal symptom rating scale (mGSRS) at baseline and follow-up. Data was analysed using SPSS.

Results

Data from 130 individuals were analysed: 63 on LFD, 45 on MLFD, and 22 in the GDH group. Both LFD and MLFD significantly improved mGSRS scores (p<0.001) with no superiority associated with following a LFD. The GDH group also showed significant symptom improvement (p<0.001) with participants reporting improved understanding of the link between stress and gut symptoms.

Conclusions

The MLFD significantly improved IBS symptoms, suggesting that strict LFD restrictions may not be necessary. GDH, combined with dietetic intervention, also showed promising results, supporting more flexible and combined treatment approaches for future IBS management.
