Background

Low FODMAP (Fermentable Oligo-, Di-, Monosaccharides and Polyols) diet (LFD) has been shown to be efficient in irritable bowel syndrome (IBS). The objective of this study was to investigate the impact of a LFD on IBS-like symptoms, disease activity and quality of life in inflammatory bowel disease (IBD) (SIBDQ).

Methods

Randomised, non-blinded controlled six weeks trial of IBD patients in remission or mild to moderate disease activity and IBS-like symptoms (Rome III criteria) were allocated to either LFD or normal diet. Patients had to fill out the IBS symptom severity scale (IBS-SSS) and quality of life (IBS-QOL) at week 0 and 6 on a web-based program and IBD activity symptom scores: SCCAI for ulcerative colitis (UC), HBI for Crohn's disease (CD) and quality of life (SIBDQ) on paper.

Results

A total of 89 patients: 61 (69%) UC and 28 (21%) CD, 67 (75%) females, median age 40 years (20–70) were randomized: 44 to LFD and 45 as controls. Significant reduction in IBS-SSS at week 6 in LFD compared to controls (114 vs. 68), p = 0.02 was observed. In UC a significant reduction of SCCAI (0.7 vs. 0.1), p = 0.02 but not in CD was observed. SIBDQ improved significantly in LFD (9.1–0.9), p < 0.001.

Conclusion

LFD is effective in IBD patients in remission or mild-to moderate activity, predominantly improving IBS-like symptoms in patients and further reduce disease activity for UC and improve SIBDQ.
