Objective: To evaluate change in gastrointestinal (GI) symptoms and quality of life (QOL) before and after implementing the Fermentable Oligosaccharides, Disaccharides, Monosaccharides and Polyols (FODMAP) elimination diet with guidance by a registered dietitian (RD) and to learn about patients' experience with the FODMAP elimination diet for irritable bowel syndrome (IBS).
Methods: The GI symptom rating scale for IBS (GSRS-IBS) and the IBS-QOL were administered before and after the 4-week elimination diet and analyzed using Wilcoxon signed rank test. Qualitative one-on-one phone interviews focusing on the elimination diet experience were completed after a 4-week elimination diet, and content analysis was completed using transcripts.
Results: Participants (n=16) were predominantly female (75%) and White (81%), with an average age of 47 (±14) years. Significant differences (p=0.02) in the total GSRS-IBS median (IQR) score (45.5 (29.9, 55.6) vs 36.7 (24.7, 48.8)) after elimination (range of 1391 with higher score indicating more symptoms). Total IBS-QOL median (IQR) score significantly improved after elimination (94.5 (78.8, 110.5) vs. 73.5 (58.0, 100.3)), respectively; (p=0.002), (range of 35-175 with higher score indicating more symptoms) indicating an improved QOL after the elimination diet. Eight of 12 participants discussed receiving physician recommendations before meeting with the RD. After meeting with the RD, 11 of 12 participants reported RD's education materials as helpful, and five of 12 discussed that the most beneficial aspect of the RD was having the RD's support throughout the diet to improve adherence.
Conclusion: Inclusion of the RD during the FODMAP elimination diet improves GI symptoms and QOL through helpful resources and support, reinforcing the role of the RD when a FODMAP elimination diet is recommended.
