Coeliac disease (CD) is an autoimmune disorder in which gluten ingestion induces inflammation in the small intestines. While a gluten-free diet (GFD) alleviates gastrointestinal (GI) symptoms in the majority of CD patients, there is a subset of patients following a strict GFD that still experience GI symptoms. The aim of this study is to determine if a low fermentable, oligosaccharides, disaccharides, monosaccharides and polyols (FODMAP) diet would help reduce persistent symptoms in 44 CD patients following a strict GFD. Participants were randomised to receive a structured 21-day dietary plan of either a low-FODMAP GFD or a high-FODMAP GFD and were evaluated for GI symptoms, psychological wellbeing and quality of life at baseline and the end of the intervention. This study found quality of life and abdominal pain improved significantly in the low-FODMAP group compared to the high-FODMAP group. Based on these findings, the authors conclude a short-term low-FODMAP diet helps to improve persistent GI symptoms and enhance general wellbeing in this subgroup of CD patients. Further evaluation is recommended to better understand the long-term clinical effects of FODMAPs in CD patients.
A subset of patients with celiac disease (CD) on a gluten-free diet (GFD) reported the persistence of functional gastrointestinal disorders. Foods containing fermentable, oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAP) can trigger a broad range of gastrointestinal symptoms in sensitive individuals. We evaluated the effects of a low FODMAP diet (LFD) on gastrointestinal and psychological symptomatology in CD patients. A total of 50 celiac patients on GFDs and with persistence of gastrointestinal symptoms were included. The patients were randomly allocated to one of two dietary groups-one on a low FODMAP GFD (LF-GFD, = 25) and the other on a regular GFD (R-GFD, = 25)-for 21 days. Psychological symptomatology and quality of life were evaluated by the Symptom Checklist-90-R (SCL-90) and the Short Form (36) Health Survey (SF-36) questionnaires, respectively. Gastrointestinal symptomatology and general well-being were evaluated by visual analogue scale (VAS) scores. After 21 days, 21 and 23 patients completed the dietary treatment on LF-GFD and R-GFD, respectively. A reduced global SCL-90 index ( < 0.0003) was found in the LF-GFD group but not in the R-GFD one. However, the SF-36 scores did not differ between groups after treatment. The VAS for abdominal pain was much lower, and the VAS for fecal consistency enhanced after treatment in the LF-GFD group. General well-being increased in both groups but with a much higher improvement in the LF-GFD ( = 0.03). A short-term LFD regimen helps to improve the psychological health and gastrointestinal symptomatology with enhanced well-being of CD patients with persisting functional gastrointestinal symptomatology. The long-term clinical effects of LFD in particular subgroups of CD patients need further evaluation.
