[Gastrointestinal symptoms and dietary intake of patients with irritable bowel syndrome following a low FODMAP diet].
Study Goal
The researchers aimed to compare gastrointestinal symptom relief and dietary compliance in IBS patients following a low-FODMAP diet with or without individual nutrition therapy.
Results Summary
Both groups experienced significant symptom relief, but compliance to the low-FODMAP diet was better in the group receiving individual nutrition therapy compared to the self-management group. High-FODMAP meal consumption dropped more sharply in the nutrition therapy group (9% vs. 36% in week 3).
Population
54 patients meeting Rome IV criteria for IBS, randomized into guided (n=28) and self-management (n=26) groups.
Effective Dosage
Not specified (dietary intervention only).
Duration
4 weeks.
Interactions
None mentioned.
| Intervention | Direction | Endpoint | Population | Dosage | Impact | Claim # |
|---|---|---|---|---|---|---|
low FODMAP diet with individual nutrition therapy | decrease | symptoms assessed by the IBS-severity scoring system (IBS-SSS) | patients with irritable bowel syndrome (IBS) meeting Rome IV criteria | 183±101 points | declined | #1 |
low FODMAP diet with self-management (online instructions) | decrease | symptoms assessed by the IBS-severity scoring system (IBS-SSS) | patients with irritable bowel syndrome (IBS) meeting Rome IV criteria | 132±110 points | declined | #2 |
low FODMAP diet with individual nutrition therapy | decrease | proportion of meals containing high FODMAP foods | patients with irritable bowel syndrome (IBS) meeting Rome IV criteria | 9% in week 3 | better compliance | #3 |
low FODMAP diet with self-management (online instructions) | decrease | proportion of meals containing high FODMAP foods | patients with irritable bowel syndrome (IBS) meeting Rome IV criteria | 36% in week 3 | compliance | #4 |
low FODMAP diet with individual nutrition therapy | decrease | gastrointestinal symptoms | patients with irritable bowel syndrome (IBS) | - | experienced relieve of symptoms | #5 |
low FODMAP diet with self-management (online instructions) | decrease | gastrointestinal symptoms | patients with irritable bowel syndrome (IBS) | - | experienced relieve of symptoms | #6 |
INTRODUCTION: High FODMAP (fermentable oligo-, di, monosaccharides and polyols) foods have been linked with worsening symptoms of IBS patients. The aim was to compare gastrointestinal symptoms and dietary intake of patients with irritable bowel syndrome following a low FODMAP diet, with or without individual nutrition therapy. MATERIALS AND METHODS: A total of 54 patients that met Rome IV criteria for IBS were randomized into two groups, guided group (individual nutrition therapy, n=28) and self-management group (learned about low FODMAP diet online, n=26). Both groups followed low FODMAP diet for 4 weeks. Four-day food records were used to assess dietary intake. Symptoms were assessed by the IBS-severity scoring system (ISB-SSS). RESULTS: The number of subjects who did not complete the study was 13, thereof five in the nutrition therapy and eight in the self-management group, leaving 23 and 18 subjects available for analysis, respectively. Symptoms declined from baseline to endpoint in both groups, by 183±101 points on average in the group receiving nutrition therapy (p< 0.001) and 132±110 points in the self-management group (p< 0.001), with no difference between groups. At baseline, about 80% of meals in both groups contained food high in FODMAP's. The corresponding proportion was 9% and 36% in week 3 in the nutrition therapy and self-management group, respectively (p< 0.001). CONCLUSION: Both groups experienced relieve of symptoms, but compliance to the low FODMAP diet was better in the group receiving individual nutrition therapy compared with the group who only received instructions on how to learn about low FODMAP diet online.
