What this trial studies

This study investigates the effectiveness of a low FODMAP diet in children diagnosed with irritable bowel syndrome (IBS). It is a single-center, prospective, single-blind trial that includes a crossover design, allowing participants to experience both low and standard FODMAP diets. The trial consists of four phases: a run-in phase to assess baseline symptoms, followed by a 14-day intervention with either a low or standard FODMAP diet, a wash-out period, and then a final 2-week period on the alternate diet. Metabolomic analysis of fecal and urinary samples will be conducted to evaluate changes in metabolite profiles associated with dietary interventions.

Why it matters

Potential benefit: If successful, this study could provide a dietary management option that significantly alleviates IBS symptoms in children.

How similar studies have gone: Previous studies in adults have shown success with low FODMAP diets in managing IBS symptoms, but evidence in children is limited, making this approach relatively novel.
