Low-FODMAP diet offers hope for celiac sufferers with ongoing gut pain
NCT ID NCT03678935
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether cutting out certain carbs (FODMAPs) can help people with celiac disease who still have stomach issues even after following a gluten-free diet. Researchers surveyed and then ran a controlled trial with 80 adults who had celiac disease and irritable bowel-like symptoms. The goal was to see if a low-FODMAP diet could reduce their ongoing gut discomfort.
