Can a special diet soothe tummy troubles in kids with IBS?
NCT ID NCT06618677
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a low FODMAP diet (limiting certain carbs) can reduce stomach pain and bloating in children with irritable bowel syndrome (IBS). Seventy children aged 4–18 followed either a low or standard FODMAP diet for two weeks, then switched after a break. Researchers measured symptoms and checked gut bacteria and waste products to see how the diet works.
