Fiber fix? psyllium may tame fructan triggers in kids with IBS
NCT ID NCT06639984
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether psyllium, a common fiber supplement, can reduce belly pain and bloating in children with irritable bowel syndrome (IBS) who are sensitive to fructans—a type of sugar found in foods like wheat and onions. Researchers will give 110 kids aged 12-17 either psyllium or a placebo alongside fructan-containing meals, then track symptoms and gut bacteria changes. The goal is to see if psyllium can make fructans easier to digest.

Active substance
psyllium fiber
What this could lead to
If it works, this could point toward a simple fiber supplement to help children with IBS eat fructans without pain or bloating.
What could go wrong
This is an early phase 2 trial with only 110 participants, so results may not apply to all children. The benefit may be small or not work for everyone.
