Summary

This study tested a non-instrumental biofeedback technique to help people with irritable bowel syndrome or dyspepsia who experience visible abdominal bloating after meals. 41 participants were taught to control their abdominal and chest muscles using a video guide, then practiced the exercises before and after meals for four weeks. The goal was to see if this simple, drug-free approach could reduce the sensation of bloating and changes in belly size.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
biofeedback (behavioral technique)
What this could lead to
If it works, this could offer a simple, drug-free way to reduce uncomfortable bloating after meals.
What could go wrong
This is a small, early-stage trial with only 41 participants. The technique may not work for everyone, and results need to be confirmed in larger studies.
