Summary

This study tests whether a simple biofeedback technique—teaching people to control their abdominal and chest muscles using a video—can reduce visible bloating after meals. 100 adults with irritable bowel syndrome, dyspepsia, or functional bloating will be randomly assigned to either the biofeedback exercises or a placebo (sham measurements and a sugar pill). The main goal is to see if bloating scores improve after four weeks.

What this could mean

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

Active substance: biofeedback (breathing and muscle exercises)
What this could lead to: If it works, this could offer a simple, drug-free way to reduce visible abdominal bloating after meals.
What could go wrong: This is a small, early-stage trial testing a technique that was previously complex. The placebo group also receives attention, so the real benefit may be modest.
