Gas relief drug may skew stomach bug tests, new study warns
NCT ID NCT07293234
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This pilot study will check if simethicone, a medicine used to reduce gas during endoscopy, makes it harder to detect H. pylori bacteria. About 100 adults with a positive H. pylori test will take simethicone or a placebo before their procedure. The goal is to see if the drug lowers detection rates, which could change how doctors prepare patients for testing.
