Pause or pop? study tests if stopping GLP-1 drugs before endoscopy reduces stomach risks
NCT ID NCT06533527
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed Phase 4 trial at the Cleveland Clinic enrolled 69 adults with type 2 diabetes or obesity who take GLP-1 medications. Participants were randomly assigned to either continue or pause their GLP-1 drug before an upper endoscopy. The goal was to see if holding the medication reduces the amount of food or liquid left in the stomach, which can interfere with the procedure or cause dangerous aspiration. The study did not test a new treatment but aimed to improve safety guidelines for common procedures.
