Pausing GLP-1 drugs before colonoscopy: could a One-Week break improve bowel prep?
NCT ID NCT07736963
First seen Jul 30, 2026 · Last updated Sep 04, 2026 · Updated 3 times
Summary
This trial tests whether stopping GLP-1 receptor agonists (medications like semaglutide and liraglutide) for one week before a colonoscopy leads to better bowel preparation and fewer repeat procedures. Researchers will compare bowel cleanliness and detection rates of polyps between people who pause the drug and those who continue it. The study includes adults aged 18 to 70 scheduled for a colonoscopy, aiming to establish clear discontinuation recommendations.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- GLP-1 receptor agonists (drugs like semaglutide and liraglutide)
- What this could lead to
- If it works, this could lead to clear guidelines on when to pause GLP-1 drugs before colonoscopy, improving procedure success and patient experience.
- What could go wrong
- This is a small, early-stage trial focused on a procedural question, not a new treatment. Results may not apply to all GLP-1 users or colonoscopy settings.
