Popular diabetes drugs may impact colonoscopy prep quality
NCT ID NCT07127354
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how GLP-1 and GIP agonists (medications used for diabetes and weight loss) affect bowel preparation quality in adults scheduled for a colonoscopy. Researchers want to see if these drugs increase the chance of poor bowel prep, and whether pausing the medication for one dose improves outcomes. About 132 participants will be randomly assigned to either hold or continue their medication before the procedure.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Adult patient (Age 18 years or older) * Patient scheduled for outpatient screening, surveillance, or diagnostic colonoscopy * Using a GLP-1 or GIP agonist at a stable dose for at least one month Exclusion Criteria: * Unable to provide informed consent, e.g., dementia * Patient refuses the USMSTF recommended bowel cleansing regimen for patients with diabetes or obesity (split-dose 4 liters polyethylene glycol + 15 mg bisacodyl the afternoon before; low residue diet 3 days before colonoscopy; clear liquid diet the day before colonoscopy) * Risk factors for inadequate bowel preparation besides diabetes and obesity with a likelihood ratio of 1.6 or greater: 1. Cirrhosis 2. Parkinson's disease 3. Dementia 4. Tricyclic antidepressant use 5. Opioid use 6. Gastroparesis\* or suspected gastric outlet obstruction on pre-procedure imaging (\*defined based on a documented 4-hour solid phase gastric emptying study or prior history of retained gastric contents during upper endoscopy) 7.
