Perioperative GLP-1 Management: What Patients Need to Know Before Surgery
If you're on a GLP-1 and have upcoming surgery, there's a specific perioperative consideration your surgical team needs to know about — and it's not automatically discussed unless you bring it up.
Why GLP-1s matter specifically for surgery
Delayed gastric emptying, the same mechanism behind GLP-1's appetite effects, raises aspiration risk during anesthesia if there's retained stomach contents at the time of a procedure. This has led some anesthesia societies to issue specific perioperative guidance around GLP-1 use.
What perioperative guidance generally involves
- Holding the GLP-1 medication for a specified period before a scheduled procedure, with the exact timeframe depending on the specific medication and dosing schedule
- Extended fasting or clear-liquid-only guidance in some protocols, beyond standard pre-surgical fasting
- Direct communication between the prescribing clinician and the surgical/anesthesia team

What patients should actually do
If you're on a GLP-1 and have any procedure requiring anesthesia scheduled, proactively tell both your prescribing clinician and your surgical team — don't wait to be asked, since not every intake process currently screens for this specifically.
