Safety
GLP-1 medicines before surgery or sedation
GLP-1 treatment can delay gastric emptying, and the current labels warn about pulmonary aspiration during general anesthesia or deep sedation. The procedure team needs to know about treatment in advance.
Why the stomach matters
Aspiration occurs when stomach contents enter the airways. Labels report this concern in people taking GLP-1 medicines during procedures involving anesthesia or deep sedation, including cases despite reported fasting.
The label warning does not establish one medicine-hold interval that is right for every procedure and patient. Stomach symptoms, escalation, other medical conditions, diabetes control, and the planned anesthesia can affect the decision.

Information to give the procedure team
Provide the exact brand or compounded formulation, route, dose, date of the last dose, and whether you recently started or escalated. Describe nausea, vomiting, bloating, severe constipation, or other stomach symptoms honestly.
Tell the team about diabetes medicines and prior low-glucose problems. If a medicine is withheld, diabetes management or another treatment objective may need a plan. A clinic's general scheduling advice is not a substitute for the anesthesia team's assessment.

Follow the coordinated instructions
Ask the anesthesia team and prescriber to agree on fasting, medication timing, and any additional precautions. This page intentionally does not prescribe a universal day-count hold rule from an older internet article.
Contact the procedure team if symptoms, dosing, or the planned procedure change. Do not skip, restart, or take an extra dose on your own to fit a calendar. A long interruption may require re-escalation and should be discussed before resuming treatment.

Restarting after the procedure
Ask when it is appropriate to resume the exact product, particularly if food and fluid intake remain limited or significant nausea continues. The former maintenance dose is not automatically the correct restart after a lengthy interruption.
Keep both teams informed about complications or symptoms. Manufacturer instructions and clinical judgment should guide the plan; a medication review site cannot account for the individual anesthesia and metabolic risks.
