Tell the procedure team early
GLP-1 treatment belongs on the medication list provided before a procedure, even if it comes from a separate online clinic. Wegovy labeling describes reports of aspiration during general anesthesia or deep sedation and instructs patients to tell their healthcare providers about planned procedures. Do this when scheduling, rather than relying on a last-minute question at check-in. The team needs time to reconcile the prescription with the procedure and its anesthesia plan.[1]
Why a universal stopping rule is inadequate
The American Society of Anesthesiologists explains that most patients can continue their GLP-1 medicine before surgery under the 2024 multisociety guidance, while some require additional precautions. Factors include current gastrointestinal symptoms, treatment escalation and other causes of delayed stomach emptying. This is a framework for the care team, not permission to disregard individual instructions. If your written instructions differ from a general article, contact the procedure team to resolve the difference.[2]
The label and guidance answer different questions
A regulatory warning identifies a safety concern and the limits of available evidence. Professional guidance helps clinicians make decisions despite that uncertainty. Those two documents should not be read as opposing guarantees: neither promises that a particular fasting interval eliminates risk. When researching the issue, check whether a statement describes an observed event, a physiological measurement or an actual procedural outcome. They do not all establish the same thing.

Prepare a short handoff note
Write down the exact medicine, prescribing clinic, most recent administration, recent prescription changes and symptoms such as persistent nausea or vomiting. Include whether the medicine is being used for diabetes or another condition so the team can consider what interruption would mean. A useful handoff does not need an essay: accurate dates and a contact for the prescriber are more valuable than a general statement that you use an injection for weight loss.

Let the team choose the precautions
Depending on the circumstances, the anesthesia team may use dietary instructions, assessment of stomach contents, a modified anesthesia plan or postponement. ASA describes these as individualized options. Do not invent your own fasting or medication-withholding schedule from a checklist online. Ask who will issue the final instructions and how any change will be communicated to the surgeon, anesthesiologist and prescriber. Coordinated instructions reduce the chance of receiving incompatible advice.[2]
Remember procedures outside an operating room
A scheduling form may use words such as sedation rather than anesthesia. Ask what type of sedation is planned and which team is responsible for the medication review. Bring the prescription list to endoscopy and other procedural appointments as well. The practical question is whether the medicine has been considered in the actual plan, not whether the appointment feels like major surgery. Confirm instructions again if the procedure date or planned sedation changes.[1]
Plan the follow-up before the appointment
Ask whom to contact about resuming the prescribed routine if the team changes it, and what to do if the procedure is delayed. A cancellation can leave patients with instructions intended for a date that no longer applies. Keep the updated directions with the medication list and share them with the prescriber. A provider comparison can help assess communication access, but it cannot supply anesthesia instructions for an individual procedure. Related reading: questions about provider follow-up.
