GLP-1 before surgery, sedation, endoscopy or dental work: what to tell the anesthesia team
Written by an anesthesiologist: the point is not to decide for your team, it is to give them what they need to decide well.
Tell the procedural and anesthesia teams that you use a GLP-1 medicine as soon as a procedure is being planned. Include the exact product, dose, last administration, recent dose changes, and digestive symptoms. These medicines can delay stomach emptying; retained stomach contents matter during anesthesia or deep sedation.
Current multisociety guidance does not say that every patient must stop every GLP-1 medicine for a fixed period. Many patients can continue treatment. Risk assessment includes factors such as dose escalation, significant digestive symptoms, and other conditions affecting stomach emptying. In selected cases, the team may advise a liquid-only diet for 24 hours, modify the anesthesia plan, or delay a procedure.

Tell your care team about all medicines and supplements, a planned pregnancy, breastfeeding, a history of pancreatitis or gallbladder problems, major stomach-emptying problems, diabetic eye disease, and any planned procedure involving anesthesia or deep sedation. Semaglutide and tirzepatide products carry a boxed warning concerning thyroid C-cell tumors seen in rodents and contraindications involving a personal or family history of medullary thyroid carcinoma or MEN2. Those are specific conditions, not a general statement that every thyroid diagnosis rules out treatment.
If you take insulin or a sulfonylurea, arrange a blood sugar plan before treatment changes. The combination can increase hypoglycemia risk. Do not reduce insulin yourself; do not assume low blood sugar is impossible without it. Chapter 3 explains what to do.
