GLP-1 receptor agonists delay gastric emptying, increasing the risk of pulmonary aspiration during anesthesia, necessitating specific perioperative holding periods or gastric assessment before elective surgery.

If you are taking a GLP-1 weight loss drug (like Ozempic or Wegovy) and need elective surgery, tell your surgeon and anesthesiologist immediately. These drugs slow down your stomach, which can cause dangerous aspiration during anesthesia. You may need to hold your medication for 1-3 weeks before surgery, or your surgery might be postponed until your stomach is empty. Do not skip doses without consulting your care team, as this can affect your blood sugar and weight management.

Increased attention has been turned to the safety of this class of medications in the perioperative period due to concerns of increased risk of aspiration due to delayed gastric emptying... The authors found residual gastric contents in 8 (24.2%) patients on semaglutide and 19 (5.1%) not taking semaglutide (P < .001).
