Airlines, Anesthesia, and GLP-1 Drugs: Why Pre-Procedure Fasting Guidance Changed
Anesthesiology societies updated pre-procedure fasting guidance for patients on GLP-1 drugs after reports of delayed gastric emptying complicating sedation.
By the GLP Semaglutide editorial team · Last updated January 28, 2026
Anesthesiology professional societies issued updated preoperative guidance addressing GLP-1 drugs after case reports of delayed gastric emptying leading to aspiration risk during sedation, even after patients followed standard fasting instructions.
What the updated guidance generally covers
Guidance has generally focused on additional pre-procedure screening questions about GLP-1 drug use and, in some cases, extended fasting windows or temporarily pausing the medication before a scheduled procedure, based on an anesthesiologist's assessment.
This is a conversation with your care team
Anyone on a GLP-1 drug with an upcoming surgery or procedure requiring sedation should tell their surgical and anesthesia team in advance — specific fasting instructions should come from that care team, not from general guidance like this article.
