However, their potential to delay gastric emptying has raised growing concern in perioperative care, particularly regarding the risk of pulmonary aspiration during general anesthesia. Recent studies have shown that patients treated with GLP-1 RAs may retain considerable gastric contents even after standard preoperative fasting, thereby increasing the likelihood of regurgitation and aspiration during anesthesia induction or emergence. Short-acting GLP-1 RAs cause more pronounced delays in gastric emptying, whereas long-acting agents may exert residual effects depending on dose and treatment duration. Several international anesthesia societies have issued updated guidance to mitigate these risks, yet available evidence remains limited and sometimes inconsistent. This review summarizes the pharmacological mechanisms and clinical implications of GLP-1 RA\u2013induced delayed gastric emptying, evaluates current literature on perioperative aspiration risk, and emphasizes the importance of interdisciplinary collaboration between endocrinologists and anesthesiologists to ensure safe and individualized perioperative management.<\/jats:p>","DOI":"10.3904\/kjim.2025.277","type":"journal-article","created":{"date-parts":[[2026,4,30]],"date-time":"2026-04-30T07:53:44Z","timestamp":1777535624000},"page":"384-395","update-policy":"https:\/\/doi.org\/10.3904\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Delayed
