Anti-Hyperglycemic Medication Management in the Perioperative Setting: A Review and Illustrative Case of an Adverse Effect of GLP-1 Receptor Agonist.

A host of anti-hyperglycemic agents are currently available and widely prescribed for diabetes and weight loss management. In patients undergoing surgery, use of these agents poses a clinical challenge to surgeons, anesthesiologists, and other perioperative care providers with regard to optimal timing of discontinuation and resumption of use, as well as possible effects of these agents on physiology and risk of postoperative complications. Here, we provide a comprehensive review of anti-hyperglycemic medications' effects on physiology, risks/benefits, and best practice management in the perioperative setting. Additionally, we report an illustrative case of small bowel obstruction in a patient taking semaglutide for 6 months prior to an otherwise uncomplicated laparoscopic hysterectomy and bilateral salpingo-oophorectomy. This review is meant to serve not as a replacement of, but rather as a consolidated complement to, various society guidelines regarding perioperative anti-hyperglycemic agent management.
