The use of the glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) receptor agonist tirzepatide has markedly increased for the treatment of weight loss and management of diabetes mellitus. Gastrointestinal adverse effects of GLP-1/GIP agonist therapy, including nausea, vomiting, and constipation, are common. We report a case of colonic ischemia in a 62-year-old woman which developed in association with the use of tirzepatide for weight loss. This report highlights a potential risk relationship between GLP-1/GIP agonist therapy and colonic ischemia and identifies risk factors that should be considered before prescribing tirzepatide.
Keywords: colonic ischemia; glucagon-like peptide-1 receptor agonists; tirzepatide.
