Tirzepatide-induced ketoacidosis in non-diabetic patients

Background: Tirzepatide is a novel glucagon-like peptide 1/glucose-dependent insulinotropic peptide (GLP-1/GIP) receptor agonist. It was recently approved for diabetes control and weight reduction in non-diabetic patients. Case description: We report the first case of ketoacidosis after the use of tirzepatide in an obese non-diabetic patient, secondary to the possibility of starvation ketoacidosis and insulin resistance. Conclusion: The dual-acting GLP-1 and GIP receptor agonists, tirzepatide, can induce ketoacidosis in obese non-diabetic patients.
