Diabetes 1.5: Ketone-Prone Diabetes

Ketone-prone diabetes (KPD) is considered one of the atypical diabetes syndromes because its presentation can lead to misdiagnosis of the type of diabetes. Patients with KPD present in diabetic ketoacidosis (DKA), but once the DKA resolves, some patients can discontinue insulin and maintain adequate glycemic control with oral agents (1). Here, we present the case of a patient who was diagnosed with type 1 diabetes because of recurrent DKA. KPD was suspected because of his high insulin requirements and signs of insulin resistance. He was transitioned from insulin to a glucagon-like peptide-1 (GLP-1) receptor agonist and attained ideal glycemic control.
