Beyond the Benefits: A Case Study on the Complications of Sodium-Glucose Co-Transporter-2 (SGLT2) Inhibitors (Euglycemic Diabetic Ketoacidosis (DKA) and Takotsubo Cardiomyopathy)

Abstract

Sodium-glucose co-transporter-2 (SGLT2) inhibitors, integral in type 2 diabetes mellitus (T2DM) management, are not without risks, with reported adverse effects including euglycemic diabetic ketoacidosis (EDKA). We present a case of a 75-year-old female with T2DM on canagliflozin, who developed altered mental status (AMS), nausea, vomiting, and hypotension. The laboratory results revealed ketoacidosis, elevated troponins, and Takotsubo cardiomyopathy (TC), prompting the cessation of canagliflozin. This paradoxical EDKA case underscores the necessity for cautious prescribing. Additionally, our discussion delves into the risk factors, mechanisms, and epidemiology of EDKA associated with SGLT2 inhibitors (SGLT2i), emphasizing the importance of individualized medicine and shared decision-making in their use, despite their proven cardiovascular benefits.
