Euglycemic Diabetic Ketoacidosis With Sodium-Glucose Cotransporter-2 Inhibitor Use Post-Bariatric Surgery: A Brief Review of the Literature.

Sodium-glucose cotransporter-2 (SGLT-2) inhibitors are antihyperglycemic drugs that are currently being recommended as second-line therapy for patients with diabetes mellitus. SGLT-2 Inhibitors function by inhibiting renal cotransporters, which reduces the reabsorption of glucose in the kidney, ultimately decreasing the concentration of glucose in the body. They have gained popularity in recent years due to their protective effects on the heart and kidneys - both organ systems that diabetes mellitus has shown to have a deleterious effect on. However, despite their growing fame, they have been found to increase the risk of euglycemic diabetic ketoacidosis (DKA). Euglycemic DKA is particularly dangerous as there is a chance that it can be missed by clinicians due to glucose levels generally being less than 200 mg/dL. There is an increasing body of literature detailing cases of euglycemic DKA after bariatric surgery. We present a brief review of the literature regarding this important side effect of SGLT-2 inhibitors seen in patients after bariatric surgery.
