INTRODUCTION: Sodium-glucose co-transporters 2 (SGLT-2) inhibitors are a relatively novel class of oral medications for the treatment of Type 2 Diabetes Mellitus, which lower plasma glucose by inhibiting glucose reabsorption in the proximal renal tubule. Apart from their hypoglycemic action, recent data suggest these agents have additional major cardioprotective and nephroprotective properties.AREAS COVERED: This review summarizes the existing data on epidemiology, pathophysiology, and treatment of euglycaemic ketoacidosis (euDKA) as a complication of SGLT-2 inhibitor use.EXPERT OPINION: Although SGLT-2 inhibitors have a relatively good adverse event profile, they have been associated with the serious and potentially life-threatening metabolic complication of euDKA. Data from major outcome trials suggest that the rate of DKA is quite low. However, the rate of DKA could be generally underestimated in clinical trials due to the atypical presentation of ketoacidosis, and even more so in real-life conditions. Management of this serious metabolic complication requires a proper understanding of its pathophysiology as well as increased awareness and early recognition of the potential risk factors involved. Following this, the institution of an array of simple supportive measures, could safely restore normal acid-base balance in most patients.
