SGLT2i in Patients with Type 1 Diabetes: Benefits, Risks, and Preventive Strategies

Abstract

Sodium-glucose cotransporter inhibitors (SGLT2i) play an increasingly important role in type 2 diabetes mellitus (T2DM) due to their significant cardiovascular benefits and renal protection in addition to their hypoglycemic effects. In recent years, the application of SGLT2i in patients with type 1 diabetes mellitus (T1DM) has attracted more and more attention. Studies have shown that SGLT2i improves glycemic control, reduces total daily insulin dose, decrease body weight in patients with T1DM, without increasing the risk of severe hypoglycemia. SGLT2i also reduces urinary protein levels, prevents atherosclerosis, and offers cardiorenal benefits in patients with T1DM. But simultaneously, they significantly increased risk of diabetic ketoacidosis (DKA), which leads to increased hospitalization and mortality. Hence SGLT2i is recommended to T1DM who are motivated, adhere to self-glucose monitoring, well-trained in identifying DKA, and closely followed to ensure the efficacy and safety.
