Sodium–glucose cotransporter 2 (SGLT2) inhibitors provide metabolic and cardiorenal benefits for patients with type 2 diabetes but are associated with a number of safety issues. Here, we discuss evidence suggesting that indirect activation of the FGF23–1,25-dihydroxyvitamin D–parathyroid hormone axis by SGLT2 inhibition might contribute to adverse effects on bone health.
