Effect of Farxiga on Renal Function and Size in Type 2 Diabetic Patients With Hyperfiltration

Summary

The investigators propose to treat newly diagnosed, hyperfiltering T2DM patients with or without microalbuminuria with dapagliflozin or metformin for 4 months. The metformin-treated group will serve as controls for improved glycemic control, since the investigators have shown that insulin therapy to normalize A1c reduces hyperfiltration and kidney size in T1DM patients.
