Lay Description

In this study, the researchers hope to learn about SGLT2 inhibition on EGP (endogenous glucose production) and plasma glucose concentration in diabetic subjects. Researchers will examine diabetes and the role of increased plasma glucagon, decline in plasma insulin, and fall in plasma glucose concentration.
