Managing glucose in T2DM • Diabetes is a progressive disease • Most patients will require multiple therapies to achieve A1C goals • Utilize lifestyle intervention and metformin as initial treatment • Add medications rapidly and transition to new agents when A1C target is not achieved/sustained • Add insulin early in patients who do not meet A1C targets Nathan DM et al.
