♦ Cardiovascular and microvascular
complications of type 2 diabetes begin prior to

its clinical diagnosis
♦ Monotherapy fails in the majority of patients
with type 2 diabetes

♦ Effective treatment strategies should include
reduction in A1C, blood pressure, and

14. Recommendations for Adults
with Diabetes Mellitus
• Goals should be individualized
• Certain populations (children, pregnant females,
elderly) require special considerations
• Set less intensive goals in patients with severe or
frequent hypoglycemia (especially if ‘hypoglycemia
q yp g y ( p y yp g y
unawareness’ is present.)
• More stringent goals (i.e. a normal A1C ≤6.0-6.5%)
6.0 6.5%)
may further reduce microvascular outcomes (renal),
but do not effect macrovascular outcomes
(ACCORD, ADVANCE, VADT).
