Why Bother to Treat Agressively?
One third of adults with diabetes are undiagnosed ~10% of US adults have diabetes/~20 million persons in 2005 Nearly one third don’t know they have diabetes 26% of US adults have impaired fasting glucose (IFG)* *100–125 mg/dL Cowie CC et al.

Each of the increments of mean glucose level is subdivided into four quartiles of glycemic variability. Q1 represents the lowest quartile; Q4 represents the highest quartile Glucose Variability as a predictor of mortality within different ranges of mean glucose Higher sugars/ higher Variability Higher the Mortality Hermanides, Critical Care Med,38:838, 2010
