The numbers are staggering. According to the Centers for Disease Control and Prevention, 23.5 million US adults (10.7% of people aged 20 years or older) have DM, more than 90% of which is DM2.1 In 2007 alone, 1.6 million new cases were diagnosed. Diabetes mellitus can result in heart disease, stroke, blindness, kidney disease, and amputations. Overall, the risk of death in individuals with DM is approximately twice that of individuals without DM of similar age. In 2007, estimated total direct and indirect costs related to DM in the United States were $174 billion. After adjusting for population age and sex differences, average medical expenditures among individuals with diagnosed DM were 2.3 times higher than they would have been in the absence of DM. The increase in the prevalence of DM2 is closely linked to the upsurge in obesity. Approximately 90% of DM2 is attributable to excess weight.2
