Diabetes is a group of diseases characterized by high levels of blood glucose (or blood sugar) which results from problems with insulin production, insulin action, or both.
Diabetes can lead to serious problems and complications, such as heart disease, blindness, kidney failure, lower-limb amputations, and premature death.
The prevalence of type 2 diabetes is increasing in epidemic proportions throughout the U.S. and the world.
17.9 million Americans have been diagnosed with diabetes and another 5.7 million are undiagnosed—for a total of almost 24 million Americans with diabetes.
