Diabetes is one of the most common conditions in the United States, with almost 20 million Americans living with the type 2 form of the disease. But there are many millions more people with blood sugar levels that are high, but not high enough to be classified as type 2 diabetes. This is known as prediabetes, and carries with it an increased risk of developing type 2 diabetes, heart disease, and stroke.

An estimated 41 million Americans between the ages of 40 and 74 have prediabetes according to the CDC, but its prevalence is growing in younger Americans as the obesity epidemic spreads.
