How Many Americans Have Diabetes?

by Wellness Letter  

More than 110 million U.S. adults now have diabetes or prediabetes, according to a CDC report. Of the 30 million American adults with diabetes, it’s estimated that anywhere from 11 to 24 percent of cases are undiagnosed. About 95 percent of all cases are type 2 diabetes, the rest type 1 (previously known as juvenile diabetes).

Of the 80 million adults (about one-third of the adult population) who have prediabetes, only about one in ten know it. Prediabetes, characterized by moderately elevated levels of blood sugar, often progresses to type 2 diabetes, though this may be prevented by diet, exercise, and loss of excess body weight.

A version of this article first appeared in the UC Berkeley Wellness Letter.
