More than 29 million American adults have diabetes — up from 26 million in 2010 — yet one in four of them don’t know it, according to a report issued last Tuesday from the federal Centers for Disease Control and Prevention. Rates of both type 1 and type 2 diabetes have been increasing for years. While the obesity epidemic has been blamed on the rising rates of type 2 diabetes, the reasons for the rise in type 1 diabetes, an autoimmune condition that typically strikes in childhood, remain unknown.

CDC researchers also can’t explain why so many diabetics remain undiagnosed.

Screening should be done at a younger age in those with certain risk factors such as high blood pressure or obesity. D.K.
