29.1 Million Americans Now Have Diabetes

The CDC reports an increasing number of Americans are diabetic

About 29.1 million Americans—nearly 10% of the U.S. population—now has type 2 diabetes, according to a new report.

Of those Americans with the illness, 27.8% of them are undiagnosed, according to the U.S. Centers of Disease Control and Prevention’s 2014 National Diabetes Statistics Report released Tuesday. The report uses data collected between 2009-2012, as well as national surveys.

The CDC estimates that the direct and indirect costs of the disease have reached $245 billion, with direct medical costs making up 72% of that amount. People with type 2 diabetes incur medical costs on average 2.3 times higher than people without the disease, the CDC found.

Type 2 diabetes is caused by various factors that result in a heightened amount of blood sugar in the body. The disease is divided into two types; type 1 diabetics do not produce enough insulin, a hormone integral to metabolizing blood sugars, while in type 2, the body cannot use the insulin it makes. Diabetes can in the most severe cases result in serious complications including heart and kidney disease.
