Prevalence of Total, Diagnosed, and Undiagnosed Diabetes Among Adults: United States, 2013-2016.

Diabetes is a major cause of morbidity and mortality in the United States (1-3). Diabetes can be present but undiagnosed, meaning that a person can have diabetes but not report having ever been told by a doctor or health professional that they have the condition. Type 2 diabetes can progress over an extended time period with gradual, often unnoticed, changes occurring before diagnosis. If left unmanaged, diabetes may contribute to serious health outcomes including neuropathy, nephropathy, retinopathy, coronary artery disease, stroke, and peripheral vascular disease (4). This report presents the prevalence of total, diagnosed, and undiagnosed diabetes in U.S. adults in 2013-2016.
