Prevalence
Prediabetes is a condition defined by the presence of impaired fasting glucose (IFG) and/or impaired glucose tolerance (IGT) that has not yet reached the threshold for type 2 diabetes mellitus (T2D); the metabolic syndrome is also considered a prediabetes equivalent (1,2). Prediabetes raises short-term absolute risk of T2D by 3- to 10-fold (2). In the United States, 86 million people, or 37% of the US population, have prediabetes, and it is estimated that up to 70% of people with prediabetes may develop T2D during their lifetimes (3,4).
