Inadequacies of absolute threshold levels for diagnosing prediabetes

Abstract

Prediabetes comprising Impaired Fasting Glucose (IFG) and Impaired Glucose Tolerance (IGT) represents an intermediate stage of altered glucose metabolism between normal glucose levels and type 2 diabetes mellitus and is associated with an increased risk for the development of diabetes and cardiovascular disease. There is considerable evidence that glucose levels lower than those meeting the current definition of prediabetes may also be associated with similar risks particularly in high-risk individuals. Prediabetes is often unrecognized and therefore constitutes a major public health concern suggesting the need for earlier intervention than is currently recommended.
