Prediabetes as a Therapeutic Target

The term "prediabetes" is used to describe a condition that involves impaired glucose tolerance (IGT) or impaired fasting glucose (IFG). IGT is defined by a 2-h oral glucose tolerance test plasma glucose concentration >140 mg/dL (7.8 mmol/L) but <200 mg/dL (11.1 mmol/L), and IFG is defined by a fasting plasma glucose concentration ≥100 mg/dL (5.6 mmol/L), but <126 mg/dL (7.0 mmol/L). Studies have shown that people with prediabetes tend to develop type 2 diabetes within 10 years and are at increased risk for cardiovascular disease and death even before the development of diabetes.
