Categories of glycemia as indicated by fasting plasma glucose levels and 75 g OGTT results. *1 The impaired fasting glucose (IFG) category refers to individuals with fasting plasma glucose (FPG) levels of 110–125 mg/dL and 2‐h plasma glucose (PG) levels of <140 mg/dL in a 75 g OGTT (WHO), with the caveat, however, that IFG is defined as an FPG 100–125 mg/dL and only FPG is used in the diagnosis of IFG in the American Diabetes Association criteria. *2 Individuals with FPG 100–109 mg/dL are defined as the normal high FPG sub‐category as part of the normal FPG category. It is advisable to perform OGTTs in this population who are shown to be quite heterogeneous in their susceptibility to diabetes or the severity of IGT confirmed at OGTT. *3 As one of the definitions included in the diagnostic criteria proposed by the WHO, IGT is diagnosed in individuals with FPG <126 mg/dL or 2‐h 75 g OGTT PG ranging between 140 and 199 mg/dL.
