Impaired Fasting Glucose & Impaired Glucose Tolerance

Key points

• Impaired fasting glucose and impaired glucose tolerance There are two main types of IGR:
• impaired fasting glucose (IFG) - due to hepatic insulin resistance
• impaired glucose tolerance (IGT) - due to muscle insulin resistance
• patients with IGT are more likely to develop T2DM and cardiovascular disease than patients with IFG Definitions
• a fasting glucose greater than or equal to 6.1 but less than 7.0 mmol/1 implies impaired fasting glucose (IFG)
