1. Pre-diabetes refers to the development from normal glucose regulation to impaired glucose regulation (IGR), with elevated blood glucose but not yet meeting the diagnostic criteria for diabetes. It includes impaired fasting glucose (IFG) and low glucose tolerance (IGT), both of which can occur separately or in combination. (1) Impaired fasting glucose (IFG): 5.6 mmol/L ≤ fasting glucose (FPG) < 7.0 mmol/L and 2 hours postload glucose (2hPG) < 7.8 mmol/L. (2) Hypoglycemia (IGT): 7.8 mmol/L ≤ 2 hours postload glucose (2hPG) < 7.8 mmol/L. 2hPG < 11.1mmol/L and fasting blood glucose (FPG) < 7.0mmol/L. 3. General clinical symptoms of pre-diabetes are not typical, but may be manifested as obesity, abnormally high waist-hip circumference ratio and body mass index, high appetite, strong quality, but reduced endurance. Most patients are found during health checkup or examination for other diseases.
