The 2017 Chinese Diabetes Control Guidelines for Type II diabetes include a fasting blood glucose target of 4.4-7.0 mmol/L or less for comprehensive control. The fasting blood glucose control target will be adjusted under special circumstances. Among them, fasting blood glucose should be controlled below 7.0mmol/L for children and adolescents with diabetes and below 5.3mmol/L for all types of diabetes during pregnancy. For elderly diabetic patients over 65 years old, the fasting blood glucose control target should be appropriately relaxed according to their health status, life expectancy and whether their daily behavioral ability is impaired. Patients with severe infections or cardiovascular diseases should also have their fasting blood glucose targets adjusted accordingly.
