Glycemic control targets for diabetic patients include fasting blood glucose, 2-hour postprandial blood glucose and glycated hemoglobin. Clinically, the three should be organically combined, and overall the control goals are as follows: items good general poor fasting blood glucose 4.4-6.1 ≤ 7.0 > 7.0 non-fasting blood glucose 4.4-8.0 ≤ 10.0 > 10,0 glycated hemoglobin < 6.56.5-7.5 > 7.5 However, the blood glucose control goal of each patient varies from person to person, if there is no obvious hypoglycemia and no cardiovascular or cerebrovascular disease history, glycosylated hemoglobin should be lowered as close as possible to the level of non-diabetic patients, i.e. 6.0%, in order to provide more clinical benefit to patients. For the elderly, it is necessary to control hyperglycemia as well as to avoid serious hypoglycemia, so the glycemic target can be relaxed to 7.8 mmol/L in fasting and 11.1 mmol/L in non-fasting, and the lower limit is not less than 4.4 mmol/L. Even for those with serious cardiovascular and cerebrovascular complications, the glycemic control target can be more relaxed.
