The standard of control for blood glucose is recommended in the guidelines in the range of 4.4-7.0 mmol/L fasting; <10 mmol/L 2 hours postprandial; and 7% glycated hemoglobin. But as with glucose-lowering regimens, we have to vary from person to person and not generalize.
1. For younger patients, those with shorter disease duration, no serious diabetic complications, and no comorbidities that affect life expectancy, because life expectancy is longer and tighter glycemic control helps delay the onset and progression of diabetic complications, tighter glycemic control is generally recommended, with fasting at about 5 mmol/L and 2-hour postprandial glycemic control at The blood glucose control should be around 8mmol/L. Glycosylated hemoglobin should be controlled at 6.5%. 2. For elderly patients or diabetic patients who have developed serious chronic complications of diabetes mellitus and combined with comorbidities that affect life expectancy, the blood glucose control is too serious and hypoglycemia may easily occur, and serious hypoglycemia may induce angina pectoris, cerebrovascular spasm, myocardial infarction, cerebral infarction and other hazards, so it is recommended that the blood glucose control is relatively lenient, fasting can be around The blood glucose can be controlled at around 8mmol/L for fasting, 10mmol/L for 2 hours after meal, and 8% for glycated hemoglobin.
