For people aged 50-60 years, if there is no diabetes in the past, the fasting blood glucose 3.9-6.1mmol/L is normal, and the 2-hour postprandial blood glucose is normal <7.8mmol/L; if there is diabetes but the underlying conditions are good, the standard of glycemic control is 4.4-7.0mmol/L for fasting blood glucose, and non-fasting blood glucose <10.0mmol/L, and the glycemic control target can be appropriately relaxed according to one's own situation. Targets. 1. For healthy people aged 50-60 years, the clinical standard range of fasting blood glucose is 3.9-6.1mmol/L, and 2-hour postprandial blood glucose is normal less than 7.8mmol/L. 2. For diabetic patients aged 50 to 60 years, if they are newly diagnosed, with short disease duration, low risk of hypoglycemia, strong self-management ability, and good treatment conditions, the glycemic control target is generally 4.4mmol/L to 7.0mmol/L in fasting glucose, and non-fasting glucose is not more than 10.0mmol/L, which can help to prevent the occurrence of complications. 3. For diabetic patients aged 50 to 60 years who are at risk of hypoglycemia, have serious complications or concomitant diseases, and have poor self-management ability, the glycemic control target should be appropriately relaxed to prevent the occurrence of hypoglycemic reactions, and at the same time, it can slow down the progression of complications, and avoid the occurrence of acute diabetic complications and refractory infections triggered by severe hyperglycemia. Diabetic patients are advised to seek medical treatment in a timely manner, and specific glycemic control standards need to be formulated comprehensively according to specific conditions.
