Fasting blood glucose of 3.9-6.1 mmol/L is normal for 60-year-old patients without diabetes. If diabetes is present, the normal fasting blood glucose standard for 60-year-old patients should be based on the duration of diabetes, co-morbidities, and risk of hypoglycemia. Fasting blood glucose standards for 60-year-old patients are based on normal adult fasting blood glucose, i.e., fasting blood glucose of 3.9~6.1mmol/L is normal. In the case of diabetic patients, the 60-year-old fasting blood glucose normal values are determined and categorized as follows: 1. 60-year-old people without cardiovascular disease, diabetes duration is relatively short, it is recommended that strict control, fasting blood glucose 4.4 ~ 6.1mmol / L. In high-risk groups with stable cardiovascular disease [those with 1 risk factor (i.e., family history of cardiovascular disease, hypertension, smoking, dyslipidemia, or proteinuria)], patients using glucocorticoids, patients undergoing elective surgical procedures, and critically ill patients in the surgical intensive care unit, it is recommended to have general control, with a fasting glucose of 6.1-7.8 mmol/L. In patients with severe co-morbid cardiovascular disease, long duration of diabetes or short life expectancy, loose control of fasting glucose at 7.8-10.0 mmol/L is recommended. There is no single normal standard for blood glucose in diabetic patients, and it should be evaluated according to various factors such as condition, duration of the disease, and whether there is a combination of diseases, etc. The patient should follow the doctor’s instructions to control his/her blood glucose and have it reviewed regularly.
