Fasting blood glucose 5.4mmol / L, for the normal population, in the normal value of 3.9-6.1mmol / L, generally do not need to deliberately control sugar; for the diabetic population, in the range of good control 4.4-7.0mmol / L, according to the original program to continue to control sugar can be. The normal range of fasting blood glucose for normal healthy people is generally 3.9-6.1mmol/L, while fasting blood glucose 5.4mmol/L, in the range, indicating that the blood glucose level is very normal, generally do not need to deliberately control sugar. For diabetic patients, the control target fasting blood glucose level should generally be 4.4-7.0mmol/L, and fasting blood glucose 5.4mmol/L, in line with the control target, indicating that the patient’s blood glucose control is very good, and the original glucose control program is very effective, so continue with the program can be. It is recommended to consult a healthcare professional when blood glucose abnormality occurs. If there is a need to change the glycemic control program, consult a professional endocrinologist.
