The normal range of fasting blood glucose for people aged 60-70 years is 3.9-6.1 mmol/L, and the normal 2-hour postprandial blood glucose should be less than 7.8 mmol/L. A person’s blood sugar is not fixed, but changes with the body’s dietary status. Generally speaking, to determine whether the blood sugar is normal or not, we mainly check the blood sugar value in two periods, one is fasting blood sugar, and the other is 2 hours after meal blood sugar. The so-called fasting blood glucose refers to the blood glucose value measured when the body has not eaten food containing calories for at least 8 hours, while the 2-hour postprandial blood glucose refers to the blood glucose value measured when the blood glucose test is conducted 2 hours after the first bite of the meal. For people aged 60-70 years old, the normal blood glucose value standard is the same as that of ordinary adults, i.e., fasting blood glucose is 3.9~6.1mmol/L, and 2 hours postprandial blood glucose is less than 7.8mmol/L. If abnormal blood glucose is detected, it is recommended to consult a doctor in time and follow the doctor’s instructions for examination and treatment to avoid delaying the condition.
