Postprandial blood glucose generally refers to the blood glucose 2 hours after meal, which is measured from the first bite of meal and 2 hours after the blood glucose test. Postprandial blood glucose 7.3mmol/L is normal. 1. General population: the normal range of blood glucose is <7.8mmol/L 2 hours after meal, in the absence of disease, the blood glucose 7.3mmol/L 2 hours after meal is normal. 2. Pregnant women: postprandial blood glucose 7.3mmol/L for pregnant women is also normal, under normal circumstances, pregnancy If pregnant women with gestational diabetes should closely monitor their blood sugar during pregnancy, if the blood sugar is too high and unstable, it will increase the risk to the pregnant woman and the fetus, and it will easily lead to an oversized fetus, thus increasing the risk of malformed fetal development. Therefore, it is necessary to keep blood sugar at a certain level to ensure the normal operation of organs and tissues in the body, which is conducive to the healthy growth of the fetus; 3. Diabetic patients: If diabetic patients control their postprandial blood sugar at 7.3 mmol/L, it is normal, and if fasting blood sugar is also around 7.0 mmol/L, it indicates that the recent patients' blood sugar control is basically up to standard. Patients can have their glycosylated hemoglobin level tested, and if it is less than 6.3%, it indicates that the blood glucose control in the past 3 months has basically reached the standard. Diabetic patients can effectively reduce the occurrence of complications such as macroangiopathy and diabetic foot by controlling their blood sugar to the basic standard, which is very beneficial to the patients themselves.
