In normal people, 2h postprandial blood glucose is less than 7.8 mmol/L. 2h postprandial blood glucose, either fingertip blood glucose or blood glucose measured by drawing blood, reaches 10.3 mmol/L is excessive 2h postprandial blood glucose, but in normal people, diabetic patients and pregnant women with combined diabetes, 2h postprandial blood glucose level will have certain differences. Specific differences are as follows: 1. Normal people: 2h postprandial fingertip blood glucose 10.3 mmol/L, although it does not reach the standard for diagnosing diabetes, this value is high. It is recommended to check venous blood to measure the value of 2h postprandial blood glucose or check glycated hemoglobin at the hospital. Because there may be some error in measuring postprandial blood sugar with fingertip blood, it is easy to have high value. You can also do the test of glucose tolerance to clarify whether you have diabetes; 2. Diabetic patients: 2h postprandial blood sugar 10.3mmol/L, if they are young patients, this value is high, and it is better for young patients to control 2h postprandial blood sugar at 8.5mmol/L to be safer. As for elderly diabetic patients, 10.3mmol/L is basically normal due to more complications and less exercise for patients, but it is recommended that it is better to control within 10.0mmol/L. Diabetic patients will control their blood sugar basically up to standard, which can reduce the progress of chronic complications and reduce the occurrence of acute complications; 3. Pregnant women with gestational diabetes: 2h postprandial blood sugar fingertip blood 10.3mmol/L is also a case of not very good control. Postprandial 2h blood glucose during pregnancy is recommended not to exceed 8.5mmol/L, otherwise it is easy to produce adverse effects on pregnant women or fetus. It is recommended that pregnant women follow the medical advice to adjust the treatment plan, while controlling diet and appropriate activities.
