Generally, blood sugar is checked on an empty stomach and two hours after meals. The normal value of fasting blood glucose is below 6. 1 or 109 mg. Then the diagnostic standard of fasting diabetes is 7.0 or 126 mg. It can be seen that there is a gap between the normal value and the fasting diagnosis of diabetes. Some people are neither normal nor diabetic. We call this symptom fasting hyperglycemia. In addition, postprandial blood sugar is also very important. The normal value of postprandial blood glucose is below 7.8 or 140m. The diagnostic standard of diabetes is 1 1. 1 or more than 200mg. Then there is a gap between 140 and 200. If blood sugar is at this stage, we call it postprandial hyperglycemia. Not a diabetic, not normal. It is dangerous for people without diabetes to have high blood sugar and get diabetes easily. Such people must be careful. The hat hangs on his head. If you don't pay attention, you will soon wear a hat of diabetes.
Even if blood sugar is completely normal, if there are some high-risk factors, we should also pay attention to preventing diabetes.
