The normal value of blood glucose 2 hours after a meal is less than 7.8 mmol/L for normal people. The 2-hour postprandial blood glucose, i.e. the blood glucose value measured 2 hours after eating, is a commonly used indicator for monitoring blood glucose control. The normal value of postprandial blood glucose is less than 7.8mmol/L. If the 2-hour postprandial blood glucose level is in this range, it can basically be regarded as a relatively normal blood glucose level; if the postprandial blood glucose value is between 7.8mmol/L-11.1mmol/L, it may be an abnormality of glucose tolerance or high blood glucose, so it is necessary to pay attention to it; if the 2-hour postprandial blood glucose level is more than 11.1mmol/L, most patients can be regarded as diabetic. , most patients can be considered diabetic. A 2-hour postprandial blood glucose easily detects possible postprandial hyperglycemia levels. Many patients with type 2 diabetes do not have high fasting blood glucose, but have high postprandial blood glucose, which is often delayed if only fasting blood glucose is checked. The 2-hour postprandial blood glucose value can also better reflect the diet and medication is not appropriate, according to the 2-hour postprandial blood glucose level to adjust the diet and medication.
