A fasting blood sugar is above 6.1mmol/L, and a blood sugar two hours after a meal is above 7.8mmol/L is considered high.

Under normal circumstances, the human body can ensure that the source and outlet of blood sugar are balanced through the two major regulatory systems of hormone regulation and neural regulation, so that blood sugar can be maintained at a certain level.

However, under the combined influence of genetic factors (such as family history of diabetes) and environmental factors (such as unreasonable diet, obesity, etc.), the two major regulatory functions are disordered, and blood sugar levels will appear. of rise.

Normal blood glucose value:

1. Normal fasting blood glucose value

1. Generally, fasting whole blood glucose is 3.9~ 6.1 mmol/L (70-110 mg/dL), and plasma blood sugar is 3.9-6.9 mmol/L (70-125 mg/dL).

2. Fasting whole blood glucose ≥6.7 mmol/L (120 mg/dL), plasma glucose ≥7.8 mmol/L (140 mg/dL), and two repeated measurements can be diagnosed as diabetes.

3. When fasting whole blood glucose is above 5.6 mmol/L (100 mg/dL) and plasma glucose is above 6.4 mmol/L (115 mg/dL), glucose tolerance should be tested test.

4. When fasting whole blood glucose exceeds 11.1 mmol/L (200 mg/dL), it means that insulin secretion is minimal or lacking. Therefore, when fasting blood glucose is significantly elevated, diabetes can be diagnosed without the need for other tests.

2. Normal blood sugar value after a meal

1. 1 hour after a meal: blood sugar 6.7-9.4 mmol/L. The maximum does not exceed 11.1mmol/L (200mg/dl).

2. 2 hours after a meal: blood sugar ≤7.8 mmol/L.

3. 3 hours after a meal: Return to normal after the third hour, and urine glucose was negative each time.
