Everyone's blood sugar must be within the normal range to be healthy. But now many people will find that blood sugar has risen because they don't control their diet.

Normal blood glucose: 3.9-6. 1 mmol/L on an empty stomach. It is between 3.9 and 7.8 mmol/L two hours after meals. If the fasting blood sugar exceeds 7 mmol/L or the blood sugar exceeds11.1mmol/L two hours after meals, it can be judged as diabetes.

If the fasting blood glucose exceeds 6. 1 mmol/L, but does not reach 7 mmol/L, and the blood glucose exceeds 7.8 mmol/L two hours after meals, but does not reach1.1mmol/L, it belongs to pre-diabetes.

If it is only pre-diabetes, it can be adjusted by controlling diet and exercise. If necessary, take drug-assisted treatment. Therefore, once you find blood sugar and abnormal blood sugar, you should seek medical advice in time. If you are in pre-diabetes, you can consult a professional doctor to adjust your diet to avoid developing diabetes.
