How high is high blood sugar

The level of blood glucose is an artificial factor. In 1999, the World Health Organization defined the blood glucose value of this diabetes as 7.0mmol/L or more on an empty stomach and 11.1mmol/L or more two hours after a meal. The normal blood glucose value is set at 6.1mmol/L on an empty stomach and 7.8mmol/L two hours after a meal. If it exceeds this range, it is abnormal. The fasting blood glucose is 6.1mmol/L and the blood glucose is within 7.8mmol/L two hours after a meal. Blood sugar is higher than normal. High blood sugar will cause damage to blood vessels and peripheral nerves, that is, it will show complications of diabetes. Diabetes will show complications, and pre-diabetes will also show complications. Therefore, as long as blood sugar is higher than normal range, that is, fasting above 6.1mmol/L, and two hours after meals above 7.8mmol/L, it is high blood sugar, which is abnormal.
