A blood glucose of 106mg/dl is converted to 5.89mmol/L, which is within the normal range for both postprandial and fasting blood glucose. Fasting blood glucose is usually measured before breakfast (keep at least 8~10 hours without food), the normal range of fasting blood glucose is 3.9~6.1mmol/L, and the normal range of 2 hours postprandial blood glucose is less than 7.8mmol/L, so, no matter it is the 2 hours postprandial blood glucose or the fasting blood glucose, 5.89mmol/L belongs to the normal range. In daily life, both hyperglycemic patients and healthy people should maintain a healthy lifestyle and follow a low-salt, low-fat and low-sugar diet, which will help to maintain stable blood glucose. If abnormal blood glucose value occurs, it is recommended to go to the hospital for diagnosis and timely treatment under the guidance of the doctor.
