Blood glucose 6.29mmol/L needs to be divided into situations; two hours after meal blood glucose 6.29mmol/L is not high, fasting blood glucose 6.29mmol/L is slightly higher than normal. Fasting state generally requires at least 8~10 hours without eating any food when measured blood glucose concentration, fasting blood glucose can reflect the function of pancreatic β-cells. Normal fasting blood glucose range is 3.9~6.1mmol/L, so fasting blood glucose of 6.29mmol/L is on the high side, which may be caused by impaired fasting blood glucose regulation. Postprandial blood glucose generally refers to the concentration of blood glucose measured two hours after eating breakfast, lunch and dinner. Normal two-hour postprandial blood glucose should be less than 7.8mmol/L, so if the two-hour postprandial blood glucose is 6.29mmol/L, it belongs to the normal range and is not considered high. If you have abnormal blood glucose value, we recommend you to go to the hospital and ask the doctor to make a comprehensive judgment based on your specific situation, and you should not make a blind judgment on your own.
