Fasting blood glucose 6.5mmol/L belongs to the high, need to consider through diet control, appropriate exercise to regulate; two hours after meal blood glucose 6.5mmol/L belongs to the normal range, without special treatment. Fasting blood glucose Fasting blood glucose is greater than or equal to 6.1mmol/L but less than 7.0mmol/L and 2 hours after sugar load blood glucose is less than 7.8mmol/L, suggesting impaired fasting blood glucose. Therefore, a fasting blood glucose of 6.5 mmol/L is considered high. It is necessary to combine with the 2-hour post glycemic load blood glucose to clarify whether the fasting blood glucose is impaired or not. If fasting blood glucose is impaired, it is necessary to control the total calorie intake, maintain a low-salt, low-fat, low-sugar diet, and maintain 150 minutes of aerobic exercise per week, such as running, jumping rope, playing tai chi, and so on, which can play a role in controlling blood glucose. The normal range of two-hour postprandial blood glucose should be less than 7.8mmol/L, so if the two-hour postprandial blood glucose is 6.5mmol/L, it is within the normal range and does not require any special treatment, and it is enough to maintain a healthy lifestyle. It is recommended to go to the hospital if you have abnormal blood glucose levels.
