Fasting blood glucose 7.5mmol/L will have two situations: First, fasting blood glucose 7.5mmol/L occurs under stressful situation, at this time, you can measure postprandial blood glucose and repeat re-measurement of fasting blood glucose value or other examination the next day to remove stressful factors, if the blood glucose is within the normal range without treatment; Second, if the fasting blood glucose is still around 7.5mmol/L the next day, and the blood glucose two hours after meal exceeds 11.1mmol/L, then the blood sugar is too high. After completing the relevant auxiliary examination to clearly confirm the diagnosis of diabetes, we should take a diabetic diet, and try to have a sugar-free or low-sugar diet in our daily life, and cooperate with appropriate aerobic exercise. If the blood sugar control is still not satisfactory after diet and exercise, oral or injectable hypoglycemic drugs can be taken under the guidance of the doctor. At the same time, the blood glucose level should be monitored regularly and the dosage of hypoglycemic drugs should be adjusted according to the blood glucose level.
