A fasting blood glucose of 6.35mmol/L is generally considered impaired fasting glucose regulation; a 2-hour postprandial blood glucose or random blood glucose of 6.35mmol/L is generally considered normal. Fasting blood glucose is 3.9-6.1mmol/L in normal people. If fasting blood glucose of 6.35mmol/L is measured, fasting blood glucose regulation is impaired and there is a risk of further development of diabetes mellitus. Dietary control is recommended to avoid high sugar content foods such as desserts and milk tea, and to increase exercise and weight loss to regulate blood glucose levels. If the 2-hour postprandial blood glucose or random blood glucose is 6.35mmol/L, it is generally within the normal range and does not require special treatment. It is recommended to consult a doctor for treatment when abnormal elevation of blood glucose occurs.
