Dr. Liu Feng
A normal person's blood glucose level may vary depending on the time of measurement. The following are common reference ranges for blood glucose:
Fasting blood glucose: refers to the blood glucose level measured before breakfast, after at least 8 to 10 hours without food. A normal fasting blood glucose level should be between 3.9 and 6.1 mmol/L.
Two-hour postprandial blood glucose: refers to the blood glucose level measured exactly two hours after the first bite of a meal. A normal two-hour postprandial blood glucose level should be less than 7.8 mmol/L.
These values apply to non-diabetic individuals. For people with diabetes, the target blood glucose range may differ and should be adjusted according to individual circumstances and medical advice. Regular blood glucose monitoring, maintaining a healthy diet, engaging in regular physical activity, and using medications when necessary are key to managing blood glucose levels. If your blood glucose levels remain abnormal, you should consult a doctor for professional guidance.
