The normal range of blood glucose for an individual is between 3.9-6.1 mmol/L for fasting blood glucose and below 7.8 mmol/L for blood glucose two hours after a meal. Each person's physical condition differs, leading to varying blood glucose levels. Generally, under normal circumstances, the fasting blood glucose range is 3.9~6.1 mmol/L, and as long as it falls within this range, it is considered relatively normal. The blood glucose level two hours after a meal should be below 7.8 mmol/L. If fasting blood glucose exceeds 6.1 mmol/L and blood glucose two hours after a meal exceeds 7.8 mmol/L, it may indicate prediabetes or diabetes. If fasting blood glucose exceeds 7.0 mmol/L or blood glucose two hours after a meal exceeds 11.1 mmol/L, it may be diagnosed as diabetes. It is essential to manage personal diet well. If blood glucose levels are normal, there is generally no need for excessive concern, and one should consume nutritious foods. If blood glucose levels are abnormal with a significant increase, it is necessary to appropriately control sugar intake to prevent further elevation and impact on personal health recovery. Upon discovering an increase in blood glucose, one should seek medical attention promptly and follow doctor's advice for lifestyle changes and medication treatment.
