Clinically, there is no such thing as mild diabetes, but it can be described as pre-diabetic changes due to changes in blood glucose values, such as abnormal glucose tolerance and impaired fasting glucose. Pre-diabetic changes can be characterized by thirst, excessive drinking, excessive urination, weight loss, etc. The normal blood glucose value is 3.9-6.1 mmol/L for fasting and less than 7.8 mmol/L for 2 hours after meal. And when fasting blood glucose is greater than or equal to 6.1mmol/L but less than 7.0mmol/L and 2-hour post glycemic load blood glucose is less than 7.8mmol/L, it suggests impaired fasting blood glucose. When fasting blood glucose is less than 7.0 mmol/L but 2-hour post glycemic load blood glucose is greater than or equal to 7.8 mmol/L less than 11.1 mmol/L, it suggests impaired glucose tolerance. Mild abnormalities in blood glucose can be adjusted through physical exercise, weight loss, dietary adjustments, and monitoring of blood glucose, etc. If blood glucose still cannot be controlled within the normal range, you should go to the hospital in a timely manner, and adjust your blood glucose treatment under the guidance of your physician.
