Fasting hypoglycemia

Fasting blood glucose (GLU) refers to the blood collected before breakfast after overnight fasting (without any food for at least 8-10 hours, except drinking water), and the measured blood glucose value is the most commonly used indicator for diabetes, reflecting the islet β cells Function, generally represents the secretory function of basal insulin. The fasting blood glucose value of normal people is 3.89-5.83mmol / L; if it is greater than 5.83mmol / L and less than 7.0mmol / L, the fasting blood glucose is impaired; if it is greater than or equal to 7.0mmol / L, consider diabetes; if the blood glucose is less than 2.8mmol / L The clinically produced symptoms are called "hypoglycemia."
