Glucose 9.59 generally refers to venous blood glucose 9.59mmol/L. It is also necessary to distinguish between fasting blood glucose and postprandial blood glucose according to the timing of the blood draw. If the fasting blood glucose 9.59mmol / L, at the same time appeared “three more and one less” diabetes symptoms, can be diagnosed with diabetes; if it is two hours after the meal blood glucose 9.59mmol / L, suggests that impaired glucose tolerance, but also need to improve other related checks. 1. Fasting blood glucose: fasting blood glucose 3.9-6.1mmol/L is normal, 6.1-6.9mmol/L is impaired fasting blood glucose regulation, ≥7.0mmol/L with diabetic symptoms can be diagnosed as diabetes mellitus, therefore, if the fasting blood glucose 9.59mmol/L is suggestive of diabetes mellitus diagnosis. 2. Two-hour postprandial blood glucose: normal people’s two-hour postprandial blood glucose <7.8mmol/L, 7.8~11.1mmol/L for impaired glucose tolerance, ≥11.1mmol/L with diabetic symptoms can be diagnosed as diabetes mellitus. Therefore, if the two-hour postprandial glucose is 9.59mmol/L, it suggests that glucose tolerance is abnormal, and the oral glucose tolerance test and other related examinations should be improved. Therefore, glucose 9.59mmol/L should actively consult the doctor to clarify the diagnosis, and follow the doctor's instructions for treatment.
