Postprandial blood glucose generally refers to two-hour postprandial blood glucose. For undiagnosed people, a two-hour postprandial glucose of 8.3 mmol/L is abnormal and high, but for diabetic patients it is normal and is considered to be in compliance with glucose control standards. If you are referring to blood glucose at other points in time, it depends on the situation. Normal 2-hour postprandial blood glucose less than 7.8mmol / L, 7.8 ~ 11.0mmol / L belongs to the abnormal glucose tolerance, more than 11.1mmol / L at the same time there are “three more and one less” clinical symptoms, can be diagnosed as diabetes. The 2-hour postprandial blood glucose is 8.3mmol/L, it is recommended to improve the fasting blood glucose, glycated hemoglobin and other related examinations. For diabetic patients, the goal of glycemic control is generally in the fasting blood glucose 4.4mmol/L ~ 7.0mmol/L, non-fasting blood glucose does not exceed 10.0mmol/L. Therefore, the postprandial blood glucose 8.3mmol/L is normal. Postprandial blood sugar 8.3mmol/L, it is recommended to consult a doctor in time, under the guidance of the doctor to clarify the condition.
