A 4-hour postprandial blood glucose of 7.6 mmol/L may be abnormal.
Normally, 4-hour postprandial blood glucose level will return to the fasting blood glucose level, i.e., 3.9-6.1mmol/L. However, 4-hour postprandial blood glucose is not a diagnostic criterion for diabetes, and it is mostly recognized as random blood glucose. It is recommended to take intravenous fasting blood glucose and 2-hour postprandial blood glucose measurements under the guidance of a doctor to determine whether there is an increase in blood glucose.
If there are diabetes typical “three more and one less” symptoms (drinking, urinating, eating, wasting), to meet the fasting blood glucose 7 ≥ mmol / l, or 2 hours after the meal blood glucose ≥ 11.1 mmol / l, or random blood glucose ≥ 11.1 mmol / l, or glycated hemoglobin ≥ 6.5% can be diagnosed as diabetes.
If there are no symptoms of diabetes, two plasma glucose events meeting these criteria are required to confirm the diagnosis.
It is recommended to consult a doctor for a clear diagnosis and early treatment under the guidance of a doctor when abnormal blood glucose or physical discomfort occurs.
