Fasting blood glucose of 6.6 mmol/L and 2-hour postprandial blood glucose of 14.5 mmol/L are above the normal range and need to be taken seriously. If combined with symptoms of diabetes, prompt treatment is usually required. Normally, most normal people’s fasting blood glucose is maintained at 3.9-6.1mmol/L, and 2-hour postprandial blood glucose is less than 7.8mmol/L. If you consume more sugar at one time, your blood glucose will be lower than the normal range. If a one-time intake of more sugary foods, may lead to blood glucose values over the normal value, but this phenomenon is often not lasting, and will soon return to normal. Therefore, there is no need to worry too much and targeted treatment is not required. However, when fasting blood glucose 6.6mmol/L and 2-hour postprandial blood glucose 14.5mmol/L values occur frequently, it should be taken seriously. If the 2-hour postprandial blood glucose is greater than or equal to 11.1mmol/L and there are typical symptoms of diabetes, the diagnosis of diabetes can be confirmed. It should be treated with hypoglycemic drugs as prescribed by the doctor. Common drugs include gliquidone, nateglinide, rosiglitazone, metformin and so on. Fasting 6.6mmol/L and 2-hour postprandial blood glucose 14.5mmol/L indicate that the patient may have diabetes, so he should seek medical examination as soon as possible and use medication under the guidance of the doctor.
