A 2-hour postprandial blood glucose of 4.6 mmol/L is within the target range and normal for both normal people and people with diabetes. 1. The normal value of 2-hour postprandial blood glucose for normal people is below 7.8 mmol/L, so 2-hour postprandial blood glucose 4.6 mmol/L is normal. 2. For patients who have been diagnosed with diabetes in the past, the 2-hour postprandial blood glucose should be controlled below 10mmol/L, so the 2-hour postprandial blood glucose of 4.6mmol/L has reached the control target, and the current treatment program can be continued. Attention should be paid to regular monitoring of blood glucose, and if symptoms of hypoglycemia such as panic, hand tremor and hunger occur, the doctor should be consulted to adjust the treatment plan. If abnormal blood glucose level is found, it is recommended to go to the endocrinology department as soon as possible, complete the relevant examinations under the guidance of the doctor, clarify the condition, and then follow the doctor’s instructions for treatment, so as to avoid delays in the condition, which may lead to serious consequences.
