Reason: The concept of fasting is that you haven't eaten for 8 hours, which is generally measured by getting up on an empty stomach in the morning. The situation you mentioned is generally caused by two reasons. First, the comprehensive blood sugar level is too high because of overeating or insufficient dosage the night before, and the diabetic has low activity at night, abnormal metabolism, and the glucose in the blood cannot be consumed, so the blood sugar level in the morning is too high, which exceeds the current definition standard of diabetes with fasting blood sugar of 5.6; Second, the low or heavy consumption of food the night before caused the symptoms of hypoglycemia at night, which led to the regulation of human metabolism, that is, the release of glycogen in the liver, which led to the high glucose content in the blood (this is the human regulation function of human evolution, and in ancient times, when animals could not get food sources for a long time, the liver released glycogen to maintain the normal glucose consumption in the blood, thus ensuring that the body would not die immediately because it could not get food calorie supplement for a long time. Therefore, carnivorous wild animals usually use the liver first after hunting live animals (because the liver is rich in glycogen), which is why doctors suggest measuring blood sugar at 3 o'clock at night to prevent the fasting blood sugar value from being too high due to hypoglycemia at night.

So the situation you described is normal. It is normal that fasting blood sugar in the morning is higher than two hours after meals the night before.

Adjustment method:

For example, if you say 2 hours and 8.9 hours after dinner, it is not up to standard. According to your situation, your mother should be young, and the blood sugar control standard is within 6. 1-8.0 two hours after dinner at night, which is the best. If it is controlled within this range, the fasting will still be high in the morning. If the blood sugar is too low at 3 pm, it will be too high in the morning because of hypoglycemia at night. In this case, you need to add meals at night. Secondly, if the blood sugar at dinner is controlled within 6. 1-8.0 two hours after the meal, the blood sugar at night is not low, but the fasting is too high in the morning, then it is necessary to increase the diet control and drug control at dinner to reduce the blood sugar at dinner to a lower and stricter standard to prevent the blood sugar from being too high in the morning;

You may sound confused, but there is nothing you can do. The abnormal glucose metabolism in diabetic patients requires long-term control and regulation to have an effect. Be patient.
