Patient's question:
Doctor, I went to the hospital with my friend today for a thorough examination. My friend is only 36 years old. I asked the doctor what was wrong with my friend. The doctor said that it is currently showing signs of spreading towards the "evening phenomenon" of diabetes. What is the "evening phenomenon" of diabetes?Doctor's answer:
That is, the high blood sugar that reappears in the evening in diabetes is called the "sundown phenomenon." This most often occurs before dinner, when the blood sugar is higher than it was two hours after lunch—between 1 and 3 millimoles per liter. In fact, this phenomenon is not uncommon. Generally, the human body has blood sugar peaks in the early morning and afternoon. Normal people can keep their blood sugar levels stable at all times, but diabetics cannot. This is because diabetics have fewer or dysfunctional basal insulin. As a result, their blood sugar is higher during these two periods. The additional periods are called the "dawn phenomenon" and the "sundown phenomenon." Some patients have a more specific condition where high blood sugar occurs again before bed. This high blood sugar is due to the insulin deficiency in diabetics, as they have less insulin, making it difficult to control blood sugar.
