Some people mistakenly think that drinking glucose can replenish blood, but in fact it is blood sugar. When blood sugar rises rapidly, you will feel very energetic, because the brain likes sugar. However, because such high sugar enters the blood, the body has to produce more insulin to reduce blood sugar, which consumes a lot of nutrients stored in the body, and at the same time, blood sugar will drop quickly, and people will feel uncomfortable. So I went to drink glucose again, and this repeated action is almost the same as the early behavior of diabetes.
