When diabetes is first discovered, the blood glucose level in the body is relatively high, and many organs in the body, especially the brain, have already adapted to the high blood glucose state, after the hypoglycemia treatment, there may be a significant drop in blood glucose, which will produce discomfort. In particular, there may be similar reactions to hypoglycemia, such as dizziness, nausea, cold sweat, panic, hand trembling and other symptoms. Therefore, when long-term hyperglycemic diabetic patients are undergoing hypoglycemic treatment, the speed of blood sugar decline should not be too fast to avoid various uncomfortable feelings.
