Insulin and high blood sugar.

Insulin is a protein hormone that lowers blood sugar. Under normal circumstances, after insulin injection, blood sugar is relatively easy to control. If the diabetic patient's blood sugar is still high after insulin injection, the first thing to consider is his own diet and exercise. If he does not pay attention to diet during insulin injection, does not take proper physical exercise, and changes his exercise habits before insulin injection, it may cause blood sugar to rise. Another reason is that the insulin injection dose may not be enough. The insulin injection dose should be flexibly selected according to the patient's blood sugar situation. It generally takes 3 to 5 days to adjust the insulin dose, and it may also show some insulin antibodies, which are often seen in patients who inject insulin for a long time and produce insulin resistance.
