Medical explanation: Diabetic patients mainly do not have enough insulin. type 1 diabetes is due to the destruction of the insulin manufacturing “factory”; type 2 diabetes is a serious decline in insulin efficiency, the original work of one insulin molecule now requires a hundred insulin molecules to complete, exceeding the “factory” production capacity. The production capacity of the “factory” is exceeded, so there is not enough insulin to use. Therefore, for diabetic patients, insulin supplementation is one of the most direct and effective treatment methods. There are several cases where it is still necessary to use it, one is suffering from type 1 diabetes; one is when oral hypoglycemic drugs cannot effectively control blood sugar; one is when serious chronic complications have occurred, and using insulin will be more beneficial to the condition than using oral drugs. In addition, if there is a need for surgery, large trauma and serious infection, it is also necessary to treat with insulin. When the wound heals and the infection is cured, the patient can still choose oral hypoglycemic drugs again. Doctors remind: insulin can be said to be the most powerful weapon to control blood sugar and has nothing to do with “addiction”. The use of insulin should not be a burden to the mind.
