Insulin works mainly by lowering blood sugar and regulating it.
Insulin is a protein hormone secreted by pancreatic islet B cells and is the only hormone in the human body that lowers blood sugar. It is mainly through the binding of insulin to specific receptors on the membrane of target cells, prompting the cells to transport insulin to achieve the effect of lowering blood sugar and regulating blood sugar.
It is worth noting that insulin is mainly used for patients with type 1 diabetes mellitus, some patients with type 2 diabetes mellitus with poor oral drug effects and poor pancreatic islet function, as well as patients with gestational diabetes mellitus, or various acute and chronic complications. During the use of insulin can occur some adverse reactions, such as edema, hypoglycemia, subcutaneous hardness. It is forbidden to use it for patients with hypoglycemia and insulin allergy.
Insulin belongs to prescription drugs, need to be used under the guidance of a doctor, not blindly self-use.
