Due to the current state of medicine, diabetes is still a chronic disease that is not curable and therefore requires continuous medical care. From a biomedical perspective, the goal of diabetes treatment is to prevent acute complications and reduce the risk of chronic complications by correcting the poor lifestyle and metabolic disorders of diabetic patients. However, in the management of diabetes, improving the quality of life and maintaining good psychological status of the diabetic patient are also important therapeutic goals of diabetes. Therefore, the patient is a key member of the diabetes management team and any treatment plan should be implemented taking into account the individual requirements of the patient and not neglecting the family and other psychological factors of the patient. The treatment of diabetes should be comprehensive. The first level of “comprehensive” means that the treatment of diabetes includes diet control, exercise, blood glucose monitoring, diabetes self-management education, and medication. The second level of “comprehensive” means that although diabetes is mainly diagnosed by hyperglycemia and therefore requires medical care, for most people with type 2 diabetes, it is often accompanied by other manifestations of the “metabolic syndrome”, such as hypertension and dyslipidemia. Therefore, the treatment of diabetes mellitus should be a combination of glucose-lowering, blood pressure-lowering, lipid-regulation and changes in lifestyle habits such as smoking cessation. The goals of diabetes control are shown in the table.
