Diabetes mellitus is a metabolic disease characterized by hyperglycemia, and its core problem is insufficient insulin secretion and poor insulin action. Treatment of diabetes mellitus should be comprehensive, through diet, exercise, education, psychological management, etc., strict control of blood glucose, blood pressure, blood lipids and weight, and ultimately improve the quality of life of patients. Diabetes occurs when high blood glucose is caused by a combination of both insufficient insulin secretion and poor insulin action, which is its most basic pathological mechanism. The aim of diabetes treatment is to improve the survival time and quality of life of the patient. The means to do this are then at several levels: on the one hand, the treatment must be comprehensive. Why? Because there are many aspects that can lead to complications and are the main causes of eventual complications, such as blood glucose, blood pressure, blood lipids, weight, so it is necessary to do a comprehensive control. On the other hand, the means should be integrated, including in the lifestyle, such as diet, exercise, drug use, the combination of effective drugs. The third aspect is to insist on monitoring. Monitoring is very important to the treatment, without monitoring, the treatment is impossible to talk about. Diabetes is currently not curable, but blood glucose can be controlled, and the goal of all our current treatments is to control blood glucose. Since glycemic control is the goal, monitoring is very important. Of course diabetes education is also very important. Education of the patient, family, and community can improve the quality of diabetes management and ultimately the quality of life of the patient. There are many other aspects of diabetes education that require a lot of support, such as community support, government support, and support from family and friends. Psychological factors are also very important, and a lot of problems with blood glucose management can occur when psychological issues are not addressed. Therefore, the treatment of diabetes should be comprehensive, and the means should be integrated, so as to do a good job in the management of blood glucose and the control of complications, and ultimately to improve the quality of life of the patients and prolong the life of the patients.
