With the development of China’s economy, the improvement of people’s living conditions, and the enhancement of health care awareness, longevity is no longer an unattainable dream for most people. type 2 diabetes patients often ask us the question: “Can we live a long life? “. The answer is yes. In today’s society, people are over-nourished, physically active and many other reasons cause the incidence of diabetes, hypertension, hyperlipidemia, cerebral infarction, coronary heart disease, obesity and other chronic diseases to rise year by year, and many patients die from cardiovascular and cerebrovascular accidents due to low diagnosis rate, low treatment rate and low attainment rate. The treatment of type 2 diabetes requires a comprehensive standard, i.e. reasonable diet, strengthening exercise, weight control, smoking cessation, control of blood glucose, blood pressure and blood lipids, which is equivalent to the intervention of several cardiovascular and cerebrovascular risk factors, which can greatly reduce the occurrence of acute and chronic cardiovascular and cerebrovascular accidents, prolong the life span of patients and improve their quality of life in their later years. Therefore, it is reasonable to believe that patients with type 2 diabetes can live longer than those without diabetes if they have ideal control.
