At present, diabetes has become a big killer of human health, which is second only to cancer. In fact, diabetes itself is not terrible. What is terrible is the complication of diabetes. Almost all the harm caused by diabetes comes from its complications. In China, there are 6,543.8+0.2 million diabetic patients, 5 million stroke patients, 6 million coronary heart disease patients, 450,000 blind patients and 500,000 uremia patients. Therefore, patients should persist in long-term treatment, establish confidence and determination to overcome the disease, overcome the mental factors that are not conducive to the cure of diabetes, control the development of diabetes and prevent complications under the guidance of doctors and close cooperation with themselves.
