In recent years, with the continuous development of medical and health services, the prevalence of diabetes has gradually increased on the basis of the improvement of people’s living standards and the extension of their life span. According to reports in the literature, the prevalence rate in the United States is 5%, and that in Western Europe is 2.4%. In 1978, the prevalence of diabetes survey among 100,000 people in Shanghai was 10.12%. The early symptoms of this disease are often not obvious, easily overlooked or misdiagnosed.
