”Diabetes? How early do I have to get it?” “I’m in good health, I can’t have diabetes.” Whenever doctors talk to people about diabetes, they always hear similar responses. But statistics show that the number of people with diabetes in China is rapidly increasing. Is diabetes still the “disease of the rich” that only a few rich people used to have? Is it really far from you? In fact, diabetes has been a common disease for nearly 20 years. Since the first epidemiological survey of diabetes in China in 1980, the prevalence of diabetes has increased from less than 1% at that time to about 10%, becoming the third most serious chronic disease threatening people’s health after tumors and cardiovascular diseases. China’s population is susceptible to diabetes, and with the increase in aging, improvement in living standards and the increase in obesity due to poor lifestyles, the situation of diabetes prevention and treatment in China is becoming increasingly serious. According to the recent survey results, it is estimated that the number of diabetes patients in China’s rural areas is 43 million, and the number of diabetes patients in urban areas is 49 million. The number of people with diabetes in China has doubled the number of people predicted by the International Diabetes Federation in 2025. And in five years, the number of people with hyperglycemia (diabetes plus impaired glucose tolerance) in China will perhaps exceed 100 million.
