The main characteristics are excessive drinking, excessive urination, excessive eating, and lethargy, fatigue, and sweet urination, caused by excessive intake of fatty foods and low intake of staple foods, and it is considered to be a disease caused by behavioral problems. that is associated with sedentary and less active behavior. Diabetes is a lifelong disease, and poor control can lead to complications in multiple systems throughout the body, which can be prolonged and eventually lead to serious and life-threatening consequences. Data from the China Health Statistics Yearbook shows that direct medical costs for diabetes accounted for more than 19.9% of total national health costs this year, ranking second among all chronic diseases surveyed. Among them, 81% of diabetes-related medical expenses are spent on treating various complications, and diabetic nephropathy is the most common complication. Globally, there are now more than 200 million people with diabetes, and it is estimated that the number will exceed 300 million by 2025 and 500 million by 2030. The prevalence of diabetes among adults in China has reached 2.6% of the total population, making it the second most diabetic country in the world, second only to India. The invisible killer of diabetes is threatening the health of all human beings. Over the past 30 years, the prevalence of diabetes in China has increased significantly. The prevalence of diabetes has become more serious in the last decade. Among people over 18 years of age, the prevalence of diabetes is 4.5% in urban population and 1.8% in rural areas. The prevalence of diabetes in urban areas was 2.96%, 4.41% and 13.13% in the age groups 18-44, 45-59 and 60 years and older respectively, while in rural areas it was 195%, 0.98% and 7.78% in the corresponding age groups. The accelerated increase in the prevalence of diabetes in China is mainly related to the following factors: 1. accelerated urbanization The proportion of urban population in the national population has increased from 34% in 2000 to 43% in 2006. 2. 2. Accelerated aging The prevalence of diabetes among the elderly is over 20%, 10 times higher than the prevalence among young people aged 20 to 30. Lifestyle changes, physical activity significantly reduced, but the calorie and fat intake increased significantly, accompanied by obesity and overweight proportion shows an increase, the body mass index is seriously over the standard. 3. Increased survival of diabetic patients With the improvement of the level of control of risk factors for various complications of diabetes and the improvement of the level of treatment for complications, the risk of death from complications in diabetic patients has decreased significantly. Diabetic nephropathy is one of the most common and most serious complications of diabetes. As the prevalence of diabetes increases, so do the number of patients with diabetic nephropathy. The prevalence of type 2 diabetes complicated by nephropathy is 34.7% among hospitalized diabetic patients in China. Among the patients who started dialysis, diabetes accounted for 50%, hypertension for 27%, glomerulonephritis for 13% and others for 10%. This shows that diabetic nephropathy has become the leading cause of end-stage renal failure, accounting for 25% to 42% in the United States and Europe, and about 8% in China, growing to 15% in some economically developed regions.
