Primary prevention: The primary prevention of type 2 diabetes is to prevent the occurrence of diabetes mellitus. It includes promoting knowledge of diabetes prevention and treatment among the general population, such as the definition, symptoms, signs and symptoms, common complications and risk factors of type 2 diabetes, promoting healthy behaviors, such as reasonable diet, moderate exercise, smoking cessation and alcohol restriction, and psychological balance; conducting diabetes screening among key populations, and intervening early once impaired glucose regulation (IGT and IFG) is detected, in order to reduce the incidence of diabetes.
Secondary prevention: Secondary prevention of type 2 diabetes, i.e., prevention of complications of type 2 diabetes, mainly chronic complications, in patients with diagnosed type 2 diabetes. The key to preventing complications of type 2 diabetes is to control blood glucose as early and as much as possible and to correct risk factors that lead to complications of diabetes such as hypertension, dyslipidemia, obesity and smoking. Patients with type 2 diabetes should be screened regularly for complications of type 2 diabetes and related diseases, and relevant treatment measures should be enhanced to achieve comprehensive treatment.
Tertiary prevention: Tertiary prevention of type 2 diabetes is to reduce the exacerbation of type 2 diabetes complications and reduce disability and mortality rates, and to improve the quality of life in type 2 diabetes. With effective treatment, early chronic complications can potentially be reversed.
