The three levels of diabetes prevention:1. Primary prevention involves implementing non-pharmacological or pharmacological interventions for individuals susceptible to diabetes and those showing early signs of the condition. This approach focuses on modifying and reducing adverse environmental and behavioral factors to minimize the occurrence of diabetes.2. Secondary prevention entails screening and identifying asymptomatic diabetes patients and individuals with impaired glucose tolerance for early intervention and treatment, thereby preventing the development of complications.3. Tertiary prevention aims to prevent acute complications in existing diabetes patients through comprehensive interventions targeting all risk factors. This level of prevention works to delay and prevent the onset and progression of chronic complications, ensuring patient safety and improving their quality of life.
