Chronic diseases such as diabetes, heart disease, stroke, and cancer are significant contributors to global morbidity and mortality. The transition from infectious to non-communicable diseases began in the early 1900s due to improved public health measures and has persisted. As life expectancy increases, the prevalence and cost of chronic diseases are rising, with an estimated $47 trillion expected to be spent globally by 2030. Lifestyle factors and community conditions play crucial roles in the development and management of these diseases, which are often preventable through healthy behaviors like physical activity, proper nutrition, tobacco cessation, and reduced alcohol consumption. However, investments in prevention are minimal compared to treatment. The aging population and demographic shifts further exacerbate the burden of chronic diseases. COVID-19 has also impacted chronic disease management, particularly in vulnerable populations, leading to a "health debt" and increased disparities. Addressing social determinants of health and leveraging technology for self-monitoring and behavior change are essential for reducing the burden of chronic diseases. The future requires continued innovation and a focus on prevention to manage the growing economic and health impacts of chronic diseases.Chronic diseases such as diabetes, heart disease, stroke, and cancer are significant contributors to global morbidity and mortality.
