Understanding Chronic Diseases: Types, Causes, and Impacts on Health

Chronic diseases, persistent conditions lasting 3 months or more, severely impact health. They cannot be prevented by vaccines or cured solely with medicine. Common examples include heart disease, cancer, diabetes, and arthritis. Lifestyle factors such as poor diet, smoking, and lack of exercise contribute to these illnesses. Moreover, environmental factors like pollution and stress play a significant role. Understanding these diseases and their risk factors is crucial for prevention and management to enhance overall well-being.
