Disease prevention is a process in which people, particularly those who have risk factors for a disease, are treated in an attempt to avoid getting sick. Treatment usually begins either before or shortly after the first signs and symptoms of the disease appear. Patient education, lifestyle changes, and medication are all options for treatment. Disease management is the concept of lowering health-care expenditures and enhancing quality of life for those who have chronic diseases by preventing or mitigating disease consequences through integrated treatment. Disease management is a set of coordinated health-care activities and communications for specific patient populations with conditions that can be managed with self-care. Individuals with disease management engage with other health care experts to manage their disease and avoid complications.
