What is internal medicine?

Internal medicine encompasses the care of patients 18 and older, whether they are healthy or sick. Internal medicine specialists are also called internists. They are primary care doctors recognized for their expertise in diagnosing and treating chronic illness, and working to promote health and prevent disease. Their responsibilities include health maintenance and disease screening, diagnosis and care of acute and chronic medical conditions, and management of patients with multiple complex medical problems.
