The Doctor, an 1891 portrait by Luke Fildes A medical doctor, also known as a physician (American and Canadian English) or medical practitioner (British English), is a health professional who practices medicine. Medicine aims to promote, maintain or restore health through the study, diagnosis, prognosis and treatment of disease, injury, and other physical and mental conditions.
Doctors may focus on certain disease categories, types of patients, and methods of treatment, known as specialities. Others work in general practice, providing continuing and comprehensive medical care to individuals, families. Medical practice requires both thorough knowledge of the medical sciences—such as anatomy, physiology, diseases, and their treatment—and strong competence in applying this knowledge in practice, which forms the art or craft of the profession.
