A physician, medical practitioner, medical doctor, or simply doctor is a health professional who practices medicine, which is concerned with promoting, maintaining or restoring health through the study, diagnosis, prognosis and treatment of disease, injury, and other physical and mental impairments. Physicians may focus their practice on certain disease categories, types of patients, and methods of treatment—known as specialities—or they may assume responsibility for the provision of continuing and comprehensive medical care to individuals, families, and communities—known as general practice. Medical practice properly requires both a detailed knowledge of the academic disciplines, such as anatomy and physiology, underlying diseases, and their treatment, which is the science of medicine, and a decent competence in its applied practice, which is the art or craft of the profession.
Osteopathic medicine is a branch of the medical profession in the United States that promotes the practice of science-based medicine, often referred to in this context as allopathic medicine, with a set of philosophy and principles set by its earlier form, osteopathy. Osteopathic physicians (DOs) are graduates of American osteopathic medical colleges and are licensed to practice the full scope of medicine and surgery in all 50 U.S. states. The field is distinct from osteopathic practices offered in nations outside of the U.S.—in which practitioners are generally considered neither parts of core medical staff nor of medicine itself; rather, they are considered alternative medicine practitioners. The other major branch of medicine in the United States is referred to by practitioners of osteopathic medicine as allopathic medicine.
Internal medicine, also known as general internal medicine in Commonwealth nations, is a medical specialty for medical doctors focused on the prevention, diagnosis, and treatment of internal diseases in adults. Medical practitioners of internal medicine are referred to as internists, or physicians in Commonwealth nations. Internists possess specialized skills in managing patients with undifferentiated or multi-system disease processes. They provide care to both hospitalized (inpatient) and ambulatory (outpatient) patients and often contribute significantly to teaching and research. Internists are qualified physicians who have undergone postgraduate training in internal medicine, and should not be confused with "interns", a term commonly used for a medical doctor who has obtained a medical degree but does not yet have a license to practice medicine unsupervised.
