Medical doctor
Health professional who practices medicine to promote and restore health.
A medical doctor (called a physician in the US and Canada, or a medical practitioner in the UK) is a health professional whose work is medicine. The goal of medicine is to support, maintain, or bring back health by studying, diagnosing, predicting, and treating disease, injury, and other physical or mental conditions. Some doctors choose a specialty, focusing on particular diseases, patient groups, or treatment methods. Others become general practitioners, offering ongoing, all-around medical care to individuals and families. Doing this job well requires a deep grasp of medical sciences—like anatomy, physiology, and the nature and treatment of illnesses—plus strong skill in putting that knowledge into practice, which is often called the art or craft of medicine.
The role of a doctor and the meaning of the word itself differ around the world. Degrees and qualifications vary a lot, but some things are common, such as medical ethics, which require doctors to show consideration, compassion, and goodwill toward their patients.
**Terminology**
The word "doctor" is commonly used for medical practitioners everywhere, but it can also refer to people with non-medical doctoral degrees. In North America, "physician" means any medical practitioner in a broad sense. In the UK and countries influenced by British English, however, "physician" specifically means a specialist in internal medicine.
**British and Commonwealth**
The British meaning of "physician" is the original one, and it contrasts with "surgeon," who is a specialist in surgery. This original sense of "physician" implies expertise in treating with drugs rather than with the manual procedures a surgeon uses. The English word "physician" is at least 900 years old; physicians and surgeons were once separate professions and traditional rivals. The Shorter Oxford English Dictionary (third edition) includes a Middle English quote from as early as 1400 that makes this contrast: "O Lord, whi is it so greet difference betwixe a cirugian and a physician." In 1518, Henry VIII granted a charter to the London Royal College of Physicians. It was not until 1540 that he gave the Company of Barber-Surgeons (the forerunner of the Royal College of Surgeons) its own charter. That same year, the English monarch created the Regius Professorship of Physic at the University of Cambridge.

Lore & Background
The term doctor commonly refers to medical practitioners across the world, but may also be applied to holders of non-medical doctoral degrees. In North America, physician is used to refer to medical practitioners in a general sense, while in the United Kingdom and countries influenced by British English, this word refers specifically to specialists in internal medicine. The British meaning of physician is the original one, used in opposition to surgeon, which refers to a specialist in surgery. This meaning conveys a sense of expertise in treatment with drugs, rather than manual procedures. The English word physician is at least nine hundred years old; physicians and surgeons were once members of separate professions and traditionally were rivals. Henry VIII granted a charter to the London Royal College of Physicians in 1518, and later granted the Company of Barber-Surgeons its separate charter in 1540.
Reader's Guide
Medical doctors hold a significant role in society, as they are responsible for the study, diagnosis, prognosis, and treatment of disease, injury, and other physical and mental conditions. Their practice requires both thorough knowledge of medical sciences—such as anatomy, physiology, diseases, and their treatment—and strong competence in applying this knowledge, which forms the art or craft of the profession. The role and meaning of the word vary around the world, with degrees and qualifications differing widely, though common elements include medical ethics requiring consideration, compassion, and benevolence for patients. In Western culture, medicine has become increasingly based on scientific reductionism and materialism, termed biomedicine, and doctors are considered members of a learned profession with high social status, often combined with expectations of high and stable income and job security. However, they often work long and inflexible hours, with shifts at unsociable times. Many countries face the problem of too few doctors, and increasing medical school enrollment and residency positions can help reduce physician overtimes, burnout, and improve consultation lengths.
