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.
Naturopathy, or naturopathic medicine, is a form of alternative medicine. A wide array of practices branded as "natural", "non-invasive", or promoting "self-healing" are employed by its practitioners, who are known as naturopaths. Difficult to generalize, these treatments range from the pseudoscientific and thoroughly discredited, like homeopathy, to the widely accepted, like certain forms of psychotherapy. The ideology and methods of naturopathy are based on vitalism and folk medicine rather than evidence-based medicine, although practitioners may use techniques supported by evidence. The ethics of naturopathy have been called into question by medical professionals and its practice has been characterized as quackery.

Doctor of Medicine is a medical degree, the meaning of which varies between different jurisdictions. In the United States, and some other countries, the M.D. denotes a professional degree. This generally arose because many in 18th-century medical professions trained in Scotland, which used the M.D. degree nomenclature. In England, however, Bachelor of Medicine, Bachelor of Surgery (M.B.B.S.) was used: in the 19th century, it became the standard in Scotland too. Thus, in the United Kingdom, Ireland and other countries, the M.D. is a research doctorate, honorary doctorate or applied clinical degree restricted to those who already hold a professional degree (Bachelor's/Master's/Doctoral) in medicine. In those countries, the equivalent professional degree to the North American, and some others' usage of M.D. is still typically titled Bachelor of Medicine, Bachelor of Surgery.
A Physician Assistant or Physician Associate (PA) is a type of healthcare professional. While these job titles are used internationally, there is significant variation in training and scope of practice from country to country, and sometimes between smaller jurisdictions such as states or provinces.

Family medicine is a medical specialty within primary care that provides continuing and comprehensive health care for the individual and family across all ages, genders, diseases, and parts of the body. The specialist, who is usually a primary care physician, is named a family physician. It is often referred to as general practice and a practitioner as a general practitioner. Historically, their role was once performed by any doctor with qualifications from a medical school and who works in the community. However, since the 1950s, family medicine / general practice has become a specialty in its own right, with specific training requirements tailored to each country. The names of the specialty emphasize its holistic nature and/or its roots in the family. It is based on knowledge of the patient in the context of the family and the community, focusing on disease prevention and health promotion. According to the World Organization of Family Doctors (WONCA), the aim of family medicine is "promoting personal, comprehensive and continuing care for the individual in the context of the family and the community". The issues of values underlying this practice are usually known as primary care ethics.

Italy's healthcare system is consistently ranked among the best in the world.

Healthcare in the United States is largely provided by private sector healthcare facilities, and paid for by a combination of public programs, private insurance, and out-of-pocket payments. The U.S. is the only developed country without a system of universal healthcare, and a significant proportion of its population lacks health insurance. The United States spends more on healthcare than any other country, both in absolute terms and as a percentage of GDP; however, this expenditure does not necessarily translate into better overall health outcomes compared to other developed nations. Coverage varies widely across the population, with certain groups, such as the elderly and low-income individuals, receiving more comprehensive care through government programs such as Medicaid and Medicare.
