medicine is the art and science of healing as practiced by physicians and similar professionals and encompasses all sciences related to it. it is the applied science or practice of the diagnosis, treatment, and prevention of disease. it encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness in human beings.
contemporary medicine applies health science, biomedical research, and medical technology to diagnose and treat injury and disease, typically through medication or surgery, but also through therapies as diverse as psychotherapy, external splints & traction, prostheses, biologics, ionizing radiation and others.
internal medicine is the medical specialty concerned with the diagnosis, management and nonsurgical treatment of unusual or serious diseases, either of one particular organ system or of the body as a whole. according to some sources, an emphasis on internal structures is implied. in north america, specialists in internal medicine are commonly called "internists". elsewhere, especially in commonwealth nations, such specialists are often called physicians. these terms, internist or physician (in the narrow sense, common outside north america), generally exclude practitioners of gynecology and obstetrics, pathology, psychiatry, and especially surgery and its subspecialities.
because their patients are often seriously ill or require complex investigations, internists do much of their work in hospitals. formerly, many internists were not subspecialized; such general physicians would see any complex nonsurgical problem; this style of practice has become much less common. in modern urban practice, most internists are subspecialists: that is, they generally limit their medical practice to problems of one organ system or to one particular area of medical knowledge. for example, gastroenterologists and nephrologists specialize respectively in diseases of the gut and the kidneys.
