Brief Description
Internal medicine is the medical specialty concerned with the diagnosis, management and nonsurgical[1] treatment of unusual or serious diseases. According to some sources, an emphasis on internal structures is implied.[2] In North America, specialists in internal medicine are commonly called, "internists". Elsewhere, especially in Commonwealth nations, such specialists are often called physicians. 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 and would see any complex nonsurgical problem; this style of practice has become much less common.
