Specialists in internal medicine are commonly called internists. Because their patients are often seriously ill or require complex investigations, internists do much of their work in hospitals. In modern 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.
