Internal Medicine is the branch of medical science concerned with the diagnosis, management and nonsurgical treatment of unusual or serious diseases. Most of the internists (internal medicine specialists) are subspecialists: 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 related to gut and the kidneys.
