From Wikipedia, the free encyclopedia

A medical specialist is someone who specializes in a particular field of medicine. Depending on the jurisdiction, they may be known as physicians or doctors.

Medical specialists go through additional training, above and beyond medical school and internship in order to become very knowledgeable about a specific part of the human body or a specific type of disease. They have at least two to three years of extra training, above and beyond the basic medical school curriculum, in their specific field, and they will continually research progress in their field. In the medical profession they often function as consultants, either for private practice or employed by a hospital. Typically, a general practitioner or other primary care provider will see the patient first, and if presented with a patient who needs more specialized treatment or advanced diagnosis the specialist is called in to examine the patient. The philosophy behind this approach is that the average patient will not need a specialist, so specialists do not usually see them first, but wait until specifically asked. This system has the benefit of not requiring general internists to have incredibly specific knowledge of all medical matters, an impossible feat, but allows them to delegate responsibility to those with more specific knowledge when the situation calls for it.

In the U.S. Army, the term "medical specialist" refers to occupational therapists, physical therapists, dietitians and physician assistants, also known as allied health professionals.
