Subspecialist
Subspecialists in internal medicine have chosen to receive additional, more in-depth training and board certification in the diagnosis and management of diseases of a specific type (e.g., infectious diseases) or diseases affecting a single organ system (e.g., the heart). Although subspecialists often see patients for a limited basis in consultation from a general internist or another medical specialist, they too may develop long and rewarding relationships with patients who have ongoing or chronic illnesses that demand continued care.
Once general internal medicine residency training is complete, a physician may begin to practice internal medicine. Alternatively, many physicians wish to obtain further subspecialty training in a more limited area with a plan to focus their future activities on diseases of one type or organ system. Subspecialty training, called fellowship, usually adds two to three years after medical residency. Applications for fellowship are generally submitted during the second year of the internal medicine residency.
