Doctors of internal medicine, or internists, diagnose and treat diseases in adults. Sometimes known as a general practitioner or the “doctor’s doctor,” internists often work with surgeons, obstetricians, and other physicians to help solve complicated primary care problems in diagnosis and treatment. They also coordinate patient care where it is needed, including in the office, clinic, hospital, intensive care, or nursing home.
