What is Internal Medicine?
Internal medicine or general medicine is the medical specialty dealing with the prevention, diagnosis, and treatment of adult diseases. Physicians specializing in internal medicine are called internists. Even if you don’t have current medical needs, it’s important to have a primary care doctor.
