Internal medicine is a branch of medicine pertaining to the prevention, diagnosis, treatment, and management of diseases affecting adults over the age of 18. Doctors who practice internal medicine are known as “internists” and often serve as a patient’s primary care provider. Internists may work together with other physicians to ensure patients are getting comprehensive care that transcends a specific symptom or health condition.

Internal medicine physicians spend a minimum of four years of their medical school and then three years of post-graduate training, learning about the diagnosis and treatment of diseases that affect adults.

The fact that our organs and systems are not independent, but interconnected in a very complex web and that’s why there’s a specialty of a medicine called internal medicine. Primary care physicians have a comprehensive understanding of the entire body and the systems within it and they are a specialist in diagnostics, long-term care, preventative medicine and more.
