About Internal Medicine
Doctors of internal medicine focus on adult medicine and have had special study and training focusing on the prevention and treatment of adult diseases. At least three of their seven or more years of medical school and postgraduate training are dedicated to learning how to prevent, diagnose, and treat diseases that affect adults. Internists are sometimes referred to as the "doctor's doctor," because they are often called upon to act as consultants to other physicians to help solve puzzling diagnostic problems.


What's an "internist"?

Simply put, internists are Doctors of Internal Medicine. Doctors for Adults.® But you may see them referred to by several terms, including "internists," "general internists" and "doctors of internal medicine." But don't mistake them with "interns," who are doctors in their first year of residency training. 

Doctors of Internal Medicine. Doctors for Adults.®

Although internists may act as primary care physicians, they are not "family physicians," "family practitioners," or "general practitioners," whose training is not solely concentrated on adults and may include surgery, obstetrics and pediatrics.

Caring for the whole patient

Internists are equipped to deal with whatever problem a patient brings -- no matter how common or rare, or how simple or complex. They are specially trained to solve puzzling diagnostic problems and can handle severe chronic illnesses and situations where several different illnesses may strike at the same time. They also bring to patients an understanding of wellness (disease prevention and the promotion of health), women's health, substance abuse, mental health, as well as effective treatment of common problems of the eyes, ears, skin, nervous system and reproductive organs.

Caring for your for life

In today's complex medical environment, internists take pride in caring for their patients for life -- in the office or clinic, during hospitalization and intensive care, and in nursing homes. When other medical specialists, such as surgeons or obstetricians, are involved, they coordinate their patient's care and manage difficult medical problems associated with that care.
