Part of F.F. Thompson Hospital
Internists are experts in adult medicine and care for the whole patient. They solve problems with chronic and multiple illnesses no matter how simple or complex. Of all primary care physicians, the “doctors of internal medicine” (also called “internists”) are unique in their focus on adult medicine. They 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. They are specially trained to solve complicated diagnostic problems. They handle severe chronic illnesses and situations where several different illnesses may strike at the same time.
When other medical specialists, such as surgeons or obstetricians, are involved, they coordinate their care for the patients and manage difficult medical problems associated with that care.
