Internal medicine is a field of practice focused on treating adults. Doctors prevent, diagnose, and treat diseases that afflict all adults, from chronically ill patients to short-term care. Once a doctor completes an internal medicine residency, they are subsequently referred to as internist. Internists typically choose to subspecialize on one illness or one part of the body. For example, a cardiologist concentrates their focus on heart-related issues, while an endocrinologist deals with hormonal issues related to glands. An internist’s specific medical training enables them to provide precise medical guidance, which is necessary for both disease prevention and routine care. Depending on a patient’s medical condition, they may be required to see separate internists, which can be costly and time-consuming. However, the specific, focused care of all internists is something that should not be ignored by patients.
Internal medicine physicians are specialists who apply scientific knowledge and clinical expertise to the diagnosis, treatment, and compassionate care of adults across the spectrum from health to complex illness.
