Internal medicine physicians, called internists, focus on adult care. They diagnose, prevent, and treat various adult diseases – from blood, heart, and joint problems to conditions of the eyes, ears, skin, and reproductive organs, depending on which of the internal medicine subspecialties they focus on.
Internists listen to patients’ medical histories, perform physical exams, recommend lab tests, coordinate preventive screenings, make diagnoses, and prescribe medication or further action to address the issue. They also act as expert consultants for other physicians to help address adult medical problems.
Internal medicine doctors have different pathways. After their residency, many become general internists who address a spectrum of illnesses without limiting themselves to one medical problem or body system. Others choose to be internal medicine specialists, attending two to four more years of fellowship training, to focus on one body area and understand how it impacts the human system.
Let’s explore some of the internal medicine subspecialties that you have to choose from.

Beyond that, internists specialize in promoting people’s overall health and preventing illnesses.Back to All Articles
