Internal medicine is a broad specialty that provides physicians with a strong medical foundation. Many internists choose to pursue additional subspecialty training through fellowships after completing their internal medicine residency. This path opens up career opportunities in cardiology, gastroenterology, oncology, and many other fields.
This comprehensive guide examines the typical internal medicine path to fellowship and key steps along the way.
Overview of Internal Medicine Training
Here is a high-level overview of the training roadmap
-
Medical School (4 years) Earn a medical degree (MD or DO)
-
Internal Medicine Residency (3 years): Complete a core internal medicine residency program. Gain broad medical knowledge and clinical skills.
-
Subspecialty Fellowship (1-3 years): Pursue focused training in a subspecialty like cardiology or endocrinology via a fellowship after finishing residency.
-
Board Certification: Become certified in internal medicine by passing board exams. Earn subspecialty board certification after fellowship.
This step-by-step path allows physicians to train extensively in internal medicine before specializing further through fellowships if desired.
Choosing a Fellowship
When considering fellowships, explore which subspecialties interest you most. Factors to weigh include:
-
Patient Population – What types of patients and conditions do you want to manage?

23 Internal medicine subspecialties future physicians should consider
While a general internist sees adult patients of all types and treats numerous conditions, subspecialists focus on specific types of diseases, organ systems, or patient populations. To become a board-certified subspecialist, you must complete the appropriate internal medicine fellowship following residency and pass the corresponding American Board of Internal Medicine(ABIM) certification assessment .
Note that, unless specified otherwise, each of the career descriptions below is informed by the Fellowship and Residency Electronic Interactive Database (FREIDA) Specialty Guide from the American Medical Association (AMA). Information about specific certification requirements—a valid medical license, demonstrated clinical competence, and a passing score on the appropriate exam are standards for each subspecialty—are from the ABIM as well as the American Board of Allergy and Immunology (ABAI).
Physicians who subspecialize in adolescent medicine work with patients who are transitioning from childhood to adulthood. While this may sound similar to pediatrics, adolescent medicine specialists don’t work with children until they’re around the age of 10 or 11. They address adolescents’ primary care needs and also provide care related to reproductive health, eating disorders, chronic illness, substance misuse, and sports medicine.
