Internal medicine doctors complete a three-year residency after medical school and can pursue board certification through the American Board of Internal Medicine. Many choose to specialize further through fellowship programs in areas like cardiology, endocrinology, or critical care medicine.
You need to complete four years of medical school after earning your bachelor's degree. Medical school gives you the basic knowledge and skills to diagnose and treat diseases in adults.
After medical school, you must complete a three-year residency in internal medicine. During this time, you work directly with patients under supervision. You learn to manage complex medical conditions like hypertension and diabetes.
The residency trains you in hospitals and outpatient clinics. You gain experience with different patient populations and medical problems.
Your internal medicine residency lasts three years. You rotate through different hospital departments and learn to care for adult patients with various conditions.
After finishing your residency, you can take the board certification exam through the American Board of Internal Medicine. Board certification shows you have met specific standards in your field. You need to pass written exams that test your medical knowledge and clinical skills.
Once certified, you can practice as a general internist. You must maintain your certification through continuing education and periodic testing.
If you want to focus on a specific area, you can complete subspecialty training through a fellowship. Fellowships typically require one to three years of additional training beyond your residency.
The American Board of Internal Medicine certifies subspecialties like cardiology, gastroenterology, endocrinology, oncology, hematology, nephrology, and pulmonary disease. If you become a cardiologist, you focus on heart and vascular conditions. Gastroenterology specialists treat digestive system problems.
Other subspecialties combine internal medicine with different fields. These include geriatric medicine, adolescent medicine, allergy and immunology, critical care medicine, sleep medicine, and sports medicine. You need board certification from multiple boards for these combined specialties.
Fellowship training involves intensive study in your chosen field. You work with experts and handle complex cases specific to your subspecialty.
As a general internist, you work in private practices, clinics, or hospitals. You manage chronic conditions and coordinate care for patients with multiple health problems.
Subspecialists often work in specialized settings. Cardiologists work in cardiac care units and perform procedures like catheterizations. Oncologists treat cancer patients in oncology centers. Critical care medicine specialists work in intensive care units with seriously ill patients.
Your work setting depends on your specialization. Some subspecialties involve more procedures, while others focus on managing long-term conditions. You might work in academic medical centers, community hospitals, or outpatient specialty clinics.
