When searching for a new primary care provider, you might come across the term “internist” or see doctors listed under internal medicine. So, what is an internal medicine doctor, and how do they differ from other types of physicians? Let’s break it down.
The Basic Definition
An internal medicine doctor, often called an internist, is a physician who specializes in the diagnosis, treatment, and prevention of diseases in adults. Unlike pediatricians, who focus exclusively on children, internists are trained to care for adult patients across a broad range of health concerns, from common illnesses to complex, chronic conditions.
Internal medicine is sometimes confused with “internship,” but the term actually refers to the internal organs and systems of the body, since internists are trained to understand how different body systems interact and affect overall health.
Education and Training
Becoming an internal medicine doctor requires extensive training. After completing medical school, physicians go through a three-year residency specifically in internal medicine, where they gain hands-on experience treating a wide variety of adult health conditions in both hospital and outpatient settings. Many internists also pursue additional fellowship training to subspecialize in areas like cardiology, endocrinology, gastroenterology, or infectious disease.
What Conditions Do Internists Treat?
Internal medicine doctors are trained to manage a wide range of health issues, including:
- Chronic conditions like diabetes, high blood pressure, and high cholesterol
- Respiratory issues such as asthma and chronic obstructive pulmonary disease (COPD)
- Heart disease and other cardiovascular concerns
- Infections and general illnesses
- Preventive care, including vaccinations and routine screenings
- Coordinating care for patients with multiple chronic conditions or complex medical histories
Because of their broad training, internists are often well-suited to manage patients who have several health issues at once, helping coordinate care between different specialists when needed.
Internal Medicine vs. Family Medicine
A common point of confusion is the difference between internal medicine and family medicine doctors. While both can serve as primary care providers, there are some key distinctions:
Internal medicine doctors focus exclusively on adults, typically starting around age 18, and often have deeper training in managing complex or multiple chronic conditions in adult patients.
Family medicine doctors are trained to treat patients of all ages, from infants to the elderly, and often focus more on preventive care and overall family health, including pediatric and sometimes even obstetric care depending on their practice.
Neither type of doctor is inherently “better” than the other; the right choice often depends on your personal needs, age, and whether you want a doctor who also treats other family members.
Internal Medicine vs. Specialists
It’s also worth noting that many specialists you might see, such as cardiologists, gastroenterologists, or rheumatologists, actually started their training in internal medicine before completing additional fellowship training in their specific subspecialty. This is why you’ll often see “internal medicine” listed as part of a specialist’s credentials, even if their day-to-day practice focuses on a narrower area.
When Should You See an Internist?
Many adults choose an internal medicine doctor as their primary care provider because of their strong training in managing chronic illness and coordinating complex care. This can be especially helpful for:
- Adults with multiple chronic health conditions
- Older adults who may need more comprehensive management of various health issues
- Patients looking for a doctor with strong experience in adult-specific health concerns
Final Thoughts
An internal medicine doctor is a physician trained specifically to diagnose and manage health conditions in adults, often with a strong focus on chronic disease management and coordinated care. Whether you’re managing a single health concern or several at once, an internist can serve as a knowledgeable, well-rounded primary care option.
