What's the Difference Between Internal Medicine and Geriatric Medicine?

4 min read

By 2030, nearly one in five Americans will be of retirement age, making specialized care for older adults more critical than ever. Understanding what's the difference between internal medicine and geriatric medicine is crucial for making informed healthcare decisions for yourself or a loved one as you age.

Quick Summary

Internal medicine focuses on diagnosing and treating illnesses in adults, often managing complex internal systems. Geriatric medicine is a subspecialty of internal medicine dedicated exclusively to the unique health, cognitive, and social needs of older adults, emphasizing holistic care.

Key Points

  • Scope of Care: Internal medicine is broad, covering general adult health, while geriatric medicine is a specialized subfield focused on the complex needs of older adults.

  • Training: Geriatricians are internists who have completed extra fellowship training in aging-related health issues, like dementia, frailty, and polypharmacy.

  • Approach: Internists often use a disease-focused approach, while geriatricians take a holistic, person-centered approach that considers the patient's entire well-being.

  • When to See a Geriatrician: It's beneficial for older adults with multiple chronic conditions, cognitive decline, complex medication lists, or frequent hospital visits.

  • Collaborative Care: Internists and geriatricians can work together, with the geriatrician offering specialized consultation for age-specific concerns.

  • Focus on Function: A primary goal of geriatric medicine is to preserve and enhance the patient's function and independence, not just to manage individual diseases.

Understanding Internal Medicine

Internal medicine is a broad medical specialty focused on the prevention, diagnosis, and treatment of diseases in adults. Internists are primary care physicians for adult patients, with expertise in a wide range of conditions affecting the body's internal systems, such as the heart, lungs, and digestive tract. They manage both simple and complex medical problems, often serving as a patient's main point of contact for routine care, health screenings, and the management of chronic conditions. Their training encompasses the entire spectrum of adult life, from young adulthood through the senior years, addressing issues that can arise at any stage.

Key areas of focus for an internist:

  • Chronic disease management (e.g., diabetes, hypertension, heart disease)
  • Health maintenance and preventative care
  • Routine physical examinations and immunizations
  • Common medical illnesses (e.g., colds, flu)
  • Diagnostic challenges for complex conditions

Exploring Geriatric Medicine

Geriatric medicine is a specialized field that focuses on the healthcare of older adults. Geriatricians are internists or family medicine doctors who have completed additional training, typically a fellowship, to gain specific expertise in the unique needs of an aging population. This specialization is vital because as people age, their health concerns often become more complex and interconnected. Geriatricians take a holistic approach, considering not just physical symptoms but also cognitive function, mental health, social support, and overall quality of life.

What makes geriatric care distinct:

  • Comprehensive Assessment: Geriatricians evaluate a patient's physical health, mental state, functional abilities, and social circumstances to create a complete picture of their well-being.
  • Multidisciplinary Approach: They often work with a team of other professionals, including social workers, physical therapists, and pharmacists, to address all aspects of a patient's health.
  • Emphasis on Function and Independence: A core goal of geriatric medicine is to help patients maintain independence and live fulfilling lives, not just manage diseases.

Distinct Differences in Training and Approach

The fundamental difference between these two fields lies in their scope and philosophy. While an internist is trained to treat adults of all ages, a geriatrician has specialized training focused on the unique medical complexities of older age. This means a geriatrician is uniquely prepared to handle issues like polypharmacy (the use of multiple medications), frailty, dementia, and falls. Their training is geared toward managing conditions that often occur simultaneously, rather than in isolation. For a deeper look into the specific training and certification processes for different medical specialties, you can refer to information from the American Board of Internal Medicine.

Philosophical difference:

An internist's approach is often disease-oriented, focused on diagnosing and treating a specific condition. A geriatrician's approach is person-centered and holistic. They consider how multiple health issues, medications, and life circumstances interact to affect the individual as a whole. They may prioritize function and comfort over aggressive disease-specific treatment, depending on the patient's goals.

Comparison Table: Internal vs. Geriatric Medicine

Feature Internal Medicine Geriatric Medicine
Patient Age All adults (ages 18+) Specifically older adults (typically 65+)
Scope Broad range of adult diseases Complex health concerns of aging
Approach Often disease-focused Holistic, person-centered
Training General internal medicine residency Residency + 1-2 year fellowship
Focus Prevention, diagnosis, treatment Function, quality of life, independence
Common Issues Diabetes, hypertension, heart disease Polypharmacy, dementia, falls, frailty

When is a Geriatrician the Right Choice?

Deciding to transition from an internist to a geriatrician is a personal choice, but certain signs may indicate that specialized geriatric care is more appropriate. These include managing multiple chronic conditions, experiencing noticeable cognitive decline, dealing with complex medication regimens, or a history of frequent hospitalizations or falls. For many older adults, the comprehensive and collaborative care model offered by a geriatrician can provide a higher quality of life. An internist can remain the primary doctor, with the geriatrician acting as a consultant to provide specialized recommendations.

The Collaborative Relationship

It's important to understand that internists and geriatricians can and often do work together. An internist may refer a patient to a geriatrician for a specialized consultation on an age-related issue, such as memory loss or managing multiple interacting medications. The geriatrician can then provide guidance to the internist, ensuring the patient benefits from both general adult care and specialized geriatric expertise. This collaborative model is a powerful way to manage the complex health needs that can arise during the aging process, ensuring a more coordinated and thoughtful approach to care.

Conclusion: Making the Right Choice for Senior Health

While internists provide excellent care for adults of all ages, geriatricians offer a deeper, more specialized level of care for older adults with complex, age-related needs. The decision often comes down to the individual's health status and personal preferences. An older adult who is in good health may continue to thrive under the care of a trusted internist. However, for those with multiple chronic conditions or concerns related to memory, mobility, or medication management, the holistic, team-based approach of a geriatrician can be invaluable. By understanding what's the difference between internal medicine and geriatric medicine, patients and families can make the most informed decision to support health and well-being in the golden years.

Frequently Asked Questions

There's no set age to switch. The best time is when health needs become complex, such as managing multiple chronic illnesses, experiencing cognitive issues, or dealing with frailty and mobility concerns.

Yes, internists are highly skilled in treating adults of all ages and can effectively manage many health issues in older adults. However, for highly complex or specific age-related conditions, a geriatrician offers specialized expertise.

This depends on your health insurance plan. Some plans require a referral from a primary care physician (like an internist) to see a specialist, including a geriatrician. It's best to check with your provider first.

Polypharmacy refers to the use of multiple medications by a patient. Geriatricians specialize in it because older adults often take many prescriptions, and managing the interactions and side effects is a crucial and complex part of geriatric care.

After completing medical school, a doctor completes a residency in either internal medicine or family medicine. Following this, they complete a 1- to 2-year fellowship specifically in geriatric medicine.

Yes, many geriatricians do act as primary care providers for their older patients. This allows them to oversee all aspects of the patient's health with a specialized focus on aging.

Discussing the options with your current internist is a great starting point. They can help assess whether your health needs warrant specialized geriatric care. A collaborative approach where both doctors are involved is also possible.
