Understanding Functional Medicine: Separating Facts from Myths

Why This Was Updated?

Our specialists regularly review advancements in health and wellness, ensuring our articles are updated with the newest information as it becomes accessible.
Medically Reviewed by

Functional Medicine is an individualized approach to healthcare that examines the entire person, rather than focusing solely on a specific disease or system. It considers various health-affecting factors, including diet, genetics, hormonal changes, and other lifestyle components (Institute for Functional Medicine, 2023).Β 

Functional Medicine practitioners often utilize what they refer to as "optimal" lab values, which may differ from conventional reference ranges, to identify subtle trends that could influence a patient’s health.Β 

As Functional Medicine continues to evolve, it's important to address common myths and misconceptions to help patients make informed healthcare decisions in consultation with their medical providers.

What is Functional Medicine?

The term "Functional Medicine" was first coined in 1990 by Jeffrey Bland, Ph.D., who is often referred to as the "father of Functional Medicine." While the formal practice is relatively recent, its foundational concepts emphasize a holistic approach to health that resonates with ancient medical philosophies.Β 

Ancient medical philosophies dating 2,500 years ago, such as those attributed to Hippocrates, emphasized the importance of diet and lifestyle in maintaining health, aligning with many principles of Functional Medicine.

Key Principles

Functional Medicine is guided by several key principles, including:

  • Identifying and addressing the root causes of health issues rather than solely treating symptoms.
  • Restoring balance to the body and promoting optimal health.
  • Focusing on the interconnectedness of bodily systems, recognizing that changes in one area can impact others.
  • Encouraging patients to be active participants in their healthcare decisions.
  • Treating each patient as a unique individual with personalized health plans.

Functional Medicine emphasizes understanding the body's systems as interconnected networks. This holistic view allows practitioners to consider how changes in one system may influence others, rather than addressing isolated symptoms. While both traditional and Functional Medicine aim to improve patient health, Functional Medicine places a distinct emphasis on patient involvement and individualized treatment plans.

Myths About Functional Medicine

Below are some common misconceptions about Functional Medicine, along with clarifications based on current evidence and practices:

Myth 1: Functional Medicine is Not Evidence-Based

Evidence-Based Medicine (EBM) refers to medical practices that are grounded in rigorous scientific research and clinical expertise. Functional Medicine practitioners also strive to incorporate evidence-based approaches by utilizing peer-reviewed research and clinical studies to inform their practice.

Functional Medicine is supported by several peer-reviewed journals, such as the Journal of Integrative and Complementary Medicine, which publishes research on integrative health approaches. Additionally, articles about Functional Medicine can be found in many traditional medical journals, such as this study on its application in treating conditions like Long COVID.

Functional Medicine integrates complementary therapies like acupuncture, herbal medicine, yoga, with conventional medical practices to provide a comprehensive approach to patient care.

Myth 2: Functional Medicine is Just Expensive Wellness or "Quackery"

Functional Medicine practitioners are typically licensed healthcare professionals, including:

  • Acupuncturist
  • Certified Nutrition Specialist (CNS)
  • Dentist (DDM)
  • Doctor of Chiropractic (DC)
  • Doctor of Medicine (MD)
  • Doctor of Optometry (OD)
  • Doctor of Osteopathy (DO)
  • Naturopathic Doctor (ND)
  • Nurse Practitioner (NP)
  • Occupational Therapist (DOT)
  • Pharmacist (DPharm)
  • Physical Therapist (DPT)
  • Physician Assistant (PS)
  • Registered Dietician (RD)
  • Registered NurseΒ  (RN)

Admission to Functional Medicine certification programs generally requires a relevant advanced degree and active professional licensure.

Functional Medicine training and certification are available through organizations such as the Institute for Functional Medicine, School of Applied Functional Medicine, Rupa University, and others. Additionally, many prestigious medical schools, including Harvard Medical School and Johns Hopkins School of Medicine, offer courses and certifications in Functional Medicine, integrating these practices into their curricula.

In a 2024 US News article on Functional Medicine, Dr. Fraser Smith, assistant dean and associate professor of Naturopathic Medicine at the National University of Health Sciences in Illinois, stated, β€œTwo-thirds of their patients are going to be using it, so you can’t pretend that it doesn’t exist.”

Functional Medicine is supported by a growing body of scientific research and is recognized by various healthcare institutions. It integrates diet, exercise, mindful practices, and whole-system treatments, and has been applied in managing conditions such as chronic pain, autoimmune diseases, and diabetes. However, patients should consult with healthcare providers to determine the best treatment approach for their individual cases.

Myth 3: Functional Medicine is Only for the Wealthy

Functional Medicine treatments can vary in cost, with some initial consultations starting around $125. Prices may be higher in regions with a higher cost of living, but many providers strive to offer accessible options.Β 

Many lab tests utilized in Functional Medicine may be covered by health insurance, depending on the provider and specific insurance plan. Additionally, some organizations offer discounts on certain tests.Β 

While there may be initial costs associated with Functional Medicine, proactive health management may potentially reduce the need for more extensive treatments in the future. An increasing number of insurance providers are beginning to cover certain Functional Medicine tests and labs, especially those that overlap with conventional medical diagnostics. Consider it similar to regular maintenance for a vehicle, where early and consistent care can prevent more significant issues down the line.

Myth 4: Functional Medicine Blames Patients for Their Illnesses

Some may perceive Functional Medicine's emphasis on patient involvement as placing responsibility on the individual for their health challenges. However, this is a misconception.Β 

Functional Medicine aims to empower patients through education and collaborative lifestyle modifications, fostering a partnership between practitioner and patient. While encouraging personal accountability for health choices, Functional Medicine does not assign blame for illnesses. Instead, it seeks to understand and address the multifaceted factors contributing to a patient's health.Β 

Additionally, Functional Medicine considers genetic predispositions, environmental exposures, and societal influences as integral components in understanding a patient's health.

What Functional Medicine OffersΒ 

Once common misconceptions are addressed, Functional Medicine provides practitioners and patients with a comprehensive set of tools aimed at addressing ongoing health issues through a holistic and personalized approach. Its emphasis is on promoting long-term health and wellness, rather than solely addressing acute illnesses and injuries as they arise.Β 

A hallmark of Functional Medicine is the incorporation of lifestyle changes, including diet and exercise patterns, which can support a patient in maintaining overall health. By encouraging proactive health management, Functional Medicine may help reduce the need for extensive medical interventions over time.Β 

Functional Medicine’s holistic focus on mental, emotional, and physical well-being is designed to promote overall health and prevent illness, functioning as a comprehensive healthcare system alongside conventional treatments. Each patient receives treatments tailored to their unique needs. While treatments may share similarities, they are personalized based on current research and clinical evidence, ensuring relevant and individualized care.

How to Choose a Qualified Functional Medicine Practitioner

When selecting a Functional Medicine practitioner, consider the following tips to ensure credibility and suitability:

  1. Verify Credentials: Ensure the healthcare provider holds a valid license in their respective field, such as Medical Doctor (MD), Naturopathic Doctor (ND), Certified Nurse Practitioner (CNP), Physician Assistant (PA), Registered Dietitian (RD), or other recognized healthcare professions.
  2. Check Functional Medicine Certifications: Look for additional certifications that indicate specialized training in Functional Medicine, such as:
    • IFMCP - Institute for Functional Medicine Certified Practitioner
    • FMC - Functional Medicine Certified
    • AFMC - Applied Functional Medicine Certified
  3. Assess Communication Style: Engage in conversations with potential practitioners about their approach to care. A credible Functional Medicine provider should be willing to discuss how they personalize treatments, integrate evidence-based practices, and collaborate with patients in developing health plans.
  4. Seek Reviews and Testimonials: Research patient reviews and testimonials to gauge the practitioner’s reputation and effectiveness.
