What is functional medicine?
Functional medicine (FM) is a highly scientific systems biology - based approach that focuses on identifying and addressing the root cause of disease. It acknowledges that no illness develops overnight and often, more than one part of the body system may be stressed due to one cause, or there may be more than one course resulting in only one symptom.
It also acknowledges that you are an individual and how you respond to a certain body stressor, may be completely different to how another may respond.
Before a FM practitioner will give you a treatment strategy, they want to determine exactly what is happening on your timeline of health and illness, and how all your body systems are responding as a consequence - a bit like a matrix , or jigsaw if you like!
This is why FM works well for all ages and sexes.
Many people find that working with an IFM-trained provider helps them get to the bottom of perplexing problems that have eluded other clinicians for year
Why the Functional Medicine Approach Is So Different: A Deep Dive
1. Focus on Root Causes, Not Just Symptoms
One of the most significant differences is that functional medicine seeks to uncover why symptoms occur rather than just treating the symptoms themselves.
Conventional medicine often treats conditions by prescribing medications that block symptoms (e.g., painkillers for pain, antihistamines for allergies, insulin for diabetes).
Functional medicine looks deeper to understand why these symptoms arose in the first place — whether it’s inflammation, nutrient deficiencies, hormonal imbalances, gut health issues, chronic stress, or toxins.
This approach helps create lasting health improvements, not just temporary relief.
2. Whole-Body Systems Thinking
Functional medicine treats the body as an interconnected system: Imagine a web where every strand represents a part of your health — digestion, immune function, brain health, hormones, genetics, environment, and lifestyle habits. When one strand is pulled or weakened, others are affected.
Conventional medicine often isolates one organ or system to diagnose and treat. For example, high blood pressure might be treated solely with medication.
For example: Functional medicine looks at blood pressure as a symptom influenced by diet, stress, sleep, gut microbiome, toxin exposure, and more, aiming to rebalance the whole system.
3. Personalised Medicine Tailored to You
No two people are exactly alike, but conventional medicine tends to use a one-size-fits-all approach based on population averages.
Functional medicine practitioners spend a lot of time understanding your unique genetics, lifestyle, environment, and biochemical individuality. They often use advanced lab testing and detailed health histories.
This means your treatment plan is personalised, addressing your specific triggers, imbalances, and needs—not just what works on average for the general population.
4. Emphasis on Prevention and Wellness RatherThan Illness
Functional medicine is proactive rather than reactive.
Instead of waiting for disease to develop or progress (have you ever experienced the "watch and
wait" scenario, where you just watch your symptoms/pathology etc get increasingly worse until they
are bad enough for the physician to now medicate you?), functional medicine seeks to identify
early signs of imbalance and intervene with nutrition, lifestyle changes, and targeted therapies.
This emphasis on prevention encourages you to take an active role in your health, improving
quality of life and reducing healthcare costs over time.
5. Integrative Approach — Combining Science and Lifestyle
Functional medicine practitioners integrate the best scientific evidence with natural therapies and lifestyle interventions. Conventional medicine sometimes underutilises these lifestyle-based treatments, often relying heavily on pharmaceuticals and surgeries.
This might include:
Nutrition counselling
Stress management
Detoxification protocols
Exercise,
Sleep optimisation
Mindfulness practices.
6. Longer, More Collaborative Practitioner-Patient Relationships
Another key difference is the nature of the healthcare relationship: In conventional settings, patient visits are often short and focused on immediate issues. Functional medicine practitioners typically spend much more time listening to your story, understanding your health journey, and collaborating with you on a long-term plan. This partnership approach empowers patients to understand their health better and make sustainable changes.
7. Addressing Chronic and Complex Conditions
Functional medicine shines in managing chronic illnesses and complex, multifactorial health problems like autoimmune diseases, chronic fatigue, digestive disorders, hormonal imbalances, and mental health issues. Conventional medicine can struggle with these conditions because they often don’t have a single identifiable cause or a simple treatment wheras functional medicine’s holistic and root-cause approach helps many patients find relief when traditional methods have failed.
Examples: How Functional Medicine Differs in Practice
Irritable Bowel Syndrome (IBS)
Conventional treatment might focus on symptom management with antispasmodics or laxatives.
Functional medicine digs into gut microbiome imbalances, food sensitivities, stress, and inflammation to create a personalised treatment plan.
Type 2 Diabetes
Instead of just managing blood sugar with medication, functional medicine practitioners explore insulin resistance causes, diet, exercise habits, sleep quality, and gut health to reverse the condition.
Autoimmune Conditions
These often require lifelong immunosuppressive drugs conventionally, but functional medicine tries to identify triggers such as infections, toxins, or nutrient deficiencies to reduce autoimmune attacks.
Challenges and Criticisms
No approach is perfect. Functional medicine requires time, patient commitment, and sometimes expensive testing. It’s also still emerging in mainstream healthcare and may not be covered by insurance.
Critics argue some treatments lack robust large-scale clinical trials. However, many practitioners emphasise the importance of combining evidence-based medicine with individualised care, ongoing research, and patient feedback.
Final Thoughts
Functional medicine represents a paradigm shift in healthcare — moving from symptom suppression to root cause resolution, from fragmented care to systems-based thinking, and from generic protocols to personalised healing.
If you’ve felt frustrated by conventional medicine’s limitations, or if you’re struggling with chronic health problems that don’t respond well to traditional treatments, exploring a functional medicine approach might be a game-changer.
THE BEST OF BOTH WORLDS:
When you see a functional medicine practitioner, expect to spend a little more time than you would with a conventional medicine practitioner. You may also find that it is far more “science based” than an alternative medicine practitioner.
It is a true integration of both science and nature.

Beware Of Imitations
When trained through reputable institutions—like the Institute for Functional Medicine (IFM) in Portland, Oregon—practitioners receive rigorous, evidence-based training that integrates the latest in nutritional science, genomics, biochemistry, and clinical practice. IFM-certified practitioners follow a structured clinical framework, including detailed timelines, matrix mapping, and collaborative care plans that evolve with the patient’s progress. This isn’t a wellness trend or a vague promise of "balance"—it’s science-backed, structured, and deeply personalised care.
However, as Functional Medicine grows in popularity, so do the number of people using the term without the necessary training or standards. Unfortunately, there are many who co-opt the language of Functional Medicine but offer one-size-fits-all protocols, push unvalidated lab tests, or sell supplements without proper investigation into the why behind a person’s health issues. Genuine Functional Medicine practitioners will take the time to investigate your history, your environment, your biochemistry, and your goals before making recommendations. They are collaborative, curious, and always learning.
So, how can you tell if someone is the real thing? Ask about their training. Look for credentials from organisations like the IFM, and don’t be afraid to ask about their process. Real Functional Medicine is not about fads—it’s about science, integrity, and putting the whole person at the centre of care

What Is Naturopathy—and How Does It Differ from Functional Medicine?
Naturopathy is a holistic system of health care that combines traditional healing wisdom with modern science. It’s grounded in the belief that the body has an innate ability to heal itself when supported with the right tools—nutrition, herbal medicine, lifestyle, and environmental awareness. Naturopathic practitioners aim to treat the whole person, not just the symptoms, and always seek to understand the root cause of illness rather than suppressing it with quick fixes.
While naturopathy and Functional Medicine share many values—like personalised care, root-cause thinking, and a focus on prevention—they are not identical approaches. Naturopathy draws from a broad spectrum of natural therapies and traditional knowledge, including herbal medicine, homeopathy, iridology, and energetics. Functional Medicine, by contrast, is more explicitly grounded in systems biology and tends to lean more heavily on cutting-edge diagnostics, clinical research, and molecular science to inform its protocols.
In my practice, I blend the strengths of both models. I honour the time-tested traditions of naturopathy while integrating the rigorous, structured clinical framework of Functional Medicine (as taught by the Institute for Functional Medicine). The result is a comprehensive, evidence-informed approach that respects the body’s wisdom and the science behind its function.
As with any healing profession, it’s important to know the credentials and training of the person you're working with. True naturopathy is not about guesswork or generic “natural” advice—it’s about informed, collaborative, and individualised care that supports you on every level: physical, mental, emotional, and environmental.
Here’s A Quick Comparison:
In Conclusion:
Naturopathy is a holistic, natural form of healthcare that supports the body’s self-healing ability using time-tested tools like herbal medicine, nutrition, and lifestyle.
Functional Medicine takes a similar root-cause approach but is more heavily anchored in modern clinical science, biochemistry, and advanced diagnostic testing.
In my practice, I combine both—honouring the wisdom of traditional naturopathy while applying the structured, evidence-based methods taught by the Institute for Functional Medicine. The result? Truly individualised, whole-person care that gets to the why behind your symptoms.
IFM Certified Practitioners explain how Functional Medicine treats the whole person by addressing the underlying causes of disease. Functional Medicine is an evidence-based, systems-based approach to patient care. By focusing on the root causes of chronic illness and sustainable lifestyle change, Functional Medicine expands the diagnostic and treatment options of providers.
