Functional Medicine FAQ
What is Functional Medicine
Functional Medicine is a personalised, root-cause approach to health. Rather than focusing only on symptoms or diagnosis, it looks at how and why imbalances develop — considering factors such as nutrition, gut health, hormones, immune function, lifestyle, and environment.
It is particularly helpful for chronic, complex, or unresolved symptoms, where standard testing may appear “normal” but you don’t feel well.
The goal is not just symptom relief, but to support long-term health, resilience, and prevention through targeted, individualised care.
How is it different from Nutrition Therapy?
We are fully qualified Nutritional Therapists, and nutrition remains a core part of our work. However, our approach goes beyond standard nutrition therapy alone.
In addition to diet and lifestyle support, we incorporate functional testing, advanced clinical interpretation, and a systems-based approach to health. This allows us to investigate underlying drivers such as hormonal imbalances, gut dysfunction, immune activity, and metabolic health, rather than focusing on nutrition in isolation.
In practice, this means your plan is not just based on general dietary advice, but on a deeper understanding of your physiology and individual biochemistry, allowing for more targeted and personalised recommendations.
Do you work with other practitioners or doctors?
Yes. We regularly work alongside GPs, consultants, and other healthcare practitioners to ensure you receive well-rounded, coordinated care.
Functional testing and nutritional strategies are designed to complement medical care, not replace it. Where appropriate, we may recommend further medical investigation or liaise with your existing healthcare providers.
What can I expect from my first consultation?
Your first consultation is a comprehensive, in-depth assessment of your health — and importantly, a significant amount of preparation is done before we even meet.
Ahead of your appointment, we will have already reviewed your health questionnaire, previous test results, and any additional information you’ve provided. This allows us to begin identifying patterns and potential root causes in advance, so the consultation itself is more focused, efficient, and clinically meaningful.
What differentiates our approach is that we do not look at symptoms or systems in isolation. Instead, we take a whole-body, systems-based view, recognising that areas such as gut health, hormones, immune function, metabolism, and nervous system regulation are all interconnected. We are particularly focused on joining the dots across these systems, which is often where underlying drivers of complex or persistent symptoms are found.
During the consultation, we will explore your:
• Current symptoms and concerns
• Medical and health history
• Diet, lifestyle, stress, and sleep
We will then begin to map out a clear, personalised plan, which may include targeted testing, nutrition, supplement and lifestyle strategies.
The emphasis is on depth, clinical insight, and connecting patterns, rather than a generic or symptom-based approach.
What can I expect from subsequent consultations?
Follow-up consultations are where we review progress and refine your plan based on how your body is responding. By this stage, we are able to review changes in symptoms, lifestyle factors, and test results in detail, and determine what is improving, what is not, and what needs to be adjusted.
This is often where meaningful progress is made, as small but targeted changes can have wide-reaching effects across multiple systems.
These consultations are structured, focused, and responsive — ensuring your plan evolves in a measured and evidence-informed way as your physiology changes over time.
How many consultations do people generally have?
This varies depending on your goals and the complexity of your case.
Some people come for short-term, targeted support, while others with more complex or long-standing issues benefit from a longer-term, structured approach.
We typically recommend an initial phase of 2–4 consultations to properly assess, test (if needed), and implement a personalised plan. From there, follow-ups are tailored to your progress.
At what point could I expect to feel better?
This varies depending on the nature, duration, and complexity of your symptoms, as well as how your body responds to change.
Many people report feeling some improvement within the first consultation or shortly afterwards, particularly in areas such as clarity, reassurance, understanding of their symptoms, and initial symptom shifts once simple changes are implemented.
More sustained physiological improvements — such as energy, digestion, hormonal balance, or immune resilience — typically develop over a longer period, as underlying imbalances are addressed in a structured and progressive way.
Our focus is on identifying and treating root causes rather than suppressing symptoms, which means improvements tend to build over time and are often more stable and long-lasting.
We will always set expectations based on your individual case so you have a clear understanding of what is realistic at each stage.
