What symptoms & health problems can Functional Medicine help with?
A Functional Medicine Practitioner can help with a wide range of symptoms and health problems by addressing their root causes. I use Functional Medicine to help with…
Metabolic Health
Helping you achieve healthy and sustainable weight Loss and body composition while reversing or lowering the risk of Type 2 Diabetes, Insulin Resistance, Non-Alcoholic Fatty Liver & Metabolic Syndrome.
Cardiovascular Health
Supporting you if you are at risk of or looking to prevent the progression of heart disease, stroke, high blood pressure and the associated risk factors relating to coronary arterial disease.
Gut Health
Helping clients overcome the frustrations and limitations caused by chronic digestive symptoms associated with IBS, IBD, reflux, constipation, SIBO and more.
Energy & Fatigue
Start to feel yourself again, get back to the activities you love and overcome the burden of chronic fatigue and energy issues impacting on your physical and mental state.
Athletic Performance & Recovery
Don’t let impaired recovery and health status impact on your physical performance, hampering the consistency of your training due to niggling injuries, impaired immune function and energy levels.
Sustainable Lifestyle & Health Transformation
I want you to feel fully supported and reduce the overwhelm that can often come when embarking on a health optimisation journey.
Everyone’s journey is unique and therefore how long it takes for you to achieve your goals will vary. However, know that working with me makes achieving your goals more of a reality and a process that you can enjoy rather than fear.
Functional Medicine is about creating a therapeutic partnership that develops over time. As we learn more about you, we are better positioned to personalise the recommendations and support that you require to meet your goals. Doing this allows us to focus on the underlying causes and layering in interventions so that you can achieve your goals.
This is why my ongoing Functional Medicine Support program includes unlimited consultation time, instant messaging and email support from me as well as administration support from Fay.

Functional Medicine FAQ's
1. What is Functional Medicine?
Functional Medicine is a patient centred approach, where the patient and the practitioner work together to develop a plan of action that is individualised to your own needs and capabilities.
A Functional Medicine Practitioner appreciates the connection between all systems in the body, choices, and our environment. Rather than treating that one area or one symptom, the idea is that you understand about the person as a whole and work from there.
Functional Medicine Practitioners consider the impacts of nutrition, lifestyle, genetics, psychology, physiology, our individuality, our history, traumas, and current environments. We then use a science-based approach to facilitate investigations, treatment and support strategies to help you achieve your health and wellness goals.
Functional Medicine is about treating the person, not the disease!
2. What are the benefits of Functional Medicine over traditional medicine?
Functional medicine offers a holistic and personalised approach to healthcare that focuses on identifying and addressing the root causes of illness rather than just treating symptoms. In contrast, conventional medicine often focuses on managing symptoms with medication, which can sometimes overlook the underlying issues.
As a functional medicine practitioner, I take the time to understand your unique health history, lifestyle, and genetic factors, creating a comprehensive and tailored health plan. This approach can lead to more effective and sustainable health outcomes, as it aims to restore balance and optimise function across all body systems.
Unlike conventional medicine, which can be reactive and often involves a one-size-fits-all treatment approach, functional medicine is proactive and individualised. This can result in not only improved physical health but also emotional well-being, as you feel more in control and understood.
The emotional benefits include feeling heard, supported, and empowered to take control of your well-being, leading to a more fulfilling and healthier life.
