Get the care you need to overcome health challenges and restore balance in your life.
Digestive Disorders
(Eg. IBS, SIBO, Leaky Gut) Learn how Functional Medicine tackles bloating, pain, and indigestion by addressing root causes like gut microbiome imbalances, food sensitivities (eg gluten/dairy and lectins), and parasites. Restores gut health naturally—moving beyond symptom management to lasting relief.
Hormonal Imbalances
(Eg. PCOS, Thyroid Disorders, Menopause, Andropause) Hormones play a crucial role in regulating your overall health and wellbeing, often working behind the scenes. Discover how these powerful chemical messengers impact your daily life and learn about the essential hormone tests that can provide a clear picture of your current hormonal status. Don't let invisible imbalances affect your quality of life – arm yourself with knowledge and take control of your hormonal health today.
Fertility
(Eg Infertility, Miscarriage, Advance maternal age) Difficulty conceiving can be linked to hormonal imbalances, nutrient deficiencies, or chronic inflammation. Functional Medicine enhances fertility and optimises baby health by addressing root causes— addressing toxicity, balancing hormones, improving egg and sperm health with key nutrients, and reducing stress to create the ideal environment for conception and beyond.
Autoimmune Conditions
(Eg. Hashimoto’s, Rheumatoid Arthritis) Autoimmunity results from the interplay of genetic predisposition with environmental triggers like leaky gut, toxicity, and infection. Learn how to calm immune system dysfunction and over-activity, address underlying causes and achieve remission using diet, supplementation and lifestyle modification.

I’m Dr. Catherine Casey and I’ve walked this path too, and I understand your experience firsthand
I’ve felt the frustration of being told, ‘Everything looks normal,’ while still feeling far from healthy. I’ve seen the gaps in our system—as both a patient and a doctor—and how the focus on quick fixes often leaves people unheard and stuck in cycles of chronic illness. I’m here to help you break that cycle and find lasting solutions.
If the Doctor prescribes a medication, where do I obtain it?
We recommend patients use Camden Day & Night Pharmacy - particularly for compounded medications as these require prescision, skill and high standards in manufacturing. We can give your prescription directly to the chemist and they will contact you by phone to arrange purchase and delivery. They deliver Australia wide.
What is functional medicine, and how does it differ from conventional care?
Functional medicine focuses on identifying and addressing the root causes of health issues—like gut dysfunction, hormonal imbalances, or chronic inflammation—rather than masking symptoms. We use personalised protocols, lifestyle adjustments, and natural therapies to restore balance and empower long-term wellness.
What can I expect during a consultation?
Your first session includes a 60-minute deep dive into your health history, goals, and challenges. Follow-ups (30-45 minutes) track progress and adjust protocols. Virtual appointments are available worldwide.
Can I continue my current treatment plan with you?
Absolutely! Functional medicine can complement and enhance your existing care, or if needed, replace it. It is entirely up to you.
What consultation length do I need?
New patients typically select the 85 or 55 minute consultations. Subsequent consultations are typically 55 minutes unless they only require a very brief service such as a script renewal in which case the 25 minute option is often suitable.
