Special Interests

WOMEN'S HEALTH

Many women don’t realise that they can improve their irregular periods, painful cramps, tender breasts,
awful PMS, unusual hair growth, hair loss and more with diet and lifestyle. It is not normal to have these
areas out of sync as we have been told previously.
I am passionate about helping women improve their health by understanding how their hormones work.
Hormones are all linked. Assessing oestrogen, testosterone, cortisol, insulin and thyroid hormones
provides a detailed picture on how to fix the root cause of the problem.
Besides the mentioned above, I am enthusiastic about addressing endometriosis, polycystic ovarian
syndrome (PCOS), infertility, menopause, and reducing the risk female health cancers.
I use several tools to guide me such as genetic tests, blood tests and the DUTCH test.

functional nutrition

This is a unique approach to health care. Functional nutrition, also called integrative medicine, looks at
how cells work in your body. When you start at this cellular level, you improve health from the root. This
approach often provides patients with improved health and relief of symptoms they have not managed
yet with conventional medical treatment. I think of functional nutrition like finding out why you keep
getting cut on your hand so you can stop being cut. Compared to the traditional medicine approach that
keeps giving you plaster for your cuts.
Functional nutrition approach can be applied to all areas of health such as heart health, weight,
inflammation and more.
I have done several extra studies to become an expert in this field such as Functional Nutrigenomics and
Manuka.

gut health

A poor functioning gut is not just about the obviously conditions like constipation, diarrhoea or IBS. Your
gut is a massively integral part of your overall health. An unhealthy gut will affect how regularly you get
sick, your mental health, your weight and more.
I am passionate about helping you resolve your gut issues and by looking at holistic health and systems,
also improve other areas of your health you didn’t know were connected.
