Shiree Walker - ND
Nurse Practitioner and Functional Medicine Practitioner

My name is Shiree Walker and I am a Nurse Practitioner and Functional Medicine Practitioner.  I specialise in the treatment of women's hormones and a range of other functional areas.  I have worked as a Registered Nurse in Perth, Western Australia for 20 years in a variety of specialist areas including mental health, respiratory medicine, surgical wards, dermatology, endocrinology, intensive care, palliative care, hospital in the home, wound care, stomal therapy, continence/urology/gynaecology/sexual health, emergency medicine, research and aesthetics.

I have developed a strong interest in integrative and functional medicine after having worked in the public health system for 20 years and caring for many patients with chronic diseases and conditions. I wanted to learn more about the prevention of chronic diseases and the reversal of disease through lifestyle changes and management.

My Health Story

In 2009 I was formally diagnosed with Endometriosis, although I believe I had symptoms of this disease since my early teen years. Beside surgical and medication management I was not given a lot of other information on ways to manage this disease, so I just continued on with life as such and continued in a cycle of further surgery and hormone/medication management.

In 2016 I started to develop tiredness and fatigue. The more I slept the worse I felt. It was a struggle to make it through the day. I had also put on weight which I was struggling to lose. I went to see my GP at the time who told me that I needed to just “go on a holiday”. Previous blood tests had all returned as normal. I sought out an appointment with a Functional Health Doctor. She ordered several tests (including 24hr urine collections, saliva tests) which led to a diagnosis of adrenal fatigue. I soon commenced on several supplements, herbs and compounded medications to support my adrenal glands, as well as to help manage the endometriosis. I have made major lifestyle changes and have read and researched ALOT of information about endometriosis, periods and women’s health.

Journey to Functional Medicine

In 2015 I came across an article on the use of intravenous nutrients (including vitamins and minerals) which may assist with achieving optimal health. I subsequently completed a course where I learnt about the power of nutrient therapy its potential uses in the treatment of viral infections, chronic disease states, fatigue, diabetes inflammation, toxicities and various other health issues. It was interesting to hear that Dr Myers (a Physician in Baltimore) was treating his patients with IV nutrients in the 60’s and 70’s. This started my dive into functional medicine.  In 2015 I also started a career in Aesthetics. Having a background in wound care my love of “all things skin” was reignited, especially in the area of acne management (including scar management).

After going through my own health struggles I decided to continue my functional medicine development completing functional medicine “Balancing Hormones” training. I loved the patient centered approach to health care and seeing patients heal using a functional medicine treatment model. I also went onto complete a Professional Certificate in Integrated Health & Dermatology and was able to incorporate this knowledge when treating my aesthetic clients in regards to managing their skin complaints. I felt that during these appointments there was so much more information I wanted to share with clients- whether it be that they needed further testing to formally assess some of their symptoms and underlying health conditions or that simple lifestyle changes could help improve their health overall.

This path led me to make the formal move into Functional Medicine and begin my study with the Institute of Functional Medicine and my mentorship with Jarrod Cooper – ND.  Since then I have immersed myself in functional medicine, learning from leading practitioners all over the world and continuing to develop my functional medicine expertise.
