Let's Be Heard: Rewrite the National Guidelines for Endometriosis

Endometriosis affects more than 1 in 7 women, girls & those assigned female at birth in Aotearoa, yet national care guidelines haven't been updated since 2020

That means thousands are still being dismissed, misdiagnosed, or left without the support they need. Endo Warriors Aotearoa is calling on the Ministry of Health, Te Whatu Ora, and other key decision-makers to change this.

We've launched a petition and submitted a community-led review of the guidelines and we need your voice to help drive it forward.

8–10 Year Wait
People face years of pain and dismissal before getting a diagnosis, with Māori, Pasifika, disabled, and gender-diverse communities waiting even longer.

Outdated Guidelines
The national guidelines (last updated in 2020) are not enforceable, lack equity planning, and fail to protect patients.

Limited Care Options
Current care focuses on a narrow set of treatments, leaving people without the full range of support needed for pain relief, quality of life, and long-term wellbeing

Lack of Inclusivity
The guidelines overlook the needs of Māori, Pasifika, disabled, and gender-diverse people, widening health inequities.

Together, we can demand the recognition, care, and justice our community deserves. Sign today

Our Founder

Meet the heart behind Endo Warriors Aotearoa

Yessenia Sandoval -She/They

Founder & Charity Director

"La unión hace la fuerza." - Unity makes strength.

Born in Wellington to Chilean indigenous heritage, Yessenia's journey with endometriosis spans over two decades. After years of feeling unheard and isolated, she founded Endo Warriors Aotearoa in February 2020.

From her father Jorge, a political refugee from Chile, she learned the importance of advocacy and aiding others. This foundation of strength and determination drives her mission to ensure no one faces endometriosis alone.

Through personal battles with endometriosis, PCOS, infertility, and multiple surgeries, Yessenia understands intimately the struggles faced by Women, Girls & Those Assigned Female at Birth living with these conditions.

"It was on this page that I first became aware of the symptoms I was living with most of my life, I had no idea what endometriosis was until I saw the creator of this page share on her personal page about her Endometriosis Journey so I decided to check the page out, A few months later I was rushed to Hospital and was diagnosed with Mild Endometriosis, I am grateful to be part of this Amazing Support Group, This page has made me more aware of my illness and has given me the knowledge and tools to use when dealing with my GP, Gynaecologist and even trying to explain to my Family and Friends what Endometriosis is, I feel empowered and don't feel I'm on this Journey alone, I am so grateful for Endo Warriors Aotearoa"

Testimonials

"I just wanted to message and say thank you for everything you do. I struggled with endo for years and I wish I had something like this page while I was going through it all. I felt so alone and like no one was experiencing the pain that I was, so I am so glad that others have this page. please let me know if I can help in any way, I would be honoured to support such an amazing person ❤"

"Thanks to Instagram accounts like yours I would have not learnt about the ins and outs of endometriosis. Reading your guy's stuff and relating to it made me realise I might have endo. Luckily I advocated for myself and now I'm just waiting for my lab results."
