Welcome! I’m Rachel Hill, the multi-award winning and leading UK thyroid patient advocate, writer, bestselling author, public speaker and content creator behind The Invisible Hypothyroidism. It all started here with this website and expanded in to so much more!
I started The Invisible Hypothyroidism as a means for me to record my personal journey of living with hypothyroidism and Hashimoto’s.
I represent and help other thyroid patients by advocating for better thyroid disease diagnosis, treatment and awareness.
With over thousands of website views every month and hundreds of thousands of fellow thyroid patients following me across social media and my Substack email newsletters, I share a key message:

My Philosophy
I believe in each person with thyroid disease getting the right treatment for them, as there is no ‘one size fits all’ approach to hypothyroidism and Hashimoto’s. This is why I advocate with the aim of encouraging each thyroid patient to advocate for their health.
In my experience, living well and thriving with hypothyroidism and Hashimoto’s has been like piecing together a jigsaw puzzle. There have been many pieces and each thyroid patient can have a unique combination of pieces.
Therefore, my work – articles, books, email newsletters, public speaking, podcast and radio appearances – all bring together the various jigsaw puzzle pieces for other thyroid patients.



I am well-recognised as a valued and influential contributor to the thyroid community and have maintained a significant and engaged online presence since 2015. My audience trust me to share authentic, real insights to living with thyroid disease.
