Progesterone, PCOS, Endometriosis and Miscarriage: Naturopath Francesca Lyon on the Hormones Changing Everything

What if the key to your mental health, fertility, and longevity was sitting quietly in one hormone most women have never been taught to protect?

In this episode, Jess sits down with Francesca Lyon, degree-qualified Naturopath and Medical Herbalist from Auckland, now based in Amsterdam, and Director of Nutrition at Future Woman, a UK-based at-home hormone testing company. Francesca has spent over 13 years specialising in women's health, hormones, fertility, PCOS and perimenopause, and this conversation is one of the most wide-ranging and genuinely eye-opening we've had on The Cyclist.

It starts with progesterone, the hormone Francesca is perhaps most passionate about, and why protecting ovulation is the single most impactful thing a woman can do for her mental health, sleep, pain levels, brain health and longevity.

She explains what happens when progesterone breaks down in the body, how it communicates with GABA, our calming neurotransmitter, and why so many women in their 30s experiencing anxiety, rage, sleep disruption and low mood are being handed anxiety medication when what they actually need is more progesterone.

Francesca shares her own story of burnout, cystic acne, a miscarriage, and a brain AVM, an arteriovenous malformation, that was diagnosed after she developed daily debilitating migraines two weeks postpartum. She had suspected the AVM for years before her diagnosis, having studied them in her psychology degree and had a gut feeling she had one, only to be told not to be silly. The moment she was finally diagnosed, her first thought was: I told you.

They go deep into miscarriage, what Francesca believes about why they happen, why she would never wait for three before investigating, and what she thinks about the deeply underfunded and underinvestigated space of pregnancy loss. She talks honestly about the grief of a lost pregnancy, the anxiety of trying again, and the client she worked with who had eight miscarriages in a year before a progesterone deficiency was finally identified and addressed.

The conversation moves through PCOS, which Francesca believes is reversible in every case when the root drivers are properly investigated, and endometriosis, which she approaches as an autoimmune and inflammatory condition, often triggered by a microbial infection. She shares her views on the gluten and dairy question for endo, the link between environmental toxins and PCOS, and why unexplained infertility is really just uninvestigated infertility.

There's also a genuinely practical section on sleep, two of Francesca's top sleep hygiene tips for hormone health, and an honest conversation about the food noise and control that can come with managing a condition like endometriosis, and when the stress of avoiding a food is worse than just eating it.

Francesca is also co-founder of Future Woman, an at-home hormone testing service using the Dutch test, with expert interpretation and a personalised protocol included, making comprehensive hormone testing accessible without the cost of multiple practitioner appointments.
