If you’ve heard for years that your labs are “borderline” or that your symptoms are “hormones,” pause for a moment. Your fatigue, breakouts, irregular cycles, and stubborn weight shouldn’t just be managed. PCOS has a new name: PMOS. In 2026, the global medical community renamed Poly-cystic Ovary Syndrome. It is now called PMOS, or Poly-endocrine Metabolic Ovarian Syndrome. The change appeared in The Lancet. The change came through a global agreement: 56 professional and patient groups worldwide support it.
For those who see this condition as affecting the whole body, not just the ovaries, this isn’t new. It’s validation. And it’s the same shared language conventional medicine and root-cause practitioners have needed for a long time.
Let’s look at what changed, what stayed the same, and what this means for you. If you’re one of the millions of women with this condition, even if you’ve never heard the word “cyst” in your diagnosis, this is important.
This is not self-improvement content. This is information your body has been trying to hand you for years. Let’s finally read it properly.
PMOS by the numbers
Before we go further, some context for how common this is. I know it can feel extremely isolating and lonely sometimes. But you’re not rare, and you’re not imagining it.
One in eight women of reproductive age has this condition. Current guidelines put this at about 10 to 13%, and nearly 12% worldwide, based on the latest meta-analysis. That’s over 20 million women in the US alone. It’s the most common endocrine disorder in women of reproductive age. Despite its prevalence, it’s often missed in women’s health diagnoses for years.
If this is you, or someone you love, you are not the exception. You are the pattern.
Why the rename actually matters
Here’s what changed with the shift from PCOS to PMOS:
The name now reflects the biology. PMOS means Poly-endocrine Metabolic Ovarian Syndrome. This name reflects the true nature of the condition. It involves a metabolic and multi-endocrine pattern, focusing on insulin resistance and androgen sensitivity. Not a syndrome confined to the ovaries. Never was.
Here’s what didn’t change: the diagnostic criteria, the underlying condition, its risks, or its treatments. If you were diagnosed with PCOS, you now have PMOS. Nothing about your body shifted overnight. What shifted is the story medicine tells about it.
And that story matters more than it might seem. For years, women were handed a diagnosis that pointed to one organ — the ovaries — while the rest of the picture (blood sugar, gut health, stress physiology, environmental exposures) sat outside the frame. You were told to manage your cycle, sometimes with little acknowledgement of everything upstream that was actually driving it. The new name puts the whole pattern back in view. It was never just about the ovaries. It was always about the whole person.
That’s not a new idea to me, or to my clients. It’s the foundation of how I’ve practised for years. But I understand why, for so many of you, having medicine finally say it out loud might feel like the first time someone believed you.
5 roots to treat PMOS
Here’s where the real shift happens — not in the name, but in how we understand the roots beneath it. Current root-cause research identifies five interconnected roots that converge to create the metabolic and hormonal picture we now call PMOS. I think of these less as five separate problems and more as five branches of the same tree, all rising from the same soil.
Root one: metabolism. Insulin resistance sits at the centre of PMOS for the majority of women who live with it — not because you did something wrong, but because blood sugar dysregulation is often the earliest, quietest root. It shows up as fatigue after meals, sugar cravings, difficulty losing weight even with real effort, and irregular cycles. Of everything we can address, restoring insulin sensitivity through food, movement, and blood-sugar-steady meals has the strongest evidence behind it of any intervention in this entire condition — stronger than any single supplement or medication. This is not about restriction. It’s about steadiness.
Root two: the gut. Your gut does more than digest food. It contains the estrobolome. This is the group of gut bacteria that helps your body process and remove extra hormones, like oestrogen. When gut permeability and dysbiosis are present, that clearance process struggles, and inflammation from the gut feeds directly back into insulin resistance. Your gut and your hormones are not two separate stories. They are one conversation, happening in the same body.
Root three: the mitochondria. These are the energy centres of your cells. They are closely linked to your ovaries’ function and egg quality, especially for those dealing with fertility. Persistent fatigue, poor recovery from exercise, and that particular kind of exhaustion that sleep doesn’t seem to touch are often signs that this root needs attention. Movement — especially the kind that challenges your muscles, not just your endurance — is one of the most powerful tools we have here.
Root four: the HPA axis. This is your stress physiology — the conversation between your brain and your adrenal glands. And here’s something worth sitting with: roughly half of women with PMOS have elevated adrenal androgens, driven not by the ovaries at all, but by your pituitary’s response to stress. Cortisol elevation raises androgen production and disrupts ovulation. This is where I want to gently interrupt a story many of you have been told — that this is “just hormones” and has nothing to do with your nervous system, your sleep, your capacity to rest. It has everything to do with it. Your nervous system is not separate from your endocrine system. It is speaking the same language, in the same body, all the time.
Root five: body burden. This root examines your exposure to endocrine-disrupting chemicals. These come from plastics, personal care products, and your environment. It also looks at how well your body can eliminate them. The research here is still emerging and largely associative rather than proven by controlled trials, but the mechanism is plausible: these compounds can disrupt ovarian hormone production and worsen insulin resistance. Reducing exposure where you reasonably can is low-risk, even while the science continues to develop.
Five roots. One soil. They converge on inflammation, metabolic shifts, and hormonal imbalance — the exact signature of PMOS, and honestly, of most modern chronic patterns women live with. Same iceberg. Different tips showing above the water.
One conversation, not five protocols
I want to be honest about something the current guidelines get right: no single diet, supplement, or protocol solves this alone. This issue never had just one root cause. That’s precisely why women end up cycling through functional medicine coach after supplement stack after elimination diet, feeling more depleted each time, without ever feeling met.
This is the piece I’ve built my entire practice around. Your body, your patterns, and your nervous system are not separate departments to be treated by separate specialists with separate protocols. They are one conversation. When I work with clients, we don’t just chase symptoms one by one. Instead, we look at how your specific pattern appears across all five areas. Your gut inflammation connects to your insulin resistance, which links to your stress levels, and all of that affects your ovaries. Ancient diagnostic intelligence paired with modern psychological and metabolic precision, held together rather than pulled apart.
This is also where I’ll say something that might sound counter-cultural in a wellness industry built on restriction: healing this pattern is not about doing more, trying harder, or being more disciplined with your body. The guidelines themselves warn against unduly restrictive approaches, and for good reason — disordered eating is up to four times more common in women with this condition. If your plan for healing feels like punishment, it’s not the right plan. Vitality was never something you had to earn through suffering. It’s something your body already knows how to return to, once the roots are actually addressed instead of managed around.
What this means for you
If you have PCOS or PMOS and feel worn out from trying everything—the apps, supplements, diets, and specialists—it’s important to remember that your exhaustion is not your fault. It’s what happens when a whole-person condition gets treated one root at a time, by different people, none of whom are talking to each other.
This is the work I do with the women inside the m.a.n.t.r.a method, my 90-day container where we work with the body, the mind, and the soul simultaneously rather than in sequence — because your metabolism, your nervous system, and your sense of self were never actually separate to begin with. And it’s the conversation happening every week inside The Call, where my members are learning to read their own patterns instead of outsourcing that knowledge indefinitely to the next protocol.
If you need an approach that’s customised for you, I get it. In that case, try my Wellness Package. You’ll have a real consultation with a full 50-minute session. Then, we’ll have two 25-minute follow-ups. This way, we can explore your roots together instead of just guessing.
Whatever name your chart carries — PCOS or PMOS — your body’s been sending a message this whole time. It’s in a language most of the wellness industry never learned to read. But you haven’t lost your vitality. You’ve been living at a distance from it. Let’s close that distance, root by root.
