Do You Recognise Yourself in This?

The full symptom picture of PMOS — and why so many women were told their symptoms were something else entirely

There is a particular kind of medical gaslighting that does not announce itself.

It does not tell you that you are making things up. It just routes you through a system that treats each symptom as a separate problem — and never asks what they have in common.

Skin to a dermatologist. Cycles to a gynaecologist. Weight to a GP. Mood to another referral. Fatigue attributed to busy life. Hair thinning attributed to stress. Blood sugar just within range, so nothing to follow up.

And the woman in the middle of all of this, managing five separate concerns with five separate responses, having never been told that there is one pattern underneath all of them.

That pattern is PMOS — polyendocrine metabolic ovarian syndrome, the condition recently renamed from PCOS. And the reason it was missed in so many women for so long is not simply that the tests were inadequate. It is that no one was looking at the whole picture.

This post is about the whole picture. Read it slowly. Notice what lands.

PMOS is a multisystem condition

This is the most important thing to understand about PMOS: its features span the entire body, not just the reproductive system. That is precisely why it was missed. Clinicians trained to look at one system at a time were seeing parts of a condition they were never prompted to connect.

Symptoms can range from mild to severe. They develop gradually, which contributes to normalisation — both by the woman experiencing them and by the clinicians she sees. Not every woman has every feature. Many have four or five, presenting to different specialists over years, never assembled into a coherent picture.

Metabolic and endocrine symptoms

•          Insulin resistance — present in approximately 85% of women with PMOS, including lean women with no elevated BMI

•          Fluctuating energy, blood sugar crashes, afternoon fatigue, strong cravings — particularly for carbohydrates and sugar

•          Abdominal weight gain and persistent difficulty losing weight despite doing 'everything right'

•          Elevated androgens — testosterone, DHEAS — showing up on bloods or as physical symptoms

•          Altered cholesterol and triglyceride profiles

•          Elevated inflammatory markers — CRP, homocysteine

Insulin resistance is where most of this begins. It drives androgen excess, which drives many of the other symptoms downstream. And yet fasting insulin is not included in standard blood panels. A normal fasting glucose — which is what is routinely tested — can be completely normal even in a woman with significant underlying insulin resistance. A normal result does not mean no problem. It means the wrong thing was tested.

 

Reproductive symptoms

•          Irregular, infrequent, or absent periods

•          Cycles that occur without ovulation — meaning no egg is released, even when a period does come

•          Subfertility or unexplained infertility

•          Difficulty conceiving that was investigated but never fully explained

For many women, fertility is the first time the medical system takes the full picture seriously. That window activates something. But what happens to the woman who never tries to conceive? She is often left entirely unmanaged — her metabolic pattern present and progressing, her symptoms managed piecemeal, her underlying condition never named.

Skin and hair symptoms

•          Acne — particularly jawline, chin, and lower face

•          Excess facial and body hair (hirsutism)

•          Scalp hair thinning or androgenic alopecia

•          Acanthosis nigricans — darkened, slightly thickened skin in body folds such as the neck, armpits, and groin. This is a visible marker of insulin resistance, and it is frequently unrecognised as such

Skin and hair symptoms are often the presenting complaint — particularly in younger women. Acne goes to a dermatologist, who prescribes a topical treatment or Roaccutane. Hirsutism is addressed with an anti-androgen. The skin improves, or partially improves. Nobody asks why the androgens were elevated to begin with.

Neurological and psychological symptoms

•          Anxiety — often described as a low-level hum that does not have an obvious external cause

•          Depression

•          Brain fog, poor concentration, difficulty retrieving words

•          Disordered eating patterns — often driven by blood sugar instability rather than psychological cause alone

•          Reduced quality of life, even in women who do not meet the threshold for a formal mental health diagnosis

These symptoms are real and they are common. They are also among the most frequently dismissed. Mood changes attributed to stress. Cognitive symptoms attributed to age or hormones. The metabolic picture underneath — which is driving much of what the woman is experiencing — is rarely investigated.

Other symptoms

•          Chronic fatigue

•          Chronic pain

•          Sleep disturbances

•          Elevated risk of sleep apnoea — including in women who are not overweight

Read those lists again. Count how many of those symptoms are routinely treated as separate problems, unrelated to each other, unrelated to any unifying diagnosis. That is exactly what has been happening. For decades. To millions of women.

Why so many women were missed — and still are

The most direct cause of misdiagnosis was the name itself. Clinicians looking for cysts dismissed women who did not present with obvious ovarian follicular changes on ultrasound. Up to 20-25% of women who have the full metabolic and hormonal picture of PMOS show no relevant ultrasound findings. Under the old diagnostic framework, they did not qualify for the diagnosis. They were sent away.

 

The assumption that it only affects overweight women

This one is persistent and it is damaging. Insulin resistance in PMOS is a feature of the underlying endocrine condition — not simply a consequence of carrying extra weight. Lean women with PMOS have insulin resistance, elevated androgens, dyslipidaemia, and cardiovascular risk markers without elevated BMI. They are routinely told that their symptoms are normal, that they are too slim to have this condition, that their bloods look fine.

Their bloods look fine because the wrong things are being tested.

Fasting insulin is not part of standard testing

This is the clinical gap that I find hardest to accept, because it is entirely solvable.

Insulin resistance is the central driver in approximately 85% of PMOS cases. And yet fasting insulin is almost never included in a standard diagnostic workup. A fasting glucose test — which is what is routinely ordered — can be completely normal in a woman with substantial underlying hyperinsulinaemia. The result looks fine. The problem is active and progressing.

A shift from glucose-centric to insulin-centric testing has been called for in the research literature for years. It has not yet reached most standard care.

Symptoms were normalised

Irregular periods will sort themselves out. The fatigue is because you are busy. The acne is your diet. The hair thinning is stress. Come back if it gets worse.

I have heard versions of this from almost every woman I have worked with in this area. Not because the clinicians were careless — many of them were doing exactly what their training equipped them to do. But the training, built on a framework that missed the metabolic picture entirely, produced a pattern of normalisation that delayed diagnosis for years and sometimes decades.

Care was triggered by fertility, not health

For many women, genuine clinical attention arrived only when they wanted to become pregnant. Before that — even with years of symptoms — the system was not prompted to look for a pattern. After that, if pregnancy was achieved, the metabolic health picture was frequently set aside again.

The woman who never sought pregnancy was often never investigated at all.

What this means for you right now

If you have recognised yourself in any of this — or if you have a daughter, or a sister, or a mother whose history suddenly looks different through this lens — the most useful thing you can do is start asking better questions.

Not whether you fit a set of criteria. Whether the pattern is there.

In my next post I am going to write about what happens when you carry this metabolic pattern into perimenopause and beyond — and what a whole-body approach to addressing it actually looks like. It is the hopeful part. And it is genuinely hopeful.

Frequently Asked Questions

Can I have PMOS if I am slim and my blood tests have always come back normal?

Yes. Insulin resistance — the central driver of PMOS — is a feature of the underlying endocrine condition, not simply a consequence of excess body weight. Lean women with PMOS have insulin resistance, elevated androgens, and cardiovascular risk markers without elevated BMI. Standard blood tests frequently miss this because they measure fasting glucose rather than fasting insulin. A normal fasting glucose result does not rule out significant insulin resistance.

How is insulin resistance tested if it is not on standard panels?

The most practical clinical approach is to test fasting insulin alongside fasting glucose, then calculate HOMA-IR — a straightforward formula that gives a meaningful picture of insulin resistance status. This is not a complex or expensive test. It is simply not included in standard diagnostic workups. Requesting it specifically from your GP, or having it assessed as part of a comprehensive functional health consultation, is the most direct route.

I was told I do not have PCOS because my ultrasound was clear. Does the PMOS rename change that?

It should prompt a reassessment. Up to 25% of women with the full metabolic and hormonal picture of PMOS show no relevant changes on ovarian ultrasound. The diagnostic criteria for PMOS (previously PCOS) require two of three features — androgen excess, irregular ovulation, or excess antral follicles on ultrasound. A clear ultrasound rules out only one of those three criteria. If the other two are present, a diagnosis may still be appropriate.

My teenage daughter has some of these symptoms. Is this relevant for her?

PMOS can present from puberty onward. Irregular periods, acne, hair changes, and weight changes in adolescence can all be early indicators of the underlying metabolic pattern. Early identification and metabolic support at this stage carries significant long-term benefit — preventing My teenage daughter has some of these symptoms. Is this relevant for her?

PMOS can present from puberty onward. Irregular periods, acne, hair changes, and weight changes in adolescence can all be early indicators of the underlying metabolic pattern. Early identification and metabolic support at this stage carries significant long-term benefit — preventing the condition from compounding over decades. If you are concerned, a clinical assessment that includes the metabolic picture (not just reproductive hormones) is the right starting point.

I had a PCOS diagnosis years ago. What should I do now?

The rename does not change your diagnosis — it reframes it. If your care to date has been symptom-focused (the pill for cycles, skin treatments for acne, weight loss advice without metabolic investigation), it is worth revisiting the metabolic picture with a practitioner who works in this area. Fasting insulin, inflammatory markers, and a full lipid panel are a good starting point. A Foundational Health Assessment is designed exactly for this kind of reassessment.
