PCOS is now being called PMOS — what this means for your health

Dr Pip Nelson Gynaecologist, Belle Women's Health 1 June 2026

You may have recently seen new terminology emerging around a very common women's health condition: PCOS is now being referred to as PMOS. At Belle Women's Health, we know that clear, accurate information matters. So here's a simple explanation of what's changing, why it's happening, and what it means for you.

First — what hasn't changed

If you've previously been diagnosed with polycystic ovary syndrome (PCOS):

  • Your diagnosis still stands
  • Your symptoms are the same
  • Your treatment approach doesn't suddenly change

What's evolving is how the medical community understands and describes the condition.

So what is PMOS?

PMOS stands for Polyendocrine Metabolic Ovarian Syndrome.

It is the new name proposed by an international group of experts to better reflect what this condition actually is: a complex, whole-body hormonal and metabolic condition, not just an issue with the ovaries.

P
Polyendocrine
Multiple hormone systems are involved
M
Metabolic
Strong links to insulin resistance and long-term health
O
Ovarian
Ovulation and reproductive health are still important

This helps clinicians — and patients — understand the condition more holistically.

Why was the name PCOS changed?

1. "Polycystic ovary" is misleading

Despite the name, many women with PCOS:

  • Do not have ovarian cysts, and
  • The "cysts" seen on ultrasound are often small follicles — not true pathological cysts

This has caused confusion for years, particularly for patients told they "don't have cysts, so it can't be PCOS."

2. It's not just an ovarian condition

We understand the condition involves:

  • Hormonal imbalance (especially androgen excess)
  • Insulin resistance
  • Impacting your skin, fertility, mood, and long-term cardiovascular risk

In other words, it's not just about periods or ovaries — it affects multiple systems in the body.

3. The old name contributed to delayed diagnosis

Research suggests that:

  • Up to 70% of people with the condition may remain undiagnosed1
  • The narrow focus of the name contributed to missed or delayed diagnosis and fragmented care

By focusing on "cysts," evidence suggests the majority of cases are undiagnosed.


Will the name change affect your care?

Not immediately.

  • The diagnostic criteria remain the same
  • Treatment is still tailored to your specific symptoms and goals
  • Current clinical guidelines still use the term PCOS

The transition to PMOS is expected to be gradual, with both terms used together for some time.

Why this matters for women's health

While a name change might seem small, it can have a meaningful impact. A more accurate name aims to:

  • Improve earlier diagnosis
  • Encourage whole-person care, beyond reproductive health
  • Reduce stigma and misunderstanding
  • Increase awareness of long-term metabolic health risks

What this means at Belle Women's Health

At Belle, this shift reflects how we already approach care. We don't treat PCOS (or PMOS) as just a cycle or fertility issue — we take a broader, holistic view of your health, including:

  • Hormonal balance
  • Metabolic health
  • Skin and lifestyle factors
  • Mental wellbeing
  • Symptom control
  • Fertility goals

This is what holistic women's healthcare means in practice.

This condition has always been more than just ovaries — and now the name is starting to reflect that.

If you're experiencing symptoms such as irregular cycles, acne, hair changes, difficulty with weight, or concerns about fertility, you're not alone — and there are evidence-based ways we can support you.
