For years, women were told that PCOS was mainly an ovarian condition.
Irregular periods.
“Cysts” on the ovaries.
Difficulty getting pregnant.
But many women living with the condition knew there had to be more to the story.
The exhaustion.
The cravings.
The stubborn weight gain.
The anxiety.
The inflammation.
The brain fog.
The feeling that their body was constantly working against them.
And now, after years of international collaboration between researchers, clinicians, and patient advocacy groups, PCOS has officially been renamed:
PMOS — Polyendocrine Metabolic Ovarian Syndrome
This new name was announced in 2026 following a global consensus process involving more than 50 professional and patient organisations.
And honestly, I believe this shift matters deeply for women.
Because this condition was never just about ovaries.
Why the old name was a problem
The term “polycystic ovary syndrome” has confused women and healthcare providers for decades.
Many women diagnosed with PCOS do not actually have ovarian cysts.
And many women with ovarian cysts do not have the syndrome.
The name focused attention on one small piece of a much bigger picture.
Meanwhile, women were often struggling with:
- insulin resistance
- blood sugar instability
- chronic inflammation
- fatigue
- mood changes
- skin and hair symptoms
- difficulty managing weight
- cardiovascular risk
- fertility challenges
- sleep issues
- metabolic dysfunction
But these symptoms were frequently treated separately instead of being recognised as connected.
The new name — PMOS — reflects what research has increasingly shown:
This is a complex hormonal and metabolic condition affecting the whole body.
What does PMOS actually mean?
Polyendocrine
Multiple hormone systems are involved.
This includes communication between the brain, ovaries, adrenal glands, insulin pathways, and other hormonal systems.
Metabolic
This condition affects metabolism and insulin regulation.
Many women with PMOS experience insulin resistance — including women in smaller bodies.
This can impact:
- appetite
- cravings
- energy
- fat storage
- inflammation
- cholesterol
- long-term cardiovascular health
Ovarian
The ovaries are still part of the picture — but they are no longer seen as the whole story.
The ovarian symptoms are one expression of a larger systemic condition.
Why this matters in midlife
I think this conversation is especially important for women in their 40s and 50s.
Because many of the symptoms women experience in perimenopause overlap with PMOS:
- weight changes
- poor sleep
- fatigue
- insulin resistance
- increased abdominal fat
- anxiety
- inflammation
- low mood
- cravings
- feeling disconnected from their body
And too often, women blame themselves.
They think:
“I must not be disciplined enough.”
“I just need more willpower.”
“I need to eat less.”
But many women are dealing with complex hormonal and metabolic changes that deserve support — not shame.
What women need instead
In my work, I see so many women trying to “fix” their body through stricter dieting and more control.
But often, the body responds better to support than punishment.
That support may include:
- stabilising blood sugar
- eating enough protein and fibre
- reducing nervous system stress
- improving sleep quality
- building muscle safely
- supporting emotional wellbeing
- reducing all-or-nothing thinking around food
- creating consistency instead of perfection
Not fighting the body.
Learning to work with it.
The bigger shift happening in women’s health
To me, the move from PCOS to PMOS represents something much bigger.
Women’s health is finally beginning to move away from oversimplified labels and toward understanding the body as an interconnected system.
Hormones affect metabolism.
Stress affects hormones.
Sleep affects insulin.
Inflammation affects energy and mood.
Everything is connected.
And women deserve care that reflects that complexity — with more understanding, more compassion, and far more support than they have often received in the past.
