PCOS Is Now Called PMOS: Why the Name Change Matters

Today, Polycystic Ovary Syndrome (PCOS) officially has a new name: Polyendocrine Metabolic Ovarian Syndrome (PMOS).

And honestly? This feels like a really significant moment.

Because for years, many women living with PCOS have said the same thing:

“The name doesn’t make sense.”

And they were right.

Despite the name, PCOS is not actually defined by ovarian cysts. In fact, the “cysts” seen on ultrasound are not true cysts at all - they are immature follicles surrounding the eggs within the ovaries.

Many women with PCOS don’t have polycystic appearing ovaries. And many women without PCOS do.

Which is why the conversation around changing the name has been building for years - and why this moment matters.

My honest thoughts about the PCOS name change

I’ll be honest - when I first heard the name was officially changing, I initially felt a bit conflicted.

As healthcare professionals, advocates and patients, we’ve worked incredibly hard over the years to build awareness around PCOS. And it’s felt like we were finally starting to make progress.

So part of me worried:

• Will this create more confusion?

• Will newly diagnosed women struggle to find information or support?

• Will people even realise PMOS and PCOS are the same condition?

  
  

And truthfully, I think there probably will be a transition period where things feel a little confusing.

But the more I reflected on it - and the more I read about the process behind the name change - the more I understood why this shift matters.

Because the old name never truly represented the full extent of the condition.

This wasn’t a quick or superficial rebrand either.

The international consensus process behind the name change was published in The Lancet and involved:

• more than 22,000 survey responses from patients and healthcare professionals globally

• 56 organisations across world regions

• 14 years of international research and collaboration

• and 86% of patients supporting a name change

  
  

And ultimately, Polyendocrine Metabolic Ovarian Syndrome (PMOS) is far more representative of what this condition actually is: A complex reproductive, hormonal and metabolic syndrome that affects far more than just the ovaries.

It will take time for awareness, language and healthcare systems to catch up.

But hopefully this is the beginning of a shift towards better understanding and more accurate conversations around the condition.

Why the old PCOS name has been problematic

The term “Polycystic Ovary Syndrome” places the focus almost entirely on the ovaries.

But PCOS has always been far more complex than that.

It is a reproductive, hormonal and metabolic condition that can affect the entire body.

Depending on the individual, PCOS symptoms may include:

• Irregular or absent periods

• Difficulty ovulating

• Fertility challenges

• Acne

• Excess hair growth

• Hair thinning

• Insulin resistance

• Food cravings

• Fatigue

• Sleep disturbances

• Anxiety and low mood

• Weight changes

• Digestive symptoms

• Brain fog

  
  

And yet many women have been told things like:

“You can’t have PCOS because you don’t have cysts.”

Or:

“Your scan was normal so everything is fine.”

The name itself has contributed to confusion for years - both for patients and healthcare professionals.

PCOS (now called PMOS) is not just about fertility

One of the biggest problems with the old name is that it minimised the metabolic side of the condition.

For many women, insulin resistance plays a major role in their symptoms.

Insulin resistance can contribute to:

• Increased androgen production

• Irregular cycles

• Cravings and appetite changes

• Fatigue

• Increased inflammation

• Difficulty regulating blood sugar

  
  

And yet many women are never told this.

Instead, they’re often given vague advice to:

• “just lose weight”

• “eat less sugar”

• or “go back on the pill”

  
  

without ever being helped to understand what’s actually happening in their body.

That’s why I hope this name change helps move the conversation beyond just ovaries and fertility.

Because PCOS (now PMOS) impacts so much more than reproductive health alone.

What I hope changes next

A new name alone won’t solve the issues women with PCOS/PMOS still face.

We still need:

Better education

Many women are still turning to TikTok and social media for information because they leave appointments feeling unsupported or confused.

Women deserve evidence-based, compassionate care that helps them understand their condition without fear or shame.

Less focus on weight alone

Women of all body sizes can have PCOS/PMOS.

And improving symptoms is about far more than simply chasing weight loss.

Many women need support with:

• blood sugar regulation

• stress management

• sleep

• movement

• relationship with food

• inflammation

• nourishment

• emotional wellbeing

  
  

More holistic support

PCOS/PMOS affects both physical and mental health.

The anxiety, body image struggles, food guilt and burnout that many women experience deserve to be taken seriously.

Women shouldn’t have to wait until they’re trying to conceive before receiving support.

The most important thing to know

Whatever this condition is called moving forward, your experience is valid.

If you’ve spent years feeling dismissed, exhausted, confused, or like your body was working against you… you are not imagining it.

And importantly: There is support available.

Managing PCOS/PMOS does not have to mean perfection. It does not have to mean cutting out every food you enjoy. And it does not have to consume your life.

Small, sustainable changes can make a huge difference.

And my hope is that this next chapter - including a new name - leads to better conversations, better care, and women feeling understood much sooner.

FAQs About The PCOS Name Change

What is the new name for PCOS?

The new name for PCOS is Polyendocrine Metabolic Ovarian Syndrome (PMOS).

Why did PCOS change its name?

The name was changed because “Polycystic Ovary Syndrome” did not accurately represent the complexity of the condition. Many women with PCOS do not have ovarian cysts, and the condition affects metabolic, hormonal and reproductive health.

Are PMOS and PCOS the same condition?

Yes. PMOS is the new name for the condition previously known as PCOS.

Why was the old PCOS name considered problematic?

The term “PCOS” focused heavily on ovarian cysts, despite the condition involving much broader hormonal and metabolic dysfunction.

Will the diagnostic criteria for PCOS/PMOS change?

At the moment, the name change does not necessarily mean the diagnostic criteria will change.

However, the new name aims to better reflect the broader hormonal and metabolic nature of the condition.
