For decades, women have known it as Polycystic Ovary Syndrome (PCOS). Now, this complex hormonal and metabolic condition has a new name: Polyendocrine Metabolic Ovarian Syndrome (PMOS). But this is about much more than changing a name. It’s about changing the way we understand, recognise and manage a condition affecting millions of women worldwide.
A New Name for a Condition We’ve Known for Decades
If you’ve been diagnosed with PCOS, you’ve probably spent years hearing about ovarian cysts, irregular periods, fertility challenges and weight management.
But what if the name itself was never telling the whole story?
On 12 May 2026, an international group of researchers, healthcare professionals and women with lived experience announced that Polycystic Ovary Syndrome (PCOS) would officially become Polyendocrine Metabolic Ovarian Syndrome (PMOS).
The change followed years of international research, consultation and collaboration, recognising something that clinicians and women living with the condition have understood for a long time.
This condition has never been just about the ovaries.
PMOS affects approximately one in eight women worldwide, influencing hormonal function, metabolic health, reproductive health and psychological wellbeing.
For us at Overcome PMOS, this change is particularly meaningful.
Through our combined clinical experience, Evelin and I have worked with thousands of women navigating the challenges of this condition.
We’ve seen firsthand how complex and individual these challenges can be, and how important it is to look beyond isolated symptoms to understand the bigger picture.
The new name gives us an opportunity to have a more complete conversation about women’s health.
Why Was PCOS Renamed PMOS?
The original name, Polycystic Ovary Syndrome, was misleading for several reasons.
Firstly, the term “polycystic” suggested that women with the condition had abnormal cysts on their ovaries.
In reality, the small fluid-filled structures often seen on ultrasound are follicles, not the pathological cysts the name seemed to imply.
Secondly, not every woman with PCOS has polycystic ovarian morphology.
And perhaps most importantly, the original name placed too much emphasis on the reproductive system.
For many women, their experience goes far beyond irregular periods or difficulties conceiving.
It may include insulin resistance, metabolic dysfunction, increased androgen activity, changes in body composition, skin concerns and emotional wellbeing challenges.
The new name recognises that PMOS is a complex, lifelong condition involving multiple interconnected systems.
What Does PMOS Actually Stand For?
Understanding the new terminology helps explain why the change is so important.
P- Polyendocrine: More Than One Hormonal System
The word polyendocrine reflects the involvement of multiple hormonal pathways.
PMOS is commonly associated with increased androgen activity, disrupted ovulation and insulin resistance.
These interconnected hormonal processes can contribute to symptoms such as:
- Irregular or absent menstrual cycles
- Acne and oily skin
- Increased facial or body hair
- Thinning hair on the scalp
- Ovulation difficulties
- Fertility challenges
However, every woman’s hormonal profile and experience can be different.
This is why individual assessment is essential.
M- Metabolic: A Missing Piece of the Puzzle
The inclusion of metabolic is one of the most important aspects of the new name.
Metabolic health refers to how the body processes, stores and uses energy, including the regulation of blood glucose and insulin.
Insulin resistance is common in women with PMOS, although not every woman experiences it.
When the body’s cells become less responsive to insulin, the body may compensate by producing more of it.
Higher insulin levels can contribute to increased ovarian androgen production, creating a relationship between metabolic and reproductive hormone function.
Over time, PMOS can also be associated with an increased risk of impaired glucose tolerance and type 2 diabetes.
Importantly, these metabolic challenges can occur in women of all body sizes.
You do not need to be overweight to have PMOS or experience insulin resistance.
Recognising the metabolic component helps shift the conversation towards comprehensive, long-term healthcare rather than focusing solely on reproductive symptoms.
O- Ovarian: Still Important, But Not the Whole Story
The ovaries remain an important part of PMOS.
The condition can affect follicular development, ovulation, menstrual regularity and fertility.
Some women may have polycystic ovarian morphology on ultrasound, while others may not.
The key difference is that we now recognise ovarian changes as one component of a much broader condition.
S- Syndrome: Every Woman’s Experience Is Different
A syndrome is a collection of signs and symptoms that occur together.
And PMOS does not look the same in every woman.
One woman may experience irregular cycles and acne.
Another may have significant insulin resistance and metabolic concerns.
Someone else may first discover they have PMOS while investigating fertility difficulties.
Symptoms and health priorities may also change across different life stages.
This diversity is precisely why personalised care matters.
Does the New Name Change Your Diagnosis?
If you’ve already been diagnosed with PCOS, there’s no need to panic or assume you have a different condition.
PCOS and PMOS refer to the same condition.
The name has changed, but the underlying diagnosis has not.
The existing international evidence-based recommendations for diagnosis and management remain unchanged as part of the 2026 terminology update.
The transition to the new name will happen progressively across healthcare, research, education and clinical guidelines, with broader implementation planned for 2028.
You may therefore continue to see both PCOS and PMOS used during this transition.
Why This Change Matters for Women’s Health
For too long, women with PCOS have often been encouraged to focus on individual symptoms without always receiving a complete explanation of the underlying hormonal and metabolic processes.
Some have been told to lose weight.
Others have been offered treatment for irregular periods or fertility concerns.
These interventions may be appropriate for some women, but comprehensive care needs to consider the broader picture.
PMOS can involve reproductive, endocrine, metabolic and psychological health.
That means understanding the condition may require looking at insulin resistance, menstrual function, androgen activity, cardiovascular risk factors, sleep, emotional wellbeing and individual health priorities.
Treating a symptom is not always the same as understanding the wider condition.
This is where a more integrated, evidence-informed approach becomes valuable.
Can PMOS Be Managed? Absolutely.
One of the most important messages we want women to understand is that there are meaningful ways to manage PMOS and improve quality of life.
Through our combined clinical experience, Evelin and I have supported thousands of women navigating PCOS, now PMOS.
We’ve witnessed the difference that appropriate education, individualised strategies and ongoing support can make.
We’ve seen women develop a better understanding of their hormonal health, make sustainable lifestyle changes and experience improvements in their symptoms and wellbeing.
Our clinical experience reinforces an important principle: women deserve care that considers their individual needs rather than assuming one approach will work for everyone.
PMOS management may involve several interconnected areas.
1. Supporting Metabolic Health
Understanding insulin resistance and glucose regulation can be an important part of managing PMOS.
Depending on individual circumstances, strategies may include appropriate nutrition, regular physical activity, resistance training and medication when indicated.
2. Nourishing the Body
Nutrition is not about restrictive dieting or eliminating entire food groups unnecessarily.
It’s about developing sustainable eating patterns that support nutritional adequacy, metabolic health and individual wellbeing.
3. Building Strength and Supporting Movement
Regular movement, including strength training and aerobic activity, can support insulin sensitivity, cardiovascular health and overall wellbeing.
The most effective approach is one that is appropriate, enjoyable and sustainable.
4. Supporting Sleep and Emotional Wellbeing
PMOS can affect more than physical health.
Women with the condition experience higher rates of anxiety and depression, making emotional wellbeing an essential part of comprehensive care.
Sleep, psychological support and appropriate treatment deserve attention alongside hormonal and metabolic health.
5. Personalising Treatment
Some women may benefit from medical treatments to manage menstrual irregularities, androgen-related symptoms, metabolic concerns or fertility challenges.
Others may require additional support depending on their health history and goals.
The key is to combine evidence-based recommendations with individualised care.
There is no single PMOS strategy that works for every woman.
And there shouldn’t have to be.
PMOS Is Not Just a Reproductive-Age Concern
Another important part of this conversation is recognising that PMOS can have implications beyond the reproductive years.
While menstrual and fertility symptoms may change with age, metabolic and cardiovascular risk factors can remain relevant throughout life.
Women deserve ongoing healthcare that considers these longer-term concerns, including during perimenopause and after menopause.
The goal is not simply to manage symptoms today, but to support health and wellbeing over time.
A New Name. A Better Understanding. A New Conversation.
The transition from PCOS to PMOS represents an important shift in how we describe and understand this condition.
It acknowledges what many women have experienced for years: their symptoms are not isolated, and their health cannot be reduced to what is happening in their ovaries.
For Evelin and me, this new chapter reinforces why education, clinical understanding and individualised support are so important.
At Overcome PMOS, our mission is to help women better understand their hormonal and metabolic health, make informed decisions and feel empowered throughout their health journey.
We believe women deserve explanations that make sense, strategies grounded in evidence and care that considers the whole person.
Whether you’ve recently received a diagnosis or have been living with PCOS for decades, we want you to know that understanding your condition is a powerful place to begin.
The name has changed. The science continues to evolve. And the conversation about women’s health is moving forward.
Welcome to Overcome PMOS.
Understanding your hormones. Supporting your metabolism. Empowering your health.
