PCOS Has a New Name: What the Change to PMOS Means for You

Why this is more than a name change, and what it actually means for how women understand, manage and find support for their hormonal health.

If you have ever been told you have PCOS, or suspected you might, you may have come across recent news that the condition has been given a new name.

After more than a decade of global collaboration, Polycystic Ovary Syndrome (PCOS) has officially been renamed Polyendocrine Metabolic Ovarian Syndrome, or PMOS.

This change was announced in May 2026 in a landmark paper published in The Lancet, led by Professor Helena Teede at Monash University, alongside more than 50 patient and professional organisations including Verity (PCOS UK).

For many women, this shift feels deeply validating. The old name never quite reflected what they were experiencing day to day. The new name is intended to better describe what the condition actually is, and to help women receive earlier, more accurate diagnosis and care.

If you have spent years feeling dismissed, misunderstood, or unsure how to manage your symptoms, this update is worth understanding.

What PCOS Is Now Called and Why It Matters

Polycystic Ovary Syndrome has been renamed Polyendocrine Metabolic Ovarian Syndrome (PMOS).

Each part of the new name reflects something important about the condition.

Polyendocrine recognises that multiple hormonal systems are involved, not just the ovaries.

Metabolic acknowledges that the condition affects how the body uses energy, regulates blood sugar and manages weight.

Ovarian reflects that the ovaries are still part of the picture, although they are only one part of a much wider system.

Syndrome remains because the condition is a group of features that can present differently in different women.

The old name suggested that the condition was primarily about cysts on the ovaries. In reality, the small structures seen on ultrasound are not true cysts but arrested follicles.

Women with PMOS are not more likely than other women to have abnormal ovarian cysts.

This misunderstanding has had real consequences. It has contributed to missed diagnoses, fragmented care, and women being dismissed when their symptoms did not fit the expected picture.

Why the Old Name Was Holding Women Back

PCOS affects around one in eight women, or more than 170 million worldwide. Yet the World Health Organization estimates that up to 70 per cent of those affected remain undiagnosed.

There are several reasons for this.

The name focused attention on the ovaries, when the condition affects multiple systems.

Women without visible cysts on ultrasound were often told they did not have PCOS, even when other symptoms were present.

Symptoms such as fatigue, mood changes, weight changes and metabolic issues were often treated separately, rather than as part of one connected picture.

The framing reinforced a sense that the condition was purely gynaecological, when in reality it sits at the intersection of hormones, metabolism and overall wellbeing.

Many women describe years of going from one specialist to another without anyone joining the dots. The new name is intended to change that.

What This Means If You Have PMOS or Think You Might

It is important to understand that the condition itself has not changed. If you were diagnosed with PCOS, you still have the same condition. What has changed is how it is described, and hopefully how it will be recognised and treated going forward.

PMOS is now formally recognised as a whole body condition. It involves:

• Hormonal fluctuations, particularly involving androgens and insulin.

• Effects on weight, appetite and energy regulation.

• Impacts on skin, hair and menstrual cycles.

• Effects on mental health, mood and sleep.

Long term considerations for fertility, cardiovascular health and the risk of type 2 diabetes.

Seeing the condition this way often helps women make sense of symptoms that previously felt unrelated.

The Role of Hormones and Metabolism in PMOS

One of the most important shifts within the new name is the recognition of how central metabolism is to this condition.

Research suggests that around 85 per cent of women with PMOS have some degree of insulin resistance. This is true even for women who are not overweight, with insulin resistance present in roughly three quarters of lean women with PMOS.

Insulin resistance means the body needs to produce more insulin to manage blood sugar effectively. Over time, this can:

• Increase androgen production, which can worsen symptoms such as acne and excess hair growth.

• Make weight harder to manage, particularly around the middle.

• Contribute to energy dips, cravings and fatigue.

• Raise the long term risk of type 2 diabetes and cardiovascular issues.

Understanding this helps explain why nutrition, movement, sleep and stress management are so important in supporting PMOS. These areas directly influence the hormonal and metabolic systems at the heart of the condition.

Common Symptoms to Be Aware Of

PMOS can present differently in different women, which is part of what made the old name so misleading. Some common features include:

• Irregular, missed or heavy periods.

• Difficulty getting pregnant.

• Acne, oily skin or patches of darker skin.

• Excess facial or body hair, or thinning hair on the scalp.

• Weight changes, particularly around the abdomen.

• Fatigue, low mood, anxiety or brain fog.

• Strong cravings or energy crashes through the day.

You do not need to experience all of these to have PMOS. If any of this feels familiar, it is worth speaking to your GP for proper assessment.

Supporting PMOS Through Lifestyle and Behaviour Change

Medical care is an important part of managing PMOS, but lifestyle medicine plays a significant role too. The areas with the strongest evidence are often the ones that influence hormones and metabolism most directly.

Sustainable changes that can help include:

• Balanced eating patterns that include protein, fibre and healthy fats to support stable blood sugar.

• Regular movement, particularly a combination of daily activity and strength based exercise.

• Consistent sleep routines, since sleep influences appetite, hormones and recovery.

• Stress regulation, as chronic stress directly affects hormones involved in PMOS.

• Reducing all or nothing thinking around food and exercise, which often makes symptoms feel harder to manage.

None of this needs to be extreme. In fact, extreme approaches often make PMOS worse, not better.

Why Quick Fixes Rarely Work for PMOS

It is very common to look for fast solutions, especially after years of feeling frustrated.

However, restrictive diets, overtraining and rigid routines tend to add stress to a system that is already sensitive to it.

This can lead to:

• Increased cravings and rebound eating.

• Higher stress hormones, which can worsen symptoms.

• Cycles of starting and stopping that feel demoralising.

• Greater difficulty maintaining any progress long term.

Sustainable change works far better for PMOS. Small, repeatable habits, built gradually, are what tend to create real improvements in energy, weight, mood and cycle regularity over time.

How Health Coaching Can Help with PMOS

Managing PMOS often involves several areas of life at once, which can feel overwhelming without guidance. This is where coaching can make a meaningful difference.

As a GP and Health Coach, I support women in understanding their hormonal and metabolic health and building realistic routines that fit their life. This combines medical understanding with practical, behaviour focused coaching.

Working together with a PCOS coach or women's hormone health coach can help you:

• Make sense of your symptoms and how they connect.

• Build sustainable nutrition, movement, sleep and stress habits.

• Reduce overwhelm and all or nothing thinking.

• Feel more in control of your health rather than at the mercy of your symptoms.

Create a long term approach that supports your hormones, metabolism and overall wellbeing.

The focus is never on quick fixes or restriction. It is on creating an approach that genuinely fits your life and supports your health over time.

A New Name, a New Conversation

The change from PCOS to PMOS is more than a label. It reflects a shift in how this condition is understood, taught and treated, and it acknowledges what women have been describing for a long time.

If you have PMOS, or suspect you might, this is a hopeful moment. The conversation around the condition is finally catching up with the reality of how it affects daily life.

With the right support, PMOS can be managed in a way that feels calm, structured and sustainable. You do not need to navigate it alone, and you do not need to overhaul your life overnight.

If you are looking for personalised support to manage PMOS in a way that fits your life, coaching can help you build the habits, mindset and routines to feel more like yourself again.

Frequently Asked Questions

Is PCOS the same as PMOS?

Yes. PMOS (Polyendocrine Metabolic Ovarian Syndrome) is the new name for the condition previously called PCOS. The condition is the same, but the name has been updated to better reflect its hormonal and metabolic nature.

Do I need a new diagnosis if I already have PCOS?

No. If you have already been diagnosed with PCOS, you do not need to be reassessed. Your diagnosis stands, simply under a new name.

Why was the name changed?

The old name suggested the condition was mainly about ovarian cysts, which is inaccurate. The new name reflects that PMOS involves multiple hormonal and metabolic systems and is not limited to the ovaries.

Can PMOS be managed without medication?

Many women see meaningful improvements through lifestyle changes alone, particularly around nutrition, movement, sleep and stress. In some cases, medication is also helpful. A personalised approach with your GP and a health coach can help you decide what is right for you.

How can a health coach help with PMOS?

A health coach can help you build sustainable habits, understand how your symptoms connect, and create routines that support your hormones and metabolism in a realistic, manageable way.
