PCOS Officially Has a New Name: PMOS

This morning, I opened Instagram and immediately noticed something unusual.

My entire professional feed was saturated with announcements from leading medical journals, reproductive endocrinologists, hormone specialists, and women’s health organizations all talking about the same thing: PCOS officially has a new name.

And when I realized this happened TODAY, I genuinely felt elated.

I literally jumped up and ran to tell my partner, “I WAS RIGHT!”

For years, I have been telling my patients that I believed the name PCOS would eventually change. I honestly thought it would happen decades from now, not this soon. So yes, I was feeling a little smug this morning. But more than that, I felt deeply happy. Happy for myself, happy for my patients, and happy that medicine is finally beginning to catch up to what so many of us working closely with this condition have understood for years.

The condition formerly known as Polycystic Ovary Syndrome, or PCOS, has officially been renamed Polyendocrine Metabolic Ovarian Syndrome, or PMOS.

And honestly? I absolutely love the new name.

What Is PMOS?

PMOS, formerly called PCOS, is a complex endocrine and metabolic condition that affects approximately 1 in 8 women worldwide. It is far more than a “period problem” or a fertility condition.

PMOS can affect:

• Insulin signaling and blood sugar regulation

• Ovulation and menstrual cycles

• Testosterone and androgen levels

• Skin health, including acne and abnormal hair growth (or hair loss)

• Mood and mental health

• Weight and metabolism

• Fertility

• Cardiovascular health

• Inflammation

• Sleep

• Liver health

The new consensus paper emphasizes that this condition is fundamentally multisystem in nature, meaning it affects multiple hormonal and metabolic pathways throughout the body.

Which is exactly why the old name never fully made sense.

How Is PMOS Diagnosed?

The diagnostic criteria themselves have not changed yet, only the name.

Currently, PMOS is diagnosed using what were previously called the Rotterdam Criteria. According to the international guidelines, adults are diagnosed when they meet at least two of the following three criteria after excluding other medical conditions:

1. Irregular or absent ovulation

This may show up as:

• Irregular menstrual cycles

• Missing periods

• Difficulty ovulating

• Fertility struggles

2. Signs of elevated androgens

These are often referred to as “male hormones,” although all humans produce them.

Signs can include:

• Acne

• Hirsutism or excess facial/body hair growth

• Hair thinning or hair loss

• Elevated testosterone on laboratory testing

3. Polycystic appearing ovaries on ultrasound

And this is the part that has confused everyone for years.

The “cysts” seen on ultrasound are not actually pathological ovarian cysts. They are immature follicles that have not completed normal development and ovulation. Those are completely different biological structures.

The new paper explicitly states that pathological ovarian cysts are not increased in this condition. And yet somehow this misunderstanding has persisted for decades.

Why the Name “PCOS” Has Confused Patients and Doctors for Years

I cannot even count how many times patients have told me things like:

“My doctor said I cannot have PCOS because I do not have ovarian cysts.”

Or:

“I had a cyst once when I was a teen, so my doctor diagnosed me with PCOS."

These assumptions are FALSE.

This is not a patient failure. This is a medical education failure.

Despite affecting approximately 1 in 8 women, PMOS remains profoundly underrecognized and misunderstood in many areas of medicine. Women’s health education has historically been underfunded, underprioritized, and oversimplified. And unfortunately, many physicians are still not being adequately trained to recognize or fully understand this condition.

The old name contributed to that confusion.

Doctors and patients would see the word “cyst” and naturally assume the diagnosis revolved around ovarian cysts. But PMOS is fundamentally a complex endocrine and metabolic condition involving insulin resistance, androgen excess, ovarian dysfunction, inflammation, and neuroendocrine signaling.

The ovaries are only one piece of the puzzle.

Why the Old PCOS Name Never Reflected My Experience With The Condition

Part of why this name change feels so personal to me is because I also have PMOS. If you look at my medical record, you will not see a diagnosis of PCOS/PMOS. That is because I have what for a long time has been considered an "atypical" presentation. I have a regular period every month, I do not have ovarian cysts, and my testosterone levels are "normal."

Yet I still struggled with many of the hallmark features of this condition including:

• Hair growth on my chin and jaw

• Acne - deep painful boils on my back and face

• Depression

• Blood sugar issues

It's not that I didn't try to get a diagnosis. I did! I even saw multiple providers who I knew were women's health focused - some I knew personally - but none of them had specialized training in PCOS and after my labs and ultrasound came back normal, all I got were shrugs and prescriptions for acne cream.

So how do I know I have PMOS? Because I have been researching this disorder for over a decade and have gone on to do specialized trainings in it for myself and for my patients. I diagnose it in other people all the time. I have seen the variations from human to human. I trust the people in my office who know what feels "normal" in their bodies and know when there is something not right even if medical professionals tell them they are making it up.

So many people who genuinely have this condition have historically been missed, dismissed, or overlooked simply because their bodies did not fit outdated stereotypes of what PCOS was “supposed” to look like.

What's more, I now track my ovulation patterns (not just menstruation) and I have done other testing such as AMH and insulin (a few of the tests I recommend all patients or physicians considering PMOS diagnosis do). All signs point to PMOS.

What PMOS Actually Means

The new name is: Polyendocrine Metabolic Ovarian Syndrome

And honestly, I think it reflects the condition beautifully.

Polyendocrine

This condition affects multiple hormone systems throughout the body, not just the ovaries.

Insulin, androgens, stress hormones, ovulation signaling, inflammatory pathways, and metabolic regulation are all interconnected here.

Metabolic

This part is incredibly important.

Many people still think of PMOS as primarily a fertility condition, but the metabolic component is massive. Insulin resistance is one of the central drivers for many patients and can contribute to fatigue, cravings, weight changes, inflammation, cardiovascular risk, fatty liver disease, and blood sugar dysregulation.

Including the word “metabolic” validates something patients have experienced in their bodies for years.

Ovarian

Ovulation and ovarian function still matter deeply in this condition.

But importantly, the misleading term “cyst” is finally gone.

And I could not be happier about that.

Why the New PMOS Name May Help Reduce Shame and Stigma

One of the most meaningful parts of the new consensus paper is that the authors intentionally considered stigma, emotional impact, and cultural sensitivity during the renaming process.

For many patients, the old name carried confusion and shame around fertility, femininity, body image, and reproductive identity.

I have seen how painful that can feel.

Some patients hear the word “cysts” and immediately become frightened. Others assume they will never be able to conceive. Some feel dismissed because they do not fit conventional stereotypes associated with PCOS.

Words matter. Names shape understanding.They shape policy.They shape medical education.They shape research funding. And they shape how patients understand themselves.

What the PMOS Name Change Means for Insurance, Diagnosis Codes, and Medical Records

Of course, even though the medical literature has officially adopted the new name, this transition is not going to happen overnight.

Medical systems move slowly.

It will likely take years before we see widespread updates in:

• Insurance databases

• ICD diagnostic codes

• Electronic medical charts

• Laboratory portals

• Educational materials

• Billing systems

• Medical software

The authors of the paper themselves describe this as a gradual global transition process that will unfold over several years.

So for now, patients will probably continue seeing “PCOS” on insurance paperwork and medical records for quite some time.

And honestly, after seeing this happen much faster than I predicted, maybe I should stop pretending I can accurately guess timelines.

Why I Am So Hopeful About the Future of PMOS Care

To me, this name change represents something much bigger than terminology. It reflects a broader shift toward understanding this condition more holistically, compassionately, and accurately.

For years, many patients have received a diagnosis and then been left asking: “Okay… now what?”

But don't worry - I've got you.

For quite some time now, I have been designing an online course specifically for patients navigating PMOS. My hope is to launch it in early 2027, if not sooner. And maybe, just maybe, like this name change, it will happen sooner than I expect.

Stay tuned.

Because what I want to create is not just another hormone course. I want it to be the answer to “now what?” A gentle, supportive, step by step roadmap that helps patients understand how to begin making sustainable lifestyle changes that improve their wellness from a naturopathic perspective.

Not perfection.

Not shame.

Not overwhelm.

Just compassionate guidance, education, nourishment, nervous system support, metabolic healing, and realistic tools that help people reconnect with their bodies and their communities in a healthier way.

That is the kind of care I believe patients deserve.

Why the PMOS Name Change Feels So Important for the Future of Women’s Health

For so long, patients with PMOS have been misunderstood.

They have been told their symptoms were cosmetic. That they just needed to lose weight. That their labs were “normal.” That they could not possibly have PCOS because they did not have cysts. That irregular cycles were the only thing that mattered. That fertility was the only thing that mattered.

Meanwhile, millions of people have been quietly navigating insulin resistance, inflammation, depression, acne, hair growth, exhaustion, metabolic dysfunction, fertility struggles, shame, confusion, and dismissal while carrying a diagnosis (or not!) that never fully reflected the reality of what they were experiencing.

So to me, this name change is about much more than semantics. It is about recognition.

It is about medicine finally acknowledging that this condition is complex, systemic, metabolic, endocrine, emotional, and deeply deserving of thoughtful care.

And honestly, I think patients have known that all along.

There is still a long way to go. We need better education. Better physician training. Better research funding. Better access to care. Better support after diagnosis. Better conversations around women’s health in general.

But today feels like a meaningful step in the right direction. And as someone who has both lived with this condition and cared for patients navigating it every day, I feel incredibly hopeful about where this next chapter could lead.

PMOS. I think it finally tells a truer story.
