PCOS to PMOS

If you've been diagnosed with PCOS or suspect you might have it there's something important you need to know. 

On May 12, 2026, a landmark global consensus paper officially renamed polycystic ovary syndrome (PCOS) to Polyendocrine Metabolic Ovarian Syndrome (PMOS). 

Let's talk about why this matters  and what it means for the millions of women navigating this condition.

The old name was always misleading. The name "polycystic ovary syndrome" was never quite right to begin with since the term implies that pathological ovarian cysts are a defining feature of the condition, but they're not. Many women with PCOS never have cysts on their ovaries at all. Many women with ovarian cysts don't have PCOS. The name created confusion for patients and clinicians.

The old PCOS name contributed to:

1. Delayed diagnosis - up to 70% of women with this condition remain undiagnosed

2. Fragmented care - clinical focus stayed on the ovaries instead of the full hormonal and metabolic picture

3. Patient distress - many women reported emotional distress specifically around the name itself

4. Research gaps - the narrow name complicated research funding and healthcare coding

The new name, Polyendocrine Metabolic Ovarian Syndrome, actually reflects what's happening in the body. Let's break it down:

1. Polyendocrine: This condition involves multiple hormones, including insulin, androgens, and ovarian hormones. 

2. Metabolic: Insulin resistance is present in 85% of people with PMOS,  including 75% of lean women. Metabolic dysfunction is central to what's driving symptoms.

3. Ovarian: Yes, the ovaries are involved, but they're not the whole story.

This is a multisystem condition, not just a reproductive one. 

PMOS has polygenic origins spanning neuroendocrine, metabolic, and reproductive pathways. Women with PMOS can experience insulin resistance, elevated androgens, increased risk of heart disease, heart attack, and stroke, as well as higher rates of depression, anxiety, acne, and hair loss. 

When we understand it as a systems-level condition, we can begin to address it that way.

What This Means For You

Whether you're newly diagnosed, have been managing PCOS for years, or are still searching for answers to a cluster of symptoms that haven't been explained, this renaming is an invitation to look at the full picture.

If you suspect PMOS, here are the tests we run with our clients to understand the full picture: 

1. Comprehensive blood work including key metabolic markers: HbA1c, fasting glucose, fasting insulin, lipid panel, hs-CRP, homocysteine, uric acid, GGT, and vitamin D. Because PMOS is a metabolic condition at its core, these markers give us a baseline picture of how the body is processing glucose, lipids, and managing inflammation.

2. Hormone blood work: estradiol, progesterone, FSH, LH, total and free testosterone, DHEA-S, SHBG, prolactin, AMH, and a full thyroid panel. 

3. DUTCH testing provides a deeper layer of insight into hormone metabolism, particularly for androgen imbalances. Rather than just showing hormone levels, the DUTCH test maps out androgen and estrogen metabolites and preferred metabolic pathways, so we can see not just how much of a hormone you have, but how your body is processing and clearing it.

4. GI Map helps us identify underlying drivers of metabolic imbalance that are often overlooked in conventional PMOS care. Low beneficial bacteria, especially Akkermansia, a keystone species for metabolic health and blood sugar regulation. Opportunistic overgrowths can also drive inflammation and metabolic stress can all show up here and directly impact how the body manages hormones.

These are the exact panels we run with clients navigating PMOS symptoms, because we know that to truly address this condition, you have to zoom out and look at all the systems.

Our Approach to PMOS

At The Funk'tional Nutritionist, this renaming aligns with everything we've been doing with our clients for years. 

Symptoms like irregular cycles, acne, hair loss, weight struggles, fatigue, and mood changes don't exist in isolation, and they don't have a single fix. They are messages from a body that needs support across multiple systems.

When we work with clients navigating PMOS, we're looking at blood sugar regulation, hormone detoxification, gut health, adrenal function, inflammation, and nutrition because all of these pieces are connected.

If you are looking for a comprehensive, root-cause approach to PMOS, our team of practitioners would be happy to support you. Sign up for our 1:1 Functional C.A.R.E Method™ and let's get to the root of what's going on in your body.
