A New Name for an Old Condition: Why PCOS Is Now PMOS

September 01, 2026

If you've been diagnosed with — or suspect you have — Polycystic Ovary Syndrome (PCOS), you may have seen the recent news: the condition has a new name. As of May 2026, a global consensus of clinicians, researchers, and patient advocates officially renamed PCOS to Polyendocrine Metabolic Ovarian Syndrome, or PMOS.

This wasn't a rebrand for the sake of it. The term "polycystic" was always part of the problem — it implies that ovarian cysts are central to the diagnosis, when in reality, many people with this condition don't have ovarian cysts at all. The old name also obscured just how much this condition affects the whole body — metabolism, hormones, skin, mood, and more — not just the ovaries.

The new name, PMOS, better reflects what we've always treated naturopathically: a complex, multisystem hormonal and metabolic condition, not simply a reproductive or ovarian issue.

At Origins Integrative Health, we'll be using the term PMOS going forward, and you may notice this terminology rolling out gradually across patient materials, labs, and guidelines over the next few years. The science and our approach to care haven't changed — just the language now matches what we've always known to be true.

What Is PMOS?

PMOS (formerly PCOS) is one of the most common endocrine disorders affecting individuals of reproductive age — impacting an estimated 1 in 8 women globally. Despite how common it is, PMOS is frequently underdiagnosed and misunderstood. PMOS is a complex hormonal and metabolic condition characterized by irregular ovulation, androgen excess (elevated male hormones), and polycystic-appearing ovaries on ultrasound. However, you don't need to have ovarian cysts to be diagnosed with PMOS.

According to the Rotterdam Criteria (the most commonly used diagnostic guidelines), a person must meet two of the following three criteria for a PMOS diagnosis:

Irregular or absent ovulation (oligo- or anovulation)
Elevated androgen levels (via bloodwork or symptoms like acne or hirsutism)
Polycystic-appearing ovaries on ultrasound

The 4 Types of PMOS

Not all PMOS is the same. Understanding the subtypes can help target treatment more effectively. The following types are not formally recognized in diagnostic manuals but are commonly used in functional and integrative medicine:

Insulin-Resistant PMOS

Most common type
Driven by high insulin levels, often associated with weight gain, fatigue, and sugar cravings
May improve with blood sugar regulation strategies
Research: Insulin resistance is a key feature in up to 75% of individuals with PMOS (PubMed)

Post-Pill PMOS

Occurs after discontinuing hormonal birth control
Periods may stop or become irregular
Usually temporary (can resolve within 6–12 months)

Inflammatory PMOS

Characterized by chronic low-grade inflammation
May present with fatigue, joint pain, skin conditions (like eczema), or digestive issues
Elevated inflammatory markers like CRP may be present (PubMed)

Adrenal PMOS

Driven by stress and overproduction of adrenal androgens like DHEA-S
Bloodwork may show normal testosterone but elevated DHEA-S
More common in lean individuals (PubMed)

Common Symptoms of PMOS

PMOS symptoms vary, but may include:

Irregular or absent periods
Cystic acne
Unwanted facial or body hair (hirsutism)
Thinning hair or hair loss on the scalp
Weight gain or difficulty losing weight
Mood changes or anxiety
Infertility or trouble ovulating
Fatigue or blood sugar imbalances

It's important to note that PMOS can affect people of all body sizes — you do not need to be overweight to have PMOS.

The Role of Naturopathic Medicine in PMOS

Naturopathic medicine looks beyond symptom management to identify and address root causes of hormone imbalance. We may evaluate:

Blood sugar and insulin levels (fasting insulin, HOMA-IR, glucose tolerance test)
Inflammatory markers (CRP, ESR)
Adrenal function (DHEA-S, cortisol patterns)
Nutrient deficiencies (e.g., magnesium, B vitamins, vitamin D, inositol)
Gut health and microbiome imbalances, which have been linked to PMOS in recent research (PubMed)

One of the key drivers of PMOS is insulin resistance, which occurs in up to 75% of individuals — even those who are not overweight. Elevated insulin can increase testosterone, disrupt ovulation, and contribute to symptoms. Other contributing factors may include inflammation, gut microbiome imbalances, stress, and post-birth control hormone shifts.

Emerging Research: What's New in PMOS?

Gut Microbiome & PMOS: Studies suggest that people with PMOS may have reduced gut microbial diversity, which can impact inflammation, insulin sensitivity, and hormone metabolism. Probiotics and dietary fiber may help improve symptoms. (PubMed)

Inositol Supplements: A growing body of evidence supports the use of myo-inositol and D-chiro-inositol to improve insulin sensitivity, ovulation, and fertility outcomes. (PubMed) Anti-inflammatory and Mediterranean diets: Diets rich in anti-inflammatory foods — like leafy greens, berries, fatty fish, and olive oil — have shown promise in reducing symptoms, especially in inflammatory and insulin-resistant PMOS. (PubMed)
