Understanding Polyendorcine Metabolic Ovarian Syndrome (PMSO) PCOS

PCOS is now being recognised by a new name: polyendocrine metabolic ovarian syndrome (PMOS). The change follows 11 years of international research and 'intentionally' reflects a better understanding of the condition.

 PMOS affects nearly 170 million women worldwide and is about much more than the ovaries. In fact, many women diagnosed with the condition do not have ovarian cysts at all, but instead experience a cluster of symptoms affecting many areas of health

 Experts now understand that it is a complex endocrine (hormonal) and metabolic condition that can affect many systems throughout the body, with ovarian symptoms being just one part of it.

 PMOS develops over time and affects each woman differently, with the underlying cause varying from woman to woman, which is why a one-size-fits-all approach often falls short and many women are dismissed or struggle for years before receiving a diagnosis.

PMOS is emerging as a more accurate term for PCOS and every word in the name is intentional.

POLYENDOCRINE highlights the involvement of multiple hormonal systems, including insulin, androgens, and neuroendocrine hormones such as LH and FSH. This reflects that the condition extends far beyond the ovaries alone.

METABOLIC recognises the strong connection between PMOS and metabolic health, including insulin resistance, increased risk of type 2 diabetes, weight challenges, and cardiovascular disease.

OVARIAN refers to ovulatory dysfunction, where irregular or absent periods occur due to disrupted ovulation.

PMSO is a complex endocrine and metabolic condition that affects many aspects of a woman’s health. It is typically characterised by a cluster of symptoms that may occur individually or together, including:

1. Hormonal balance, menstrual cycles, and fertility

2. Endocrine and metabolic function, Increased sensitivity to stress

3. Heart and cardiovascular health

4. Skin and hair concerns, including acne, excess hair growth, and hair thinning

5. Emotional wellbeing, including anxiety, depression, and other mental health challenges

Having a clear understanding of appropriate testing and treatment options is essential, empowering you to make informed decisions and advocate for your health needs.

PMSO is not caused by a single factor.

Rather, it often develops through a combination of genetic, metabolic, environmental, and lifestyle influences.

Factors that may increase the likelihood of developing PMSO include:

Nutritional deficiencies or dietary patterns that affect metabolic health

Exposure to environmental pollutants and hormone-disrupting chemicals

Chronic stress and impaired stress response (HPA axis dysregulation)

Insufficient or poor-quality sleep

Gut microbiome imbalances and increased intestinal permeability (“leaky gut”)

Infections or chronic inflammatory processes

Thyroid dysfunction

Impaired detoxification pathways

Mycotoxin exposure (mould)

Genetic predisposition

Obesity or metabolic dysfunction

These influences can contribute to a cascade of physiological changes, including hyperinsulinaemia, oxidative stress, chronic low-grade inflammation, elevated androgens, disrupted ovarian follicle development, and irregular menstrual cycles.

Your Body Is Communicating

“You are not alone, and there is hope. Your body is never working against you.”

PMOS can often feel like an emotional rollercoaster. Hormonal changes, uncertainty, and the physical symptoms themselves can create significant stress, which may further amplify the cycle.

From a functional medicine perspective, symptoms are not viewed as random or inconvenient problems to suppress. Instead, they are signals - your body’s way of communicating that something within the system needs attention.

When we begin to listen to those signals, we can start addressing the deeper imbalances that may be driving them.

PMOS: Every Woman Is Unique

PMOS does not look the same for everyone, which is why many women are dismissed or struggle for years before receiving a diagnosis. Research increasingly recognises several phenotypes, or patterns, that reflect different underlying mechanisms.

These may overlap and evolve over time, which is why personalised assessment and treatment are essential.

Understanding which patterns may be contributing to your symptoms allows health care to be more targeted and effective.

Why PMOS Often Goes Unrecognised:

• A normal ultrasound does not rule it out - many women with PMOS do not have ovarian cysts
• Blood sugar may appear “normal” while underlying insulin issues remain undetected because fasting insulin was never checked
• PMOS can occur in lean women too, but this form is commonly overlooked
• Not everyone develops noticeable facial hair or excess hair growth, even when androgen levels are elevated
• Cycles may seem regular while ovulation is still inconsistent or absent
• Starting birth control at a young age can sometimes hide symptoms and delay recognition of the underlying metabolic condition

Alongside assessing symptoms and medical history, we use comprehensive testing to help guide personalised health care.

A Functional Medicine Approach: Addressing the Root Cause

PMOS develops over time and affects each woman differently, which is why a one-size-fits-all approach often falls short.

At LITHE Health Clinic, we take a personalised, root-cause approach that looks beyond symptom management. By understanding your health history, lifestyle, environment, and lived experiences, we aim to uncover the factors contributing to your symptoms and restore balance across the body’s systems.

As part of this process, we carefully review your test results and medical records alongside your history, symptoms, and questionnaires to create a safe, evidence-based, and individualised care plan. We also offer comprehensive advanced testing to support deeper insight into your health.

Rather than simply masking symptoms, we focus on supporting long-term healing and treating the underlying imbalances driving them. This approach has always been essential in the clinical management of PCOS.

At LITHE Health Clinic, this process may include:

Comprehensive health assessments

Advanced functional laboratory testing

In-depth interpretation of results

Nutritional therapy

Targeted supplement and nutraceutical protocols

Lifestyle and nervous system support

A supportive therapeutic partnership throughout your journey
