What Is PMOS? or What is PCOS?

Understanding Polyendrocrine Metabolic Ovary Syndrome AKA Polycystic Ovary Syndrome — and how to support your hormones naturally.

PMOS is one of the most common hormonal conditions affecting women, yet up to 70% of those with PMOS remain undiagnosed.

That means millions of women are living with symptoms like irregular periods, acne, weight changes, and fertility struggles — without knowing the root cause.

What causes PMOS or PCOS?

PMOS is driven by a hormonal imbalance that affects how the ovaries work. The most common disruptions include:

  • Elevated androgen levels – hormones like testosterone and DHEA (Dehydroepiandrosterone) that are naturally present in both men and women, but may be higher than usual in PMOS

  • Insulin resistance – when the body doesn’t respond properly to insulin, causing higher insulin levels

  • Chronic inflammation – which may contribute to symptoms and longer-term health risks

These factors can interfere with ovulation and trigger a range of PMOS symptoms.

While the exact cause of PCOS is still being researched, we know that genetics often play a role, and lifestyle factors can also influence how symptoms appear and evolve.

What are the symptoms of PMOS?

PMOS doesn’t look the same for everyone. Your symptoms might shift over time, or appear in different combinations. That’s part of what makes it so difficult to diagnose — and so important to personalise your support.

You may notice:

  • Irregular, infrequent or absent periods

  • Difficulty getting pregnant due to irregular ovulation

  • Unwanted hair growth on the face, chest, or stomach

  • Persistent acne, especially around the jawline

  • Hair thinning or hair loss on the scalp

  • Unexplained weight gain or resistance to weight loss

  • Mood swings, anxiety, or low mood

  • Fatigue or low energy

Are there long-term risks?

Yes — and that’s why managing PMOS early matters. Without proper support, PMOS can increase your risk of developing:

  • Type 2 diabetes

  • Heart disease and high blood pressure

  • High cholesterol levels

  • Sleep apnoea

  • Endometrial (womb) cancer

The good news? With consistent support, many of these risks can be reduced or even prevented.

Is there a cure?

There’s currently no cure for PMOS — but there are many ways to manage it effectively. By combining lifestyle changes, nutrition, and targeted supplementation, many women experience improved cycles, energy, mood, and fertility.
