PCOS to PMOS:

The term “Polycystic Ovary Syndrome” has long been criticised by clinicians and researchers because it does not accurately describe the full scope of the condition.

Despite its name:

• Not all women with PCOS have ovarian cysts

• Symptoms often extend far beyond reproductive health

• The condition significantly impacts metabolism, hormones, cardiovascular health, and insulin function

• Many patients experience delayed or missed diagnoses due to misconceptions

The new term, Polyendocrine Metabolic Ovarian Syndrome (PMOS), offers a broader and more medically accurate description.

PMOS reflects that the condition involves:

• Hormonal imbalance across multiple endocrine systems

• Insulin resistance and metabolic dysfunction

• Irregular ovulation

• Fertility challenges

• Increased long-term risks such as type 2 diabetes, heart disease, and obesity

This reclassification helps healthcare professionals move away from a narrow reproductive focus and towards a more holistic understanding.

Dr Nikoletta Panagiotopoulou, our Consultant Gynaecologist and Fertility Specialist, explains:

"Personalised care is so important for conditions like PMOS because no two people experience it in the same way. 

PMOS stands for polyendocrine metabolic ovarian syndrome but, although the name may be shared, the symptoms, concerns and day-to-day impact can be very different from person to person. Some people may notice irregular periods or difficulties with ovulation, others may struggle with weight changes, acne, excess hair growth, or low energy. For many, PMOS can also affect confidence, mood and overall wellbeing.

A personalised approach means taking the time to understand each individual woman - not just their diagnosis. This involves looking at hormone patterns, menstrual cycles, metabolic health, lifestyle, and future plans, whether that’s improving symptoms now, planning for pregnancy, or protecting long-term health. It also recognises that what works well for one person may not be right for another.

Personalised care allows treatment to be tailored to individual goals and preferences, rather than relying on a standard plan. This might include lifestyle support, cycle management, fertility care, or help with symptoms that affect how women feel day to day. Just as importantly, it means ongoing support, as needs change over time.

Ultimately, personalised care helps women feel listened to, understood and supported - and gives women the best chance of managing PMOS in a way that fits their life, not the other way around."

The transition from PCOS to PMOS represents more than a name change — it signals a major shift in how women’s health conditions are understood and treated.

By recognising the condition as a multi-system disorder rather than simply an ovarian issue, patients can benefit from:

• More accurate diagnoses

• Broader treatment strategies

• Improved long-term outcomes

• Greater awareness of whole-body health

With better awareness comes better diagnosis and more effective long-term care.
