PCOS is Now PMOS: What the Name Change Means for You
If you've recently heard that Polycystic Ovary Syndrome (PCOS) has been renamed Polymetabolic Ovary Syndrome (PMOS), you might be wondering why.
Don't worry, this doesn't mean it's a new condition. It simply reflects what we've learnt over many years of research and gives the condition a name that better describes what's actually happening in the body.
Why has the name changed?
The old name, Polycystic Ovary Syndrome, could be quite misleading.
Many people assumed that:
You must have cysts on your ovaries to have PCOS.
The ovaries are the main problem.
It only affects fertility.
In reality, none of these are necessarily true.
Many people diagnosed with PCOS don't have cysts on their ovaries, while others who do have "polycystic" appearing ovaries don't actually have PCOS.
The tiny "cysts" seen on an ultrasound aren't true cysts at all. They are actually small follicles (tiny sacs that contain immature eggs) that haven't developed and ovulated as expected.
The new name, Polymetabolic Ovary Syndrome (PMOS), better reflects that this condition affects much more than just the ovaries. It recognises that hormones, metabolism, insulin, and reproductive health are all interconnected.
What is PMOS?
PMOS is a common hormonal condition that affects around 1 in 10 women and people assigned female at birth during their reproductive years.
It can affect:
Menstrual cycles
Ovulation and fertility
Hormone levels
Skin and hair
Weight regulation
Blood sugar control
Long-term health
Everyone experiences PMOS differently. Some people have only mild symptoms, while others experience significant impacts on their daily life.
What are the symptoms?
Symptoms can include:
Irregular or absent periods
Difficulty becoming pregnant due to irregular ovulation
Acne that persists beyond the teenage years
Increased facial or body hair growth
Thinning hair on the scalp
Weight gain or difficulty losing weight
Darkened areas of skin, particularly around the neck or underarms
Fatigue
Mood changes
Not everyone experiences every symptom, which is why assessment by a healthcare professional is important.
The change from PCOS to PMOS isn't about creating a new diagnosis, it's about using a name that better reflects what we now know.
This condition is about far more than the ovaries. It's a whole-body hormonal and metabolic condition that can affect many aspects of health, but with the right support, symptoms can often be managed very successfully.
If you're experiencing irregular periods, ongoing acne, excess hair growth, difficulty falling pregnant, or you've been wondering whether your symptoms could be related to PMOS, speak with your GP. Early assessment and support can make a real difference.
