If you’ve spent any time on TikTok or Instagram lately, you may have seen people talking about PMOS.
No, it’s not a new condition. The term PMOS (Poly-Metabolic Ovary Syndrome) is a more accurate name for what we knew as PCOS (Polycystic Ovary Syndrome).
Here’s the thing: this name has always been a little misleading.
Many people diagnosed with PMOS don’t actually have ovarian cysts (they’re technically small follicles, not cysts), while others do have these follicles but don’t have PMOS. The name also focuses entirely on the ovaries, but the condition actually affects so much more than just reproductive health.
For many women, PMOS is linked to insulin resistance, inflammation, hormone imbalances and an increased risk of conditions like type 2 diabetes and heart disease. It’s a whole-body condition, not just an ovarian one.
Poly-Metabolic Ovary Syndrome better reflects what’s happening in the body.
“Poly-metabolic” highlights the fact that metabolism plays a significant role for many people with the condition. While symptoms vary from person to person, PMOS is often associated with issues like insulin resistance, changes in cholesterol, weight fluctuations and an increased risk of metabolic disease.
It’s a reminder that treating PMOS isn’t just about managing periods or fertility, it’s about supporting long-term health.
One of the biggest misconceptions about PMOS is that everyone experiences the same symptoms. Actually, that couldn’t be further from the truth.
Some women have irregular or absent periods. Others struggle with acne, excess facial or body hair, scalp hair thinning or difficulty falling pregnant. Some gain weight, while others have a lean body type and still meet the criteria for PMOS.
Because symptoms can vary so much, diagnosis isn’t always easy, and many women spend years wondering why they don’t feel quite right.
PMOS affects around 1 in 10 women, making it one of the most common hormonal conditions in Australia. But, remarkably, many women don’t receive a diagnosis until they’re trying to conceive or their symptoms become difficult to ignore.
The earlier it’s recognised, the sooner you can understand what’s happening in your body and access the right support.
There’s no single treatment for PMOS because it can affect individuals so differently. Management may include lifestyle changes, nutritional support, medications to improve insulin sensitivity or regulate hormones, and fertility treatments if pregnancy is part of the plan.
We think it’s more important to look at the bigger picture instead of treating individual symptoms in isolation.
PMOS is officially the new name that better reflects the condition – so yes, it’s the best name.
If you’ve been experiencing irregular periods, ongoing acne, unexplained weight changes, excessive hair growth or fertility concerns, it’s worth speaking with your women’s health GP or women’s health specialist.
