PCOS has a new name: what PMOS means for you
In May 2026, polycystic ovary syndrome got a new name. If you've been diagnosed with PCOS, or think you might have it, here's what the change means, and why it matters for how you're treated.
The new name: PMOS
An international consensus study published in The Lancet renamed PCOS as polyendocrine metabolic ovarian syndrome, or PMOS. The change followed many years of work between experts and patients, and is supported by a large number of medical and patient organisations.
Why change the name?
- Many women don't have cysts. The old name was confusing and led to misunderstanding.
- It's a whole body condition. It affects your hormones and your metabolism, not just your ovaries.
- It's often missed. A clearer name may help more women get diagnosed and supported earlier.
Insulin resistance, explained simply
Insulin moves sugar from your blood into your cells for energy. With insulin resistance, your cells don't respond as well, so your body makes more insulin. High insulin can make the ovaries produce more testosterone, which can worsen symptoms like irregular periods, acne, extra hair and weight changes.
- Extra insulin
- More testosterone
- More symptoms
This works in reverse too. When your blood sugar is steadier, insulin can fall, and many symptoms ease.
What this means for food
Because metabolism is at the heart of PMOS, food is one of the most powerful tools you have. That means reducing refined carbs and sugar, choosing slower release carbs, and building meals around protein, fibre and healthy fats. It isn't about strict diets, it's about steadier blood sugar.
