This Condition Affecting 170 Million Women Just Got Renamed

You Should Know: Polycystic ovary syndrome, more commonly known as PCOS, just got a new name. The condition, which affects about one in eight women worldwide (that’s roughly 170 million people), is now officially called PMOS, or polyendocrine metabolic ovarian syndrome. The rebrand emerged from a 14-year global effort involving more than 50 patient and professional organizations, with findings published in The Lancet this month.

Going Deeper: The old name was causing real confusion because many people suffering from “polycystic ovary syndrome” don’t even have ovarian cysts. PMOS can cause hormonal and metabolic disruption, with symptoms like irregular periods, acne, excess body hair, weight changes, and higher risks for type 2 diabetes and heart disease. So that cyst-focused framing of the past led to delayed diagnoses and frustration for patients whose symptoms and concerns weren’t taken seriously.

Takeaway: The new name is meant to signal to doctors and patients that this is a whole-body condition rooted in endocrine and metabolic dysfunction, not just a reproductive issue.

Bottom Line: PCOS is now PMOS, and the goal is getting people faster, more accurate care.
