Hi, I’m Cyster.
Ask me anything about PMOS, formerly PCOS, or tell me what you’ve been noticing. I answer in plain language, show how settled the evidence is, and help you build a Read for your clinician.
I can’t diagnose you or tell you what to take. I can help you understand the landscape and walk in prepared.
In May 2026, PCOS was formally renamed PMOS, polyendocrine metabolic ovarian syndrome, through a global consensus published in the Lancet.
The old name was retired because it was misleading. The condition isn’t really about cysts, and it isn’t only about the ovaries.
The new name reflects what it actually is: several hormone systems plus a real metabolic component, not just a reproductive issue.
They can be. Cycle changes and jawline acne are two things clinicians often look at together when they’re thinking about androgen patterns in PMOS.
I can’t tell you what’s behind yours, that’s a conversation for your clinician, but it’s worth raising them as a pair rather than as two separate complaints.
I’ve added both to your Read, with a question you can bring in.

Cyster is educational and care-prep, never diagnosis or treatment. Answers are grounded in a curated evidence base and labelled by how settled the science is. Cyster does not know your full history and cannot tell you what you have or what to take. For anything about your own diagnosis or care, talk to a clinician. If something feels urgent, or you are thinking about harming yourself, contact a clinician now or your local emergency services.
