PCOS (now called PMOS): symptoms, causes & treatment
PCOS, which the NHS now calls polyendocrine metabolic ovarian syndrome (PMOS), affects around 1 in 10 UK women. Irregular periods, excess hair, acne and weight difficulty are common; diagnosis needs proper assessment.
Editorial information by Kaiser Khan. Not clinically reviewed.
Why it happens
Hormonal imbalance with higher androgens and often insulin resistance. Runs in families; not caused by ovarian cysts alone despite the name.
Treatment
Depends on goals: contraception regulates cycles; a prescriber may treat insulin resistance; fertility referral if trying to conceive; weight management where appropriate.
Self-care that helps
Regular exercise, balanced diet with low-GI choices, track cycles, and seek assessment rather than guessing from symptoms alone.
When to get help
No periods for 3+ months, signs of diabetes, or trying to conceive for 12 months (6 if over 36) — GP or specialist review.
