PCOS symptoms and treatment UK: diagnosis and care options
Polycystic ovary syndrome explained — symptoms, how PCOS is diagnosed in the UK, and treatment for periods, skin, weight and fertility.
PCOS is often self-diagnosed from internet lists — but overlapping conditions exist. Proper assessment prevents years of wrong assumptions.
Core features of PCOS
Two of three are typically required for diagnosis:
- Irregular or absent periods (infrequent ovulation)
- Signs of high androgens — acne, excess hair, blood test results
- Polycystic ovary appearance on ultrasound
Treatment depends on your priority
Regulate periods: Combined or progestogen contraception.
Improve acne/excess hair: Contraception, anti-androgen treatments, topical acne care — see our acne guide.
Weight management: Diet, exercise, sometimes metformin — weight programmes where clinically appropriate.
Trying to conceive: Specialist fertility referral — not managed through emergency online pathways.
Lifestyle foundations
- Low-GI balanced meals
- Regular resistance and cardio exercise
- Sleep and stress management
- Track cycles to understand patterns

Frequently asked questions
What are the main symptoms of PCOS?
Irregular periods, excess hair growth, acne, weight gain and difficulty conceiving are common — but not everyone has all features.
How is PCOS diagnosed?
By combining irregular ovulation signs, elevated androgens (symptoms or blood tests) and ultrasound appearance of ovaries — after excluding other causes.
Can PCOS be treated online?
Repeat contraception for cycle regulation and some ongoing care may be managed online. Full diagnosis and fertility treatment usually need GP or specialist review.
Does PCOS cause weight gain?
PCOS is linked to insulin resistance in many women, making weight management harder — but lifestyle changes and medical support still help.
