What is Polycystic ovary syndrome (PCOS)?
Polycystic ovary syndrome (PCOS) is a common hormonal condition affecting how the ovaries work, often involving irregular or absent ovulation, higher levels of androgens (male hormones), and small fluid-filled sacs on the ovaries.
Common symptoms include irregular or absent periods, difficulty conceiving, excess hair growth, acne, and weight gain. PCOS is also linked to a higher risk of insulin resistance and type 2 diabetes, so management often addresses both symptoms and longer-term health.

Practical steps
Take these self-care steps
These measures can help ease symptoms, support recovery, and reduce the chance of things worsening — but they don't replace medical advice if symptoms are severe or persistent.
- 1Focus on a balanced diet.Managing blood sugar through a diet rich in fibre, protein, and whole foods can help with several PCOS symptoms.
- 2Stay physically active.Regular exercise helps improve insulin sensitivity and can support weight and symptom management.
- 3Discuss hormonal treatment options.The contraceptive pill or other hormonal treatments can help regulate periods and manage symptoms like acne and excess hair growth.
- 4Ask about fertility support if trying to conceive.Specific treatments can help support ovulation if you're trying to become pregnant.
- 5Get regular health monitoring.Since PCOS is linked to increased diabetes risk, periodic blood sugar and cholesterol checks are worthwhile.

BarnMD Bottom Line
PCOS affects everyone differently, but with the right combination of lifestyle changes and treatment, symptoms can be well managed long-term.
Managing insulin resistance through diet and exercise often improves several PCOS symptoms at once, not just weight.
