Condition

PCOS (Polycystic Ovary Syndrome)

PCOS is diagnosed when at least two of three features are present: irregular cycles, signs of high androgens (acne, hair changes), and polycystic-appearing ovaries on ultrasound. Beneath all of them sits insulin resistance and inflammation in most women.

Common symptoms

  • Irregular, missed or very long cycles
  • Acne, oily skin, scalp hair thinning
  • Excess facial or body hair
  • Difficulty losing weight
  • Sugar cravings, energy crashes
  • Trouble conceiving

What drives it

  • Insulin resistance (most common driver)
  • Adrenal androgen excess
  • Post-pill PCOS (transient)
  • Inflammation

Testing approach

Useful testing goes beyond a single androgen panel. We look at LH:FSH ratio, total and free testosterone, SHBG, DHEA-S, fasting insulin, HbA1c and AMH — together they identify which type of PCOS is driving symptoms.

What to do next

  • Identify the PCOS subtype (insulin-driven, adrenal, post-pill, inflammatory)
  • Address insulin first — protein, strength training, sleep, sometimes inositol or metformin
  • Re-test after 3–6 months to confirm the protocol is working

Frequently asked

Can I have PCOS without cysts on ultrasound?

Yes — 'polycystic ovaries' is just one of three diagnostic criteria. Many women with PCOS have completely normal-looking ovaries.

Will the pill fix PCOS?

The pill masks symptoms but doesn't address the underlying insulin or androgen drivers. Many women find symptoms return — sometimes worse — when they come off.

Can PCOS be reversed?

Insulin-driven PCOS responds dramatically to nutrition, training and sleep. Cycles often regularise within a few months — though the genetic susceptibility doesn't disappear.

What blood tests diagnose PCOS?

There's no single test. We look at LH:FSH ratio, total and free testosterone, SHBG, DHEA-S, fasting insulin, HbA1c and AMH — together they identify which PCOS subtype is driving symptoms.

Can lean women have PCOS?

Yes — about 20% of women with PCOS are lean. The driver is usually adrenal androgens or post-pill rather than insulin, and the treatment is different.

Does PCOS cause infertility?

PCOS is the most common cause of anovulatory infertility, but it's also one of the most treatable. Most women with PCOS conceive once ovulation is restored.

Will inositol help?

Myo- and d-chiro-inositol (40:1) improve insulin sensitivity and restore ovulation in many women with insulin-driven PCOS within 3–6 months. It's cheap, evidence-backed and a sensible first step alongside lifestyle work.
