PCOS (polycystic ovary syndrome)
PCOS is a common hormonal condition affecting periods, ovulation, skin, hair and metabolic health. Australian guidelines are clear that diagnosis needs a careful assessment, not a single scan.

- Acne, oily skin, or coarse hair on face, chest or abdomen
- Hair thinning on the scalp
- Difficulty falling pregnant
- Weight changes, sugar cravings, fatigue
Useful to track
- Period start dates and cycle length
- Skin and hair changes
- Mood and energy
- Sleep and snoring
Tests and conversations that may be relevant
- Blood tests: androgens, LH/FSH, prolactin, thyroid, and often glucose and lipids
- Pelvic ultrasound (not required for diagnosis in people within 8 years of their first period)
- Blood pressure and metabolic screening
When to see a GP or specialist
- Cycles shorter than 21 or longer than 35 days
- No period for 3 months
- Fertility concerns
- Distressing skin or hair changes
Urgent warning signs
- Heavy bleeding with dizziness
