why symptoms vary so much
pcos affects everyone differently, and the symptoms someone notices can depend on their age, genetics and stage of life. some people notice changes to their cycle first, others notice changes to their skin or hair, and some don't notice obvious symptoms at all. because of this variation, it helps to know the general range of symptoms associated with pcos, while remembering that having one or two of these on their own doesn't necessarily mean pcos is the cause.
changes to the menstrual cycle
- periods that are irregular, infrequent, or absent
- cycles that are longer than typical
- heavier or lighter bleeding than usual
- difficulty predicting when a period will arrive
irregular ovulation is common in pcos, which is often what lies behind these cycle changes.
skin and hair changes
- acne, particularly along the jawline and chin
- excess hair growth on the face or body (sometimes called hirsutism)
- thinning hair on the scalp
- oilier skin than usual
these changes are often linked to higher levels of androgens, hormones that everyone produces but which can be elevated in pcos.
other changes some people notice
- weight gain, or finding it harder to manage weight
- fatigue or low energy
- mood changes
- difficulty conceiving
not everyone with pcos experiences all, or even most, of these. some people are diagnosed after years of subtle symptoms, while others are prompted to seek advice because of one particular change.
when to speak to a doctor
if you notice a pattern of irregular periods alongside other changes like acne or hair growth, it's worth booking an appointment with your gp. they may ask about your symptoms and cycle history, and could suggest blood tests or an ultrasound scan to help understand what's going on. many conditions can cause similar symptoms, so a proper assessment is the only reliable way to understand what's happening for you.
