PCOS in Teens

Polycystic Ovary Syndrome (PCOS) is one of the most common hormone-related conditions in women of reproductive age. In the UK, it is estimated to affect around 1 in 10 women.

While symptoms can start in the teenage years, diagnosing PCOS in adolescents is slightly different from in adults. Current guidelines recommend that for those under 20, doctors look mainly at hormone levels and irregular or absent periods. Ultrasound is not usually advised at this stage, as it has not been found to be reliable in younger women.

Guidelines also note that adolescents who have some features of PCOS, but do not meet the full criteria, may be considered at increased risk. Reassessment is recommended at or before full reproductive maturity (around eight years after starting their first period). This can include girls who had features of PCOS before starting the contraceptive pill, those with persisting symptoms, or those who have gained significant weight during adolescence.

Why early support matters

PCOS is often described as a long-term condition, and its symptoms — such as acne, excess hair growth, hair thinning, or weight changes — can be particularly difficult to cope with during the teenage years.

Although only a GP can make a diagnosis, starting conversations early about nutrition and lifestyle choices may help support overall health and wellbeing in teenagers showing features of PCOS. Parental and family support can also make a big difference in helping young people build positive long-term habits.

The mental health impact

Living with PCOS can sometimes affect mental wellbeing. Research suggests that anxiety, low mood, and depression may be more common in women with PCOS. For teenagers, who are already navigating a time of big changes and pressures, this additional emotional impact may be especially challenging. Supporting both physical and emotional health is therefore important.
