It is difficult to know exactly how many women have PCOS as many women don’t discuss the symptoms with their doctor until they are having trouble conceiving or are worried about sudden weight gain. It is estimated that up to 10% of women in the UK may have PCOS - with over 50% not experiencing any significant symptoms. Internationally, the overall figure is slightly lower, the World Health Organisation suggests that around 3.4% of women globally have PCOS.
PCOS is very common and you should not delay in speaking to a doctor specialising in women’s health if you have any concerns.
