PCOS can also affect fertility and pregnancy complications.
Oscar-winning actress Emma Thompson has spoken of her difficulty in conceiving a child due to reportedly suffering from PCOS. She and her then-husband Kenneth Branagh conceived their daughter Gaia through IVF (Thompson, who is now married to actor Greg Wise, also adopted a Rwandan orphan in 2003).
Celebrities Victoria Beckham and Jillian Michaels have also suffered fertility problems related to PCOS.
The pregnancy complications that PCOS pose include risk of miscarriage, gestational diabetes and higher risk of premature birth.
Though it is not known what causes PCOS, a doctor can diagnose the disorder through a blood test (to detect high androgen levels) and an ultrasound to examine ovaries.
For those suffering from the syndrome, doctors recommend healthy lifestyle changes and weight loss. Exercise and a good diet have proven to improve PCOS symptoms.
As for medicine, there is no magic pill to cure symptoms but birth control pills can regulate periods and treat other hormonal symptoms such as hair growth and acne.
Metformin (a drug that treats diabetes) can regulate the menstrual cycle.
