Polycystic Ovarian Syndrome (PCOS)
Approximately 1 in 5 women have polycystic ovaries. This is where the ovary is larger than usual and has at least 10 uniform small cysts around the edge (viewed on ultrasound). PCOS is a condition where the balance of hormones is affected causing problems such as greasy skin, acne, problematic hair growth in abnormal places (especially the face), hair loss on the scalp, irregular periods, problems with weight and problems in pregnancy. There may be longer term health concerns.
PCOS can be diagnosed on the basis of the symptoms together with a transvaginal scan or by blood test.
