Polycystic ovary syndrome (PCOS) is a hormone disorder that affects teenage girls and women. It is the most common endocrine disorder in women.
Polycystic means "many cysts.” A main feature of PCOS is that eggs are not released from the ovaries. Instead, fluid builds up around the eggs, forming sacs (cysts). Though this feature is the origin of the name of the disorder, not all women diagnosed with PCOS have polycystic ovaries.
The underlying causes of PCOS are not well understood, but it is believed that an imbalance of sex hormones and resistance to the effects of the hormone insulin are the main problems. These problems can result in a defined group of signs, symptoms and complications, such as excess facial and body hair, weight gain, irregular menstrual periods, infertility, and increased risk of diabetes and heart disease.
A fasting 9.00am sample is recommended.
