Polycystic Ovary Syndrome (PCOS)

Overview

Your Mayo Clinic doctor may tell you that your irregular menstrual periods, excess hair growth and obesity are a sign of polycystic ovary syndrome (PCOS). This disorder is common in women in their childbearing years. PCOS happens when your pituitary gland and ovaries overproduce certain hormones. Because those hormones can interfere with the production and release of eggs, PCOS is a common cause of infertility and may be the reason you have difficulty becoming pregnant.

If your adolescent daughter has irregular or heavy periods, that can be a sign of PCOS. Early diagnosis and treatment can help reduce her risk of long-term complications such as diabetes and heart disease.
