What Causes Polycystic Ovary Syndrome (PCOS)?
Doctors are not sure what causes PCOS. They believe the following might play a role:
- Weight gain or obesity
- Higher levels of insulin in the body than usual and insulin resistance. Insulin is a hormone that helps the body use sugar available in food for energy. When someone has insulin resistance, the body does not use insulin properly.
- Higher levels of androgens (male hormones) in the body than usual
