Polycystic ovary syndrome (PCOS) is a common endocrine system disorder in women where the ovaries become enlarged and retain fluid. PCOS symptoms include irregular or missed periods, excessive body hair, high levels of the hormone insulin, and weight gain. Exact causes are unknown, but excess insulin, general inflammation and heredity (in the family) are thought to play a role.
