Despite its name, polycystic ovary syndrome involves more than cysts. The most common hormonal disorder among women also causes infertility due to a lack of ovulation; increased hair growth on the face, chest, stomach, back, thumbs or toes; acne or oily skin; dandruff; weight gain; pre-diabetes; anxiety or depression; pelvic pain; sleep apnea; skin tags; and thinning hair. Womenshealth.gov estimates that at least 1 in every 20 women of childbearing age has the syndrome. Experts suggest following these steps to better manage PCOS.
