Polycystic Ovarian Disease
Polycystic ovary syndrome (say 'pah-lee-SIS-tik OH-vuh-ree SIN-drohm') is a problem in which a woman's hormones are out of balance. It can cause problems with your periods and make it difficult to get pregnant. PCOS also may cause unwanted changes in the way you look. If it isn't treated, over time it can lead to serious health problems, such as diabetes and heart disease.
