PCOS or Poly-Ovarian Cyst Syndrome, is a condition of the endocrine system in women of reproductive age. Women with PCOS have enlarged ovaries, which are due to cysts filled with fluid, in each ovary, which are located with the help of an ultrasound examination. These cysts cause hormonal imbalances, making it difficult for women to get pregnant, and also cause unwanted changes in the way one looks. If not treated, PCOS can cause serious health problems like diabetes and heart disease, which are long-term effects of this condition.
