Polycystic ovary syndrome needs to lose weight, and losing weight itself is a treatment for polycystic ovary syndrome. Polycystic ovary syndrome (PCOS) is that there are many follicles in the ovary, but there are no dominant follicles, which can not ovulate normally and regularly, thus leading to infertility. However, polycystic ovary syndrome is often directly related to obesity. After losing weight, patients can often relieve symptoms and get pregnant normally.
