Hysteroscopy is most commonly performed to diagnose and treat abnormal uterine bleeding or abnormally heavy periods. These disorders can be caused by not only hormonal imbalance, but also benign growths such as fibroid tumors or polyps. Other types of conditions that can be diagnosed or treated with hysteroscopy include infertility caused by blockages or adhesions near the openings of the fallopian tubes as well as other disorders; abnormally painful periods; post menopausal bleeding; irregular or unusually light periods; uterine anomalies, including septum; recurrent miscarriages; pelvic pain and removal of intrauterine devices (IUDs).
