This procedure is a treatment for heavy menstrual periods. There are several methods available; all intend to remove permanently the lining of the womb. Approximately 40% of women who undergo this procedure will have minimal or no bleeding thereafter and another 50% will have lighter periods. Roughly 10% of women will either require a repeat procedure or even a hysterectomy. The procedure is generally performed under a general anaesthetic as a day-case, but it can be done under local anaesthetic in selected cases. Complications are rare, but consist of the risks of infection, bleeding or rarely perforation of the uterus.
