The lining of the uterus, the endometrium, is shed by bleeding each month during menstruation. Some women have heavy bleeding or bleeding that lasts longer than normal. For them, endometrial ablation may be a good treatment option. This procedure treats and destroys the lining of the uterus to control or stop bleeding. Pregnancy is not likely after ablation, but it can happen. If it does, the risk of miscarriage and other problems are greatly increased. If a woman still wants to become pregnant, she should not have this procedure. Women who have endometrial ablation should use birth control until after menopause. Sterilization may be a good option to prevent pregnancy after ablation. There are different methods to perform endometrial ablation, including radiofrequency, freezing, heated fluid, heated balloon, microwave, and electrosurgery. Endometrial ablation works well for many women who have heavy bleeding. Endometrial ablation may be an option for a woman who does not wish to become pregnant. If you are thinking about having an endometrial ablation procedure, talk to your healthcare provider about the risks and benefits.
