Thermal uterine ablation is a minimally invasive in-office procedure performed along with a hysteroscopy that is an alternative to hysterectomy for excessive menstrual bleeding. Your physician will recommend the procedure that is best suited for you. Most women will have reduced menstrual flow following endometrial ablation, and up to half will stop having periods. This procedure is performed either in-office or outpatient at the hospital depending on your insurance.
