There is a possibility of minor discomfort during your recovery from endometrial ablation. However, you should not experience notable pelvic pain or continued abnormal bleeding. These symptoms could indicate that scar tissue has developed in the uterus. Scar tissue can distort the structure of the uterus, creating challenges that require further diagnostic testing and treatment. If pain and abnormal bleeding or, conversely, obstruction to menstrual flow, occur due to the formation of scar tissue in the uterine cavity, your doctor may recommend that you undergo a hysterectomy. According to studies, patients treated with endometrial ablation typically receive predictable results that last up to seven years. After that point, the chances of needing a hysterectomy increase.
