The vast majority of patients who undergo endometrial ablation—up to 90%—are highly satisfied with the results. By satisfied we mean that the patient sees a significant decrease in excessive menstrual flow or PMS symptoms as a result of EA.
In general, about 50% of patients will have no menstrual periods after the procedure, or just have a mild spotting, while another 30-35% notice a great reduction in the menstrual flood to normal or lighter levels.
Global endometrial ablation methods prevent 75% of hysterectomies, with another 25% ends up with hysterectomy. On the NHS, the failure rate for endometrial ablation is about 25-35% and, in case of failure, you may be offered a repeat treatment.
