Endometrial ablation is a procedure that removes the uterine lining with heat, cold, or other sources of energy. If you have heavy periods, your doctor may suggest endometrial ablation as a treatment option. It's less risky than a hysterectomy and has fewer restrictions. Many patients take drugs to reduce their bleeding before having an endometrial ablation. You may have no bleeding, reduced bleeding, or no change in your period after an endometrial ablation.
