Ablation is a procedure that destroys a thin layer of the lining of the uterus to help control heavy bleeding. This procedure may be done in the office or the hospital. The doctor will use one of a number of types of energy to burn away the uterine lining such as electrical, laser (light), thermal (heat), or cryo (cold). Ablation works well for many women to decrease or stop altogether the menstrual flow and may be an option for a woman who does not wish to become pregnant.
