The endometrium is the lining of your uterus (womb). Endometrial ablation is the surgical removal or destruction of this lining. There are different methods of destroying the endometrium including electricity, laser therapy or freezing.
A specialist performs the operation and it is done through the vagina, so there is no need for the abdomen to be cut open. The endometrium will heal leaving scarring, which usually reduces or stops menstrual periods.
In women who have very heavy periods (menorrhagia), an endometrial ablation can be done instead of a hysterectomy as it is an easier procedure than a hysterectomy and is quicker to recover from. Endometrial ablation is only performed in women who no longer wish to have children.
