Endometrial ablation is a surgery or procedure done to disrupt the lining of the uterus in order to minimize heavy or prolonged menstrual flow. This lining is called the endometrium. The surgery may be done in a hospital, outpatient surgery center, or the provider's office.


Endometrial ablation is a procedure used to treat abnormal bleeding by destroying tissue in the uterine lining. The tissue can be removed using:

Some types of procedures are done using a thin, lighted tube called a hysteroscope that sends images of the inside of the womb to a video monitor. Most of the time general anesthesia is used so you will be asleep and pain free.

However, newer techniques can be done without using a hysteroscope. For these, a shot of numbing medicine is injected into the nerves around the cervix to block pain.

Why the Procedure Is Performed

This procedure can treat heavy or irregular periods. Your health care provider will likely have tried other treatments first, such as hormone medicines or an IUD.

Endometrial ablation will not be used if you may want to become pregnant in the future. Though this procedure does not prevent you from getting pregnant, it may reduce your chances of getting pregnant. Reliable contraception is important in all women who get the procedure.

If a woman gets pregnant after an ablation procedure, the pregnancy will often miscarry or be extremely high risk because of the scar tissue in the uterus.


Risks of hysteroscopy include:

Risks of ablation procedures vary depending on the method used. Risks may include:

Risks of any pelvic surgery include:

Risks of anesthesia include:

Risks of any surgery include:

Before the Procedure

A biopsy of the endometrium or lining of the uterus will be performed in the weeks prior to the procedure. Younger women may be treated with a hormone that blocks estrogen from being made by the body for 1 to 3 months before the procedure.

Your provider may prescribe medicine to open your cervix. This makes it easier to insert the scope. You need to take this medicine about 8 to 12 hours before your procedure.

Before any surgery:

In the 2 weeks before your procedure:

On the day of the procedure:

After the Procedure

You may go home the same day. Rarely, you may need to stay overnight.

Your provider will tell you the results of your procedure.

Outlook (Prognosis)

The lining of your uterus heals by scarring. Women will most often have less menstrual bleeding after this procedure. Up to 30% to 50% of women will completely stop having periods. This result is more likely in older women. Women who continue to have heavy bleeding may need additional surgery.
