What is an endometrial resection?
An endometrial resection is an operation to remove the lining (endometrium) of your uterus (womb).
What are the benefits of surgery?
The most common reason for having an endometrial resection is to relieve the symptoms of heavy periods (abnormal uterine bleeding).
About a third of women who have the operation will not have periods anymore.
Are there any alternatives to surgery?
Heavy periods can be treated using a variety of non-hormonal and hormonal oral (by mouth) medications.
Other alternatives include an IUS (intrauterine system) — an implant containing a synthetic form of the hormone progesterone that fits in your womb — but these are usually tried before surgery is recommended.
What does the operation involve?
The operation is usually performed under a general anaesthetic but various anaesthetic techniques are possible.
The operation usually takes about 30 minutes.
Your gynaecologist will examine your vagina. They will pass a small telescope (operating hysteroscope or resectoscope) through your vagina, across your cervix (neck of your womb) into your womb.
Your gynaecologist will pass fluid through the telescope to distend (swell) your womb. They will use a diathermy resecting loop (a loop of wire heated by electricity) to remove the lining of your womb and any polyps or small fibroids they find.
How can I prepare myself for the operation?
If you smoke, stopping smoking now may reduce your risk of developing complications and will improve your long-term health.
Try to maintain a healthy weight. You have a higher risk of developing complications if you are overweight.
Regular exercise should help to prepare you for the operation, help you to recover and improve your long-term health. Before you start exercising, ask the healthcare team or your GP for advice.
Speak to the healthcare team about any vaccinations you might need to reduce your risk of serious illness while you recover. When you come into hospital, practise hand washing and wear a face covering when asked.
What complications can happen?
Some complications can be serious and can even cause death.

Consequences of this procedure
How soon will I recover?
You should be able to go home the same day.
You should be able to return to normal activities after 2 to 4 days. Most women are fit for work after about a week.
You should expect to have some bleeding or discharge for up to 4 weeks.
Regular exercise should help you to return to normal activities as soon as possible. Before you start exercising, ask the healthcare team or your GP for advice.
The operation is not recommended for women who still want children.
Even if your periods stop, there is still a risk of becoming pregnant.
