A hysteroscopy is a procedure used to examine the inside of the uterus (womb).

It's carried out using a hysteroscope, which is a narrow tube with a telescope at the end. Images are sent to a computer in order to get a close-up of the womb.

Why it is used

A hysteroscopy can be used to diagnose cases when a woman’s symptoms suggest there could be a problem with their womb. Symptoms can include:

A hysteroscopy can also be used to remove abnormal growths from the womb, such as:

  • fibroids – non-cancerous growths that can develop inside the womb and can sometimes cause symptoms such as pain and heavy periods
  • polyps – small growths that develop on the lining of the womb and can cause irregular and heavy periods
  • intrauterine adhesions – sections of scar tissue that can cause absent periods and infertility
  • thickening of the uterus' lining (endometrial hyperplasia) – this can increase the risk of womb cancer

A procedure called dilatation and curettage (D&C) used to be commonly used to examine the womb and remove abnormal growths, but nowadays hysteroscopies are carried out instead.

What happens during a hysteroscopy

A hysteroscopy is a common procedure that is often carried out on an outpatient basis. This means you do not have to stay in hospital overnight.

It can be performed under local anaesthetic (when medication is used to numb a small area) or general anaesthetic (when you are asleep during the procedure), depending on the reason for your hysteroscopy.

The surgeon will use a device called a speculum to open up the walls of the vagina, in the same way it is used during a cervical smear test. The surgeon will then insert the hysteroscope through the cervix, into the womb.

Gas or fluid is often used to inflate the womb, to give the surgeon a better view.

If a biopsy or treatment is needed, such as the removal of polyps, other instruments will be passed into the womb.

A hysteroscopy usually takes between 10 and 30 minutes, depending on what needs to be done.

Recovering from a hysteroscopy

Some women will experience cramping similar to period pains after a hysteroscopy, but this usually passes after a few days.

Most women feel they can return to normal activities, such as work, the day after the procedure.

A hysteroscopy is a very safe procedure, with a low risk of complications.

The two most commonly reported complications of a hysteroscopy are:

  • accidental damage to the womb or cervix, which may require further treatment to correct – this occurs in around 1 in 135 cases
  • excessive bleeding during or after surgery, which happens in around 1 in 400 cases

In almost all cases, the benefits of having a hysteroscopy far outweigh the potential risks.

I had a hysteroscopy an hour ago at Liverpool Women's in Aintree Hospital.
The staff were fantastic. 3 nurses in the room, they explained everything. Lovely and friendly. I was very nervous but they put me at ease.
They offered me gas and air, I said no but I wish I had accepted it. The procedure didn't require pain relief as it's over quickly.
The procedure is uncomfortable and you feel like you need the toilet the whole time. If you require a biopsy this is painful but it lasts no more than 5minutes. Afterwards you have period like pain but this has gone for me now-hour later.
So in summary:
Pain isn't too bad take the pain killers before you go.
Accept gas and air.
Expect to feel the need to go the toilet.
Expect pain for 5 mins if you get a biopsy.
