What are the failure rates and risks of a surgical abortion?

If you are travelling to the UK for a surgical abortion, you may wonder what the risks are. Although there is a low risk of complications happening during a surgical abortion, it's important that you are aware about them.

Generally, abortions done in the first 12 weeks (first trimester) of pregnancy have the lowest risk. Abortions done after 12 weeks have a higher risk of complications. If you have an abortion in a safe, clinical setting like a Marie Stopes UK centre you're at a low risk of complications. 

Risks and failure rates of surgical abortion

Surgical abortion is a procedure that uses gentle suction to remove the pregnancy tissue from the womb. This procedure is safer when it's done before 12 weeks gestation. Marie Stopes UK Centres can do terminations up to 24 weeks. Surgical abortion can be done under a local anaesthetic, or conscious sedation, and is done under a general anaesthetic at higher gestations.  

Most women experience no complications when having a surgical abortion. However, you might experience minor abdominal pain and some mild vaginal discharge or bleeding after the procedure. This generally settles after a few days. 

The rate of major complications from surgically abortion has declined dramatically and in 2015 is now about 1 in 1000 abortions. 

The following risks are linked with surgical abortion:

Complications relating to the anaesthetic

These are rare, and would be discussed with you by the anaesthetist on the day of your termination.

Injury inside the body

Damage to the uterus (0.86-1.4 in 1,000 cases); damage to the cervix (less than 1 in 100 cases).

Haemorrhage

Blood loss requiring transfusion happens in approximately 0.5-2 cases in 1,000. This risk of haemorrhage increases to 4 in 1000 after 20 weeks.

Infection

Following abortion, infection can happen in up to 10% of women but this is usually not serious. We reduce your risk of infection at Marie Stopes by giving you antibiotics at the time of your termination.

Retained pregnancy tissue

This happens in less than 1% of abortions and usually requires another procedure or some medication to help remove the retained pregnancy tissue. 

Failure of abortion

All abortions carry a small risk of failure, which may require a further procedure. This risk is approximately 2.3 in 1000 for surgical abortion.

Rhesus isoimmunisation

Women with a certain blood group (rhesus negative) are at risk of isoimmunisation after induced abortion. At Marie Stopes, we administer Anti-D to all women who are rhesus negative whether they have a medical or surgical abortion. This helps prevent problems for future pregnancies.

Thrombosis (Clots in the legs or lungs)

This is a risk of being pregnant and a risk of any surgery. The risk increases with a higher gestation. 

Death

There is a very low risk of death with a surgical abortion - 3 in 100,000 cases at 13-15 weeks, and 12 in 100,000 cases after 21 weeks.

While it's important to know about complications, they are rare. If at any time you're concerned about symptoms you're experiencing, please call our 24-hour telephone advice line on 0345 122 1441 for advice and follow-up appointments.

Long term complications

Effects on future reproduction

It's unlikely that having an abortion will have any affect on your fertility - most women go on to have a normal pregnancy. There's some evidence that repeated surgical abortions are linked with a slight increased risk of miscarriage, but there's no evidence this happens with medical abortions.

Breast cancer

There has been no proven link between having an abortion and breast cancer.

Psychological effects

Following an abortion, it's completely normal to experience a range of feelings such as relief, guilt, regret, anxiety and sadness. For most women, these feelings fade after a few weeks or months. Serious emotional problems after an abortion aren't common. For many women, abortion is a way of coping with a personal crisis situation. At Marie Stopes we offer confidential, impartial counselling to all women. Find out more about our counselling services
