A caesarean section is an operation to deliver a baby. It involves making a cut in the front wall of a woman’s abdomen (tummy) and womb.
The operation can be:
A caesarean section is carried out under regional anaesthetic, where the lower part of your body is numbed. It usually takes 30–45 minutes.

A caesarean section is usually carried out when a normal vaginal birth could put you or your unborn baby at risk, for example because:

Pregnant women are not immediately entitled to a caesarean section if they do not have any physical or mental need for it. If you ask for the operation, you'll be asked why you're requesting it and you'll be given information about the risks and benefits. You should be allowed to have a caesarean if, after discussion and support, you still want to have the operation.
A caesarean section is major surgery and many women opt for a vaginal birth after learning more about what the surgery involves.
In 2011, the National Institute for Health and Clinical Excellence (NICE) published new guidelines on caesarean sections. This aimed to avoid unnecessary operations.
NICE made a few new recommendations:

Like any surgery, a caesarean section carries a certain amount of risk, such as the wound becoming infected or the baby developing breathing difficulties. Read more about the risks of a caesarean section.
It takes longer to recover from a caesarean section than it does from a vaginal birth. You will typically need to spend three to four days in hospital after surgery. Read more about recovering from a caesarean section.
The abdomen is the part of the body between the chest and the hips.
Although it is a common procedure, a caesarean section is still major abdominal surgery. Like any operation, it carries a certain amount of risk.
The main risks to you when having a caesarean section include:
However, a recent change in practice means that infections should become a lot less common. Doctors now give women antibiotics before operating, which reduces the risk of developing an infection more than if antibiotics are given after the operation.
If you have an emergency caesarean section, there is a risk that you will vomit during your operation. If this happens, food and fluid particles can pass from your stomach into your lungs. This is known as aspiration.
This can cause potentially serious inflammation (swelling) of the lungs, known as aspiration pneumonitis.
Eating during labour may increase the amount of food and fluid in your stomach and increase your risk of aspiration if you need to have an emergency caesarean.
If there is a chance that you may need to have a caesarean section, drinking isotonic drinks (that have the same concentrations of salt and sugar as human body fluid) can give you energy during labour without giving you a full stomach.
Having a caesarean section has not been shown to increase or decrease the risk of your baby having the most serious complications, such as an injury to the nerves in the neck and arms, bleeding inside the skull, cerebral palsy or death. These complications are very rare and affect fewer than 20 in 10,000 babies.
The most common problem affecting babies born by caesarean section is breathing difficulties, although this is mainly an issue for babies born prematurely. For babies born at or after 39 weeks by caesarean section, this breathing risk is reduced significantly to a level similar to that associated with vaginal delivery.
Straight after the birth and in the first few days of your baby's life, they may breathe abnormally fast. This is called transient tachypnea. Most newborns with transient tachypnea recover completely within two or three days.
If you think your baby is experiencing breathing difficulties, see your doctor.
Your caesarean section should be performed under a regional anaesthetic. This numbs the lower part of your body but means you will be awake during your operation.
This is safer for you and your baby than a general anaesthetic, when you are put to sleep.
The regional anaesthetic will be given into your spine (called an epidural). You may be offered a pain-relief injection at the same time that will come into effect after your operation.
You will need to have a catheter (tube) inserted into your bladder to empty it. This is because, with a regional anaesthetic, you will not be able to tell if your bladder is full and needs emptying.
Before the procedure, you'll be offered antibiotics to reduce your risk of developing an infection after the operation.
A caesarean section usually takes 30–45 minutes. In an emergency, the operation can be done within 30 minutes.
A screen will usually be placed across your abdomen during the procedure so you do not have to watch the operation being done. However, you can choose to have the screen lowered to see your baby being born.
During the procedure, the operating table will be tilted sideways to an angle of at least 15 degrees. This takes the pressure off your womb and abdomen, reducing your chance of getting low blood pressure and feeling sick during the operation.
A horizontal cut will be made to your lower abdomen at the top of your pubic bone, often described as along your bikini line. This allows another horizontal incision to be made in the wall of your womb to deliver your baby. The low incision will cause you less pain afterwards and looks better than a vertical (up and down) scar.
Sometimes a baby’s skin may be cut when the opening in the womb is made. This happens in 2 out of every 100 babies delivered by caesarean section.
Once your baby has been delivered through the incision made in your womb, the placenta soon separates and is also removed. The wall of your womb and abdomen will be closed with stitches that will later safely dissolve.
You should be given an injection of the hormone oxytocin once your baby is born, to encourage your womb to contract and reduce blood loss.
Your healthcare team will encourage you to have skin-to-skin contact with your baby as soon as possible.
Anaesthetic An Anaesthetic is a drug used to either numb a part of the body (local) or to put a patient to sleep (general) during surgery.
EpiduralAn epidural is an anaesthetic injection given into the epidural space that surrounds the spinal cord, especially during labour, to numb the lower half of the body.
Local anaesthetic A local anaesthetic is a drug that is injected by needle or applied as a cream. It causes a loss of feeling in a specific area of the body.
Spine The spine supports the skeleton and surrounds and protects the delicate spinal cord and nerves. It is made up of 33 bones called the vertebrae.
A caesarean section is usually performed when a normal vaginal birth could put you or your unborn baby at risk.
It can either be planned or carried out as an emergency procedure.
Before you give birth, your midwife or doctor should discuss the benefits and risks of having a caesarean section compared with a vaginal birth.
Medical reasons for having a planned caesarean section include:
In an emergency, there may not be enough time to discuss fully the options of a caesarean section. If vaginal delivery poses significant risks to your own or your baby's health, the midwife or doctor will decide if a caesarean section is the safest option.
Reasons for needing an emergency caesarean include:
In some emergency situations, a baby may need to be delivered very quickly, even within half an hour. In such emergencies, a caesarean section can be the safest way to protect both you and your baby.
Women over 35 years old are more likely to need a caesarean section because they have an increased risk of certain complications during pregnancy, such as:
It takes longer to recover from a caesarean section than it does after a vaginal delivery.
You should be able to get out of bed fairly soon after the operation, and your wound dressing will be removed after 24 hours. Women generally stay in hospital for two to three days after a caesarean section. However, if you and your baby are well and want to go home earlier, you should be able to leave after 24 hours and have your follow-up care at home.
In the first few weeks after giving birth, try to get as much rest as possible. Avoid walking up and down stairs too often as your tummy may be sore. But take gentle walks daily to reduce your risk of blood clotting.
You should be given regular painkillers to take at home for as long as you need them. Your midwife should also give you advice on how to look after your wound to prevent infection, such as wearing loose comfortable clothing and cotton underwear, and gently cleaning and drying the wound daily.
In general, it will take about six weeks for all your tissues to heal completely. Before this time, basic activities, such as caring for your new baby and looking after yourself, should be possible.
However, you may not be able to do some activities straight away, such as driving a car, exercising, carrying heavy things and having sex. Only start to do these things when you feel able to do so. Ask your midwife for advice if you're unsure.
If you drive, check your insurance cover for any restrictions about driving after a caesarean. Some companies require your doctor to certify that you are fit to drive. Most women do not feel fit to drive for a few weeks after a caesarean and many wait until after their six-week postnatal check.
If you have had a delivery by caesarean section, it does not necessarily mean you will have to have a caesarean again in the future. You can discuss future pregnancy options with your doctor, who should take account of:
If the caesarean was carried out for a health reason that will not change in your next pregnancy (for instance, if you have a very narrow birth canal), it is likely that a caesarean section will be necessary for each birth.
If you want to have a vaginal birth, your healthcare team should support your decision. However, make sure you are aware of the serious complications you may be at risk of, including your scar tearing.
During your labour, you should be offered electronic foetal heart rate monitoring to keep a constant check on your baby. You should also be cared for in a maternity unit that has blood transfusion services and the facilities to do a caesarean section very quickly if necessary.
