Stillbirth refers to the death of a baby after 24 weeks of pregnancy but before birth. A miscarriage is the loss of a baby before 24 weeks of pregnancy.
The medical profession describes stillbirth as either ‘intra-uterine’ or ‘intra-partum’. An intra-uterine stillbirth means that the baby has died in the womb. An intra-partum stillbirth means that the baby dies during labour.
What are the causes of stillbirth?
The most common reason for stillbirth is failure of the placenta, also referred to as placenta insufficiency. This is why Tommy's stillbirth research centre in Manchester focuses on the functioning of the placenta, and has a placenta clinic for women at high risk of placental problems.
The placenta delivers nutrients and oxygen to the baby. These are crucial to the baby's growth and development. If the placenta has problems, the baby does not receive enough nutrients and oxygen and fails to grow or develop. This is called intrauterine growth restriction (IUGR) or fetal growth restriction (FGR).
One of the first signs that a baby may not be getting enough food or oxygen is reduced movements and this is why health professionals ask that women monitor the pattern of their baby's movements from 16-22 weeks onwards and get in touch with the hospital immediately if they notice a change in the pattern.
Intrauterine infection is another less common cause of stillbirth. It is responsible for 1 in 10 stillbirths.
Other risk factors for stillbirth are:
- obesity during pregnancy - when the mother's BMI is over 30
- smoking during pregnancy - cigarette smoke sends toxins down the placenta to the baby instead of oxygen.
- the mother's age during pregnancy - there is an increased risk after 35, and again after 39.
What are the symptoms of stillbirth?
Some women say they simply knew that the baby was no longer alive, and then went to hospital where a scan would have confirmed this.
Others aren’t aware until a routine appointment finds no heartbeat, or a scan reveals the baby has died.
How can I avoid stillbirth?
There are some factors that will be beyond your control, such as your age, but there are some things you can do to reduce your risk, such as:
- quitting smoking if you smoke - cigarette smoke prevents oxygen from reaching your baby
- avoiding alcohol and drugs during pregnancy – these can seriously affect your baby's development and increase the risk of miscarriage and stillbirth
- going to all your antenatal appointments and scans so that midwives can check that your baby is growing as it should
- get to know the pattern of your baby's movements from 16-22 weeks and report any reduction immediately to your hospital.
Giving birth to a stillborn baby
If the baby is found to be stillborn before labour has started it can be an intensely difficult time to decide and think about giving birth.
Sometimes the baby may need to be born straight away for the mother's health, but sometimes this is not the case. If it is not the case the parents wait be able to wait for labour to start naturally.
Giving birth naturally is usually safer than a caesarean section and medication will be given to induce the woman's labour, it can take up to 48 hours to work.

Making the decision to try again for another baby after a stillbirth is a very personal one
The loss of a baby at any time is one of the most devastating and personally unique experiences any individual can go through.
Some women say they simply knew something was wrong and went to hospital. Others weren’t aware until a routine appointment finds no heartbeat, or a scan reveals the baby has died.
For many people, the loss of a baby leaves them feeling shocked, isolated and empty.
After losing your baby you will have to cope with immense grief and a mixture of emotions, as well as the physical aspects of losing a baby.
After a stillbirth you will have to deal with the emotions of losing your child.
After giving birth to a baby who has died you will have decisions to make, but take things at your own pace and discuss what you would like.
Many women who suffer a stillbirth don't notice any changes and there is nothing that can be done to save their baby. However, there are some things that you should look for during your pregnancy.
