Causes of stillbirth

A 'stillbirth' is the death of a baby after 24 weeks of pregnancy but before birth.

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:

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:

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.

    Hi there. I am so sorry to hear about your son. Your love and emotions for him will have never changed in those 40yrs and that is natural, maternal love. I do wish you well and hope that you have good support. If you have not been offered counselling via your GP, as this is still really affecting you, i would suggest that this might be worthwhile for you. Please take care.

    As my son was stillborn over 40 years ago, it still hurts immensely as he was taken away from me straight away and I was never told what happened to him. Please if yes can help me I would be so very grateful.
