When complications occur
Preterm birth
What is a preterm (premature) birth?
A preterm birth is one that happens before 37 weeks of pregnancy. In about half of all preterm births, the cause is unknown.
Factors that increase the likelihood of a premature birth can be:
- a previous premature birth
- some conditions of the uterus or cervix, such as fibroids or a weakened cervix
- a multiple pregnancy
- a maternal infection
- some maternal medical conditions such as pre-eclampsia.
If babies are premature, they are likely to need extra care at birth.
