Approximately 7% of women give birth to a pre-term baby. A pre-term birth is defined as a baby born at less than 37 weeks gestation. Unfortunately, women who do give birth early have a three times greater risk of another pre-term birth and an even greater risk if they have had two pre-term births.

Many of these pre-term births are not preventable because there are no obvious causes. Other pre-term births can be associated with complications for the mother, or the baby is distressed. Approximately 40% of women who are expecting twins or triplets can expect a pre-term birth.

If you suspect you might be at a higher risk of having a pre-term baby, you should discuss your concerns with your doctor. Your doctor might refer you to a specialist.

An obstetrician specializes in women's health and a perinatologist deals with problem pregnancies.

Your doctor or specialist may suggest a few procedures that will help to determine a possible pre-term birth. These might include an ultrasound of your cervix to determine length; testing for infection and information on the symptoms of pre-term labour. If a pre-term birth is imminent you may be given medication to mature your baby's lungs.
