Pre-eclampsia, also known as pre-eclamptic toxaemia (or PET), is an illness exclusive to pregnancy.

It can affect both mother and unborn baby, and occurs at any time from around 20 weeks of pregnancy until a few days after delivery. It's caused by a defect in the placenta, the source of an unborn baby's oxygen and nutrients.

If undetected and allowed to develop, it could be life-threatening to mum and baby, hence the importance of checkups. It affects one in 10 pregnancies in some form, but affects one in 100 first pregnancies severely.

Can I tell if I'll get it?

Pre-eclampsia can't be predicted, but some women are more at risk. They are:
  • First-time mothers
  • Very overweight women
  • Women over 40
  • Women with a family history of pre-eclampsia
  • Mothers who've left a gap of 10 years or more between babies
  • Women with high blood pressure, diabetes or kidney disease
  • Women with multiple pregnancies
  • Women who've suffered from pre-eclampsia before
