Pre-eclampsia research

Pre-eclampsia is a pregnancy condition that can lead to serious complications for mother and baby if left untreated. Tommy’s think that prevention is better than cure – so we’re supporting research to figure out why it happens and how we can stop it.

Pre-eclampsia is a condition that only affects women during pregnancy, usually in the second half (from around 20 weeks. Worldwide, it is a leading cause of death in both mothers and babies. In the UK, 4-5% of pregnancies are complicated by pre-eclampsia – around 1 in 20 women. Severe cases develop in 1-2% of pregnancies.  Early signs include high blood pressure and protein appearing in urine tests.

The causes of pre-eclampsia aren’t fully understood – we think it is related to the placenta not attaching properly to the wall of the womb.

We need research to find out why it happens, so we can work to prevent it. That’s why Tommy’s supports pioneering research into the causes of pre-eclampsia, and the best ways of finding and caring for women at risk.
