Pre-eclampsia doesn't just affect your blood pressure-if it's severe it can lead to stroke, kidney failure and liver problems. It's known as pre-eclampsia because if left untreated it can result in eclampsia. This is when you have a seizure(fit).Eclampsia can happen at any time during the second half of pregnancy, during labour or after delivery. Almost half of the women who develop eclampsia develop it after the baby is born, usually within 24hrs of delivery. Eclampsia only affects around 2 in 100 women with pre-eclampsia, because pre-eclampsia can be treated once it's been diagnosed.
