Pre-eclampsia
Pre-eclampsia is a condition that affects some pregnant women, usually during the second half of pregnancy (from around 20 weeks) or soon after their baby is delivered.
Pre-eclampsia rarely happens before the 20th week of pregnancy. Most cases occur after 24-26 weeks and usually towards the end of pregnancy.
Pre-eclampsia is thought to be caused by the placenta not developing properly due to a problem with the blood vessels supplying it. The exact cause isn't fully understood.
Pre-eclampsia is easily diagnosed during the routine checks you have while you're pregnant.
Pre-eclampsia can only be cured by delivering the baby. If you have pre-eclampsia, you'll be closely monitored until it's possible to deliver the baby.
Although they're rare, a number of complications can develop if pre-eclampsia isn't diagnosed and monitored.
