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.

Statistics about pre-eclampsia

Pre-eclampsia usually happens in the second half of pregnancy (from around 20 weeks) or soon after a baby is delivered. Early signs include high blood pressure and having protein in the urine. Further symptoms may include swelling of the feet, ankles, face and hands, severe headache, vision problems and pain just below the ribs. As delivering the baby is the only ‘cure’ for pre-eclampsia, it is a cause of preterm birth.

1 in 10 pregnancies in the UK are complicated by pre-eclampsia.

  • Around 5 in 1,000 pregnancies are complicated by severe pre-eclampsia.
  • 15–20% of all preterm births are attributable to pre-eclampsia.
  • A woman who has had pre-eclampsia has a 16% risk of having it again in a future pregnancy.
