Miscarriage and infertility treatment increase pre-eclampsia risk
Date:12/18/2008

pment of the pregnancy. Failure in the development and function of the placenta seems to be an important mechanism in the development of pre-eclampsia but no-one knows why. The results from this study show that the protective effect seen after earlier normal pregnancies (births or terminations) is not present among women with repeated miscarriages. The study indicates that common causal factors linked to the placenta's development and function may be present in infertility, repeated miscarriages and pre-eclampsia.

Facts about pre-eclampsia

  • Affects 3-5 % of all pregnant women.
  • Greatest risk among first-time mothers.
  • Appears in second half of pregnancy
  • Recognised by high blood pressure and protein in mother's urine.
  • In mild cases the mother can be unaffected by the condition, but in serious cases, pre-eclampsia can be life-threatening for mother and baby, with organ failure and danger of seizures among mothers.
  • The child risks poor growth and development due to insufficient placenta function.
  • The only treatment is delivery of baby and placenta.
  • Pre-eclampsia is therefore an important cause of premature birth.
  • Among women who have given birth earlier, the risk is approximately halved. The same applies to women who have had earlier terminations. It is unknown why earlier normal pregnancies protect against pre-eclampsia in later pregnancies.
