Previous Abortions And Exercise: Do They Affect Pregnancy?

Women who have had two or more induced abortions have a reduced risk of pre-eclampsia by 60 %.

It is not currently understood to what degree physical activity during pregnancy protects against pre-eclampsia, compared to previous studies.

Reduced risk for pre-eclampsia among women who have aborted

One study shows that women who have had two or more induced abortions reduced their risk for pre-eclampsia by 60 percent.

That is, they are as well protected against pre-eclampsia as women who have previously given birth to a child.

Women who have had one termination previously, have an approximately 16 % reduced risk for pre-eclampsia compared with women who have never had an abortion. There was no protective effect linked to having had a miscarriage [signs of miscarriage] previously.

Information from 20,846 women was studied. All the women were first-time mothers, and some had previously had miscarriages or abortions.

The results indicate that every normal pregnancy, even if it ends before birth, to some degree will protect against pre-eclampsia in a later pregnancy, almost like a vaccination.

The mechanisms for this effect are currently unknown, and more research is necessary. Miscarriages do not appear to protect against pre-eclampsia.
