New Study Uncovers Lasting Effects of Pregnancy on the Body

Speedy Summary

• New research provides the most detailed insights into how pregnancy affects the blood,organs,and immune system weekly.
• Study analyzed blood samples from over 160,000 women in Israel, covering more than 300,000 pregnancies. changes were tracked from 20 weeks pre-conception to 18 months post-delivery.
• Researchers documented changes in 76 blood markers related to liver, kidneys, muscles, bones, and immune functions during pregnancy. Recovery timelines varied widely for these markers:

– 36 markers recovered within a month post-delivery.
– 31 markers required over ten weeks; some needed up to six months or longer (e.g., kidney and bone-related changes).
– certain markers never returned to pre-pregnancy baselines after a year (e.g., low iron levels linked with anemia).

• Elevated protein CRP levels persisted well after delivery due to inflammation or hormonal shifts.
• Analysis identified that women who developed pre-eclampsia already had elevated levels of specific proteins (e.g., ALT) and platelets before conception. These findings support theories linking cardiovascular function prior to pregnancy with risks of this condition.
