What: Researchers took blood samples from more than 160,000 women to examine (for the first time at that population level) how pregnancy impacts organs like the liver, kidneys, and more. They found that changes continued even 18 months post-delivery. 

Key Line: ‘Notably, the scientists found that while 36 of the markers, including those related to blood clotting, bounced back within a month after delivery, 31 markers took more than 10 weeks to recover. For instance, some changes to the liver and immune system took around 5 months to return to pre-pregnancy levels, and several kidney markers took roughly half a year. Some bone and muscle markers took even longer.’
