Pregnancy accelerates biological aging but much of the effect is reversed after delivery, especially in people who breastfeed. Research shows that being pregnant is associated with faster molecular aging, which can be reversed to some extent postpartum. Higher BMI is linked to higher biological age, while breastfeeding accelerates the rate of recovery. Future studies will compare aging during pregnancy with pre-pregnancy molecular age to determine if postpartum recovery completely reverses pregnancy-related aging. Researchers aim to identify pregnancy-specific biomarkers for a more precise measure of molecular aging and potentially develop interventions to benefit pregnant individuals.
