Can PFAS exposure affect your gestational weight gain during pregnancy?
Based on 1 peer-reviewed studybaby
Verdict: Some Concern
Possibly. A 2025 study found that PFAS serum concentrations during pregnancy were linked to altered gestational weight gain patterns.
What's actually in it
PFAS from nonstick cookware, food packaging, and contaminated water accumulate in blood over years. During pregnancy, these stored PFAS can interfere with the metabolic changes needed for healthy weight gain.
What the research says
A 2025 study in Int J Hyg Environ Health from the Healthy Start Study measured PFAS serum levels and tracked gestational weight gain. Women with higher PFAS levels showed altered weight gain trajectories during pregnancy.
Reduce PFAS exposure before pregnancy by filtering water and avoiding nonstick products.
