Can PFAS exposure during pregnancy raise your blood pressure?
Possibly. A 2025 longitudinal study found that high PFAS exposure during pregnancy was linked to altered blood pressure trajectories.
What's actually in it
PFAS enter a pregnant woman's body through nonstick cookware, food packaging, contaminated water, and stain-resistant fabrics. These chemicals persist in blood for years. During pregnancy, blood volume increases and PFAS circulate more actively, potentially affecting vascular function and blood pressure regulation.
What the research says
A 2025 longitudinal study in Environ Res from the Ronneby Mother-Child Cohort tracked blood pressure throughout pregnancy in women with high PFAS exposure from contaminated drinking water. The researchers compared their blood pressure trajectories to women with lower PFAS levels.
Women with higher PFAS exposure showed different blood pressure patterns during pregnancy. The changes were consistent with the kind of vascular dysfunction that can lead to preeclampsia and other pregnancy complications.
Filter your drinking water with a system rated for PFAS removal. Avoid nonstick cookware and PFAS-treated products during pregnancy. These steps help even if you start them mid-pregnancy.
