PFAS Exposure During Pregnancy Raises Preeclampsia Risk

Preeclampsia is one of the most dangerous pregnancy complications. It can cause seizures, organ failure, and death. A new study says PFAS chemicals may be raising the risk.
The ECHO Cohort Findings
A 2026 study in Environ Res used data from the ECHO Cohort Consortium, a large multi-site U.S. study following pregnant women and their children. Researchers measured PFAS levels in pregnant women and tracked who developed preeclampsia.
The study found associations between gestational PFAS exposure biomarkers and the risk of developing preeclampsia. PFAS are found in nonstick cookware, stain-resistant fabrics, water-resistant clothing, food packaging, and contaminated drinking water.
Why PFAS and Preeclampsia Are Connected
Preeclampsia involves abnormal blood vessel development in the placenta, inflammation, and disrupted blood pressure regulation. PFAS are known endocrine disruptors that interfere with hormonal signaling and promote inflammation, exactly the kind of disruption that could tip the scales toward preeclampsia.
These are "forever chemicals." They don't break down, and they accumulate in the body over time. By the time a woman becomes pregnant, she may have decades of PFAS buildup.
What You Can Do
Start reducing PFAS exposure before pregnancy if possible. Replace nonstick cookware with stainless steel or cast iron. Use a water filter rated for PFAS removal. Avoid food wrappers and containers with grease-resistant coatings. Browse our non-toxic baby products for safer options during and after pregnancy.
