Can PFAS from cookware harm liver function during pregnancy?
Yes. Gestational PFAS exposure is linked to elevated liver enzymes and impaired liver function in pregnant women.
What's actually in it
Pregnancy puts extra demands on the liver. The liver processes hormones, filters the blood, and supports the growing metabolic needs of both mother and baby. Adding PFAS to the liver's workload during this already-demanding period creates additional stress.
PFAS from nonstick cookware, food packaging, and stain-resistant products accumulate in the liver. They activate liver stress pathways and compete with the normal hormonal regulation of liver function that changes during pregnancy.
What the research says
A 2026 study in Environ Int measured gestational exposure to individual and mixed PFAS and maternal liver function markers. PFAS exposure during pregnancy was associated with elevated ALT (alanine aminotransferase) levels and other liver function disruptions in pregnant women. PFAS mixtures had stronger effects than individual PFAS, consistent with combined exposure from multiple sources.
During pregnancy, the fetus is also exposed to whatever PFAS the mother carries. Liver damage in the mother during pregnancy represents concurrent fetal exposure too.
Switching to stainless steel cookware before and during pregnancy eliminates the cookware route for ongoing PFAS exposure.
