Can PFAS exposure during pregnancy raise liver concerns?

What's actually in it

PFAS are per- and polyfluoroalkyl substances. They can be used in stain-resistant fabric, water-repellent textiles, some food packaging, and some nonstick coatings.

During pregnancy, the liver is already doing extra work. That is why repeated PFAS exposure deserves careful attention, especially from sources that can be reduced at home.

What the research says

A 2026 study in Environ Int measured 23 PFAS and 11 liver function markers in 601 pregnant women from the Wuxi Birth Cohort.

The study found that PFOA, PFNA, PFDA, and PFUdA were linked with higher ALT and other liver markers. PFAS mixture models were also linked with liver markers. In pregnant rats, PFNA and PFDA exposure changed liver function markers and liver metabolic pathways.

This does not prove that one stain-resistant couch or jacket harms pregnancy. It does support lowering repeat PFAS contact. Choose untreated cotton, linen, silk, bamboo, or wool textiles when practical. Skip stain-resistant sprays, and avoid heating food in coated packaging.
