Polyfluoroalkyl substances (PFAS) are a large group of human-made chemicals used since the 1940s in various industrial and consumer products due to their resistance to water, oil, and heat. They are often called “forever chemicals” because they do not break down easily in the environment or the human body. These “forever chemicals” are harmful during pregnancy due to their persistence in the body and their ability to cross the placenta.

Where PFAS are found?

• Non-stick cookware (like Teflon)
• Stain-resistant fabrics and carpets.
• Water-repellent clothing
• Food packaging (especially greasy fast-food wrappers)
• Firefighting foams
• Some cosmetics and personal care products

Effects of PFAS on pregnancy

PFAS can cross the placenta and accumulate in the fetus. Numerous studies suggest potential risks, although the extent of harm may depend on the type and level of exposure.

Health risks linked to PFAS exposure during pregnancy:

1. Lower birth weight: One of the most consistent findings. Babies exposed to utero may be slightly smaller.
2. Preterm birth: Increased risk of delivering before 37 weeks.
3. Pregnancy-induced hypertension and preeclampsia: PFAS may affect blood pressure outcomes regulation.
4. Disruption of thyroid hormones: These hormones are essential for fetal brain and body development.
5. Immune system impacts: Potentially lowering the baby’s immune response.
6. Changes in lipid metabolism and glucose regulation: Which may influence long-term child health.
7. Long-term child health effects: Exposure may be associated with later risks of obesity, hormonal issues and learning or behavioral disorders.

How to reduce PFAS exposure during pregnancy

1. Avoid non-stick cookware with PFAS (opt for ceramic or cast iron).
2. Minimize fast food and microwave popcorn (often in PFAS-lined packaging).
3. Check beauty and skincare products for PFAS (look for ingredients like PTFE or “fluoro”).
4. Use water filters certified to remove PFAS (especially if you live near known contaminated areas).
5. Stay informed about local water quality and avoid fish from PFAS-contaminated waters.
6. Read labels for ingredients – whether it is food package or cosmetics.

Remember – Your baby’s health depends on your health. What you put in your body directly or indirectly influence baby’s health!
