Do PFAS and prediabetes together double your heart attack risk?
Yes, the two stack. PFAS in someone with prediabetes pushes the same arteries that are already strained, with measurable extra heart attacks and strokes.
What's actually in it
People with prediabetes already have stressed blood vessels. Higher blood sugar damages the inner artery wall over time. PFAS in the blood add to that damage. They drive inflammation, raise cholesterol, and mess with how blood vessels relax. The two stressors stack.
What the research says
A 2026 study in J Am Heart Assoc followed adults with prediabetes and tracked their PFAS and heart events. Higher PFAS lined up with more heart attacks, strokes, and other cardiovascular events. The stack was bigger than what either factor showed alone. A 2026 review in Ecotoxicol Environ Saf mapped the steps from PFAS to artery damage.
If you have prediabetes, PFAS swaps pay off fast. Toss nonstick cookware for cast iron or stainless. Filter tap water with reverse osmosis. Skip greaseproof takeout liners. Pick plain cotton clothes over stain-resistant treated fabrics. These swaps cost little.
