Research reveals specific thyroid impacts from PFAS exposure
Scientific evidence demonstrates that PFAS exposure affects thyroid function through multiple pathways, causing both underactive and overactive thyroid conditions. PFAS chemicals like PFOS, PFOA, and PFHxS disrupt thyroid-stimulating hormone (TSH) levels, which can trigger hypothyroidism when the thyroid becomes underactive or hyperthyroidism when it becomes overactive.
Studies have linked PFAS exposure to autoimmune thyroid conditions such as Hashimoto's thyroiditis and Graves' disease. PFAS chemicals interfere with the immune system's recognition of thyroid tissue, causing the body to attack its own glands.
Multiple thyroid processes are disrupted by PFAS, including iodine uptake by thyroid cells, hormone synthesis, and enzyme activity. Studies on animals have demonstrated that thyroid cells undergo changes, and hormone concentrations change. Concentration influences the effects, with intermediate levels exhibiting the strongest association with thyroid dysfunction.
Residents near contaminated sites and military personnel exposed to higher PFAS concentrations show increased rates of thyroid disorders. These chemicals accumulate in the body over time, potentially triggering hormone imbalances and autoimmune responses that damage thyroid function.
We can help you file your PFAS-related thyroid disease claims
For over three decades, Environmental Litigation Group, P.C., represented toxic exposure victims, including veterans affected by PFAS contamination on military bases. Our team can assist you if you have developed thyroid conditions caused by PFAS exposure and have lived on a military installation for at least one year. Filing a claim against those responsible for toxic contamination may entitle you to financial compensation.
