Definition

Thyroid antibodies are immune proteins that attack thyroid tissue. The two most common are thyroid peroxidase antibodies (TPO) and thyroglobulin antibodies (TgAb), which are elevated in Hashimoto's thyroiditis, the leading cause of hypothyroidism. TSH receptor antibodies (TRAb) are associated with Graves' disease.

Why It Matters

Testing for thyroid antibodies helps diagnose autoimmune thyroid disease before significant thyroid damage occurs. Elevated antibodies indicate ongoing immune attack on the thyroid, which can worsen over time if left unaddressed. Early intervention can reduce antibody levels, preserve thyroid function, and prevent progression.

Frequently Asked Questions

Elevated thyroid antibodies indicate an autoimmune attack on the thyroid, most commonly Hashimoto's thyroiditis. This means your immune system is targeting thyroid tissue, which can lead to hypothyroidism over time. Early intervention can help reduce antibodies and protect thyroid function.

Yes. Strategies include eliminating gluten and other food sensitivities, healing the gut with probiotics and anti-inflammatory nutrition, optimizing selenium and vitamin D levels, managing stress, reducing toxic exposures, and using immune-modulating herbs like ashwagandha and turmeric.
