If a patient with Hashimoto's thyroiditis experiences an infection, which consequence is most likely?

💡 Explanation

In Hashimoto's, thyroid tissue is already damaged. Infection can trigger increased immune activity, including cytotoxic T-cell responses that further damage thyroid cells, reducing thyroid hormone production because the inflammatory cytokines inhibit thyroid peroxidase (TPO); therefore, thyroid hormone levels are likely suppressed further, rather than increasing or impacting unrelated hormone regulation.
