Thyroid hormone homeostasis in levothyroxine-treated patients: Findings from ELSA-Brasil

CONCLUSION: The present results challenge the dogma that treatment with LT4 for hypothyroidism restores TH homeostasis in all patients. A substantial number of LT4-treated patients exhibit repeated FT4 and FT3 levels outside the normal reference range, despite normal TSH levels. Further studies are needed to define the clinical implications of these findings.PMID:38506164 | DOI:10.1210/clinem/dgae139
