Thyroid hormone therapy in a population cohort over two decades indicates persistent overtreatment

TH therapy in the study population increased over the past two decades. TSH measurements revealed persistent overtreatment, particularly among older individuals. These findings highlight a concerning gap between updated guideline recommendations for TH therapy and its implementation in routine clinical practice. Greater emphasis is needed on translating scientific evidence into patient care through improved education of both physicians and patients, promoting a more restrictive approach to thyroid function testing, TH therapy, regular review of ongoing TH treatment, and age-adjusted TH dosing.
