Over- and undertreatment of hypothyroidism is associated with excess mortality. A register-based cohort study.

Conclusion Mortality was increased in untreated, but not in treated hypothyroid individuals, independently of age and severity of hypothyroidism. Duration of decreased TSH in treated individuals had a greater impact on mortality than did duration of elevated TSH. These results stress the need for close monitoring of treatment in individuals receiving thyroid hormone replacement therapy. PMID: 29631518 [PubMed - as supplied by publisher]
