In the context of longevity, observational studies have noted that slightly elevated TSH (subclinical hypothyroidism) is more common among centenarians, possibly as a protective mechanism against oxidative stress or hypermetabolism. However, the evidence is largely associative, not causal. No interventional trials demonstrate that raising TSH extends lifespan. Moreover, untreated hypothyroidism carries cardiovascular and other risks. A blood TSH test reflects current thyroid status but does not directly measure longevity. Genetic variants affecting TSH (e.g., PDE8B, TSHR) have small predictive effects. Conclusion: TSH is a useful biomarker but not a standalone longevity indicator. Evidence is moderate, based on human observational data. Abnormal values require medical follow-up.","area":"gesundheit","canonical_id":"gesundheit:canonical-201d03ccffe1b635fca4e43e","id":"public-9693a6689ce5487f621288de","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Evidence check: TSH in the context of Langlebigkeit","score":21.10041968,"snippet":"TSH (thyroid-stimulating hormone) is a standard clinical marker for thyroid function.

Generally, TSH is a key marker of thyroid function. An optimal TSH range (approx. 0.5–2.5 mU/L) is associated with better cardiovascular health and longevity, while both subclinical hyper- and hypothyroidism may be linked to increased mortality. The evidence is based on epidemiological studies, not randomized controlled trials. Direct causal effects on lifespan are not established. Consumer DNA tests cannot measure TSH levels; they only detect genetic variants (e.g., in PDE8B, TSHR) that have a small influence on TSH levels. These effects are minor and usually clinically irrelevant. A purely genetic assessment of thyroid function is insufficient; blood values and clinical symptoms are essential. The evidence for a direct longevity effect of TSH is therefore rated as 'unclear' or 'mixed'.","area":"gesundheit","canonical_id":"gesundheit:canonical-2e8649accbd3540daf99f3a1","id":"public-f999d2e6fb7662201e92614c","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Evidence check: TSH Schilddrüse in the context of Langlebigkeit","score":20.98389251,"snippet":"The provided knowledge sources contain no specific information on TSH (thyroid-stimulating hormone) in the context of longevity.

FT3 is a thyroid hormone that regulates metabolism, and human observational studies suggest that low FT3 levels may be associated with increased mortality in older adults (e.g., euthyroid sick syndrome). However, the evidence is complex: low FT3 can indicate poor health prognosis, but slightly reduced FT3 in aging is also discussed as a possible adaptive mechanism.
