The Claim
Elevated free T3 and free T4 levels are positively correlated with increased bone turnover markers, but not correlated with bone mineral density at the radius in this cohort.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Higher levels of thyroid hormones free T3 and free T4 are associated with increased bone turnover, but not with lower bone mineral density at the radius in this group of people.
See the scientific wording
The severity of hyperthyroidism, as measured by elevated free T3 and free T4 levels, is positively correlated with increased bone turnover markers, but not directly with bone mineral density at the radius in this cohort.
Too much thyroid hormone makes bone cells break down and rebuild bone at the same time, but the breaking-down part happens faster than the rebuilding, so bone gets weaker even if the overall density doesn't drop right away in the forearm.
What the research says
1 studyWhen men have too much thyroid hormone, their bones break down and rebuild faster, but their forearm bone density doesn’t always drop in a way that directly matches how high their hormone levels are. The study found this pattern.
