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.

Support is ahead, but a single strong opposing study can change this.

In plain English

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.

Why this might work

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 study
  1. Study: Impact of severity, duration, and etiology of hyperthyroidism on bone turnover markers and bone mineral density in men

    When 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.
