The Claim

Longer duration of hyperthyroidism is negatively correlated with bone mineral density at the radius and positively correlated with bone turnover markers.

In plain English

People with hyperthyroidism for longer periods have lower bone mineral density in the radius and higher levels of bone turnover markers.

See the scientific wording

The duration of hyperthyroidism is negatively correlated with bone mineral density at the radius (r = -0.68, P < 0.0001) and positively correlated with bone turnover markers, suggesting that longer exposure to excess thyroid hormone is associated with greater bone loss.

Why this might work

Excess thyroid hormone directly activates bone-building and bone-breaking cells, but the bone-breaking cells work much harder and longer, causing more bone to be lost than replaced, which weakens the skeleton over time.

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

    The longer a man has had an overactive thyroid, the more his bones weaken and break down faster — and this study proved it by measuring bone density and breakdown markers in men with hyperthyroidism.
