British Medical Journal Study: Thyroid Drug 'Boosts Risk of Fractures in the Elderly'
BBC News -- Many elderly people may be taking "excessive" medication for their thyroid problems, increasing their fracture risk, researchers warn.
A synthetic hormone, thyroxine, is given to people whose thyroid glands produce too little naturally.
But writing in the British Medical Journal, researchers say having too much boosts fracture risk and doses may need to be reduced as people age.
