Hi Joan! I too am deaf as well as having this bloody graves now hypo. My type of deafness is the osteclerosis thing which is hereditary and affects the main speech decibels my loss is 75db on the 1000hz(bugger it) But the consolation prize is you learn to talk well because your deafness worsens as you get older. Can you tell me where you got your information about thyroid hormones affecting calcium etc? Was it a book? Do you have the eye problems (because I was deaf my endo said the RAI wouldn’t be the best option for me surgery would be better – what happened with you?) Sorry about the questions.
