my baby girl born in 32 week preterm had thyroid , now she is 4 year old. as doctors guided we should slow the medicine dose and was about to stop medicine. suddenly now she had an increase. now doctors saying it could be because of eye infection sudden thyroid spike so asked us to check again after 2 months, else will have to take life long medicine. I am really worried.. please let me know in today's age is this really incurable and has to be life long on medication.
