"SPHL don't wish to depress you any more but the treatment for thyroid problems seems to be a Black Art.
My missus has a underactive thyroid and the treatment prescribed was increased incrementally until a desired blood reading was found. She went from being as lethargic as a dope smoker to as wired as a cokehead! She then took it into her own hands in the end and varied her pill intake until she felt OK. She'll be taking them for the rest of her days as I understand it. This was after going through the rigmarole of seeing a GP then a specialist and finally a third specialist"
For years I had a hypothyroid condition that had me low on energy to put it mildly. My AME got me referred to a Serious Medical Expert who put me on Thyroxine to raise the level. After 6 years of experimentation and second opinions I am now off Thyroxine as apparently my level is OK now. A BA 747 Captain with a similar condition was grounded by the Company as a result of negative cardiology results [ the two seem somehow linked] Four years later with views from another cardiologist he was fully reinstated. Flew 747-400's until he retired last year.
IMHO Thyroid conditions need more than one view and whatever the intial findings I would get a second or even third opinion for what it's worth. The heart seems to do odd things with low thyroid levels in some people.
I was always told that once on Thyroxine that was it for life.
