Treated for Hypothyroidism but still exhausted

[MikeGoodwin]

At 19 I was diagnosed with under active thyroid (was completely fked actually) - dad was diagnosed at so I had to go get checked. Anyways I take 200mcg Thyroxine a day and for many years I was fine (difference was incredible) and yearly blood tests proved fine. I'm now 26 and over the last year or two Ive been fairly tired some weeks, but blood tests were fine and despite mentioning I didn't feel normal the GP insisted I was ok.

Now the last 3 months I have been abnormally tired, and in the last month I have been on the verge of exhaustion as I was before I was treated (feel like Im taking about 0.5mcg Thyroxine a day or something...). I'm going to book a blood test which may turn up 'fine' again but I know this isn't normal. I've added an alarming amount of body fat and noticed my skins got quite dry in places and can I bks concentrate to save my life during afternoons at work. I also suffer when lifting weights in the gym as though I am a heavy smoker that cant breathe and some days I've had to go home early half way through as I'm completely exhausted.

Ive done some Googling (pro research...) and the gist is I may not be converting properly and need to change medication to T3 or something, but need to see an endo as the GP basically wont give a toss.

Has anyone done this? I get the feeling I am going to have to make a real effort to try persuade them to let me live a normal life.
