I have been on thyroxine since total thyroidectomy 3 years ago. I am usually on 100mcg but whenever I go on a diet and start to lose weight, my blood test suggests (and GP orders) a reduction to 75mcg. At which point the weight loss stops and reverses. Weight goes back up and I ultimately return to 100mcg thyroxine per day.
I have recently started a new diet, then was sent for annual blood test. GP's secretary phoned yesterday to say I must immediately reduce my dose to 25mcg. (75% reduction!!). I queried this (frankly I'm horrified) and have arranged to go in and speak to GP next week and get my results.
Can anyone tell me if this could be correct? I have been feeling fine on 100mcg. Should I do as I'm told until I see the GP, stay on 100mcg or reduce to a halfway point?
I finally got my results which were FT4 25.8 and TSH 0.09 (they didn't measure FT3)
I spoke to another GP at the same surgery over the phone and he has agreed to me to dropping 12.5mcg (alternating 100mcg/ 75mcg) which I am happier with. No-one has admitted that they made a mistake and no-one at any point actually asked about my symptoms or how I felt
