I've been self medicating the last 3 years for low fT3 including all symptoms of hypothyroidism, but because my TSH always was within ref.range although in the high end, my endo wouldn't start treatment, but my GP was supportive of me self medicating.
The last year I've been on T3 only, 50mcg/day with good results clinically.
Last September I ran out of medicine due to a delivery lost in the post system and I thought it was s good opportunity to have a blood test done without medication.
After 9 days without medicin with all symptoms of hypo returning:
Vitamin B12.P: 679 pmol/l MIN: 200 MAX: - (FR)
Thyrotropin [TSH].P: 8,69 (0.65-4.8)
FT4,P: 8,4 pmol/l MIN: 12,0 MAX: 22,0
FT3,: 4,2 pmol/l MIN: 3,1 MAX: 6,8 (FR)
Vitamin D;P: 84 nmol/l MIN: 50 MAX: - (FR)
Endo concluded that I do have myxedema, but wanted additional test done without medication
Resumed my T3 medication as usual 50mcg/day until January 1th.17
New test 15 days without medication (all hypo symptoms returned, but later than last time)
January 16th. 17
TSH 4.58 (0.65-4.8)
fT4 9.1 (12-22)
fT3 3.3 (4.1-6.9)
Does anyone have an idea of what is going on? Suggestions much appreciated.
I'm going to see the endo soon, but would like to have a little clue of why the change in TSH and fT4, fT3.
