A brief introduction. Diagnosed papillary carcinoma 2008 thyroid and a good number of lymph nodes removed. Three sessions of radioactive Iodine. 250 mcg Levothyroxine reduced to 225 mcg because of palpitations and other issues.
Can't sleep very well, aches pains, loss of strength, shakey hands, always cold etc. all of which could be down to getting older. Endocrinologist not concerned so I made some enquiries on my own.
Low Vitamin D
B12 (lower part of range)
FT4 18.1 <11.5 -22.7> pmol/L
FT3 4.5 <2.8 - 6.5> Pmol/L
I posted these results on another forum and they suggest I have rT3 issues and to resolve this I need to drop my T4 dose to 50mcg and then slowly add T3 so I can get to an optimal level whilst working on my other problems.
Dropping to 50mcg T4 is a bit scary. My TSH is fully supressed and needs to remain so (my main concern) T4's long half life means I'll be OK for a few days at least which gives me time to raise my T3. From what I have read I should start on 5mcg T3 dosing three times a day (25mcg tablets) and build up to slowly to 15mcg three times a day. So that would be 6.25mcg to 12.5mcg dependent on how accurate my cutting is.
Has anybody else been through this process and can give me some guidance? Will just short of 20mcg/day be enough? Do I need to raise my T4 beyond 50mcg and if so when?
