I would be grateful if someone can help me here.
Two years ago I was diagnosed with Hashimoto's and have had incremental increases in levothyroxine. However, my T3 was always below range. My reading in August of last year and when I was on 75mcg of thyroxine was:
Free T3 3.8 (4.0 - 6.8)
Free T4 18.6 (12.0 - 22.0)
TSH 1.8 (0.27 - 4.20)
Clearly my T3 was below the range. I increased my thyroxine by 12.5mcg three months ago as I was still having symptoms of hypo: constipation, dry skin, hair loss and feeling cold.
Today I received my recent readings and was astonished to find the readings are now:
Free T4 25.3 (12.00 - 22.00)
TSH 0.55 (0.27 - 4.20) !
No T3 was done by GP.
Vitamin D2: <7 nmo
Vitamin D3: 131nmo
Serum Vitamin D: 131nmo (25.00 120.00) !
Serum Ferritin: 123ug (13.00 - 150)
Calcium: 2.54mmo (2.20 - 2.60)
I take Calcium, D3, Iron, K2, supplements as well as a good multi vitamin and it seems that my vitamin D is over the range. I will cut back.
I cannot understand how my T4 could increase so much when I only increased the thyroxine by half a 25mcg tablet and I am still getting symptoms and in particular hair loss, eyelash loss and feeling cold. Could it be because I have been taking supplements over the last eight months? The reason I increased the thyroxine dose was because from the earlier readings my T4 wasn't converting to T3.
My GP has arranged for me to go back to the endocrinologist who I saw last year and hopefully they will take a T3 reading. But I am puzzled as to what is going on.
Could some one please offer an explanation for me. I'm trying so hard to get my diet right and everything else - I really feel its one step forward and two back.
