Hi, I had a total thyroidectomy ten years ago because of thyroid cancer (pappillary carcinoma)
I have since been on 150mg thyroxine daily and my bloods are usually stable (except during pregnancies)
This year my bloods have come back as hyperthyroid borderline thyrotoxicosis... on numerous occasions..
(to note.. this year I have also been diagnosed with CKD stage 3 ..B12 deficiency, anemia, hiatus hernia, urine retention and overactive bladder.. so my health has been quite bad to say the least, however my thyroxine intake has not changed)
My question is, if my thyroxine intake hasnt changed, and I have no thyroid gland...what could be causing me too be hyperthyroid?
