What Is Causing Elevated TSH In My Blood?

My TSH is 7.35, FT4 is 1.2, FT3 is 211. I don't want to go on higher dose of synthroid 88mcg presently. It was raised from last year 75mcg none of my symptoms disappeared when it was raised. I tried cytomel can't take it. I suspect it is my adrenals. Any other ideas. Thanks

Hi,
Thanks for asking.
Based on your query, my opinion is as follows.
1. Reduced thyroid hormone levels is causing elevated TSH due to positive feedback.
2. If thyroid hormone levels are normal with thyroxine therapy, the TSH level will come back to normal.
3. If the TSH level is normal, all your symptoms will disappear. There is nothing wrong with increasing thyroxine levels, as it supports your overall body function.
4. Adrenals are related to steroids and adrenaline hormones. They do not have any effect on thyroid. Possible autoimmune thyroid damage or iodine deficiency maybe the cause. Cytological and immunological study of thyroid may be helpful in identifying the cause.
Hope it helps.
Any further queries, happy to help again.
