One month ago my TSH was suppressed (below 0.1) and T4 was at 17 (ref. 10-28), I was at 100 mcg of T4. I increased to 150 mcg this month and my T4 increased to 27.6 (ref. 10-28). However, my TSH is also increased to 2.4!! I was not comfortable having my T4 at this high level, so I dropped back to 100 mcg and I feel fine now.
My TSH results were almost always inconsistent with T4 levels. For the most part of last year, it was suppressed regardless of my T4 was mid-range or below. My doctor thinks I have pituitary dysfunction. MRI shows I have normal pituitary structure.
By the way he refuses to test T3 anymore! but from last year tests, it tends to follow T4 trends.
T4 helped my improve but I still face fluctuations in my hypothyroid symptoms. My doctor don't know how to control these symptoms! Any advice?
