In 2009 my TSH was 3.5, by 2010 it was up to 6.0, and now (mid-2012) it's at 7.1. i.e. A rapid climb from highish to very high. My free T4 and free T3, however, have been consistently normal, so my Pituitary gland seems to be coming to the party.
My current status is:
- TSH: 7.1 mU/L (0.4-3.5)
- Free T4: 16.4 pmol/L (9.0-19.0)
- Free T3: 4.2 pmol/L (2.6-6.0)
What could be going on? How concerned should I be? What is the best way to approach this?
The thing is, I feel absolutely fine! Really quite good and perfectly healthy. In fact, I feel better now than in previous years, experiencing my first ever Winter when I have not really suffered with the cold the way I have my whole life prior, despite being technically hypothyroid.
I am 43, female, and all of my other blood tests make me look like a star student - normal across the board.
Thanks for any insights
