What causes THS to jump?

I was able to get my THS down to 1 about 7 months ago.  My latest bloodwork came back with it at 5.27, which is close to what it was when I was first diagnosed a year ago.  I take my medication on time, everyday.  I don't think I have ever missed a dose.  My FREE T4 was at 1.0.   I currently take 50 mg of Levothyroxine and 5 mg Cytome

Are you under a lot of stress? I was went from .4 to 12 in one month, then I managed to get the stress levels down and went to a 5.6. I started walking every day too. Hope this helps. 

Actually, I am under a lot of stress.  I also started anti-depressants.  So maybe it is a combination.  Thank you!
