Why Do TSH Levels Drop After A Hiking Vacation?
I am on Levothyroxine 125 for 4 years (post i-131 therapy for Grave s) and every time I come back from a hiking vacation trip( 1-2 weeks long) my TSh level drops below 0.3 eventhough I keep taking Levothyroxine the same way.Is there an explanation or anyting I can do about it, because I have hyperthyroid sympthoms for quite a while after my trips?

Hello,
Your case sounds interesting.
Usually the TSH level needs a six weeks period to change. Ft4 and Ft3 level give a much specified information regarding to faster changes.
So if you checked the TSH level just when you got back from hiking it doesn' t mean that it reflects the fluctuations of the last weeks.
So, you have to lower the doses and recheck it after six weeks.
Hope the information will help.
