How much does your TSH level vary?

Heya Neil, 

It does fluctuate as we use our T4, convert to T3, then top up our meds again. I'm not entirely sure of a normal range of fluctuation however I'm afraid. 

However, if you have a look through some of the recent discussions, then you'll find a few of us have had increases in our TSH recently. So the standard questions to ask first are:

• Have you put on any weight since your last blood test? 
• Have you started taking any new medications? 
• Have you started taking any new supplements? 
• Have you changed when you take your thyroxine? 
• Have you changed what or when you eat/drink after taking your thyroxine?
• Have you definitely taken your thyroxine every day?

If nothing is different, then I'd wait and see what happens at your next test. Maybe have your GP run a TFT in 3 months to see what's happening. Then take it from there.

Thanks for your reply Lass.  The strange thing is that none of those things you listed have happened.

I've had a good chat with the GP and we decided to increase my dosage a little from 175 daily to 175/200 every other day and do another test in 3 months to see where we are.
