I am currently on 100 mg of Levo after routine thyroid bloods 12 weeks ago (still in 1st year of diagnosis) & finding my TSH was up to 14, which is higher than at diagnosis of Hashimotos (have had TPA test so know I have autoimmune thyroiditis or hashis) back in April.
Gp upped my dosage from 50 mg to 100 mg at this stage & had bloods done again 4 weeks later & TSH was down to 2.2, bang in range according to GP. Well of course I was quite pleased about this but it did concern me that my TSH had gone from 14 down to 2.2 in 4 weeks! I asked my GP at the time if there was a chance I could go overactive as TSH had come down very quickly on 100 mg & he wasn't going to take bloods again for another 8 weeks! He said it's possible but unlikely in my case as my initial diagnosis with full thyroid blood panel earlier this year revealed that my thyroid is being destroyed quiet aggressively..the rate of destruction or something as measured by the TPA.
So should I be worried about going overactive?
I am due to have bloods done again in 2 weeks.
