I have
thyroid for over 5 years now. I used to take thyronorm 50mg. I did a thyroid test in feb 23.
TSH: 9.12uLU/ml T3:1.28ng/ml T4: 11.37ug/dl. My doctor prescribed Euthyrox 75mcg.
I did another thyroid test in June 23, my TSH was 0.218uLU/ml. Continued Euthyrox75mcg. I did another thyroid test in July 23, my TSH was 12.01uIU/ml. Still on Euthyrox 75mcg.
How is my TSH varying from so much in a matter of 1 month?
