Why Would Tsh Level Double In 11 Months, Then Again In The Following Few Weeks ?

[CW1]

Been taking Thyroxine for 7 or 8 years & all fine. January 2021 TSH Level was 2, by December it was nearing 5. About 6 weeks later, beginning of February, it's up to nearly 9. Other than the thyroid working less & less, is there another reason it could be doubling so quickly ?

Docs said to take an extra 25mcg a week (yes, a week), review in 3 months. Can't think that's enough to even begin stopping the upward trend, let alone get it down (though I know it needs to be increased slowly). Going to be a long while before this is back to where it was by only increasing every 3 months.

No.....I agree with the GP, the commonest cause is that your dose of Thyroxine is not large enough.

I would check that your DR. means 25mcgms a DAY,.........25mgns/week is *** all and will do nothing.

Definitely a week Sqad. I take 100mcgm Monday-Friday & 125mcgm Saturday-Sunday, been told to take 125mcgm Fridays too. Thinking I'll do it Mondays too. Can see I'll be on the higher dose every day ultimately, if not more.

CW1 do what your GP says.
Many things can raise your Thyroxine requirements including age and pregnancy, also some drugs, but the most commonest thing by far is wrong dosage of Thyroxine.

Do what your Dr. says....................

do as your doctor says for chrissakes
I think is admirable advice

PP - why are you so rude? I can accept that you are probably on the spectrum but really?

[MrsCheese]

are you taking it properly? An hour before eating/drinking and at least a few hours before other medication? Also are you taking anything that would affect absorption like PPi's? (omeprazole ect)

[CW1]

Taking it the same way I always have, as per instructions, at least 30mins before caffeine or food. I know that's not as long as you said, MrsCheese, but in reality I take it a few hours before, when I'm up for the loo early hours of the morning. Friend takes his *with* breakfast !

Only other "medication" is a vitamin D tablet, with breakfast.

I take on board "do as the GP says" but when it was tweaked before, it was increased 50mcgm a week, by a GP I know. I've never heard of this GP, she was looking it up on the Internet, so don't have much faith in her. As Sqad said originally, 25mcgm will do nothing.

[Sqad]

Oh! I shouldn't say this, but if I were in your shoes, I would increase your daily Thyroxine level so that you are taking 125 mgms every day, as you do at weekends.
I would not tell the doctor until my 3 month blood tests.

That is my opinion....I know I have given the opposite advice.....I know that this is the Internet .........but that is what I would do.

[Sqad]

OR......get the opinion of another doctor.
