Tsh spike in results

I had my tsh tested in December which was 1.7 but after a ivf round a month later the clinic tested my tsh and it was 11 .

Gp has upped my throixine from 150mg to175mg and retest in 6 weeks.

Any ideas why it would jump so high?

Do you have autoimmune thyroid disease/Hashimoto's?

[Hidden in reply to SeasideSusie]

Yes it's been mentioned before as one of the ivf clinics checked for it, but as usual no one really explains it

[SeasideSusie Remembering in reply to Hidden]

When you have Hashi's, antibodies fluctuate and cause fluctuations in symptoms and results. You could have been having a flare up at the time when the TSH was so high.

From what I understand, a TSH below 2 is necessary for a successful pregnancy, I'm afraid I don't know what's best when trying to conceive. There are other members who know much more about this so you might want to make a new thread and put about IVF/conception/pregnancy or similar in the title to attract their attention.

If you don't know anything about Hashi's, it's helpful to reduce antibodies, thereby reducing the frequency of flares. Adopting a strict gluten free diet and supplementing with selenium L-selenomethionine 200mcg daily can help needed antibodies, as can keeping TSH suppressed which would be a good idea all round for you as you're hoping to become pregnant.

Mine went from 30ish to 5 on no levo. I think tsh can fluctuate when there is autoimmune activity.

Thank you, it's all very complicated with no gp seeming to give a straight answer. I've been on throixine nearly 20 years at one level or another and twice it's been caught fluctuating like this that I know of 😒. I know they used to question weather I'd been taking my medication obviously why they asked

[puncturedbicycle in reply to Hidden]

It isn't supposed to happen if you're optimally treated. Autoimmune activity is meant to slow down and level off and tsh should be stable, but mine is always up and down after how ever many years (8? off the top of my head) of treatment. But not as dramatically as yours.

They are convinced that fluctuation comes from non-compliance! So you wouldn't be the first.

The gp this morning was lovely but didn't seem to have a clue like a lot of them.. it's so depressing that I can never get a clear answer off option.

Thank you for your help

IVF treatment is known to cause thyroid problems in some women. It's the flow of hormones you'll get injected within a short period of time (ovarian hyperstimulation).
