High tsh in pregnancy

[jinglebellmel]

After 2 consecutive miscarriages I've just had bloods back with a tsh of 5.75 suggesting hypothyroidism. Dr isn't willing to do anything until after a repeate test in 4 weeks.

Does this sound right? Is 5.75 not that high? I've read that it should be under 2.5 for a successful pregnancy am I'm worried in 4 weeks it may be too late and I'll already have miscarried. Do you think I should push this further or am I over reacting and being a nightmare patient? Thanks

Thanks violet, that's very interesting! So it's possible that my thyroid is okay normally and just goes a bit crazy during pregnancy? Hopefully I'll get to see the endocrinologist soon and can ask some questions.

It's hard to tell which is why they initially wanted to wait and see.

I think ideally an antibody test would be good to see if you have autoimmune thyroid issues which may mean you're thyroid gives up the ghost in the future.

However, if tsh is rising during pregnancy that's not good, even if no miscarriage, so being under an endo or obstetrician or both is good.

Being on the 25 is no big issue but you might find you get a bit wired and need to come off if your thyroid recovers.

But your thyroid must be absolutely under 2 to conceive, so regular monitoring if the next year going to be key in either scenario.

Thanks violet

You are sorted but if anyone else is reading this, one if the links on the link below reads

"Women undergoing evaluation for infertility
These women should have thyroid tests as part of the work up for infertility. If hypothyroidism (overt or subclinical) is detected this should be treated aiming for a TSH of less than 2.5 mU/L or TSH within the first trimester-specific reference range if such ranges are available locally."

The British thyroid foundation is the charity associated with the British thyroid association of endocrinologists, who have set out the nice guidelines. The BTF is advised by them. So basically this is what an endo would say, if a GP is questioning it.

Gps (and any Dr not an endo) aren't used to dealing with this though so often aren't that knowledgeable.

(Sorry I get quite ranty about this; I had a nightmare during pregnancy and the BTF really helped me out)

It definitely seems as if GPs aren't very knowlegable in this area (not a criticism I know they deal with such a vast array of conditions). But people need to know the facts and be able to question and push for proper treatment. Sorry you had such a hard time with it violet.

Oh yes definitely.

My new GP said "we (gps) aren't great and dealing with thyroid issues" - as he knew they find it confusing, which it is. There's been a lot of changes in the last 10 years that aren't always well known about.

Hi ladies, you were all so helpful last week, hoping you can help again. I got my tpo results back today, they were 7u/ml. The reference on the report says

That's a tricky question as I personally don't know if everyone has a few low antibodies or only people who do have or will get hypothyroidism. Below range is encouraging at the moment and either way you're being treated at the moment

If it's very low then it must be ok however something is potentially amiss if pregnancy is causing tsh to rise I think, but whether that's antibodies or other I'm not sure.

Thyroxine has a long half life so it takes at least 6 weeks or more to build to the correct levels and impact on tsh. The earliest they must be able to test must be a month (though I did have it 3 weeks apart in pregnancy but that might be different.)

This is why thyroid tests will be about 6-12 weeks after a dose change.

The q I'd ask the GP is whether that result could rise, which it could - I've had negative antibody test for coeliac and it had no score. They've tested a few times as they said it could spontaneously start (I've had some weight gain issues or lack of and anaemia)
