Hypothyroidism and infertility

[Sam222sa]

Hi,

I have hypothyroidism and I take levothyroxine 75mcg.

I also take a high quality multivitamin for support.

I am trying to conceive.Can someone please tell me which vitamin tests I should be asking my doctor apart from ferritin,vitamin D,folic acid and iron?

TIA

Welcome aboard

If you could fill in your profile with some history and any test results you have that would be really helpful (including ranges) I'd add folate and B12 to your request

We've yet to find a good multi vit as they tend to have too much of things we don't need and too little of the things we do and if it contains iron it will block uptake of the other things anyway 😬 also many contain iodine which isn't ideal

Another TTC hypo posted today, and I shared this response - relevant to you too!

I have not been TTC or pregnant & hypo at the same time but have done a lot of deep dive reading on it.

You might want to search this site for TTC, as there are blood measures discussed for best chance not to miscarry.

But what I just wanted to pipe in to say is regards to your FT4 when you do conceive.

It’s very important to keep your FT4 up… to have it definitely well over mid range, if not 75% through range, while TTC.

Because

Your baby won’t have the ability to make their own thyroid hormone until mid-gestation (20 weeks), so the baby will rely entirely on yours.

But most importantly, week 5-6 after conception the baby goes through the most important neurological development of the whole pregnancy. continuing through about week 10 or so, and this neurological development demands sufficient thyroid hormone.

Since most people might not even know they’re pregnant til a week or so before that, if your ft4 isn’t high enough already, you won’t be able to bring it up in time for the demands of week 5.

So while you manage your thyroid numbers to TTC, keep an eye on the time when you will actually be TTC, because you’ll want to keep your FT4 up. Also, about 85% of pregnant women need to increase their Levo regularly through the pregnancy. So just keep in mind as time flies : )

welcome to the forum

75mcg is low dose unless you’re very petite

What were your last thyroid results

TSH, Ft4 and Ft3

You need to test vitamin D, folate, B12 and full iron panel including ferritin

ALWAYS test early morning, ideally before 9am, only drinking water between waking and test and last dose levothyroxine 24 hours before test

Pregnancy guidelines

NICE guidelines that if hypothyroid or subclinical you should see endocrinologist BEFORE TTC
