Pregnancy and TSH suppression

Hi . Welcome back to the Online Community and many congratulations on the news of your pregnancy.

I can understand your worry so until any of the members of the group here come back it might be a good idea to put your question to Ask a Nurse here on the forum but you may need to wait two or three days for a reply.

Sending all the best, Bxx

Hi Lauren,
I recall that there's a need to modify thyroxine doses during pregnancy and that the 'right' amount of thyroid hormones is crucial to good foetal development. That said, I can't remember if it's too much or too little that can cause the problems. From long ago memories - that might be wrong - I think it's more typical to relax the TSH control a little bit but you'd need to check. 

As you get bigger, you will need to keep adjusting the dose to stay at the target TSH. We all find that as our weight goes up or down, it's normal to have to tweak our doses.

My question to you would be whether it's really the 'antenatal endocrine' specialist who has made this decision, or - and this is more desirable - that the cross-functional Multi-Disciplinary Team makes that decision. The endo may not know the oncological side of the equation and you want a multi-skilled team to take that decision for you.

If the MDT agreed this approach, then I'd go with 'trust the experts when there are a bunch of them from different disciplines'.
