infertility

[Jaime623]

My question is I had papilary thyroid cancer & I had my thyroid removed in 2006.
A month after having my thyroid removed my doctor did Radio Active Iodine treatment
And everything has been good in October of this year he chose to do the Radio Active
Iodine again & again all my tests came back negative thankfully so he gave his consent
to try to conceive another child I am going to see a fertility doctor next week my question
to you is what do you think the chances of me having a succesful pregnancy are?

Why did you have your thyroid removed ?

I am also trying to conceive after thryroid surgery 5 months ago.  My dr. told me that you have to increase synthroid when pregnant because the placenta eats into the synthroid.  You should let your dr. know as soon as you are pg!!!

Hi Jaime,

Good luck with your planned pregancy.  From what I have seen the increase in thryoid meds is usually by 25 - 40%.

You should discuss with your Dr. in advance of getting pregnant.  I also understand that the increase in thyroid meds will start pretty soon after conception.

Make sure your TSH is at optimal level (I think usually around 1) before you TTC.

There is some good info about pregnancy and hypothyroid on the Mary Shomon thyroid site.

Best wishes

Sally

Thank You for your advice. Would my synthroid need to be adjusted
alot  during pregnancy? I am on 150 mcg now. And does that dose stay
the same will trying to concieve?
Thanks Jaime

The chances should be quite good from a thyroid standpoint and it has been 6 months since RAI - so should be safe -- make sure the levothyroxine dose is monitored/adjusted closely during pregnancy.
