hypothyroidism during pregnency

[shilpa856]

i am 24 yrs old. i was diagnoised as hypothyroid 7 yrs ago. now i have a 2 yr old son who is all fine.I am under medication till now(100mcg).now  want to plan another baby. But my TSH level was 102.4   two months back and even my T3andT4 was also abnormal... but now after taking 100mcg of thyroxine it is to normal levels.... is it safe to plan my pregnancy now or should i postpone it for some more time.... is there any risk for the baby if i get preg now........ Wat is thyroid cancer, thyroidities,........etc... is there a chance for a hypothyroid person to get that.....

It is essential to regulate TSH prior to trying to conceive. Would recommend repeating TSH 4-5 weeks after the most recent "normal" level.  Target in this setting (for our lab) is 0.3-2.0.  Anticipate needing about a 25% (or more) increase once you are pregnant and work closely with your doctor to keep it regulated during pregnancy.  

There is a of post-partum thyroiditis (brief over-active thyroid) -but your history suggests this is not likely as there appears to be little to know functioning thyroid (TSH about 100 off meds!).

Hi. I just had a baby July 09 and I'm Hypo. You need to make sure your levels are in good range before you try and get pregnant, then as soon as you know you are pregnant you want to make sure you get your levels checked. You want to make sure you are level throughout your whole pregnancy, because your hormones will be going crazy. I was normal throughout my whole pregnancy, now after deliverying my TSH level is very very low.
Good Luck and Happy Baby Trying.
