hypothyroidism mismanaged first trimester pregnancy

by SHB6, Oct 14, 2007 12:41PM
I am currently 18 weeks pregnant and am a hypothyroid patient who takes Synthroid.  Prior to conception and during my first trimester, I took Synthroid (75mcg) but my thyroid condition was not managed properly.  My TSH level 2 months prior to conception was 3.5.  At 6 weeks of pregnancy, my TSH was 5.3.  Unfortunately, this was not discovered until week 13 of pregnancy at which point my Synthroid dose was increased.  TSH levels after 2 days on the new dose was ~2.  I am now being monitored by an endocrinologist.  I would like to know what risks my baby has as a result of my thyroid mismanagement (I understand there could be developmental/cognitive delays?).  I would also like to know about how high my TSH levels may have risen the in 7 weeks that I wasn't being properly managed.  Thank you.

There are small risks of neurological development problems but typically not seen with only slight increase in TSH.  It is hard to speculate how high the TSH may have become before the dose was increased resulting in the current acceptable level of around 2.  Would keep a close eye on things and recognize that most pregnancies with mild under-treated hypothyroidism go very well.
