my daughter is 13 weeks pregnant and has a tsh level of 3.  her T4 level is 15.1 she is aware that this tsh level may cause neurological problems in her unborn baby and other problems.  is this serious enough to consider terminating a pregnancy and how likely is this condition to affect her baby.
Hithanks for using Chat Doctor. Her TSH level is on higher side according to her gestational period, but you mention T4 that is 15.1, is not sufficient as we need free T4 level. If free T4 level is on lower side that mean she is suffering from Hypothyroidism and need levothyroxine after consulting an endocrinologist. Hypothyroidism in pregnancy if left untreated can cause neurological problem in unborn baby.  I don't think that this level you think of terminating the pregnancy. You keep continue watch over TSH and free T4 level and take levothyroxine if indicated or advise by endocrinologist. Thanks
