Though there are chances of hampering growth of brain of baby in hypothyroidism
, there are equal chances for normal development also. If T3 & T4 levels are normal, chances of affecting brain growth are reduced (though not to zero). Whether to continue pregnancy
or not, it depends on how easily/with difficulty you became pregnant. If you became pregnant very easily & don't want to take any chance, you can go for abortion
. Equally, if you conceived with difficulty & are ready to take that extra risk to baby, you can continue pregnancy. Your physician will assist you in decision making.
Wish you good health.
