Dr. Lazarus shares how a fetus could be affected by a low thyroid-stimulating hormone (TSH).
A low TSH won’t have too many affects unless the pregnant woman is hyperthyroid, i.e. an overactive thyroid, and in that case there is a danger of miscarriage and problems, obstetric problems, but a low TSH in early pregnancy is quite common and does not signify anything terrible. It’s more important to worry about a high TSH in early pregnancy.
