Abstract

Thyroid function in early pregnancy has been reported to be slightly different from that in second or third trimester: We assessed thyroid function before and after induced abortion in normal pregnant women. A significant increase in serum Free T4 and a decrease in serum TSH were observed before abortion and these changes, apart from the contemporary significance of serum hCG-β, were especially marked in pregnant women with nausea and vomiting. On the other hand, an increased level of Free T4 and a reduced level of TSH returned to the normal ranges 7-10 days after induced abortion. Futhermore, serum hCG-β was significantly reduced. These results suggest that, in normal early pregnancy, thyroid function may be related to serum hCG-β concentration and its increased level, which induces gestational emesis.
