Q
What abnormality in TFT whld u expect in the first trimester of preg and why?
When would you expect it to normalise?
A
High levels of beta-human chorionic gonadotropin (HCG) have an action similar to thyroid-stimulating hormone (TSH), leading to mild biochemical thyrotoxicosis. Triiodothyronine (T3) is rarely elevated however.
Antithyroid drugs have no effect at all on the prognosis of the condition, and thyroid function tests usually return to normal by week 20.
