Practical Pearls

Why TSH 2.5?

In the first trimester, high levels of human chorionic gonadotropin (hCG) act on the TSH receptor, leading to a physiological suppression of TSH. Therefore, the upper limit of normal is lower than in non-pregnant adults.

Levothyroxine Dosing

Pregnant women with hypothyroidism require a 20–30% increase in their levothyroxine dose as soon as pregnancy is confirmed, primarily due to increased TBG (Thyroxine-Binding Globulin) levels driven by high estrogen.
