Dear sir, regards!, the story is quite usual. Any hypothyroid women, stable on a certain dose, once she becomes pregnant, her thyroxine
requirement increases to meet the increased demands of pregnancy
. few things to clarify -
1. initial weeks of pregnancy , hyperemesis phase might mimic hyperthyroid status. So in hypothyroid women the dose remains stable.
2. Once hyperemesis phase is settled, thyroxine requirement increases, so the dose has to be escalated.
3. Any progesterone
preparation will alter hormonal
milieu so T4 will change, so please check FT4 for thyroxine dose titration.
