Thyroid Disease in Pregnancy Uncontrolled thyrotoxicosis and hypothyroidism are connected with negative pregnancy outcomes. Similarly, there is issue about the effect of overt (ie, symptomatic) maternal thyroid disease and even subclinical maternal thyroid disease on fetal development. In addition, medications that affect the maternal thyroid gland can cross the placenta and impact the fetal thyroid gland. This document evaluates the thyroid-related pathophysiologic modifications that take place throughout pregnancy and the effects of subclinical and obvious maternal thyroid disease on maternal and fetal results.

Thyroid ultrasound is widely offered but extremely observer-dependant during infancy. Although diagnostic precision is enhanced with using colour Doppler, ectopic thyroids are discovered less dependably as compared to scintigraphy6. Brabant G, Beck-Peccoz P, Jarzab B, et al.

Thyroid ultrasound need to be carried out to assess medically discovered, noticeable or palpable thyroid blemishes or goitre. It is not indicated for hypothyroidism or hyperthyroidism in the lack of goitre; nor is it showed for globus, non-specific signs, or for screening. Stagnaro-Green A, Abalovich M, Alexander E, et al.
