Pituitary Disorders in Pregnancy.

Pregnancy is associated with alterations in pituitary hormonal function and enlargement of the pituitary gland. Pituitary dysfunction diagnosis can be challenging during pregnancy due to known alterations in hormonal status. Pituitary disorders are relatively common; with advancements in medical care, more women with pituitary disorders are becoming pregnant. Management includes optimization of hormonal function and close monitoring for signs of tumor progression during pregnancy. Tumor-directed medical therapy is generally discontinued during pregnancy but can be reinitiated if there is evidence of tumor growth. Most women do not show aggressive tumor growth during pregnancy and can be managed conservatively until delivery.
