I am pregnant. . before pregnancy my prolactin level was 800 i ate medicine but still it does not control and nw its 2470...is this dangerous. .

Neurosurgery?: Did you have an MRI to look for a pituitary adenoma prior to pregnancy? Are you having vision changes or headaches? Adenomas can grow during pregnancy and your level is very high. Normal is around 35 to 600 ng/ml . I am sorry the medication isn't working well for you. You may need surgery. http://www.uptodate.com/contents/high-prolactin-levels-and-prolactinomas-beyond-the-basics

Pituitary gland : During pregnancy, prolactin levels increase by 10 to 20 times. After the baby is born, prolactin stays high if you are breast-feeding. In women who do not breast-feed, prolactin levels return to normal soon after they give birth. If you already have a problem before getting pregnant, you may need to be seen by a specialist called Endocrinologist to help monitor your levels throughout the pregnancy
