What is it?

Hyperprolactinemia refers to excess secretion of the hormone prolactin, which is secreted from the pituitary gland and helps stimulate and maintain breast milk production. High levels of prolactin are normal in pregnancy or while breastfeeding. Hyperprolactinemia may be caused due to pituitary tumors, which are typically benign, certain medication, Cushing syndrome, infection or trauma to the hypothalamus, and cirrhosis of the liver.
