One common cause of hyperprolactinemia is a growth or tumor on the pituitary gland called a prolactinoma. The tumor produces high levels of prolactin.
More about Treatment
Hyperprolactinemia is a condition in which a person has higher-than-normal levels of the hormone prolactin in the blood. The main function of prolactin is to stimulate breast milk production after childbirth, so high prolactin levels are normal in pregnancy.
A doctor performs a blood test to check prolactin levels. If prolactin levels are high, the doctor will test for other conditions. If they suspect a tumor, they may order an MRI scan to try to determine if a pituitary tumor is present.
