Galactorrhea hyperprolactinemia is increased blood prolactin levels associated with galactorrhea (abnormal milk secretion). It may be caused by such things as certain medications, pituitary disorders and thyroid disorders. The condition can occur in males as well as females.
The magnitude that prolactin is elevated can be used as an indicator of the etiology of the hyperprolactinemia diagnosis. Prolactin levels over 250 ng/mL may suggest prolactinoma. Prolactin levels less than 100 ng/mL may suggest drug-induced hyperprolactinemia, macroprolactinemia, nonfunctioning pituitary adenomas, or systemic disorders.
A prolactinoma is a tumor of the pituitary gland that produces the hormone prolactin.It is the most common type of functioning pituitary tumor. [1] Symptoms of prolactinoma are due to abnormally high levels of prolactin in the blood (hyperprolactinemia), or due to pressure of the tumor on surrounding brain tissue and/or the optic nerves.
[25] [34] Domperidone acts as a peripheral dopamine antagonist and is hypothesized to stimulate prolactin secretion, with a 2003 study supporting that hypothesis. [ 26 ] A 2018 meta-analysis of five randomized controlled trials found that domperidone resulted in a moderate increase of in breast milk volume for mothers of preterm infants with ...
The most common complex found in blood consists of prolactin and immunoglobulin G (IgG). [1] While the free prolactin hormone is active, prolactin in the macroprolactin complex does not have any biological activity in the body and is considered benign. [2] However, macroprolactin is detected by all Laboratory tests that measure prolactin in ...
Cabergoline, sold under the brand name Dostinex among others, is a dopaminergic medication used in the treatment of high prolactin levels, prolactinomas, Parkinson's disease, and for other indications. [3] It is taken by mouth. Cabergoline is an ergot derivative and a potent dopamine D 2 receptor agonist. [4]
High levels of prolactin in the blood (which may occur as a result of certain tumors or as a side effect of certain medications) has been associated with gynecomastia. [26] A high level of prolactin in the blood can inhibit the release of gonadotropin-releasing hormone and therefore cause secondary hypogonadism.
