Hyperprolactinemia is a disorder marked by the over production of prolactin produced by the pituitary gland. Prolactin is a hormone that stimulates milk production in women. Prolactin normally circulates in the blood in small amounts in non-pregnant women, but if there are high levels in these women it can be a signal of a pituitary tumour and cause problems with your fertility.
Symptoms of Hyperolactinemia
Hyperprolactinemia can cause irregular or no ovulation, excess facial hair and pain during intercourse. Women who have this disorder often have irregular periods, and may also experience galactorrhea—milk production when not pregnant.
Cause of Hyperolactinemia
The most common cause of hyperprolactinemia is a benign tumour growing on the pituitary gland—the gland that produces prolactin. The pituitary gland is located in the base of the brain near the vision center. Other causes of excess prolactin production may be an underactive thyroid (hypothyroidism) or certain medications you may be taking.
