One common cause of hyperprolactinemia is a growth or tumor on the pituitary gland called a prolactinoma. The tumor produces high levels of prolactin. These tumors can be large or small and are usually benign, meaning they are not cancerous. Large tumors can also cause headaches, vision problems, or both.
Likewise, what are the symptoms of prolactin levels being high?
In females, prolactinoma can cause:
- Irregular menstrual periods (oligomenorrhea) or no menstrual periods (amenorrhea)
- Milky discharge from the breasts (galactorrhea) when not pregnant or breast-feeding.
- Painful intercourse due to vaginal dryness.
- Acne and excessive body and facial hair growth (hirsutism)
What can cause overproduction of prolactin?
Overproduction of prolactin from a pituitary tumor (prolactinoma) can cause a decrease in normal levels of sex hormones — estrogen in women and testosterone in men. Excessive prolactin in the blood affects men and women differently. In women, prolactinoma might cause: Irregular menstrual periods.
