Hyperprolactinemia is a condition characterized by excess prolactin, the hormone responsible for milk production in a woman’s breasts.
What is most common cause of hyperprolactinemia?
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.
What happens when your prolactin levels are high?
Excess prolactin can cause the production of breast milk in men and in women who are not pregnant or breastfeeding. In women, too much prolactin can also cause menstrual problems and infertility (the inability to get pregnant). In men, it can lead to lower sex drive and erectile dysfunction (ED).
What causes high prolactin in a woman?
Its hormones help regulate important functions such as growth, metabolism, blood pressure and reproduction. Other possible causes of prolactin overproduction include medications, other types of pituitary tumors, an underactive thyroid gland, ongoing irritation to the chest, pregnancy and breast-feeding.Does hyperprolactinemia go away?
Sometimes there’s no specific cause for your high prolactin levels. This is known as idiopathic hyperprolactinemia. It usually goes away without treatment after several months. If your prolactin levels do not go down, your doctor will likely prescribe medication.
What medication can be used to help treat hyperprolactinemia?
Medical treatment of hyperprolactinemia is based upon use of dopamine agonists (DA): bromocriptine, lisuride, quinagolide and cabergoline. In over 80% of cases, these drugs induce normal prolactinemia and ovulatory cycles. In resistant cases, the DA should be changed.
Can hyperprolactinemia cause weight gain?
Hyperprolactinemia in men can cause suppression of testosterone release, resulting in diminished libido. Even in men, breast enlargement (gynecomastia) and breast discharge can occur. High levels of prolactin can also result in weight gain and neuropsychological disturbances.
Does hyperprolactinemia cause breast pain?
Symptoms from the high prolactin levels include discharge of milk from the breast (galactorrhoea) and breast tenderness. These symptoms are more common in women than men. High prolactin levels can also affect the function of the ovaries or testes by interfering with the hormones that control these glands.Can hyperprolactinemia cause tiredness?
Rarely, the prolactinoma may press on the rest of the pituitary gland, stopping it from producing other hormones. This can cause symptoms such as tiredness, fainting, low blood pressure, low blood sugar or collapse.
Can I get pregnant with high prolactin?High prolactin levels inhibit secretion of FSH, which is the hormone that triggers ovulation. So, if your prolactin levels are high, your ovulation may be suppressed. This is why women who are breastfeeding (and thus have high levels of prolactin) usually don’t become pregnant.
Article first time published onCan stress cause high prolactin levels?
Regardless of what the research says, stress does cause physiological changes within the body. It boosts adrenaline and cortisol. These stress hormones, in turn, inhibit the release of gonadotropin-releasing hormone (GnRH). Stress also increases prolactin production.
How common is hyperprolactinemia?
The prevalence of hyperprolactinemia ranges from 0.4% in an unselected adult population to a 5% incidence among women of reproductive age. In postmortem studies, pituitary microadenomas have been found in 1.5%-26.7% of autopsies.
Does hyperprolactinemia cause acne?
Pituitary hormones Prolactin: prolactin receptors are well expressed in the adrenal glands. In cases of hyperprolactinemia, adrenal androgens are secreted in an increased manner and contribute to the rapid formation of acne pimples.
Does High prolactin levels cause depression?
The causes of the association of hyperprolactinemia and depression are not known, but it appears that excessive prolactin secretion (with low or normal levels of estrogens) may cause depressive symptoms.
When should hyperprolactinemia be treated?
There are two principal reasons why patients with hyperprolactinemia may need to be treated: existing or impending neurologic symptoms due to the large size of a lactotroph adenoma, and hypogonadism or other symptoms due to hyperprolactinemia, such as galactorrhea [1-3].
What foods reduce prolactin levels?
Foods that lower prolactin levels are generally high in zinc; think shellfish, beef, turkey and beans. It’s also important to get plenty of B6, so foods like potatoes, bananas, wild salmon, chicken and spinach can help boost those vitamin levels.
Can Prolactinoma cause death?
Mortality is unlikely, although a study by Soto-Pedre et al (discussed below) did report increased mortality depending on the cause of hyperprolactinemia. In cases where the condition is due to a large prolactin-secreting tumor, local mass effect can lead to significant morbidity.
How long does it take to reduce prolactin levels?
Prolactin levels usually fall within the first two to three weeks of treatment, but detectable decreases in adenoma size take more time, usually several weeks to months.
Does hyperprolactinemia cause hair loss?
The types of hair loss described with hyperprolactinemia are mainly from the androgenetic or diffuse type and connected with hormonal abnormalities, especially the androgens.
How do you test for hyperprolactinemia?
Doctors detect excess prolactin with a blood test that measures the prolactin level. Most often, a single blood test is all that is needed. For most patients, a level below 25 μg/L (micrograms per liter) is normal, and above 25 is too high. A prolactin level above 250 μg/L most often indicates a prolactinoma.
Which drugs cause hyperprolactinemia?

Can high prolactin cause miscarriage?
Since hyperprolactinemia may contribute to miscarriages, some doctors check a woman’s prolactin level and give medication to lower the level if it is elevated. In the case of recurrent miscarriages and prolactin, one older study found elevated prolactin levels in women who had two or pregnancy losses.
Does prolactin affect mood?

Does prolactin affect sleep?
Prolactin (PRL) is one of the growth factors that influences sleep. It is unique as a growth-sleep factor in that its primary action is to promote rapid eye movement sleep (REMS; also called paradoxical sleep).
