'''Galactorrhea hyperprolactinemia''' is increased blood [[prolactin]] levels associated with [[galactorrhea]] (abnormal milk secretion). It may be caused by such things as certain [[medication]]s, [[pituitary disorder]]s and [[thyroid]] disorders. The condition can occur in males as well as females. Relatively common etiologies include [[prolactinoma]], medication effect, [[kidney failure]], [[granulomatous disease]]s of the [[pituitary gland]], and disorders which interfere with the hypothalamic inhibition of prolactin release. [[Ectopic expression|Ectopic]] (non-pituitary) production of prolactin may also occur. Galactorrhea hyperprolactinemia is listed as a “[[rare disease]]” by the [[Office of Rare Diseases]] of the [[National Institutes of Health]]. This means that it affects less than 200,000 people in the [[United States]] population.<ref name="wrongdiagnosis1">{{cite web|url=http://www.wrongdiagnosis.com/g/galactorrhoea_hyperprolactinaemia/basics.htm |title=What is Galactorrhoea-Hyperprolactinaemia? - RightDiagnosis.com |publisher=Wrongdiagnosis.com |date=2015-04-17 |accessdate=2015-07-09}}</ref>
'''Galactorrhea hyperprolactinemia''' is a condition characterized by abnormal milk secretion ([[galactorrhea]]) and elevated blood levels of prolactin ([[hyperprolactinemia]]). It can occur in both men and women and may be associated with various underlying medical conditions, including pituitary tumors, hormonal imbalances, and medication side effects.
 
The disorder is commonly linked to prolactinomas, which are benign [[pituitary adenoma|pituitary tumors]] that secrete excess prolactin, leading to menstrual irregularities, infertility, and reduced libido. It may also occur due to conditions that disrupt the normal regulation of prolactin release, such as hypothyroidism, stress, kidney failure, and certain medications.
 
== Signs and Symptoms ==
Individuals with galactorrhea hyperprolactinemia may experience the following symptoms:
* Abnormal lactation ([[Galactorrhea]]) in non-pregnant or non-breastfeeding individuals
* Menstrual disturbances including [[amenorrhea]] (absence of menstruation) or irregular periods
* Infertility due to disrupted ovulation in women and impaired sperm production in men
* Decreased libido and sexual dysfunction
* Erectile dysfunction in males
* Headaches and visual disturbances (in cases of large pituitary tumors)
* Bone loss ([[osteoporosis]]) due to prolonged hormonal imbalance
 
== Causes ==
Galactorrhea hyperprolactinemia can result from various causes, including:
 
=== Pituitary and Hypothalamic Disorders ===
* [[Prolactinoma]] – A benign tumor of the pituitary gland that secretes excessive prolactin.
* [[Granulomatous disease]]s affecting the pituitary gland.
* [[Hypothalamic dysfunction]] – Disrupts the normal inhibition of prolactin release.
 
=== Hormonal Disorders ===
* [[Hypothyroidism]] – Low levels of thyroid hormone can trigger increased prolactin secretion.
* [[Polycystic ovary syndrome]] (PCOS) – Can be associated with mild hyperprolactinemia.
 
=== Medication-Induced Hyperprolactinemia ===
Certain medications can increase prolactin levels by blocking dopamine, which normally inhibits prolactin release:
* Antipsychotics (e.g., [[Risperidone]], [[Haloperidol]])
* Antidepressants (e.g., [[SSRIs]], [[tricyclic antidepressants]])
* Dopamine antagonists (e.g., [[Metoclopramide]], [[Domperidone]])
* Opioids and estrogen-containing contraceptives
 
=== Other Causes ===
* Pregnancy and breastfeeding
* Severe stress (physical or emotional)
* Chronic kidney failure
* Liver cirrhosis
* Ectopic prolactin production (rare)
 
== Diagnosis ==
To diagnose galactorrhea hyperprolactinemia, healthcare providers use a combination of clinical evaluation, laboratory tests, and imaging studies.
 
=== Laboratory Tests ===
* Serum prolactin levels – Elevated levels confirm hyperprolactinemia.
* Thyroid function tests (TSH, T3, T4) – To rule out hypothyroidism.
* Serum estrogen and testosterone levels – Assess hormonal balance.

==Signs and symptoms==
== Treatment ==
Symptoms of galactorrhea hyperprolactinemia include a high blood prolactin level, abnormal milk production in the [[breast]], galactorrhea, [[Menstruation|menstrual]] abnormalities, reduced [[libido]], reduced [[fertility]], [[puberty]] problems, and [[headache]]s.<ref name="wrongdiagnosis1"/>
Treatment of galactorrhea hyperprolactinemia depends on the underlying cause.
==Causes==
The following are some of the possible medical causes of galactorrhea hyperprolactinemia that are listed by the [[Diseases Database]]: pregnancy, [[breastfeeding]], [[sexual intercourse]], [[shingles]], prolactin secreting [[pituitary tumor]], along with many others.<ref name="wrongdiagnosis1"/>


==Diagnosis==
=== Medications ===
Galactorrhea is generally considered a [[symptom]] which may indicate a more serious problem. Collection of a thorough [[medical history]], including [[Pregnancy|pregnancies]], surgeries, and consumption of [[drug]]s and medications is a first step in diagnosing the cause of galactorrhea. A [[physical examination]], along with a [[breast examination]], will usually be conducted. [[Blood]] and [[urine]] samples may be taken to determine levels of various [[hormone]]s in the body, including prolactin and compounds related to thyroid function. A [[mammogram]] (an [[X-ray]] of the breast) or an [[ultrasound scan]] (using high frequency sound waves) might be used to determine if there are any [[tumor]]s or [[cyst]]s present in the breasts themselves. If a tumor of the pituitary gland is suspected, a [[magnetic resonance imaging]] (MRI) scan can locate tumors or abnormalities in tissues.<ref>{{cite web |url=http://www.pregnancy.org/question/what-galactorrhea |title=What is Galactorrhea? |publisher=Pregnancy.org |date= |accessdate=2015-07-09 |archive-url=https://web.archive.org/web/20150710161908/http://www.pregnancy.org/question/what-galactorrhea |archive-date=2015-07-10 |url-status=dead }}</ref>
* [[Dopamine agonists]] (first-line treatment for prolactinomas):
* [[Cabergoline]] – More effective with fewer side effects.
* [[Bromocriptine]] – Used in pregnancy when necessary.
* Estrogen replacement therapy – For women with severe hypogonadism due to hyperprolactinemia.
* Thyroid hormone replacement – If hyperprolactinemia is due to hypothyroidism.


==Treatment==
=== Surgery ===
===Medical care===
* Transsphenoidal pituitary surgery – Indicated for large tumors that do not respond to medication or cause vision loss.
Direct treatment is geared toward resolving hyperprolactinemic symptoms or reducing tumor size. Patients on medications that cause [[hyperprolactinaemia]] should have them withdrawn if possible. Patients with [[hypothyroidism]] should be given thyroid [[hormone replacement therapy]]. When symptoms are present, [[medical therapy]] is the treatment of choice. Patients with hyperprolactinemia and no symptoms (idiopathic or microprolactinoma) can be monitored without treatment. Consider treatment for women with [[amenorrhea]]. In addition, [[dual energy X-ray absorptiometry]] scanning should be considered to evaluate [[bone density]]. The persistent [[hypogonadism]] associated with hyperprolactinemia can lead to [[osteoporosis]]. Treatment significantly improves the patient's quality of life. If the goal is to treat hypogonadism only, patients with [[idiopathic]] hyperprolactinemia or [[microadenoma]] can be treated with [[estrogen replacement therapy]] and prolactin levels can be monitored. [[Radiation treatment]] is another option. However, the risk of [[hypopituitarism]] makes this a poor choice. It may be necessary for rapidly growing tumors, but its benefits in routine treatment have not been shown to outweigh the risks.{{citation needed|date=August 2020}}
* Craniotomy – Used in rare cases for aggressive tumors.


===Surgical care===
=== Radiation Therapy ===
General indications for pituitary surgery include patient [[drug intolerance]], tumors resistant to medical therapy, patients who have persistent [[visual field]] defects in spite of medical treatment, and patients with large cystic or hemorrhagic tumors.{{citation needed|date=August 2020}}
* Considered for large, non-resectable tumors or tumors resistant to medication.


===Consultations===
== Prognosis ==
Physicians who are comfortable with the initial evaluation of a patient (without evidence of tumor [[Mass effect (medicine)|mass effect]]) can easily initiate therapy and provide follow-up. However, given the time constraints of modern [[ambulatory medicine]], consultation with an [[endocrinologist]] is often necessary.<ref>{{EMedicine|article|121784|Hyperprolactinemia|treatment}}</ref>
The prognosis for galactorrhea hyperprolactinemia is generally good, especially when diagnosed early. Most patients respond well to dopamine agonists, with normalization of prolactin levels and resolution of symptoms. However, untreated or large prolactinomas may lead to:
==Prognosis==
* Permanent infertility
The prognosis for patients with prolactinomas is good: most remain stable or regress. In pregnant women, prolactinomas must be observed closely because the lesions may greatly increase in size.<ref>{{cite journal|url=http://www.aafp.org/afp/2001/0501/p1763.html |title=Evaluation and Treatment of Galactorrhea  |journal=American Family Physician |volume=63 |issue=9 |pages=1763–70 |date=2001-05-01 |accessdate=2015-07-09|last1=Rosenfeld |first1=Jo Ann |last2=Pena |first2=Kristin S. |pmid=11352287 }}</ref>
* Severe osteoporosis
* Compression of the optic chiasm, leading to blindness
* Pituitary failure (panhypopituitarism)


==Epidemiology==
== Epidemiology ==
Hyperprolactinemia occurs more commonly in women. The prevalence of hyperprolactinemia ranges from 0.4% in an unselected normal adult population (10,000 normal [[Japan]]ese adults working at a single factory) to as high as 9 to 17% in women with [[reproductive disorder]]s. Its prevalence was found to be 5% in a [[family planning clinic]] population, 9% in a population of women with adult-onset amenorrhea, and 17% among women with [[polycystic ovary syndrome]].<ref>{{cite web|url=http://www.medscape.com/viewarticle/447780_2 |title=Hyperprolactinemia: Etiology, Diagnosis, and Management |publisher=Medscape.com |date= |accessdate=2015-07-09}}</ref>
* More common in women, especially those of reproductive age.
* Prevalence: Approximately 0.4% in the general population, but up to 9-17% in women with reproductive disorders.
* Rare in men, but often diagnosed late due to subtle symptoms.

== Summary ==
Galactorrhea hyperprolactinemia is a hormonal disorder characterized by abnormal milk secretion and elevated prolactin levels. It may result from pituitary tumors, medication use, or hormonal imbalances. The condition can cause menstrual irregularities, infertility, and bone loss if untreated. Diagnosis involves hormone tests and imaging, while treatment options include dopamine agonists, hormone therapy, or surgery in severe cases. With appropriate treatment, most patients can recover normal prolactin levels and fertility.

Galactorrhea hyperprolactinemia is a condition characterized by abnormal milk secretion (galactorrhea) and elevated blood levels of prolactin (hyperprolactinemia). It can occur in both men and women and may be associated with various underlying medical conditions, including pituitary tumors, hormonal imbalances, and medication side effects.

The disorder is commonly linked to prolactinomas, which are benign pituitary tumors that secrete excess prolactin, leading to menstrual irregularities, infertility, and reduced libido. It may also occur due to conditions that disrupt the normal regulation of prolactin release, such as hypothyroidism, stress, kidney failure, and certain medications.

Signs and Symptoms[edit]

Individuals with galactorrhea hyperprolactinemia may experience the following symptoms:

  • Abnormal lactation (Galactorrhea) in non-pregnant or non-breastfeeding individuals
  • Menstrual disturbances including amenorrhea (absence of menstruation) or irregular periods
  • Infertility due to disrupted ovulation in women and impaired sperm production in men
  • Decreased libido and sexual dysfunction
  • Erectile dysfunction in males
  • Headaches and visual disturbances (in cases of large pituitary tumors)
