Synopsis
What Do You Mean By Hyperprolactinemia?
Hyperprolactinemia refers to an abnormally elevated level of prolactin within the bloodstream. For women who are not pregnant or breastfeeding, a prolactin level greater than 25 nanograms per milliliter (ng/mL) signifies an abnormal elevation.
Causes Of Hyperprolactinemia
A high prolactin level may occur due to physiological, pathological, or medication-related causes.
- Pituitary Tumors: Also known as a prolactinoma, these are the most common pathological cause of elevated prolactin levels, and they are usually benign (non-cancerous) but can vary in size from small (microadenoma) to large (macroadenoma).
- Medications: Medications that interfere with the hormone dopamine, which inhibits the secretion of prolactin, can also elevate prolactin levels.
- Hypothyroidism: When thyroid hormone levels are reduced, there is an increased release of thyrotropin-releasing hormone (TRH), which causes an increase in the amount of prolactin.
- Polycystic ovarian syndrome (PCOS): Women with PCOS can have mildly elevated prolactin levels as a result of hormonal irregularities.
- Lifestyle Factors: Chronic stress, lack of physical activity, inadequate sleep, and stimulation of the nerve receptors in the breasts and chest can all result in abnormally high prolactin levels.
- Chest wall injury or surgery: Trauma, burns, or surgery to the chest can stimulate the nerve receptors and cause prolactin levels to be increased.
An increase in prolactin may occur due to decreased clearance from the body.
Symptoms Of Hyperprolactinemia
High prolactin levels (hyperprolactinemia) in women can present with various symptoms. Some of the more common symptoms of hyperprolactinemia in women are:
- Hyperprolactinemia can cause abnormal menstrual cycles or no menstrual cycles (amenorrhea).
- Increased prolactin levels may prevent ovulation, thereby making it difficult for the woman to become pregnant.
- Increased prolactin levels in women who are not pregnant can lead to galactorrhea, which is the production of breast milk without pregnancy.
- Increased prolactin levels can decrease a woman's libido.
- Increased prolactin levels can affect vaginal lubrication and cause pain during sexual intercourse.
- Increased prolactin levels may be associated with headaches or visual changes.
- Increased prolactin levels may affect hormones, leading to acne or excess hair on the face and body.
- Changes in hormone levels, including increased prolactin levels, can affect a woman's mood and cause depression.
Diagnosis Of High Prolactin Levels
Diagnosis typically begins with a blood test measuring prolactin levels.
A second test may be performed if the first test result shows a mildly elevated level. If there are persistently elevated prolactin levels, the physician may perform additional testing, including but not limited to:
- MRI scans to identify the presence of pituitary tumors.
- Thyroid function tests to rule out hypothyroidism as a cause of elevated prolactin levels.
- Laboratory evaluation of hormones to assess overall reproductive health.
Treatment Options For High Prolactin Levels In Non-Pregnant Women
If you are not pregnant and are experiencing high levels of prolactin, you will be happy to know that there are treatment options available for you. Here are the treatment options:
- Dopamine agonists: The first treatment option is the use of dopamine agonists that may help to increase dopamine levels in the body to decrease the production of prolactin and reduce the size of tumours in the pituitary gland.
- Transsphenoidal surgery or radiation: For women who have very large tumours or tumours that do not respond to the medications, the surgery called transsphenoidal surgery might be necessary. In addition, radiotherapy may be a required form of treatment.
- Lifestyle modifications and supportive care: It is important to consider stress reduction, physical activity, and medication review to check which medications increase prolactin levels. Most women will respond well to medical treatment. It usually takes weeks to months for the prolactin level to return to a normal level.
Conclusion
Elevated prolactin levels in females who are not pregnant can have a major effect on menstrual health, fertility, and overall hormonal environment. The first step in effective treatment is identifying the underlying cause (whether it is related to the pituitary gland, an illness, a medication that might be causing it, or an aspect of lifestyle). The majority of women will respond well to both medical and lifestyle changes, leading to normalisation of prolactin levels.
Frequently Asked Questions
Do high levels of prolactin affect fertility?
Elevated levels of prolactin (hyperprolactinemia) disrupt the normal menstrual cycle and inhibit ovulation; hence, women with high prolactin levels are at risk for infertility.
Is it possible to become pregnant if prolactin levels are high?
If prolactin levels are treated effectively, many women will conceive without future medical treatment.
Are women required to take medication for hyperprolactinemia for their entire life?
Not necessarily; some patients can terminate medical treatment at the direction of their physician once their prolactin levels stabilize.
Is hyperprolactinemia a serious health issue?
Untreated hyperprolactinemia, though not usually a life-threatening condition, may lead to infertility, decreased bone mineral density, or potentially impair vision if a tumor is present.
Can stress cause high levels of prolactin?
Stress can cause a temporary mild increase in prolactin levels, but persistently high values of prolactin indicate another cause.
