Endocrine Condition Therefore, high prolactin causes low estrogen in women and low testosterone in men and decreases fertility in both women and men. Low estrogen and testosterone also can result in bone loss and osteoporosis. A blood test is used to detect excess prolactin.
Dopamine: This is a hormone produced by the adrenal glands that slows down prolactin production. Thyrotropin-releasing hormone (TRH): This is a hormone produced by the hypothalamus which increases prolactin production. 1.
High prolactin levels interfere with the normal production of other hormones, such as estrogen and progesterone. This can change or stop ovulation (the release of an egg from the ovary). It can also lead to irregular or missed periods. Some women have high prolactin levels without any symptoms.
If prolactin levels are higher than normal, it often means there is a type of tumor of the pituitary gland, known as a prolactinoma. This tumor makes the gland produce too much prolactin. Excess prolactin can cause the production of breast milk in men and in women who are not pregnant or breastfeeding.
Women with the mildest cases involving high prolactin levels may ovulate regularly but not produce enough of the hormone progesterone after ovulation. This is known as a luteal phase defect.
Therefore, high prolactin causes low estrogen in women and low testosterone in men and decreases fertility in both women and men. Low estrogen and testosterone also can result in bone loss and osteoporosis. A blood test is used to detect excess prolactin.
Other causes of high prolactin include high doses of female sex hormones (estrogens) and underactivity of the thyroid gland (hypothyroidism).
Avoid Gluten
Wheat, rye, and barley are all high in gluten, which may cause an inflammatory response in the body when consumed. This could increase the prolactin level and disrupt dopamine production in the hypothalamus. Thus, avoiding gluten could prove to be an effective way to lower prolactin levels.
Also vitamin D deficiency in prolactinoma patients associated with larger adenoma size and higher prolactin level.
If you experience symptoms of excess prolactin levels (hyperprolactinemia), such as irregular periods and/or loss of interest in sex, contact your healthcare provider. They can order a simple blood test to check your prolactin levels. Prolactin is an important hormone for pregnancy and chestfeeding.
Oestrogen is another key regulator of prolactin and has been shown to increase the production and release of prolactin from the pituitary gland. Studies have shown small increases in prolactin in the blood circulation of women during stages of their reproductive cycle where oestrogen levels are at their highest.
All findings have demonstrated that the manifestation of progesterone effect on mammary glands is dependent upon prolactin and that the role of prolactin is both direct on the glands and indirect through its luteotropic effect - through its stimulation of ovarian progesterone secretion.
Oral medications known as dopamine agonists are generally used to treat a prolactinoma. These drugs mimic the effects of dopamine — the brain chemical that controls how much prolactin is made. Dopamine agonists can decrease the production of prolactin and shrink the size of the tumor.
According to the studies, the rise in serum prolactin levels can result in a reduction of ovarian follicles as well as ovulation(3). Hyperprolactinemia is a common endocrine problem and may be detected in both women and men of all ages depending on the study population(4).
High levels of prolactin can also result in weight gain and neuropsychological disturbances. The size of the tumor correlates with the amount of prolactin secreted. Larger tumors can cause mass effects by compression of local structures.
Prolactinomas produce prolactin, which can lead to high levels of this hormone in the body. There is no known cause for prolactinomas, but genetics may play a part in some cases.
Overall, the results suggest that prolactin is associated with specific psychological symptoms including somatization, anxiety, hostility, paranoid ideation and psychoticism, especially in females, rather than a general indication of depressive symptom severity, and may represent a transdiagnostic hormonal phenotype.
Low magnesium and slightly increased (5x) magnesium (4.1 mM) did not influence prolactin secretion in either 1.8 mM or low calcium, but 10 and 20 mM magnesium inhibited secretion by 50 and 70%, respectively. Inhibition of prolactin secretion by high magnesium was reversible.
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.
During prolonged sustained exercise, the prolactin response is proportional to the intensity at which the exercise is performed, and there is a plateau in the level observed. However, extending the duration of the exercise session can result in a graduate increase in the magnitude of the prolactin response [23,24].
We can also detect other pituitary hormonal changes. A normal prolactin level is less than 20 nanograms per milliliter. A prolactin level of more than 150-200 nanograms per milliliter usually signals a prolactinoma.
Our results show that prolactin levels decrease significantly during the second year of the menopause. Neither combined estrogen/androgen, nor salmon calcitonin therapy had any effect on serum prolactin concentrations in postmenopausal women.
Hyperprolactinemia means you have higher-than-normal levels of prolactin in your blood. The most common cause is a prolactinoma, a benign (noncancerous) tumor in your pituitary gland. Certain health conditions and medications can also cause hyperprolactinemia.
