Prolactin, a hormone known as prolactin, is a hormone of the pituitary gland. The prolactin stimulates the growth of the breasts and the production of milk during pregnancy and after childbirth.

Milk hormone is secreted in men in small quantities, and it is secreted in larger quantities in pregnant women and newborn mothers. The production of milk hormone must be appropriate and controlled, as any increase or decrease causes major problems for both sexes.

In this article, we focus on knowing the causes of high milk hormone, and its most important symptoms in women and men.

The doctor determines, based on the result of an analysis, whether the results are normal or not. The results differ slightly from person to person, and sometimes from laboratory to laboratory.

There are constant values ​​that express the natural milk hormone, and they are as follows:

  • Non-pregnant women less than 25 ng/ml.
  • Pregnant women: 34 to 386 ng/ml.
  • Men less than 15 ng/ml. [4]

  • Stimulation and stimulation of the nipple.
  • Having a seizure.
  • A chest injury.

There is also an underlying cause in what is known as, a tumor that affects the pituitary gland, which causes it to become turbulent, and causes it to secrete a greater than normal amount of the milk hormone.

High prolactin is also caused by some health conditions such as:

  • Laziness and lethargy of the thyroid gland.
  • Kidney disease.
  • Especially in the chest area.

Some medications are involved in elevating prolactin, especially medications that affect dopamine. These medications include:

  • Antipsychotics such as: risperidone, haloperidol.

  1. MRI to see in detail the pituitary gland and its surroundings to confirm the presence of a prolactinoma, and to know its exact size and location.
  2. CT scan when MRI is not available, or is not appropriate for the patient’s condition. [2]

Is high prolactin dangerous?

There are no major concerns about the complications of high prolactin, as it mostly comes from a prolactinoma, and therefore the tumor is easy to treat and with it the risks of high milk hormone disappear.

Some warn of the complications of high milk hormone, although it is not life-threatening, but it is still able to infect women with infertility, severely disturbed menstrual cycle, and irregular timing, so it is recommended to quickly treat and not neglect when discovering any change, even a slight change in the levels of the milk hormone.
