Is your menstrual cycle irregular? Or do you have a milky discharge from your breasts when you are not breastfeeding? Your doctor may have asked you to take a blood test to check for a hormone called Prolactin. So don't be scared when you hear this name. Many people have questions about this. Today, we will talk about everything very simply about this Prolactin test .
What exactly is this hormone called Prolactin?
Simply put, Prolactin is a hormone in our body. It is produced by a pea-sized gland located just below our brain. We call this the pituitary gland .
This hormone is often discussed in connection with pregnancy and childbirth. This is because, for a pregnant mother and a new mother who has given birth, this hormone Prolactin is essential for producing the milk needed for the baby. Its levels naturally increase during that time.
However, even if you are not pregnant, anyone can have elevated levels of Prolactin in their body. Both women and men need this hormone in small amounts for various processes in the body.
How does this hormone work in the body?
The hormone prolactin, along with two other hormones , estrogen and progesterone , helps to stimulate the milk-producing glands in the breasts. When a baby is born, when the baby sucks on the mother's breast, a signal is sent to the brain, which increases the production of prolactin. This is what keeps the milk supply going.
Imagine, if you decide not to breastfeed after having a baby, within about two weeks your prolactin levels will drop back to the normal levels they were before pregnancy.
What are the common causes of high prolactin levels?
Our prolactin levels fluctuate throughout the day, and even the most ordinary things we do can affect it.
- Eating: After a well-filled meal.
- Exercising: When you exercise hard.
- Stress: When you are under extreme stress .
- Having sex:
- Breast stimulation:
- Bodily injuries or minor accidents:
- Conditions such as seizures:
It's normal for prolactin levels to temporarily increase due to things like this. That's why doctors sometimes recommend fasting for a few hours before this test.
What are normal levels of prolactin?
Prolactin levels in the blood are usually reported in nanograms per milliliter (ng/mL). These values may vary slightly between labs, but here are some generally accepted normal ranges:
| Person | Normal Prolactin Level (ng/mL) |
|---|---|
| Male individuals | Less than 20 ng/mL |
| Non-pregnant women | Less than 25 ng/mL |
| Pregnant women | Between 80 and 400 (80-400 ng/mL) |
The most important thing is, don't worry if your lab results are slightly out of the normal range. Only your doctor can explain what it really means.
What happens if prolactin levels are elevated (Hyperprolactinemia)?
Elevated prolactin levels are medically known as hyperprolactinemia. This can cause irregular or absent menstrual cycles in women, and can even lead to infertility.
Sometimes, if your prolactin levels are abnormally high, about 1,000 times the normal high , it could be due to a small tumor in the pituitary gland. This is called a prolactinoma. It is not cancer. These can usually be treated with medication. In such cases, your doctor will order an MRI scan of your brain. This can show exactly if the tumor is there and how big it is.
Other causes of elevated prolactin
- Diseases of the part of the brain that controls the pituitary gland (the hypothalamus).
- Eating disorders such as anorexia.
- Certain medications: Some medications for depression, high blood pressure, nausea, strong painkillers, and birth control pills.
- Injuries or infections to the chest area: Conditions such as chest surgery scars, herpes ``(Shingles)``.
- Other medical conditions: Kidney disease, hypothyroidism, and Polycystic Ovarian Syndrome (PCOS), a hormonal imbalance related to the ovaries.

What if prolactin levels decrease?
Lower than normal levels of prolactin may be due to a condition called ``Hypopituitarism.'' This means that the pituitary gland does not produce enough hormones.
But in most cases, low prolactin levels do not require medical treatment. The main problem that this causes is difficulty breastfeeding after having a baby.
Some studies have found that women with prolactin levels below 5 ng/mL may have a slightly increased risk of developing metabolic syndrome, a condition that can lead to heart disease and diabetes later in life. Certain medications, such as dopamine, can also lower prolactin levels.
Prolactin testing and treatment
This is a very simple blood test. The lab will just take a small sample of blood from a vein in your arm. You may feel a little pain when the needle is inserted. This is normal. You can get the results in a few days.
Treatment depends on the cause of your high prolactin levels. If the cause is a small tumor (prolactinoma), your doctor will prescribe medication to shrink the tumor and lower your prolactin levels. Sometimes, no treatment is needed.
Also, the doctor may advise you to make some lifestyle changes.
- Reducing stress through things like meditation.
- Avoid wearing clothes that constrict the chest.
- Taking supplements such as vitamin B6 or vitamin E as directed by a doctor.
Take-Home Message
- Prolactin is a normal hormone found in the bodies of both men and women. It is often discussed in connection with breastfeeding.
- Don't be alarmed if your prolactin levels are slightly out of the normal range on your lab report. It could be due to stress or something you ate.
- Elevated prolactin levels can cause menstrual cycle problems and infertility, but there are effective treatments for this.
- Very high prolactin levels can be caused by a non-cancerous tumor (prolactinoma). These can also usually be treated with medication.
- If you have any questions or concerns about this, the best person to talk to is your doctor. Do not self-diagnose by searching for information on the internet.
