Hello! You must be very happy and a little curious these days, expecting a new guest. Pregnancy is truly an amazing experience. What a miracle it is to have another life growing inside your body! During this time, we need to take great care of both your health and that of your baby. So, today I am going to talk about a very important hormone that is produced in your body during pregnancy, but which you may not have heard of. That is Human Placental Lactogen, or HPL for short.
What is Human Placental Lactogen?
Simply put, this HPL is a special hormone that is released by the placenta that forms inside your uterus when you become pregnant. Now you may be wondering, "What is this placenta?"
Think of it like a super-supply center for your baby inside the womb. It's attached to your uterine wall, providing your baby with all the oxygen and nutrients it needs. Not only that, but it also removes waste products from your baby's blood. So, a properly functioning placenta is essential for your baby's healthy development.
This HPL hormone has another name, which is Human Chorionic Somatomammotropin (HCS) . Doctors may sometimes use this name as well. This HPL level can be measured with a blood test and can give some idea of whether the placenta is working well and whether the baby is healthy.
What happens with this HPL hormone? Why is it so important?
Scientists are still trying to fully understand the full functions of this HPL hormone, but based on what's been discovered so far, it does some very important things for you and your baby.
1. Preparing for lactation: They believe that this HPL hormone stimulates the milk glands in your breasts, preparing your body to produce milk after the baby is born . Isn't it amazing? How your body prepares for it even before the baby arrives!
2. More nutrition for the baby: This HPL hormone also helps control your body's metabolism . That is, this hormone works in such a way that there are more nutrients needed by the baby in your blood. This is like allocating a special supply for the baby.
3. Reduced insulin sensitivity: Another important thing is that this HPL hormone can make your body less responsive to the hormone insulin . Now look, insulin is a hormone that helps take the sugar in our blood, that is, glucose , into the cells and create energy. When this insulin sensitivity decreases during pregnancy due to HPL, more glucose remains in your blood. Then, that extra glucose can be used for the growth of the baby in the womb. This is also a wonderful plan of nature!
What should the HPL level be like in general?
This HPL level increases gradually throughout pregnancy. That's the normal pattern.
- If you are not pregnant, this level is much lower, around `0.00-0.10 mcg/mL (micrograms per milliliter)`.
- During the first trimester (within the first 3 months), it increases to `0.20-2.10 mcg/mL`.
- In the second trimester (months 4-6), it is around `0.50-6.70 mcg/mL`.
- During the third trimester (months 7-9), this level peaks at `4.50-12.80 mcg/mL`.
- After the baby is born, this HPL level returns to normal, that is, to the level it was before pregnancy.
This HPL hormone can usually be detected in a blood test around 6 weeks into pregnancy. If you are carrying twins, your HPL levels may be slightly higher than normal.
How is the HPL (or HCS) level measured? When should it be checked?
This HPL level is measured with a very simple blood test. The doctor takes a small sample of blood from a vein in your arm and sends it to the lab. That's it.
However, this test is not performed on every pregnant woman. The doctor will only decide to perform this test if there is a special reason. For example:
- If the level of water around the baby, that is , amniotic fluid, appears to be low.
- If something unusual is found during a previous ultrasound .
- If you have high blood pressure (hypertension) during pregnancy.
- If your doctor thinks you are at risk of developing gestational diabetes .
In such a situation, looking at the HPL level can provide additional information about the functioning of the placenta.
What happens if the HPL level is higher than expected?
If your HPL level is higher than expected, don't panic. Your doctor will explain the reason to you. This is because you cannot draw a conclusion based on the HPL level alone. Your doctor will consider many factors, such as your health status, pregnancy history, and other test results.
Sometimes, elevated HPL levels can be caused by:
- If you have diabetes .
- If there is more than one baby in the womb (like twins).
However, the doctor will run more tests if necessary.
What does it mean if the HPL level is lower than expected?
If your HPL level is lower than expected, that's also something to talk about with your doctor. This can sometimes be a sign of a problem. For example:
- There is a possibility of miscarriage .
- Preeclampsia is a condition of high blood pressure that occurs during pregnancy.
- There may be some weakness in the placenta or some problem with the baby's development.
Important: Don't panic if you find out your HPL level is low or high. This is just one test. Your doctor is the best person to analyze this information and advise you.
Is there anything we can do to maintain this HPL level?
To be honest, we can't directly control the levels of hormones like HPL. It's something that happens naturally in the body. However, taking care of certain things before and during pregnancy can reduce the risk of conditions like gestational diabetes and hypertension during pregnancy. These conditions can sometimes indirectly affect HPL levels.
So, what can we do?
- Reduce junk foods , that is, fast foods with artificial flavors and high fat content, as much as possible. Sugary drinks are also not good.
- Eat a balanced diet. Choose good proteins (fish, eggs, milk, nuts), complex carbohydrates (brown rice, beans, vegetables), and good fats (for example, olive oil and avocado instead of fried foods).
- Include a variety of vegetables and fruits in your diet. The more vegetables and fruits you eat, the better.
- Exercise as directed by your doctor. There are many simple exercises, such as walking, that pregnant women can do.
- Try to maintain your healthy weight .
Although these things don't directly affect HPL levels, they are very beneficial for your and your baby's overall health.
What else should I ask the doctor about HPL?
If your doctor tells you to have an HPL blood test, don't be afraid to ask any questions you have. It's important to be well-informed. Here are some questions you can ask:
- "Dr./Ms., why did you recommend that I have this HPL test? "
- "Do I need to do anything special before this test? For example, do I need to fast ?"
- " When will I get the report for this test? "
- "If my HPL level is low (or high), what could be the cause? "
- "Am I at risk of developing gestational diabetes or high blood pressure ?"
- " Did you also measure other hormones with this blood test? If so, what do the results say?"
- " Will I need to have any further tests, such as an ultrasound scan? "
By asking these questions, you can gain a better understanding of the situation.
Finally, things to remember (Take-Home Message)
Okay, so from what we've talked about, I hope you've got a good idea about the HPL hormone.
Simply put, HPL is a hormone produced by the placenta during pregnancy that is very important for both you and your baby.
These hormone levels can be measured with a blood test. The results can give you some indication of the health of you, your placenta, and your baby. But remember, this is not the only criterion. Your doctor will take all of this into account and give you the best advice.
Therefore, work closely with your doctor throughout your pregnancy. Ask and answer all your questions and doubts. Then you can spend this beautiful time happily and healthily. Best wishes to you and your little one in your womb!
