You're probably hearing about all the tests you'll need to have since you're expecting a baby, right? Sometimes these things can be a little scary. But once you're properly informed, that fear can be overcome. Today we're going to talk about a non-stress test that many of you have heard of, or that your doctor has told you to do. Let's simply understand what this really is, why it's done, and how it's done.
What is this non-stress test?
Simply put, this is a test that monitors your baby's heartbeat for about 20 to 30 minutes . It looks for changes in the baby's heart rate as the baby moves around inside the womb, and sometimes with the contractions you feel in your belly (we also call these contractions ). It's called 'non-stress' because the baby is not put under any pressure, that is, 'stress', during this test. It's very simple, and it doesn't cause any problems for the baby .
Why is this non-stress test (NST) done?
Now you're probably wondering, 'Why am I being asked to do this?' There could be several reasons.
Usually, a doctor does this (NST) because they want to find out a little more about the baby's health .
- If your pregnancy is high-risk: For example, if you have diabetes, high blood pressure , or have had problems with your baby in previous pregnancies, your doctor may want to take extra care of your baby. In such cases, this test can help confirm that your baby is doing well .
- Post-due date: Sometimes, even though the due date has been set, the baby is late. After a few days, this test is done to see if the baby is still healthy and well inside the womb.
- If other problems arise during pregnancy: for example, you feel that the baby's movements (kicking) are lacking , or if you have any doubts about the baby's development in the womb, you can do this at that time as well.
What exactly does this test look for?
This is mainly to see if your baby is responding normally to stimulation and is getting the right amount of oxygen . Think about it, when your baby is awake and moving around, their heart rate should increase slightly. That's a healthy sign.
Important: Just because your baby doesn't respond well to this test doesn't mean he's definitely in danger. Sometimes, your baby might be asleep , or it might be for some other reason. If that's the case, your doctor will likely order more tests. So don't worry, okay?
Another test that is sometimes done: Biophysical Profile (BPP)
Sometimes, doctors may also do a test called a biophysical profile (BPP) along with the NST . This test combines an ultrasound scan and an NST . It checks the baby's breathing, movement, the amount of fluid around the baby (called amniotic fluid in medical terms), the baby's tone, and the baby's heart rate. This is a more detailed test.
So, do I really need to do this non-stress test (NST)?
This is really up to your doctor or midwife. As mentioned earlier, if you have a high-risk pregnancy , if you have had any complications during your pregnancy, or if you are in the low-risk category but your due date is past, your doctor may recommend this test. They are the ones who know whether this is necessary for your situation or not. So it is best to listen to what your doctor says.
How is this non-stress test (NST) done? What happens?
Okay, now let's see what happens when we do this test. This is very simple, there is no reason to be afraid.
All you have to do is lie on your left side of the bed (this is because the baby gets better blood flow when you lie on your left side). Then, two small devices (monitors) are attached to your abdomen with a strap.
- A single monitor records the baby's heartbeat and movements .
- The other monitor records your uterine contractions (i.e. contractions in your abdomen) .
At this time, a medical technician or nurse sits next to you, watching your baby's heart rate on a screen . Information about your uterine contractions is recorded on a separate sheet of paper. This all happens over a period of about 20 to 30 minutes .
What to do if the baby is sleeping?
Sometimes the baby may be asleep during the test. Since the baby is moving less, you may not see much of a difference in the heart rate. If that happens, the technician may use a trick to wake the baby up. Sometimes they will try to wake the baby up by placing a buzzer on your stomach. Or they may ask you to drink some sugar water or eat something to stimulate the baby. These things are done to see how the baby really responds.
Is this non-stress test (NST) done at any point during pregnancy?
This (NST) test is usually done anytime between 26 and 28 weeks of your pregnancy. That's about 6 1/2 to 7 months. The reason it's done at this time is because the baby's nervous system is well developed by this time . That's when the baby moves, and his heart rate starts to respond appropriately (i.e., speed up or slow down). So, if you do it before this time, it can be difficult to accurately monitor the baby's heart rate.
How long does it take to get results?
This is one of the best things about this test! You can know the results of the (Nonstress Test) immediately after the test is done . You will also have the opportunity to discuss the results with the doctor right there. So you don't have to wait long for the results . Isn't that a great relief?
So, what are the most important things we should remember from what we've said?
Okay, from what we've talked about with the Non-Stress Test (NST), there are a few things you need to keep in mind:
- (NST) is a very simple test that does not cause any pressure or discomfort to the baby. The name itself suggests it, right?
- This checks whether the baby is doing well in the womb and whether the baby is getting the oxygen it needs. Changes in the heart rate are especially monitored when the baby moves.
- This is usually done in high-risk pregnancies, when the baby is due, or if there is any doubt about the baby's health.
- Don't worry if your baby doesn't respond during the test. It doesn't always mean there's a problem with your baby. The doctor will investigate further.
- The results are immediate, so there's no need to worry.
Finally, talk to your doctor or midwife about this. Share any concerns or fears you have with them. They are the ones who can give you the best advice.
Wishing you and your unborn baby all the best!
