38 Weeks Pregnant Baby Gets Hiccups All the Time
Some healthcare superstitions may exist rooted in truth. Only most of these hand-me-downwards stories are myths that persist, despite being repeatedly proven invalid, causing undue stress for expecting parents.
One such myth is that a baby with hiccups in the womb may indicate potential danger in utero.
Concerns over fetal hiccups may be based on old creature studies. According to one researcher's 2012 article in BMC Pregnancy and Childbirth, information technology's suggested that hiccups in utero might exist caused by pinch of the umbilical cord. His possible explanation is that hiccupping might make a fetus move away from the cord, which would relieve the compression and return blood flow to normal.
However, I couldn't observe the study, which involved fetal sheep, that he quoted.
Much like the "vaccines crusade autism" lie, which has been perpetuated since a at present-discredited study in the late 1990s, people grabbed onto the thought that fetal hiccups could cause problems similar preterm nascence or stillbirth – none of which has ever been scientifically studied in human fetuses.
I can understand why patients might be worried about hiccups. It looks foreign on ultrasound to see your baby jerking around in the womb. It's simply natural to Google the phenomenon, just to discover article after article suggesting that your pregnancy may be at run a risk.
Fetal hiccups are normal. Having hiccups does non mean something is wrong with your babe, and you lot don't need to endeavor to become rid of the condition. Let's wait at the information to testify it and discuss what's really going on in your abdomen with every hic, hic, hiccup.
What happens during fetal hiccups?
In the fetus, the diaphragm acts similarly to how it will when the babe is born. The diaphragm controls animate, which is a rhythmic, intermittent move. The fetus isn't breathing air, but amniotic fluid – the liquid that surrounds the fetus during pregnancy.
With each inhalation, the diaphragm – a muscle below the lungs – moves down. This causes a downwardly and outward displacement of the abdomen. Instead of the chest rising and falling with breaths like an adult's would, fetuses and babies tend to involve their bellies more. This gentle movement is undetectable by the meaning patient.
Hiccups follow that same, rhythmic movement as animate, only more forcefully. The unabridged fetal trunk moves in a jerking motion with each hiccup, which many meaning patients tin feel. Just similar in babies and adults, fetal hiccups occur for a short, consistent period of time, then go away on their own.
A closer look at fetal hiccups
Ultrasounds show normal fetal breathing and fetal hiccups, which are not a danger to the fetus or the pregnancy.
What does the science say?
There are several problems with the study that suggests hiccups are associated with potentially dangerous umbilical string compression. The researcher speculates that hiccups are a hyper-reactive response to reduce claret period from a knotted or compressed umbilical string.
Umbilical string issues are e'er high on our radar. Patients worry about this, and nosotros are e'er on height of the latest research and data on the topic. That said, I've never encountered whatever data that suggest fetal hiccups are associated with poor pregnancy outcomes – either in published research or anecdotally in the clinics at UT Southwestern.
When we see cord compression, information technology'due south usually in the presence of other events, such every bit:
- When the patient'southward water breaks early. Less fluid around the umbilical cord means in that location'due south a run a risk the babe could curlicue onto it, reducing blood flow. We typically put patients in the hospital after their water breaks to monitor the fetal heart rate as an indicator of potential issues.
- Labor and delivery. This happens fairly oftentimes. When the uterus contracts, it can compress the umbilical cord. When the uterus relaxes, the compression usually goes away. This appears as variable decelerations on the fetal heart monitor and is no cause for warning.
If we are to believe that hiccups are a result of cord pinch, it would stand to reason that fetuses would develop hiccups in these instances. But I've never seen this reported from any institution, and I've never seen information technology happen in my many years as a clinician.
Fetal heart rate is a known marking of well-being, as is being able to feel the babe move. In a 2017 study published in BMC Pregnancy and Childbirth, 150 women who had stillbirths in the third trimester responded to a poll regarding their memories around fetal movement, including fetal hiccups. The researchers compared these women'southward responses with those of 500 women who had live births or were still pregnant in the aforementioned timeframe.
Approximately 80 pct of women in both groups remembered experiencing fetal hiccups – in that location was no pregnant difference between the responses of either group of women, suggesting that fetal hiccups are non associated with adverse pregnancy outcomes. The same was true when the data were adjusted by maternal historic period, body mass index, smoking, or whether the patient felt daily or prolonged hiccups.
Slightly more women who had a stillbirth recalled daily fetal hiccups than those in the command group – 58% vs. 44% – only when this many report daily hiccups, it can't exist used equally a marker for a fetal problem.
How can I tell hiccups from fetal kicks?
Hiccups typically have a regular rhythm and occur in the same part of the belly over and over for a few minutes. Hiccups volition experience like a jerking or pulsing jump, which may motion your belly a bit.
Kicks typically are not rhythmic and will occur all around the belly. "Kicks" may be the baby'due south head, arms, lesser, or feet bumping against your insides, and they sometimes feel and look like a rolling movement rather than a quick jab.
What if I'm worried virtually the baby's movements?
Someday yous are concerned, reach out to your Ob/Gyn or certified nurse-midwife. We would rather you call the states than sit and worry about something that may not exist cause for alert. Information technology's important to call your prenatal intendance provider if you notice negative changes in fetal activity, such as drastically reduced movement during typically high-action times.
However, we encourage you to accept episodes of fetal hiccups for what they are – normal, not-harmful, and pretty beautiful! – bursts of fetal motility.
