34 Weeks Pregnant and Baby Gets Hiccups Everyday
Some healthcare superstitions may be rooted in truth. But most of these hand-me-down stories are myths that persist, despite existence 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 fauna studies. According to ane researcher'southward 2012 article in BMC Pregnancy and Childbirth, it's suggested that hiccups in utero might be caused by compression of the umbilical cord. His possible explanation is that hiccupping might make a fetus move away from the cord, which would save the compression and render blood flow to normal.
All the same, I couldn't find the study, which involved fetal sheep, that he quoted.
Much similar the "vaccines crusade autism" lie, which has been perpetuated since a now-discredited written report in the late 1990s, people grabbed onto the idea that fetal hiccups could cause problems like preterm birth or stillbirth – none of which has ever been scientifically studied in human fetuses.
I tin can sympathise why patients might be worried about hiccups. It looks strange on ultrasound to see your baby jerking effectually in the womb. Information technology's simply natural to Google the miracle, only to discover article afterwards article suggesting that your pregnancy may be at risk.
Fetal hiccups are normal. Having hiccups does not hateful something is wrong with your babe, and you don't need to try to become rid of the condition. Let'due south look at the data to prove information technology and discuss what'south really going on in your belly with every hic, hic, hiccup.
What happens during fetal hiccups?
In the fetus, the diaphragm acts similarly to how information technology will when the baby is built-in. The diaphragm controls breathing, which is a rhythmic, intermittent movement. The fetus isn't animate 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 downward and outward displacement of the belly. Instead of the chest rising and falling with breaths like an adult'southward would, fetuses and babies tend to involve their bellies more. This gentle movement is undetectable by the pregnant patient.
Hiccups follow that aforementioned, rhythmic motility as breathing, merely more than forcefully. The entire fetal trunk moves in a jerking motion with each hiccup, which many pregnant patients tin experience. Just like 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 animate and fetal hiccups, which are non a danger to the fetus or the pregnancy.
What does the science say?
There are several bug with the study that suggests hiccups are associated with potentially dangerous umbilical cord pinch. The researcher speculates that hiccups are a hyper-reactive response to reduce claret menstruum from a knotted or compressed umbilical cord.
Umbilical cord problems are always high on our radar. Patients worry about this, and nosotros are always on peak of the latest research and data on the topic. That said, I've never encountered whatever data that propose fetal hiccups are associated with poor pregnancy outcomes – either in published research or anecdotally in the clinics at UT Southwestern.
When nosotros see cord compression, it'due south usually in the presence of other events, such as:
- When the patient's h2o breaks early. Less fluid around the umbilical string ways in that location's a chance the infant could scroll onto it, reducing blood flow. We typically put patients in the infirmary afterward their h2o breaks to monitor the fetal eye rate as an indicator of potential bug.
- Labor and commitment. This happens fairly oft. When the uterus contracts, it tin can compress the umbilical cord. When the uterus relaxes, the compression unremarkably goes away. This appears as variable decelerations on the fetal centre monitor and is no cause for alarm.
If we are to believe that hiccups are a effect of cord compression, information technology would stand to reason that fetuses would develop hiccups in these instances. Only I've never seen this reported from any establishment, and I've never seen information technology happen in my many years as a clinician.
Fetal heart charge per unit is a known marker of well-beingness, every bit is being able to feel the baby movement. In a 2022 study published in BMC Pregnancy and Childbirth, 150 women who had stillbirths in the 3rd trimester responded to a poll regarding their memories around fetal movement, including fetal hiccups. The researchers compared these women'due south responses with those of 500 women who had live births or were nonetheless pregnant in the aforementioned timeframe.
Approximately 80 per centum of women in both groups remembered experiencing fetal hiccups – there was no significant difference betwixt the responses of either group of women, suggesting that fetal hiccups are non associated with adverse pregnancy outcomes. The aforementioned was true when the data were adjusted past maternal age, body mass alphabetize, smoking, or whether the patient felt daily or prolonged hiccups.
Slightly more than women who had a stillbirth recalled daily fetal hiccups than those in the control group – 58% vs. 44% – only when this many report daily hiccups, it can't exist used as a marker for a fetal trouble.
How tin can I tell hiccups from fetal kicks?
Hiccups typically have a regular rhythm and occur in the same part of the abdomen over and over for a few minutes. Hiccups will experience similar a jerking or pulsing jump, which may motility your belly a bit.
Kicks typically are not rhythmic and volition occur all around the belly. "Kicks" may be the babe's caput, artillery, bottom, or feet bumping against your insides, and they sometimes feel and wait like a rolling motility rather than a quick jab.
What if I'm worried about the infant'south movements?
Anytime you lot are concerned, reach out to your Ob/Gyn or certified nurse-midwife. We would rather you call united states of america than sit down and worry near something that may not exist cause for warning. Information technology'southward of import to phone call your prenatal care provider if you notice negative changes in fetal activity, such as drastically reduced movement during typically high-activity times.
However, we encourage you to take episodes of fetal hiccups for what they are – normal, non-harmful, and pretty cute! – bursts of fetal motion.
To visit with an Ob/Gyn or certified nurse-midwife, call 214-645-8300 or request an appointment online .
