Do Babies Pass Gas in the Womb? Insights from Two Specialists
Pregnancy sparks many questions, including the curious wonder: do babies pass gas before birth? Discover the truth backed by expert opinions.
Whether you're preparing for your first child or your fifth, pregnancy brings an array of questions. It’s a remarkable and sometimes puzzling journey, unique to every mother and baby.
One surprising query that many expectant parents ponder is, “Can babies fart inside the womb?” It might sound odd, but countless women search for this answer once they start feeling their baby’s initial movements.
So, is fetal flatulence a real phenomenon?
From urination to gas and even burping, here’s what you need to understand about your baby’s digestive processes before birth.
Do Babies Release Gas Before Birth?
The simple answer is no—babies do not fart while in the womb. Passing gas requires swallowing air, which is impossible for a fetus surrounded by amniotic fluid.
“If babies can poop in the womb, you might think they could fart too,” explains Dr. Kim Langdon, a retired obstetrician and gynecologist. “However, farting would mean they swallowed air or gas, and since there’s no air to swallow, they simply can’t produce gas.”
No air intake means no gas formation.
Moreover, flatulence results from the digestion of food by bacteria in the colon, producing gas as a byproduct. Since fetuses do not digest food in utero, they do not generate gas.
What About Urination?
While babies can’t fart before birth, they do urinate. According to the American College of Obstetricians and Gynecologists (ACOG), fetal urination begins between 13 and 16 weeks of gestation, once the kidneys are fully developed.
The urine is mostly expelled into the amniotic fluid and then filtered through the placenta, maintaining a clean environment. By around 20 weeks, a significant portion of the amniotic fluid consists of fetal urine.
Do Babies Burp in the Womb?
Babies generally do not burp before birth. Since burping is caused by excess air in the stomach or esophagus, and the fetus’s lungs are filled with amniotic fluid rather than air, burps don’t occur.
“Burping requires air in the esophagus, which is not possible in the womb,” Dr. Langdon notes. “However, babies can swallow amniotic fluid, which might mimic some burping-like movements.”
Interestingly, fetal hiccups are common and healthy. These involuntary diaphragm spasms are signs of proper neurological development.
“Hiccups indicate that the baby’s nervous system is maturing correctly,” says Dr. Jennifer Taylor, an OB-GYN based in Baltimore, Maryland.
Do Babies Defecate in the Womb?
Typically, babies do not poop before birth. While rare instances occur, fetal defecation is uncommon.
Babies receive nutrients through the placenta and umbilical cord without digesting food traditionally, so waste production is minimal during pregnancy.
“Babies don’t digest food directly,” Dr. Langdon explains. “They absorb nutrients from the mother’s blood via the placenta. They may swallow amniotic fluid along with cells and debris like lanugo hair and vernix, but these aren’t digested. This material later forms the first stool known as meconium.”
In some cases, babies pass meconium before birth, which can lead to meconium aspiration syndrome (MAS). Occurring in about 13% of births, MAS often prompts healthcare providers to expedite labor to reduce risks.
What Are Those Early Flutters Then?
The fluttering sensations expectant mothers feel are not caused by gas but by tiny movements of the baby’s hands and feet.
“Between 16 and 22 weeks, these flutters are usually little kicks and stretches,” Dr. Taylor explains. “As pregnancy advances, movements become stronger and may include hiccups or reflexive actions.”
Final Thoughts
Though babies don’t fart in the womb, they undergo incredible growth and development from conception to birth. Every cell, organ, and bone forms during this time. While gas won’t be part of their prenatal experience, rest assured—it’s a natural milestone awaiting them after arrival.
