Do babies poop in the womb? What to know about digestive system development

The fetal digestion system starts to develop in the womb at 5 weeks and continues to mature throughout the third trimester. They start absorbing nutrients from their mother immediately via the umbilical cord and placenta. Babies pee in the womb and accumulate meconium, which they pass as their first bowel movement after birth. Eating a well-balanced diet and getting adequate folic acid, iron, and other vital nutrients during pregnancy can help encourage the proper development of your baby’s digestive system.

Fetal digestion in the womb: Timeline

First trimester, conception to week 13

The embryonic period begins at 5 weeks when all your baby’s major systems and structures begin to develop. Their gastrointestinal tract starts to develop, and by week 9, all your baby’s vital organs have started to grow. Their stomach, liver, kidneys, and pancreas are all affected. By 10 weeks, the anus and rectum have formed, the kidneys have begun to produce urine, and the pancreas has started to produce insulin.

Between weeks 15 and 18, secretions are produced by your baby’s liver and pancreas. Your baby should be able to swallow by the end of week 21. Meconium, their first bowel movement, is produced in the intestinal tract. The fetal digestion system also works during the second trimester, and your baby’s sucking reflex is developing. If their thumb is close to their mouth, they may latch onto it. You might be able to see them doing this during an ultrasound exam after about 20 weeks.

Second trimester, weeks 14 to 27

Between weeks 15 and 18, secretions are produced by your baby’s liver and pancreas. Your baby should be able to swallow by the end of week 21. Meconium, their first bowel movement, is produced in the intestinal tract. The fetal digestion system also works during the second trimester, and your baby’s sucking reflex is developing. If their thumb is close to their mouth, they may latch onto it. You might be able to see them doing this during an ultrasound exam after about 20 weeks.

Third trimester, weeks 28 to 40

During the third trimester, your baby prepares for birth and life outside the womb. At 30 weeks, their bodies start absorbing minerals from the intestinal tract, preparing to take over from the placenta after birth. Most of your baby’s development completes at 31 weeks, and they will start to gain weight rapidly for the remainder of your pregnancy. Finally, your baby’s intestinal absorption reaches adult levels at 32 weeks pregnant.

Do babies eat in the womb?

Babies do not “eat” in the traditional sense of the word while in the womb, but they absorb all the necessary nutrients from their mothers. During pregnancy, the placenta evolves in the uterus and delivers nutrients and oxygen to your baby via the umbilical cord. Also, the placenta removes harmful waste and carbon dioxide from the baby’s blood. It produces hormones that help in the growth of your baby, protects the baby during pregnancy, and transfer immunity from you to the baby. In fact, until birth, the placenta serves as the lungs, kidneys, and liver, keeping your baby alive and healthy.

Do babies poop in the womb?

A baby pees in the womb, but they don’t usually poop there. Instead, babies’ first bowel movement, called meconium, builds up in the intestines while they’re still pregnant. Meconium is a thick, greenish-black substance made of mucus, amniotic fluid, lanugo, and bile. After birth, meconium is eliminated in the first bowel movement of your baby.

If your water breaks and you notice dark green stains or streaks in the amniotic fluid, consult your GP or midwife right away. This indicates that meconium has entered the amniotic fluid, and the baby may develop meconium aspiration syndrome (MAS), in which they breathe meconium into their lungs before, during, or after birth. The good news is that most infants with MAS who receive treatment fully recover.

How to support your fetal digestion system development?

Your baby’s primary source of nutrition is what you eat and drink. During pregnancy, folic acid, iron, calcium, vitamin D, DHA, and iodine all play important roles in your baby’s development. Consume a well-balanced diet and ensure that your prenatal vitamin contains iron, folic acid, and calcium. Consult your GP/midwife to ensure that you are getting enough calcium, vitamin D, DHA, and iodine.

A standard ultrasound exam between 18 and 22 weeks of pregnancy can reveal a lot about your baby’s digestive tract health to your healthcare provider. For example, an ultrasound may reveal structural problems and amniotic fluid abnormalities when the digestive system isn’t developing properly. If the ultrasound shows anything that concerns your provider, you will be subjected to additional tests, including a more detailed ultrasound, to learn more.
