Is there fecal matter during pregnancy?

Mothers know that babies have to have feces within 24 hours after birth, and most normal babies will have feces within 12 hours after birth. Fetuses are feces already formed in the mother's body. The formation of feces is probably in pregnancy 20 Above the age of week, the color of feces is dark green, which is exhausted 2 to 4 days after the baby is born.

So the question is coming, the time of fecal formation is so early, does the fetus have fecal matter during pregnancy? If so, where did these excreta go?

Urine of the fetus during pregnancy

The fetal urine is actually one of the important sources of amniotic fluid. The fetus already has urine in the bladder at 14 weeks of gestation. By the second trimester, the fetus can discharge urine. In fact, the most original urine is the fetal swallow After entering the amniotic fluid, do you feel a little weird after hearing it? The amniotic fluid and urine of the fetus are being used in this cycle, but the urine of the fetus is not dirty, which is the real life of the fetus.

Fecal feces during pregnancy

In general, fetuses will not discharge feces when they are not born, but for some reason, such as severe uterine hypoxia caused by the umbilical cord around the neck, or early water breakage caused intrauterine infection, or uterine contractions , Or expired pregnancy, etc., may cause the fetal anal sphincter to relax and discharge the feces in advance, the feces will be discharged into the amniotic fluid, the amniotic fluid will become cloudy, and even amniotic fluid meconium contamination will occur, which is a relatively common clinical phenomenon. It is easy to suffocate the fetus. Therefore, if the amniotic fluid meconium is seriously polluted, it may be necessary to terminate the pregnancy early by caesarean section.

And after 20 weeks of pregnancy, as the fetus continues to grow, the fetus will accumulate in the fetal intestinal tract, so in order to prevent the fetus from expelling feces and prevent the amniotic fluid from being contaminated by the feces, the pregnant mother should go to the birth inspection on time, regularly Monitor the baby's health.

If the feces are discharged into amniotic fluid, the newborn will easily inhale the amniotic fluid containing feces, resulting in "fetal inhalation syndrome". Generally, before 34 weeks of pregnancy, amniotic fluid is not easy to have feces, which means that if it is a premature baby, it is not easy to have fecal inhalation, but if it is a full-term baby or an expired pregnancy, fetal inhalation may occur.

Therefore, when the newborn is born, the doctor will promptly suck up the amniotic fluid and fecal secretions of the newborn's mouth, nasal cavity, and throat to prevent the newborn's fetal inhalation.

Therefore, in summary, fetuses have fecal matter during pregnancy, and these feces will be directly discharged into amniotic fluid.

Of course, the above excretion pathways are not all the metabolic pathways of the fetus. In fact, throughout the pregnancy, the main metabolic pathways of the fetus are completed by the umbilical cord. There are three blood vessels in the umbilical cord, a vein, and two arteries. The vein is responsible for export, and the metabolites produced by the fetus are exported to the pregnant mother through the vein of the umbilical cord, and then discharged from the pregnant mother to the body. This process is also quite magical!
