Do you know how babies absorb nutrients in their mother's womb? The fetus lives in amniotic fluid at all times, and amniotic fluid also contains a large amount of nutrients. Starting from mid pregnancy, every prenatal check-up checks the depth of amniotic fluid, which can be related to the life of the fetus. Next, let's take a look at the normal value of amniotic fluid depth at 33 weeks of pregnancy.
A depth of 3-7 centimeters in the late stage of pregnancy is considered normal, while a depth exceeding 7 centimeters indicates an increase in amniotic fluid. An amniotic fluid index of 8-20cm is considered normal amniotic fluid volume. When the amniotic fluid index is less than 5cm, it indicates oligohydramnios and pregnancy should be terminated as soon as possible. Oligohydramnios in late pregnancy is mostly caused by placental dysfunction, and abnormal development of the urinary system can also lead to oligohydramnios, but it is rare and can sometimes be detected by ultrasound examination. In the late stage of pregnancy, if the umbilical cord wraps around the neck, it is generally not possible to turn it around again. A cesarean section should be performed under the advice of a doctor.
In late pregnancy, amniotic fluid can reach up to 1000 milliliters. In the last 2 to 4 weeks of pregnancy, the amount begins to decrease, and can be reduced to 550 during an expired pregnancy. If the amount exceeds 2000 during pregnancy, it is called polyhydramnios, and if it is less than 300 in late pregnancy, it is called oligohydramnios. A depth of 3-7 centimeters in the late stage of pregnancy is considered normal, while a depth exceeding 7 centimeters indicates an increase in amniotic fluid. An amniotic fluid index of 8-20cm is considered normal amniotic fluid volume. When the amniotic fluid index is less than 5cm, it indicates oligohydramnios and pregnancy should be terminated as soon as possible. Oligohydramnios in late pregnancy is mostly caused by placental dysfunction, and abnormal development of the urinary system can also lead to oligohydramnios, but it is rare and can sometimes be detected by ultrasound examination. In the late stage of pregnancy, if the umbilical cord wraps around the neck, it is generally not possible to turn it around again. A cesarean section should be performed under the advice of a doctor.
The above is the encyclopedia introduction about the normal value of amniotic fluid depth at 33 weeks of pregnancy. In short, amniotic fluid is the basic condition for the survival of the fetus in the mother's body, so women will check the amniotic fluid index during pregnancy, because for pregnant women, only when the amniotic fluid index meets the standard can it provide guarantee for the growth of the fetus.
