Amniotic fluid is the environment in which the fetus lives. Amniotic fluid has certain indicators, and whether it is high or low, it will have a certain impact on the fetus. Therefore, if expectant mothers can understand the amniotic fluid index, they can respond promptly if abnormal amniotic fluid index is found during the examination process. So, how much normal amniotic fluid is? Let's take a look below.
How much amniotic fluid is normal
The normal range of amniotic fluid index is 9-24CM. If it exceeds 25cm, it is diagnosed as polyhydramnios. If it is less than 8cm, it is due to oligohydramnios. In fact, both polyhydramnios and oligohydramnios are abnormal situations. Therefore, expectant mothers should attach great importance to them and take timely measures to deal with any abnormalities.
What causes polyhydramnios
1. Fetal malformations can easily lead to polyhydramnios, commonly caused by neural tube malformations. When the spinal membrane of anencephaly is exposed and extravasation occurs, it can cause excessive amniotic fluid production in pregnant women.
2. Chromosomal abnormalities can cause obstruction in the swallowing of amniotic fluid in pregnant women, leading to polyhydramnios.
3. Fetal edema. If the fetus suffers from immune system diseases such as edema, it can also cause polyhydramnios, such as hemolysis due to the mismatch between the mother and child's blood types, which can lead to an increase in amniotic fluid in the uterus of women.
For pregnant women, both polyhydramnios and oligohydramnios need to be taken seriously, especially after understanding the normal range of amniotic fluid. Pregnant women should pay more attention to testing the amniotic fluid value.
