How many weeks after the fetus is prone to hypoxia

After pregnancy, the fetus is very likely to suffer from hypoxia. If the fetus is deprived of oxygen, it can easily lead to fetal suffocation or even affect the fetal life. Therefore, once this situation occurs, pregnant mothers should pay attention to it. So, after how many weeks does the fetus become prone to hypoxia? Below, the editor will give you a detailed introduction to this knowledge, and I hope pregnant mothers can learn from it.

How many weeks is the fetus prone to hypoxia

The fetus in the late pregnancy, that is, from 8 months or 28 weeks, is prone to hypoxia.

Fetal hypoxia is fetal (intrauterine) distress, which means that the fetus has signs of hypoxia in the uterus, endangering the health and life of the fetus. As the baby grows during pregnancy, the space in the uterus becomes smaller, making it inconvenient for the baby to move. If the umbilical cord is wrapped around the neck, it is not easy to get it out. In addition, the placenta ages in the late pregnancy and the oxygen supply will be insufficient. Therefore, fetal distress mainly occurs during labor and can also occur in late pregnancy. The late pregnancy is also called late pregnancy. According to the cycle, the period from 28th to 40th week of pregnancy is called late pregnancy. In terms of months, it is the last 3 months of pregnancy, namely August, September and October. Therefore, the fetus in the late pregnancy, that is, from 8 months or 28 weeks, is prone to hypoxia.

What are the causes of fetal hypoxia?

First, placental abnormalities. Placenta previa is an abnormal position of the placenta, which can easily lead to fetal distress. The main reasons are the relatively poor blood supply to the lower uterine segment, which is prone to hypoxia. Once the area of ​​placenta previa detachment increases, the amount of bleeding increases, which on the one hand affects the exchange function of the placenta, and on the other hand, the anemia of the pregnant woman also reduces the oxygen supply capacity of the placenta. Placenta adhesion or accreta is caused by poor endometrial function at the site of placental attachment, excessive infiltration of the placenta into the uterine wall, and affected placental function. When the area of ​​early placental detachment increases to a certain extent, it affects the maternal-fetal exchange function, often leading to fetal distress or even stillbirth.

Second, umbilical cord abnormality. The umbilical cord is the link between the fetus and the placenta. Abnormal development or lesions of the umbilical cord affect the flow of blood in the umbilical vessels, leading to fetal distress. Such as umbilical cord around the neck, umbilical cord knotting, umbilical cord torsion, umbilical cord prolapse, umbilical cord hematoma, umbilical cord too long or too short, umbilical cord attached to the fetal membrane, etc.

The above is some content that the editor introduced to you about how many weeks the fetus is prone to hypoxia. I hope it will be helpful to you. From this, it can be seen that the fetus is prone to hypoxia at 28 weeks, and pregnant mothers will also feel very uncomfortable. Therefore, pregnant mothers should breathe oxygen appropriately to ensure the health of themselves and their babies.
