What is the reason for premature placenta

summary

With the increase of gestational age, the maturity of placenta gradually increases. When the maturity of placenta reaches grade 3, it means that the placenta has aged and the oxygen supply capacity has decreased. Under normal circumstances, after 38 weeks of gestation, the maturity of placenta will reach grade 3, but if grade 3 of placenta is found before 37 weeks, it is premature placenta, which has a great impact on the maternal and fetal. Now let's share the reasons for premature placenta.

What is the reason for premature placenta

In fact, prolonged pregnancy is the most common cause of premature placenta. At this time, placental dysfunction, its material exchange capacity, far from meeting the needs of the fetus has increased, will lead to fetal distress and endanger the fetus.

The causes of placental aging are: pregnant women with hypertension, chronic nephritis, diabetes or pregnancy induced hypertension; pregnant women with cardiopulmonary disease, serious lack of albumin oxygen supply; improper diet. In addition, maternal uterine lesions and uterine malformations, congenital placental dysplasia and fetal malformations can also cause placental dysfunction and premature aging.

The number of operations increased. The reasons are: the increase of macromyosis: the fetus is too mature, hard head, poor plasticity; placenta aging, oligohydramnios, increase the incidence of fetal distress, but also increase the rate of cesarean section; uterine inertia, postpartum.

matters needing attention

When the function of placenta is low, it will affect the material exchange capacity of placenta, directly affect the oxygen supply of fetus, easily lead to fetal distress, and endanger the health and safety of fetus. Therefore, if placental aging is found, close monitoring should be paid attention to, and if necessary, induction of labor or cesarean section should be taken to terminate pregnancy.
