What is the relationship between placental thickness and gestational age?

summary

As women, we all have the experience of pregnancy. When we are pregnant, we always pay attention to the situation of the baby in the belly and our own body. When I am pregnant, I also pay attention to the relationship between the thickness of the placenta and the gestational age, but there is not much connection.

What is the relationship between placental thickness and gestational age?

First, under normal circumstances, the thickness of the fetal basin is between 25-50 mm. According to the changes of the chorion, placental light spot and basement membrane of the fetus, the maturity of the fetal basin can be divided into four levels: 0, I, II and III, which is closely related to the development time of the fetus. The longer the pregnant woman is pregnant, the higher the maturity of the fetal basin.

The thickness of normal placenta is 3.6-3.8 cm, generally less than 5 cm. Membranous placenta is characterized by large and thin placental area and easy bleeding in the second trimester of pregnancy. If it is a small placenta can lead to intrauterine growth retardation, and low birth weight infants.

Third, the thickness of placenta can be measured by ultrasound. The thickness of normal term placenta is about 36 ~ 38mm, generally less than 50mm. We judge the gestational age through the baidu of the placenta is not much significance, there are a variety of circumstances will determine the thickness of the placenta, because intrauterine infection, hemolysis of the placenta due to edema will become thick.

matters needing attention

When we are pregnant, we don't care about the thickness of the placenta, as long as we are healthy and the placenta is normal. Generally, the relationship with gestational age is not too big, and we should not worry too much.
