What are the effects of a thin placenta?

The thickness of the placenta after a woman becomes pregnant is very critical to the growth of the fetus. A placenta that is too thin or too thick can easily affect the normal growth of the fetus. Women need to have regular prenatal checkups during pregnancy so that they can keep track of the condition of the fetus and placenta at any time. In general, a placenta that is too thin can easily lead to fetal hypoxia, which can easily affect the normal development of the fetus and cause slow development.

What are the effects of a thin placenta?

The normal thickness of the placenta is between 3.6cm-3.8cm. When the thickness of the placenta is lower than the normal value, it is considered to be too thin. There are many reasons for a thin placenta, such as endocrine disorders of the pregnant woman herself or other pathological factors. A thin placenta requires active treatment. If the placenta area is relatively large, it will not affect the blood supply to the fetus. However, if the placenta is thin and small, it will relatively affect the blood supply and oxygen supply to the fetus. The fetus may suffer from developmental delay and fetal hypoxia during delivery. If the baby develops normally, there is no need to be nervous. It is recommended that pregnant women have regular prenatal examinations to observe fetal movements.

In fact, when a woman is pregnant, there is an organ called the placenta, which is used for substance exchange between the mother and the fetus. In fact, the placenta has a certain thickness and it changes as the pregnancy progresses. So, many people want to know, what is the standard for placental thickness?

What is the thickness of the placenta?

When a woman is pregnant, she will have a placenta, which is generally of a certain thickness. So, one wonders, what is placental thickness?

First, let us understand what the placenta is. The placenta refers to the transitional organ that grows from the embryo's embryonic membrane and the mother's endometrium during pregnancy in metatherian and eutherian mammals and is used to exchange substances between mother and child. When the fetus develops in the uterus, it relies on the placenta to obtain nutrition from the mother, while both maintain a considerable degree of independence. In addition, the placenta produces a variety of hormones that maintain pregnancy, so it is also an important endocrine organ.

In terms of placental structure, the placenta is a combination of embryonic and maternal tissues, and is composed of the amnion, chorionic villi and decidua basalis. And placental thickness, as the name suggests, is the thickness of the placenta. The normal value of placental thickness has a certain range. If it is below or exceeds the range, there may be a problem. The nutrients needed for fetal development are delivered to the fetus by the mother through the placenta, so the function of the placenta will directly affect the health of the fetus, and some changes in the fetus may also be reflected in the placenta. Therefore, in addition to paying attention to the fetus itself, expectant mothers should also pay attention to the placenta, be alert to problems such as placental insufficiency, and avoid fetal malnutrition or fetal hypoxia.

Placenta thickness standard

Many people know that the thickness of the placenta follows a certain pattern, and the thickness of the placenta is different at different stages of pregnancy. So, everyone wants to know, what is the standard for placental thickness?

In fact, many pregnancy and childbirth experts have clearly stated that the thickness of the placenta is completely different during different pregnancy cycles. Generally speaking, the thickness of the placenta will increase with the number of weeks of pregnancy. That is to say, the thickness of the placenta will be determined by the number of weeks of pregnancy (in millimeters). For example, at the 23rd week of pregnancy, the normal thickness of the placenta should be about 23 mm. By the time delivery is approaching, it is normal for the placenta to be less than 5 cm (50 mm) thick. If it exceeds the normal thickness, it is too thick. A thick placenta may be caused by abnormal conditions such as placental bleeding, placental edema, maternal and fetal blood type incompatibility, or abnormal fetal chromosomes. At this time, you need to go to the hospital for examination and treatment.

However, the measurement of the placenta is always affected by factors such as body position and fetal compression. Therefore, it is difficult to determine whether there is a problem with the fetus just by looking at the thickness of the placenta. In addition to the thickness of the placenta, there is another more important indicator called placental maturity. Therefore, when doing B-ultrasound, it is necessary to consider other factors in order to correctly judge the condition of the fetus.

How does the thickness of the placenta change?

We all know that paying attention to the condition of the placenta will help us judge the health and safety of the fetus in the pregnant woman's womb, and the placenta will gradually mature as the pregnancy progresses.
