The normal position of the placenta is usually located on the anterior and posterior walls, but some pregnant women may experience placenta previa or placenta previa. placenta previa and placenta previa are not the same. So, can placenta previa grow from placenta previa?
Low placenta can develop into placenta previa, which refers to placenta previa before 28 weeks of pregnancy, while placenta previa refers to placenta previa after 28 weeks of pregnancy. If the placenta has not yet grown after 28 weeks, it may develop into placenta previa. This is because before 28 weeks of pregnancy, the fetus has not fully grown, and the uterine volume of the pregnant woman is relatively small, but the uterine cavity may increase at any time. In this case, the placenta will move up with the increase of the uterus. Therefore, if the placenta is lowered, it may transform into placenta previa, but if not eliminated, it may transform into a normal placenta.
When the placenta is lowered, the distance between the lowest edge of the placenta and the cervical opening will be less than five centimeters, while for placenta previa, the placenta will attach to the lower segment of the uterus or to the lower edge of the placenta. Low placenta previa and placenta previa are mainly classified based on 28 weeks of pregnancy.
The placenta is an important channel for supplying blood and oxygen to the fetus. If the placenta is too low or completely anterior, it can easily affect the nutrition supply to the fetus, leading to adverse effects such as miscarriage. Therefore, when there are obvious abnormalities in the placenta, it should be taken seriously to avoid miscarriage or other major bleeding, while also ensuring the continued growth and development of the fetus.
