Many pregnant women pay attention to the position of the fetal placenta after pregnancy, as it can affect the way they give birth to their babies in the future. Some pregnant women find that their fetus has placenta previa, so what are the reasons for this?
Firstly, placenta previa in the fetus may be related to the woman's history of intrauterine procedures or intrauterine infections. If a woman has experienced multiple curettages, postpartum infections, and other conditions, her endometrium may be damaged to varying degrees, resulting in insufficient local blood supply to the endometrium. In order to obtain more nutrients, the placenta can only expand its area and extend to the lower part of the uterus.
Secondly, if a woman is carrying twins or multiple fetuses, it may also lead to placenta previa. Pregnant women who are pregnant with twins or multiple births may require a larger amount of nutrients, resulting in a need for a larger placental area, which may lead to placenta previa. In some statistical studies, it has also been found that the probability of having placenta previa in twins or multiple births is higher than in singleton births.
In addition, if the fertilized egg develops slowly, it may also lead to placenta previa in pregnant women. The fertilized egg usually forms in the female fallopian tube and develops during the process of descending to the uterus. When it reaches the stage where it can implant, it will implant in the uterus. If the fertilized egg develops slowly, it may implant in the lower part of the uterus, leading to placenta previa.
