The posterior wall of the placenta refers to the position of the placenta in the uterine cavity of the female body. In daily life, we can see that many women have placenta previa and some women have placenta previa. These are two different manifestations. So, is the posterior wall of the placenta upper or lower?
There are two manifestations of placenta, one is placenta previa near the belly, and the other is placenta retroverted near the spine, while upper and lower pregnancy refer to a woman's belly protruding upwards or downwards. So theoretically, there is no direct relationship between these two.
The shape of a woman's body determines whether she is pregnant or not. If a expectant mother has a fuller figure, her belly is usually lower, while the baby inside her belly is usually upper. Therefore, the baby will have a good horizontal development in the belly, which will lead to symptoms of pregnancy.
If a woman's body is relatively thin and frail, she is basically wearing an intrauterine device (IUD). Due to this situation, women do not provide space for the fetus in their abdomen to develop horizontally, and can only allow the child to grow vertically in the body, causing the belly to tilt upwards. Another point is that if a woman's pelvic tilt is relatively small, it belongs to upper pregnancy, and vice versa, it belongs to lower pregnancy.
The position of the protruding belly in upper and lower pregnant women is different. Under normal circumstances, it is defined by the middle of the female abdomen. If it rises upwards, it belongs to the upper ring, and if it rises downwards, it belongs to the lower abdomen.
