Anterior placenta, which means that the placenta is located in the front wall of the uterus, is a normal phenomenon and does not require special treatment. However, it will be more dangerous if it is placenta praevia, which is a manifestation of placental abnormality. It is mainly due to the fact that the placenta is attached to the lower part of the uterus, and even the lower edge of the placenta reaches or covers the inner mouth of the cervix, and its position is lower than the prenatal part of the fetus. If a fetal ultrasound shows that the placenta is positioned at the anterior wall and there is no other description, it means that it is a normal phenomenon, and there is no need to do any treatment in this case, because this is already normal in itself. However, if it shows that the placenta is in a lower position or clearly suggests placenta praevia, then it should be taken very seriously. This is because placenta praevia can cause painless hemorrhage in late pregnancy, and in severe cases, it can endanger the life of the fetus and the mother. If placenta praevia is diagnosed, regular checkups are needed, especially for women who are more than 6 months pregnant. There is no effective treatment for placenta praevia at this stage. Only in the late stage of pregnancy can the symptoms be controlled by sedatives and blood replenishing drugs, such as salbutamol sulfate or magnesium sulfate. Therefore, when women do prenatal checkups, if there is something they do not understand, they can consult the clinician, and must be clear about whether it is anterior placenta or placenta praevia.
