Hypoplastic placenta is defined as placenta attached to the lower uterine segment and less than 70 mm from the internal cervical os, but not covering the internal cervical os. The classification and degree of low lying placenta can change with the progress of pregnancy and labor. Clinically, it is recommended to use the last examination result before delivery to determine the above classification and use it to guide the choice of clinical delivery method. Usually in late pregnancy, the placenta will move and grow to a normal position by about 28 weeks, and only if the placenta is still low lying is it diagnosed as low lying placenta. If the placenta is less than 20mm away from the inner cervical opening, the success rate of vaginal trial of labor is low and the bleeding is high, so a cesarean section can be chosen. However, if the distance between the placenta and the endocervix is greater than 20mm and less than 70mm, it is possible to choose vaginal trial of labor, which has a certain success rate and the amount of bleeding is lower than that of cesarean delivery, but it is still necessary to listen to the doctor’s opinion on the choice of delivery method to avoid accidents. Therefore, it is necessary to review regularly during pregnancy to determine the position of the placenta. Pregnant women with low lying placenta should rest in bed absolutely to prevent bleeding caused by activities. Lateral lying position is appropriate to improve the blood supply to the placenta. At the same time, strengthen nutrition and take more food rich in protein and vitamins, such as animal liver, fish, beans, black fungus, etc. as well as fresh vegetables and fruits to correct anemia and strengthen resistance. You can relax by reading books, listening to music, etc. to avoid bad emotions of tension and anxiety. If there is abnormal bleeding seek medical attention promptly.
