There is no way to determine the direction of growth of the placenta with the current level of medical care. Whether or not a low placenta can grow depends on the week of pregnancy at the time of the pregnancy. Before the 28th week of pregnancy, the placenta may grow up, but after the 28th week of pregnancy, it is very unlikely that it will grow up. Generally, before 28 weeks, if the ultrasound examination finds that the placenta is low, with the increase of pregnancy weeks, the uterus gradually enlarges, the lower part of the uterus elongates, and the position of the placenta will gradually pull upward, and the placenta may become the normal position of the placenta. After 28 weeks, especially after 32 weeks of pregnancy, if the ultrasound shows that the placenta position is still low, the possibility of upward movement of the placenta at this stage is very small, and a true placenta praevia or placenta previa is usually formed, and the pregnancy should be prolonged as much as possible to improve the survival rate of the fetus. During pregnancy, if a pregnant woman is found to have low placenta, she should avoid excessive physical labor, avoid squatting, and should prohibit coitus to avoid bleeding. Normally, pay attention to balanced diet, avoid eating cold, spicy and stimulating food, and maintain good laxative habit to avoid constipation. Pay attention to vulvar cleanliness and hygiene, wear loose underwear, don’t wear tight clothes, and go to the hospital regularly for pregnancy checkups. If vaginal bleeding or abdominal pain occurs, consult a doctor promptly to avoid danger.
