Is it possible to recognize the symptoms of placenta previa?

The article is professionally consulted by Specialist Doctor II Lai Thi Nguyet Hang - Department of Obstetrics and Gynecology - Vinmec Ha Long International Hospital.

Usually, the placenta attaches to the fundus or body of the uterus. When the placenta attaches to the lower part of the uterus and partially covers or closes the cervix, it is called placenta previa. Placenta placenta can seriously affect a woman's pregnancy health.

Placenta placenta is located in front of the fetal path during vaginal delivery. Therefore, most cases with signs of placenta previa usually require cesarean section.
Common placenta previa in pregnant women include:
Low placenta previa: placenta attaches to the lower uterine segment. Placenta previa adheres to the margin: the placenta attaches to the edge of the cervical opening. Semi-central placenta previa: the placenta partially covers the opening in the cervix. Central placenta previa: the placenta completely covers the opening of the cervix.

Pregnant women with placenta previa can be recognized through the following signs:
During pregnancy, especially the last 3 months of pregnancy, the pregnant woman suddenly has vaginal bleeding without any known cause, no accompanied by abdominal pain, the blood is bright red and when it comes out, it clots.
The amount of bleeding is usually small in the first times, then the vaginal bleeding may repeat many times, the amount of bleeding in the following times is often more than the previous time.
If pregnant women move around a lot, do heavy work and have intercourse, ... will be more prone to bleeding.
Therefore, when there are signs of placenta previa, pregnant women should immediately go to medical facilities for timely examination and diagnosis, avoiding danger to both mother and fetus.
Currently, signs of placenta previa can be detected early by ultrasound even when there are no clinical manifestations.

The risk of placenta previa usually occurs in the following cases:
Having given birth many times. She had had an abortion and had multiple miscarriages. Had a uterine infection. Had placenta previa in a previous pregnancy.

Placenta placenta can lead to bleeding during pregnancy and childbirth, endangering the life of both the mother and the fetus.
For pregnant women: signs of placenta previa cause repeated bleeding during pregnancy, which can cause anemia in pregnant women, making it easier to give birth prematurely. Due to the lack of sphincter in the lower uterine segment, bleeding is common after delivery and the mother may go into shock due to massive blood loss. In the case of placenta previa sticking close to the cervix, after giving birth, the placenta is dissected, causing the cervix to open, bacteria easily penetrate and cause infection. In severe cases, a hysterectomy may be necessary if the placenta is firmly attached to the muscle of the uterus and does not separate from the lining of the uterus. For the fetus: signs of placenta previa cause the mother to become anemic during pregnancy, so the fetus is prone to malnutrition or fetal distress. When the mother has a lot of bleeding, the doctor who wants to save the mother must have an early cesarean section, even if the pregnancy is not yet full term. At that time, the preterm pregnancy can make the baby born with respiratory failure. In addition, because the placenta is located in the lower part of the uterus, it makes it difficult for the fetus to turn its head down, leading to a breech position. When seeing the above-mentioned signs of placenta previa, pregnant women should go to the hospital or antenatal clinic soon to be diagnosed and treated promptly by specialists.
