The lower edge of the placenta crosses the internal cervical os

The situation where the lower edge of the placenta passes through the cervical opening is called placenta previa. Women with this situation are particularly prone to vaginal bleeding. Therefore, women must stay in bed and rest during the days before delivery, and try to choose a cesarean section to reduce the risk of delivery. Do not be tired and go to the hospital for examination in time. So what should I do if the lower edge of the placenta passes through the cervical opening?

If the lower edge of the placenta passes the internal os of the cervix, it is complete placenta previa. You don't necessarily have to stay in bed to rest. Just make sure to rest and don't overwork. Placenta previa is prone to vaginal bleeding. As the pregnancy progresses, the position of the placenta may rise. Pay attention to follow-up examinations. If you cannot raise the fetal position by yourself, you need to see a doctor if you have symptoms such as bleeding.

In the early stages of pregnancy, the placenta is located around the cervix. As the gestational age increases, the placenta will gradually grow upward. If the placenta is still near the cervix in the late stages of pregnancy, if it completely covers the cervix, it is a central placenta previa. If the edge of a partial placenta reaches the cervix, it is a partial placenta previa, which can easily cause vaginal bleeding. Currently, B-ultrasound is used to monitor the condition of the placenta as the gestational age increases.

We all know that our fetus will enter the placenta and come out through the placenta in the late pregnancy. Generally, the placenta has a fixed position, such as placenta anterior, placenta posterior, etc. The placenta needs to be kept at a certain distance from the cervix, otherwise it will affect the fetus and prevent natural delivery. If natural delivery is required, it will cause heavy bleeding. Normally, the distance between the placenta and the cervix should be greater than or equal to 3 cm.

So what does it mean when the lower edge of the placenta passes the internal cervical os? We all know that if the placenta is relatively close to the cervical os in the early or middle stages of pregnancy, then there is no need to worry. As the fetal gestational age gradually increases, the distance of the placenta will increase, but it will never rise to the normal position. Generally speaking, the position of the placenta will be determined after the 28th week of pregnancy, and it can still change before the 28th week of pregnancy.

In fact, if the placenta is too close to the cervix, it is very easy to bleed. Normally, we may see that some pregnant women need to walk carefully on the road and cannot walk too fast. The reason for this is that the placenta is too close to the cervical opening. If they walk too fast, they may suffer vaginal bleeding, which may lead to miscarriage of the fetus. Some expectant mothers are in serious condition and need to lie in bed for the entire pregnancy. Therefore, some expectant mothers lie in bed to rest not because they are weak or delicate, but because the placenta is positioned too low.

If you find that the placenta is located too low in the late pregnancy, you must be extra careful in your daily life. You should not overwork, exercise for long periods of time, and even walk carefully. Because the position of the placenta has been determined at this time and will not change. This position of the placenta is very bad for expectant mothers. Many expectant mothers want to give birth naturally, but in this case, natural birth is not allowed.

Therefore, if the lower edge of the placenta passes the internal os of the cervix, it means that the placenta is too low and the fetus cannot be delivered naturally during delivery, and only a caesarean section can be chosen. If you want to give birth naturally, it will cause heavy bleeding. The most taboo thing for pregnant women during childbirth is heavy bleeding, because heavy bleeding can directly lead to the death of the mother. Therefore, in general, if the placenta is too low, a caesarean section is chosen for the safety of mother and child.
