What is placenta previa, not everyone knows. However, many pregnant women encounter this concept during the period of bearing their baby. Placenta previa is a pathology. It is due to the fact that the placenta in this situation is located in the lower part of the uterus. It can overlap the region of the internal pharynx partially or completely. This pathology is characteristic of one percent of all expectant mothers. If pregnancy proceeds normally, the placenta is located at the bottom of the uterus, the back wall and goes to the side. In this place, the best blood supply to the woman’s reproductive organ is observed. Presentation of the placenta on the posterior wall in most cases is able to protect it from various kinds of accidental injuries and injuries.
Complete presentation is called pathology, in which the placenta almost completely blocks the internal pharynx. Specialists also highlight the low location. At the same time, the edge of the placenta is below the level, but there is no overlapping of the area of the internal pharynx.
Placenta previa has several reasons. Most often, inflammation or various surgical interventions cause the development of this pathology. Placenta previa is more common in those women whose previous births were very complex. That is why this pathology is often observed in re-pregnant mothers.
Placenta previa. Symptoms
The doctor can identify placenta previa, the symptoms of which are considered, first of all, repeated bleeding, using an ultrasound examination. In this case, bleeding in a future mother arises absolutely at any time. They can become more frequent in the second half of the period of carrying the baby, since it is at this time that the so-called lower uterine segment is formed. In recent weeks, they are intensified by regular contractions of the uterus muscles. It is worth noting that during the detachment of the placenta, blood appears directly from the vessels of the uterus itself. As for the fetus, it does not lose blood. However, the baby is threatened by something else - oxygen starvation, because this part of the placenta will no longer participate in the gas exchange necessary for the child.
A pregnant woman should limit stress, sex life and various thermal procedures. In addition, sharp-type coughing movements, constipation, and vaginal examinations can also contribute to bleeding. If it was revealed a complete placenta previa, then do not be surprised that bleeding appears regularly and suddenly. Most often, this process is not accompanied by any severe pain.
In general, placenta previa can provoke a delay in the development of the child due to oxygen starvation, which has already been mentioned. Some experts associate with this pathology an incorrect presentation of the fetus, that is, oblique or pelvic. However, these events are in no way connected with each other.
If the patient consults a doctor with complaints of bleeding, the specialist first carefully examines the cervix and the walls of the vagina itself. For this, the doctor uses a special mirror. This is required in order to exclude the possibility of any injuries or pathologies, which are also characterized by blood discharge. In addition, in the event of a complete presentation of the placenta on ultrasound, such an examination of the uterus and vagina is generally not recommended.
Pregnant women with this pathology are placed in a special hospital. In this case, the expectant mother must mandatory observe bed rest, take those medications that her doctor appoints her. If bleeding in the late term is repeated very often, perhaps a caesarean section will be given to mom . Sometimes this method becomes the last chance to save the life and health of your child.
