Why is a placenta formed?
Bearing is an organ arising only during pregnancy. It is used to directly supply nutrients, metabolism products and oxygen to the child. Thanks to this, there is a permanent exchange between the mother's and child's bloodstream. In the normal course of pregnancy, the placenta locates on the wall of the uterus.
Leading placenta as a pregnancy complication
In approximately 0.1-1% of all pregnancies, a placenta is present. It arises when the organ places itself directly over the mouth of the cervix or in its immediate vicinity. It is located partly or completely in the lower part of the uterus, right next to the cervix or completely covering it. This is not a win-win situation. It is considered a pathology, which is the most important cause of bleeding in pregnancy. In extreme cases, it leads to hemorrhage.
The placenta is dangerous because its location means that when the cervix opens and stretches during delivery, it will be pulled out of the uterus wall, where it is nested. In the normal course of pregnancy, the placenta is born right after the birth of the child.
There are different degrees of severity associated with the placenta prevailing, determined by how close the placenta is to the cervix, whether it covers it or not.
- type I and II is considered to be a smaller problem,
- type III and IV represent a serious problem
Often the term placenta prevails abused by pregnant women, which use it to describe a low seating.
Who is exposed to the placenta?
All causes of the placenta are not known. It is known what are the factors increasing the risk of irregularities.
- the lowest risk for placenta previa occurs in the first pregnancy, increases with subsequent deliveries. This is because the changes in the uterine mucosa remain after subsequent pregnancies, they are less adapted to implantation. Multiparities have a 5% risk of developing placenta prevalence,
- the risk of developing a placenta is increasing in women who have had a problem in previous pregnancies,
- previous curettage of the uterus,
- Caesarean section
- in vitro fertilization,
- multiple pregnancy (pre-placenta due to increased placenta size)
- fetal birth defects,
- pregnant in old age.
How is a placenta diagnosed?
For diagnosis of a placenta ultrasound is necessary. Increasingly used is also magnetic resonance imaging. The placenta can be diagnosed after 20 weeks of pregnancy, when the placenta is in the lower part of the uterus and covers the mouth of the cervix.
Signals that inform about the problem are spotting and bleeding during pregnancy, usually unexpected, occurring at night, for example. Bleeding is usually mild and rather painless and may be associated with it rhythmic contractions of the uterus. After the first bleeding, there are more that occur more often and are more abundant.
However, bleeding occurs only in 20% of cases of established placental placenta. In as many as 80% of cases, a woman does not notice any symptoms, and the diagnosis indicating a pre-placenta is taken by surprise.
Lead placental treatment
The procedure depends on the age of pregnancy. Because of the seriousness of the situation most often hospitalization and drug administration are necessary. It is always necessary close monitoring of pregnancy, usually limiting activity to a minimum, mainly lying pregnant and using the support of loved ones. Intercourse is inadvisable. It is also necessary to change your diet, which should be high in fiber so that you can pass stool without any problem.
Sometimes the problem goes away on its own. The younger the pregnancy, the greater the chance that the problem with the placenta will disappear. This is because the placenta can move with the growth of the fetus and uterus. This is confirmed by statistics - in as many as 30% of all pregnant women before 20 weeks of pregnancy, the placenta is located next to the cervix.
Often, prevalence of placenta is associated with incorrect placement of the fetus, e.g. gluteal. Unfortunately, the placenta may be conducive to occurrence fetal defects, anemia, intrauterine growth retardation. It is also dangerous for the mother. In an extremely unfavorable location, it may end up removing the uterus.
The placenta is an absolute indication for ending pregnancy by caesarean section. Only in a few situations (when the placenta does not obstruct the uterus) is delivery possible by nature.
Finally, good news. Although the placenta is a serious problem, as much as 99% of pregnancies are successful. That is why it is worth keeping calm and not stressing over the supply, but following the recommendations of the attending physician.
