Low placentation in pregnancy - 20 weeks

An important factor in the current pregnancy is the place of attachment of the placenta and its location in relation to the uterus of the uterus. This parameter was called "placentation" in midwifery. Let's talk about it in more detail and find out: why at carrying out of US on 20 week of pregnancy the low placentation can be diagnosed, than she threatens, and what rules the pregnant woman should observe at such infringement.

What is low placenta?

As you know, while the baby is in the mother's womb, all the useful substances come to him through the placenta, an organ that is formed only during pregnancy. In addition, oxygen, which is necessary for any organism, the fetus receives through it, along with blood.

The formation of this organ occurs directly in the place where the egg cell was attached to the uterine wall after fertilization. Usually this is the anterior or posterior wall of the uterus, closer to its bottom. However, it is not uncommon for implantation to occur in the lower part of the uterus, in close proximity to its internal throat. It is in such cases that low placenta arises later. A similar diagnosis is made by doctors when the distance between the extreme point of the placenta and the uterine pharynx is less than 6 cm.

Because of what is developing such a violation?

The causes of low placentation, found during pregnancy in 20 weeks, are not fully understood. Some doctors say that a significant influence on this parameter is provided by the way of life of the pregnant woman, while others believe that this factor has a hereditary dependence.

It is only known that the reason for the low attachment of the fetal egg at the very beginning of pregnancy can be damage to the endometrium. In such cases, the future embryo looks for a place that is not affected by the disease, and is attached in close proximity to the uterine throat.

What should a woman do if her low placentation is detected at 20 weeks?

As a rule, there is no medication for this disorder. Therefore, a woman is forced to constantly undergo ultrasound examinations to determine whether the placenta has changed.

The thing is that as the fetus grows and the uterus grows in volume, so-called "migration of the child's place" occurs, and the placenta rises, closer to the bottom of the uterus. This can occur up to 34-36 weeks of pregnancy. Therefore, the last ultrasound is performed at this time, with the aim of developing tactics for delivery.

As for the most pregnant woman, then at a low placentation, revealed during pregnancy at 20 weeks, she should observe a number of rules:

1. Completely eliminate the lifting of weights: even trips to the store in such cases must be given to the spouse. About any sport, fitness and yoga during this pregnancy is worth forgetting.
2. Sex with low placentas is also contraindicated. This is explained by the fact that increasing the uterine tone, which is inevitable when making love, can lead to partial detachment of the placenta.
3. At rest it is necessary, that legs were on a hill. So, many doctors at the time of sleep recommend to put a pillow.
4. Travel by car and public transport should be minimized.
5. If the diagnosis suddenly appeared discharge from the vagina bloody nature, without fail it is necessary to inform the doctor.

In most cases, the birth in this position of the placenta occurs naturally. However, in those cases when the placenta is located very close to the uterus of the uterus, an amniotomy can be performed-the opening of the amniotic fluid by artificial means.
