Low placentation during pregnancy: borderline
Everyone knows that pregnant women should be treated with increased attention to their health.But not all during pregnancy depends on the expectant mother.For one of these cases applies to low placentation during pregnancy.Many women heard such a diagnosis from a doctor, immediately panic.Although, in fact, the reason for this is not (subject to all medical recommendations).Low placentation refers not to pathological, and to the border states, and often, at the end of pregnancy no longer pose a threat.Currently, about 30-40% of women (especially living in cities) face with this condition during pregnancy.And 99% of these births are completed safely.
role of the placenta during pregnancy
placenta, or afterbirth, is a flat cake with a diameter of about 15 cm and a weight of about 1.5 kg.The are many placenta blood vessels which link between the organism mother and fetus.
numerous functions of the placenta and its role in pregnancy is enormous.
placenta secretes hormones, especially progesterone Progesterone - norm and pathology , which is responsible for maintaining pregnancy.Also, it is through the placenta to the fetus receives all the nutrients, vitamins, minerals and oxygen and removes carbon dioxide.On how the fetoplacental (plodovoplatsentarnaya) system depends on the state and development of the unborn child.
What is low placentation
Normally, the placenta is located on the front or rear wall of the uterus, some going into her bottom.This localization of the placenta is optimal, it is here that a well-developed circulatory system, which creates favorable conditions for the functioning of uterine blood flow.About low placentation say, when the placenta is below 5.5 cm internal os.Nizkuyu can placentation sravnit the incomplete placenta praevia (when afterbirth overlapping internal Snapdragon partly or wholly).However, the low placentation has a favorable course.
low placentation usually detected in the first trimester, third trimester, but the specific reasons for the unrest there.Case is in the period can independently pregnancy, the placenta migrate ie go higher, toward the bottom of the uterus.It occurs in late pregnancy, lasts about six to ten weeks and ends at 34 weeks.Migration of the placenta depend on the uterine wall on which it is located.With the localization of the placenta on the anterior wall of the uterus it is faster migration.
reasons for low placentation
exact causes of the low position of the placenta are unknown.But noted that the low placentation more common in multiparous women than in nulliparous.Low placental help change the inner wall of the uterus (the endometrium) caused by inflammation.Predisposing factors include low placentation:
- complicated childbirth (postpartum bleeding, manual removal of placenta, postpartum endometritis);
- abortion and diagnostic curettage of the uterus curettage - how dangerous it is? ;
- uterine fibroids, endometriosis Endometriosis - a serious problem with serious consequences uterus;
- chronic endometritis;
- cesarean section or removal of fibroids;
- multiple pregnancy;
- woman's age (over 35 years);
- placenta previa in a previous birth;
- parity (a large number of births).
How does the pregnancy is low placentation
As fetal growth increases the pressure on the uterus.There is compression of blood vessels of the placenta, which is a violation of utero-placental blood flow.This leads to the development of chronic fetal hypoxia Chronic fetal hypoxia - serious consequences , sometimes lagging behind its intrauterine development.Pregnant marked low blood pressure, weakness.Any physical stress can cause bleeding.Often develop anemia during pregnancy.
The most severe complication is the premature detachment of the placenta, and abortion.
recommendations for pregnant
At low placentation pregnant women should comply with certain conditions:
- sexual rest;
- limit any physical activity;
- avoid stress, fatigue;
- not lift his arms up sharply;
- avoid public transport.
