Premature aging of the placenta is dangerous because the placenta is impregnated with salts, it reduces the number of blood vessels and the child begins to suffer from lack of nutrients and oxygen. Especially dangerous lack of oxygen to brain tissue changes that occur at the same time, may be irreversible.
The main function of the placenta
The placenta is an organ that is produced only during pregnancy and ceases to function when the pregnancy ends. It is a disc with one hand buried in the wall of the uterus, and the other side coupled with the fruit cord in which pass the blood vessels.
The main functions of the placenta are:
- separation of genetic heterogeneity of organisms of mother and child and the prevention of possible immunological conflict between them;
- delivery to the tissues of fetal arterial blood carrying nutrients and oxygen;
- excretion fetal venous blood from products of metabolism, and carbon dioxide;
- Warning of contact with the body of the fetus to toxic substances from the mother's body;
- secretion of hormones, to maintain a state of pregnancy, fetal growth and development;
- transmission from the mother to the fetus protective antibodies
Antibodies - "soldiers' immunity
to various infections that will protect the baby in its first few months after birth.
How is placenta
The placenta begins to function at 12 weeks of pregnancy, she is completely in control since the 16th week of pregnancy. In the future, the placenta adapts to the needs of the developing fetus and growing with its growth. Fully placenta matures at the end of pregnancy. From about the 36th week, the placenta there salt deposits
The deposition of salts - a disease of old men?
Begin zapustevat small blood vessels - a process known as aging of the placenta. Physiologically it is needed - reduces a large number of blood vessels in order to reduce the risk of bleeding during childbirth. But if labor does not occur in time (prolonged pregnancy) or premature aging of the placenta takes place, the lack of oxygen and nutrients to the fetus begins to suffer.
The degree of maturity of the placenta revealed during the ultrasound. In conjunction with the term of pregnancy is a very important indicator. The placenta has 4 stages of maturation: Zero - up to 30 weeks of pregnancy, the first - 27-36 weeks, the second - 34-39 weeks, the third (it corresponds to the beginning of the aging of the placenta) - after 36-37 weeks.
Why can begin premature aging of placenta
Premature aging of the placenta may start at a different sort of traumatic lesions of the uterus or the impact on the mother transferred diseases and intoxications. Traumatic injuries occur when the uterus abortion, difficult births in the past, wrong location of the placenta in the uterus (close to the inner zevu - out of the uterus) during this pregnancy, placental abruption, uterine wall stretching in multiple pregnancy or polyhydramnios.
Premature aging of the placenta may also result in various endocrine disorders (e.g., thyroid
Thyroid disease - women at risk
Diabetes mellitus), any acute illness or exacerbation of chronic (especially chronic pelvic inflammatory disease), diseases of the pregnant woman. What matters is the presence and severity of late toxicosis of pregnancy, any exogenous intoxication (delivery of toxic substances in the mother's body from the outside), for example, industrial hazard, smoking, drinking alcohol during pregnancy, drugs of various drugs without the consent of a doctor.
In what appears and the risk of premature aging of the placenta
When the third stage of maturation of the placenta has begun earlier than 36 weeks of pregnancy (or the second stage before 32 weeks), then it is a sign of premature aging. If you find this feature during an ultrasound examination of the fetus is established a special monitoring in order to detect signs of hypoxia, he (oxygen starvation).
Typically, small changes in the placenta do not cause any complications in the fetus and not require correction. Such changes are common and are usually hereditary, that is, are the individual feature of this woman.
If significant changes in the placenta of the fetus is always suffering, especially suffering from tissue that is most in need of oxygen - the tissue of the brain. If hypoxia continues for a long time, in the brain may be irreversible changes. "Outstanding" status of the fetus, especially, frequent heartbeat - the heart begins to contract more frequently to apply more blood to suffer from a lack of oxygen to the tissues. The survey is conducted with the help of special equipment - heart monitor.
This condition is called placental insufficiency
Placental insufficiency - deviation from the norm
It requires emergency treatment. If the gestational age allows, conducted delivery, in the earlier stages of pregnancy - treatment that restores utero-placental circulation.
Every woman should know what the premature maturation of the placenta than it is dangerous for the baby, as well as the fact that the early detection of this disease it is quite possible to compensate.
