The aging of the placenta - it's really scary?


the aging of the placenta placenta - an organ that carries out all kinds of communication between the pregnant woman and the fetus.Therefore, any violations of the structure, location or operation of the placenta necessarily affect the status of the mother and child.Many women are afraid of the word "aging of the placenta."Is it really so terrible?

What is placenta

placenta is also called child seats.It is designed to nourish, to supply oxygen to protect the growing fetus from infections and maintain a state of pregnancy (in the placenta produces a number of hormones that support pregnancy).Non-pregnant women do not have a placenta, it is formed during pregnancy and ceases to exist after the birth.

placenta has the form a disk with a diameter of about 20 cm, 3 cm thick and weighing about 0.5 kg.One side of the disc facing the fetus and from the umbilical cord moves, which are arteries and veins, bringing and carrying away the blood of the fetus.On the other side of the disc looks like villi, buried in the wall of the uterus and is washed by the blood of the mother.

through a thin placenta comes metabolism improves metabolism and losing weight without dieting Improves metabolism and losing weight without dieting : from the maternal blood to the blood of the embryo penetrate oxygen and nutrients and, in the mother's blood from the fetus receives carbon dioxide and metabolic products.

As the placenta is formed and aging

placenta begins to form on day 12 of pregnancy, when the fertilized eggembedded in the lining of the uterus.Until that time, the power of the embryo is carried out independently, using its own resources.Up to 12 days of pregnancy the egg is not associated with the mother's blood and therefore toxic effects (reception mother liquor, various drugs, smoking and so forth) can not damage it.After 12 days of starting the formation of the placenta, and all the toxic effects on the mother affect the condition of the fetus.

Fully placenta is formed by the end of the third month of pregnancy, then it is changing, adapting to the needs of the growing fetus.

placenta grows with the growth of the fetus, as well as the child needs more and more nutrients, weight and size of the placenta are increasing.Placental villi acquire branched form, they increase the number of blood vessels.The placenta reaches full maturity a month before the birth.

In late pregnancy (at 36-37 weeks) begins a gradual physiological aging of the placenta, accompanied by a decrease in the area of ​​its exchange surface, the appearance of areas of salt deposits.During birth the placenta is born after the fetus looks like a disk weighing about 0.5 kg.

There are several degrees of maturity of the placenta (placenta maturity is determined by ultrasound).Each has its own gestation maturity mismatch is detected and if these figures, we speak of premature aging of the placenta.

Why placenta is aging prematurely

In some cases, the process of aging of the placenta begins too early, and the placenta can not provide the child with all the necessary nutrients and oxygen.About premature aging of placenta say when a second degree of maturity before 32 weeks, and the third - before 36 weeks of pregnancy.

in premature aging of the placenta violated its blood supply in the placenta develop metabolic disorders, which necessarily affects the state of the fetus, that is, there are signs of placental insufficiency.Risk factors for premature aging of the placenta are injured uterus toxic effects on the mother:

  • previous abortion and obstructed labor (they break the power structure and the wall of the uterus);
  • endocrine disorders (eg, thyroid disease Thyroid disease - women at risk Thyroid disease - women at risk or diabetes mellitus - threatening and incurable disease Diabetes - threatening and incurable disease , which almost always affects the state of the blood vessels);
  • mother any chronic disease (e.g., renal disease, cardiovascular cancer and so on);
  • smoking;
  • blood incompatibility of mother and fetus of Rh factor in repeat pregnancies (first pregnancy usually passes without conflict);
  • severe toxicosis second half of pregnancy (preeclampsia);
  • infection of the uterus;
  • attachment of the placenta close to the cervix or partial detachment;
  • multiple pregnancy.

signs of placental insufficiency and its consequences

Placental insufficiency is often asymptomatic, so that's why you need constant monitoring obstetrician-gynecologist of female consultation and an ultrasound.

failure of function of the placenta during early pregnancy can lead to the formation of a frozen pregnancy or congenital malformations of the fetus.After the fourth month of pregnancy, placental insufficiency leading to fetal hypoxia fetal hypoxia - the consequences of lack of oxygen in the body Fetal Hypoxia - the consequences of lack of oxygen in the body (insufficient supply of oxygen, which is why the first to suffer brain child) and delay its development.

What if placental insufficiency still came

If a pregnant woman is constantly observed the doctor, the placental insufficiency, as a rule, it does not threaten, as the doctor will take all necessary measures to eliminate violations of blood supply to the fetus andprevention of serious complications.If outpatient treatment does not help and resolve placental insufficiency fails, send a woman to the maternity hospital to maintain pregnancy.

Remember refuse treatment of placental insufficiency can not be, it can seriously affect the health of the child.
