Reasons for missed abortion can not completely identify not always. The cause of missed abortion could be a whole range of different factors, including random, which will not be repeated in the subsequent pregnancy. In any case, should be identified and if possible remove the cause of missed abortion.
Missed abortion - this is one of the varieties of miscarriage
Miscarriage - why you lose the most precious thing?
. In most cases, miscarriage is accompanied by spontaneous abortion (in the first half of pregnancy) or premature labor (in the second half of pregnancy). But sometimes the fruit that stops growing, it remains in the uterus, and then talk about missed abortion.
The reasons for missed abortion may be many, and sometimes they can not find out until the end. The most common reasons for missed abortion are hidden infectious and inflammatory diseases, hormonal disorders, the structure of the body and cervix, genetic and immune disorders.
The first reason for missed abortion - Infections
Infectious and pelvic inflammatory disease is the most common cause of missed abortion. Any infection, including gonorrhea
Gonorrhea - self-ruled
, A woman can take place secretly, quietly. But more often occur quietly as he called intracellular infections - chlamydia, mycoplasmosis and ureaplasmosis
Ureaplasmosis - inflammation of the urogenital system
. They cause inflammation and often goes unnoticed for a long time, leading to problems such as infertility and fetal death, ie, missed abortion.
There is a common infectious diseases, which often lead to the death of the embryo or fetus fading pregnancy. Such dangerous for pregnant infection combined group TORCH infections. TORCH word - an abbreviation of the Latin names of the most dangerous infections in pregnant women - toxoplasmosis, rubella, cytomegalovirus and herpes.
The second reason for missed abortion - hormonal disorders
All endocrine glands are interconnected and operated by a single center - the hypothalamic-pituitary system. Therefore, any violation of the endocrine glands can lead to the development of non-viable pregnancy. But more often the cause of miscarriages are dysfunction of the ovaries and thyroid. Violation of the functions of the other endocrine glands can cause fading pregnancy indirectly by affecting the function of the ovaries.
The reason for missed abortion may be a lack of female sex hormones or an excess of male hormones. The lack of estrogen or androgen excess (they suppress the synthesis of estrogens) - this leads to the fact that the mucous membrane of the uterus is not ready for the introduction and development of a fertilized egg. Therefore, the egg or can not penetrate the wall of the uterus and if pregnancy does not occur, or is being introduced, but the fetus can not develop - pregnancy does not develop ("empty" fertilized egg).
Lack of progesterone often causes miscarriage, since the main task is to contain progesterone uterus muscle contractions. However, this hormone has other functions and its deficiency can lead to the formation of non-viable pregnancy
Missed abortion - do not lose faith in yourself
The third reason for missed abortion - genetic disorders
Genetic disorders now recognized as a major cause of recurrent miscarriage, including the cause of missed abortion. Genital human cells contain a strictly defined set of chromosomes - specific structures in the cell nucleus, which contain genes (stretches of DNA) containing genetic information. Changing the number and structure of chromosomes can lead to the fact that the embryo or fetus will develop malformations incompatible with life. This will lead to fetal death and fading pregnancy or spontaneous abortion.
In most cases, these genetic disorders are inherited from parents. In this case, the child can be born only when using donor cells.
But recently, experts are increasingly faced with chromosomal disorders arising as a result of some external influence - radiation, smoking, alcohol, drugs, certain medications, malnutrition, etc. Eliminating the causes of chromosomal abnormalities (aberration) leads to the development of a normal pregnancy.
The fourth reason missed abortion - immune disorders
After pregnancy a woman's immunity decreases. It is a defensive reaction aimed at the fact that the mother's body does not reject the fetus, consisting of foreign cells. This allows to bear the child to full maturity. But sometimes Immune System Fails - this leads to the formation of antibodies to its own tissues by the mother or fetal tissues.
Fetus often leads to his death (for example, blood incompatibility of mother and fetus blood group and Rh factor). Sometimes antibodies are formed to own phospholipids in the blood plasma of the mother (antiphospholipid syndrome - APS). This leads to the fact that the blood vessels (including the blood vessels in the placenta) formed small thrombi. The blood circulation is disrupted. The fetus is deprived of oxygen and nutrients and dies.
The reason for missed abortion may be different disturbances in the structure of the uterus (congenital or acquired after birth abortions or heavy).
