Causes of miscarriage are many and varied in nature.
fetal chromosomal abnormalities are most often the cause of miscarriage in the first trimester of pregnancy.There are chromosomal abnormalities as a result of defects in the egg or sperm, or in connection with the temporary problems of division of the zygote.
Infectious diseases during pregnancy often lead to spontaneous abortion.This is especially acute infections that occur in the early weeks of pregnancy.Among infectious diseases flu takes an important role, which is the most common.Pregnancy often comes at an infectious hepatitis, acute rheumatism, with rubella, scarlet fever, measles.Miscarriage can happen with angina, pneumonia, pyelonephritis, appendicitis.Termination of pregnancy with acute infectious diseases contribute to high fever, intoxication, hypoxia, malnutrition and other disorders;in decidua produced degenerative changes, and hemorrhage;weaken the barrier properties of the chorionic and microorganisms can ente
Chronic infections can also contribute to abortion.In toxoplasmosis, tuberculosis, brucellosis, syphilis abortion occurs much less frequently than in acute diseases.When the full treatment of chronic infectious diseases can not save the pregnancy and she is developing normally.
Chronic noncommunicable diseases can also cause miscarriage, especially in severe disease.Such diseases include: organic heart disease with circulatory disorders, chronic glomerulonephritis, and severe hypertension.Pregnancy may be interrupted in the event of severe diseases of the blood (anemia, leukemia).
infantilism among the most frequent prichinamsamoproizvolnogo abortion.If there infantilism functional failure of the endocrine function of the ovaries and other endocrine glands, it is often irritability and lack of uterine contraction internal os ..
For frequent causes of miscarriage include the neuro-endocrine diseases of the endocrine glands.Miscarriage often occurs in hyperthyroidism, gipotirioze, diabetes, diseases of the adrenal glands and ovaries.
intoxication often leads to death of the fetus and the miscarriage.The most dangerous is the lead, mercury, nicotine, benzene and other toxic chemicals.
When blood incompatibility of Rh factor spouses, the fetus may inherit the father's antigens.Antigens embryo (incompatible with parent) when the cross the placenta in pregnant, contribute to the formation of specific antibodies.Antibodies penetrate into the body and may cause fetal haemolytic disease which can cause fetal death.Most often, in this case, it might be re-interruption of pregnancy.This is due to the fact that the sensitization repeated pregnancy increases.
egg and sperm anomalies that occur before conception may also cause miscarriage.
For frequent causes of abortion are transferred piece abortion, giving rise to disorders in the endocrine and nervous system, chronic endometritis and other inflammatory diseases.When the expansion of the cervix during an abortion tool can damage the muscle fibers in the isthmic-cervical section of the cervix, which would entail cervical incompetence in which child bearing becomes problematic.
inflammatory genital diseases are common factors abortion.Since inflammation disturbed function or structure of the endometrium.The cause of miscarriage may be adhesions, cancer formation in the pelvis that impede normal growth of the pregnant uterus.
Women with unstable nervous system abortion can occur in strong mental traumas.Physical injuries - fractures, contusions, concussions - all of these factors can also contribute to miscarriage, in the case of infantilism, inflammatory diseases and other contributing abortion moments.
in spontaneous abortion, which arose as a result of actions of the factors described above, the final result is the same process - the enhanced contractile activity of the uterus.Ovum gradually peeled from the lining of the uterus and is pushed out of its cavity, causing cramping and uterine bleeding of varying intensity.Late miscarriage like over at birth (there is an opening of the cervix, waste amniotic fluid, the fetus is born, and then the placenta)
clinical picture of spontaneous abortion depends on the gestational age, the stage of the reasons which led to termination of pregnancy.
for abortion in the first trimester of pregnancy is characterized by a combination of pain and bleeding in the second trimester miscarriage has early signs of cramping in the lower abdomen, bleeding after the birth of the fetus is attached.Depending on the etiological factors that caused spontaneous abortion may be especially its clinical manifestations.
In the case of a long course of spontaneous abortion are often from the vagina into the uterus penetrate pathogens (staphylococcus, streptococcus), which lead to the development of infected abortion.
Another severe complication of spontaneous abortion have placental polyp.This is a complication that occurs when a delay in uterine residues placenta membranes, which germinate connective tissue and tightly attached to the wall of the uterus.Clinically it is manifested by long spotting.Treatment is carried out by scraping the uterine cavity.
With the threat of miscarriage patient hospitalized immediately.The hospital conducted a comprehensive treatment aimed at eliminating the main causes of miscarriage, as well as on the continuation of the pregnancy.
