What is habitual abortion?

　　Why do you always have miscarriages?？habitual abortion What is the reason? Behind the manifestation of habitual abortion, there is something hidden disease The most common causes are as follows:

　　Uterus Developmental abnormalities: Congenital uterine malformations such as bicornuate uterus, saddle-shaped uterus, undersized uterus, intrauterine adhesions, uterine fibroids, etc. can also cause habitual miscarriage. The uterus is the place where the pregnant egg implants, develops, and grows, and is the soil for embryonic development. Abnormalities in the uterus that prevent the normal development of the pregnant egg will lead to miscarriage, so it should be treated actively. Uterine dysplasia and small uterus can be treated with estrogen, and diethylstilbestrol 0 is commonly used. 5 mg to 1 mg, once a day, orally before going to bed, for 20 consecutive days starting from the 5th day of the menstrual cycle, for a total of 3 to 4 cycles; foreign body stimulation can also be used, such as placing a small IUD in the uterus to promote uterine enlargement; sometimes surgery is required, such as removal of intrauterine adhesions, uterine plastic surgery, fibroid removal, etc.

　　Genetic factors: In consanguineous marriage, one or both spouses have chromosomal abnormalities. The closer the blood relationship between the couple is, the easier it is for the next generation to have dominant chromosomal abnormalities. Embryos with chromosomal abnormalities are often unable to survive and lead to miscarriage, and some may have abnormal births, fetus Developmental delay, or dominant inheritance of chromosomal abnormalities despite survival.

　　Luteal insufficiency：Ovarian rupture After ovulation, the corpus luteum is formed, which secretes progesterone and estrogen. After conception, the corpus luteum continues to maintain pregnancy for 4 to 6 months before beginning to degenerate. The lifespan and function of the corpus luteum in early pregnancy are affected by chorionic gonadotropin (HCG). After the pregnant egg implants in the uterus, the syncytiotrophoblast differentiates from the egg embryo cells. The uterine decidua in contact with it will develop into the placenta in the future. The syncytiotrophoblast quickly secretes HCG into the mother's body, extending the life of the corpus luteum and stimulating it to synthesize progesterone to maintain pregnancy.

　　Blood type incompatibility between mother and child: The most common is ABO blood group incompatibility, and less common is RH type and MN system blood group incompatibility. If the blood types between mother and fetus are incompatible, the antigens obtained by the fetus from the father enter the mother's body to produce antibodies. The antibodies enter the fetal blood circulation through the placenta and act on red blood cells, causing them to destroy hemolysis. In severe cases, the fetus may die, leading to late miscarriage. In ABO blood type incompatibility, most pregnant women have type O blood and their husbands have type A, B or AB blood. If the fetal blood type is type A or B, late miscarriage may occur, but the incidence is not high.

　　Relaxation of the internal cervical os: Habitual late miscarriage is often caused by relaxation of the internal cervical os. Due to surgical injuries, a small number of congenital developmental abnormalities cause dilation of the internal cervical os and defects in the uterine isthmus. After the second trimester, the amniotic fluid increases, the fetus grows, and the intrauterine pressure increases. The fetal sac protrudes from the internal cervical os, and the cervical canal gradually shortens and expands. When the pressure increases to a certain level, the fetal membranes suddenly rupture, causing the fetus to be expelled and miscarried. For this kind of recurrent miscarriage, depending on the period of previous miscarriage, intrauterine orifice suturing can be performed at 12 to 20 weeks of pregnancy, followed by tocolysis treatment, and the sutures can be removed when there are signs of labor at full term or when a cesarean section is planned. 》》》》 How to give birth to a boy easily 8a habit

　　The causes of habitual miscarriage are complicated. Only by identifying the cause and providing targeted treatment can satisfactory results be achieved. Women suffering from this disease should go to Hospital Do a comprehensive system check. one stream Postpartum , especially women with ovarian dysfunction and uterine hypoplasia, it is best to go through 3 normal menstrual cycles before conceiving, so as to have enough time to restore hormones and endometrial function in the body.
