Spontaneous abortion is the flow of the fetus out of the mother’s body before it is able to survive. Spontaneous abortion accounts for about fifteen to thirty percent of all pregnancies. A miscarriage in the first trimester is called an early miscarriage; a miscarriage between the twelfth and twentieth weeks of gestation is called a midterm miscarriage. A miscarriage after the twentieth week of gestation is called a premature miscarriage, and the fetus may survive, but it requires very advanced care.
Complex causes of spontaneous miscarriage
(1) Inadequate embryonic development
Abnormal pregnancy eggs are the main cause of early miscarriage. About 80% of the miscarriages in the first two months of pregnancy are due to some kind of defect in the sperm and eggs in order to cause the embryo to develop to a certain extent and terminate, therefore, the original embryonic tissue cannot be seen in the discharge of this miscarriage.
(2) Endocrine dysfunction
The fertilized egg can only be laid on the uterine wall and grow into a fetus under the action of progesterone. When there is insufficient secretion of progesterone in the body, the uterine meconium will be poorly developed, thus affecting the development of the fertilized egg and easily causing miscarriage. If prostaglandins increase, it will cause frequent contractions of the uterine muscles, which will also lead to miscarriage. A decrease in thyroid function can impair the oxidative capacity of cells, which in turn affects the growth and development of the embryo and leads to miscarriage.
(3) Diseases of reproductive organs
Uterine malformations such as bicornuate uterus, longitudinal uterus, and uterine dysplasia. Pelvic tumors, especially submucosal myomas, can affect the growth and development of the fetus and lead to miscarriage. Loose endometrium or deep cervical laceration can cause premature rupture of fetal membranes and late miscarriage.
(4) Systemic diseases of pregnant women
If a pregnant woman suffers from acute infectious diseases such as influenza, typhoid and pneumonia, bacterial toxins or viruses can enter the fetus through the placenta and cause fetal death by poisoning. High fever can promote uterine contraction and cause miscarriage. Pregnant women with chronic diseases such as severe anemia, heart failure, chronic nephritis and hypertension can cause miscarriage due to placental infarction and lack of oxygen in the uterus, which can disable the fetus. Malnutrition of pregnant women, especially vitamin deficiency, as well as mercury, lead and alcohol poisoning can cause miscarriage.
(5) Trauma
The abdomen of a pregnant woman is hit or squeezed by external force, and the pregnant woman falls or participates in heavy physical labor or strenuous sports; abdominal surgery such as appendicitis, or ovarian cyst surgery can cause uterine contraction and miscarriage.
(6) Rapid emotional changes
Pregnant women’s emotions are greatly stimulated, excessive sadness, fright, fear, and excessive emotional excitement can cause the internal environment of pregnant women to be dysregulated, prompting the uterus to contract and cause miscarriage.
(7) Placental dysplasia
The fetus grows and develops in the mother’s body, mainly through the placenta to transport nutrients and oxygen from the mother to the fetus, if the placenta is underdeveloped or diseased, the fetus will not receive nutrients and oxygen and stop growing, causing miscarriage.
(8) Mother and child blood type incompatibility
If a pregnant woman has received a blood transfusion in the past, or if a coagulant factor is produced during pregnancy that is incompatible with the blood type, it will cause the fetus to have coagulation and hemolysis of fine cells in the body, thus causing miscarriage.
Spontaneous miscarriage is not necessarily a bad thing, do not blindly keep the baby
Many pregnant women don’t know much about the causes of spontaneous miscarriage, so no matter what the cause of the miscarriage is, they all ask for birth control and even blindly take birth control drugs. In fact, there are reasons for natural miscarriage. Early miscarriages, especially those that you do not notice, are mostly due to abnormal development of sperm or eggs, which can also be said to be caused by a bad “seed”, which is an important natural screening phenomenon. This is an important natural screening phenomenon. At this time, it is not advisable to preserve the pregnancy, and only minor symptomatic treatment is usually done. In fact, even if a few embryos are “lucky” enough to develop into a mature fetus and deliver normally, the rate of malformed or low energy babies will be greatly increased in this case.
”In the later stages of miscarriage, it is often caused by nutritional or external factors, such as uterine fibroids and a history of previous miscarriages, which require prompt and active intervention.” Therefore, the majority of pregnant women appearing miscarriage aura, should not blindly keep the fetus, is “preservation” or “flow” should follow the guidance of the doctor.
Several tests should be done after a spontaneous miscarriage
After a spontaneous miscarriage, especially after repeated spontaneous miscarriages, you should pay attention to it and do some tests in time to find the cause of the miscarriage so as to create conditions for the next pregnancy. After a spontaneous abortion, the following tests should be done.
The male partner’s semen: if the sperm is poorly mobile and has a high rate of malformation it will affect the combination of sperm and egg. Defective sperm will often result in miscarriage even if they are able to unite with the egg.
Female ovulation and luteinizing hormone function: you can see some problems from the basal body temperature measurement chart. If the basal body temperature climbs slowly after ovulation and the high temperature is maintained for a short period of time, it indicates poor luteinizing hormone function and a tendency to miscarriage. In addition, menstrual irregularities due to problems with the gonadal axis, not easy to get pregnant also prone to spontaneous abortion.
The uterus of the female partner: The uterus is the breeding ground for the growth of the fetus. If the uterus is small or has abnormalities, such as fibroids, it will restrict the expansion of the uterine cavity and affect the space for fetal development and cause miscarriage.
Chromosomes: If one of the parents is found to have abnormal chromosomes, the pregnancy should not be conceived or terminated in time.
In addition, the health of the female partner should be thoroughly examined. If you suffer from acute infectious diseases such as acute hepatitis and pneumonia during pregnancy, bacterial toxins or viruses can enter the blood of the fetus through the placenta and cause fetal death due to toxic infection, or if the female partner suffers from more serious chronic diseases such as chronic hepatitis and hyperthyroidism, it can also disrupt the endocrine system and cause fetal miscarriage due to placental ischemia and hypoxia.
Spontaneous miscarriage has a precursor
Miscarriage is not a “congenital problem” as traditionally believed, in fact, 90% of spontaneous miscarriages can be prevented. The prevention of miscarriage relies on the pregnant woman being alert to various danger signs, as the number of hospital examinations for pregnancy is after all limited and early detection of problems is difficult. The following are abnormal signs in each stage of pregnancy that pregnant women should visit the hospital as soon as they become aware of them.
Aura in the first 3 months.
1. Pain in the lower back, which may be a tilted fetal position.
2. Sudden swelling of the legs, hands or feet, which may be due to high blood pressure or amniotic fluid.
3. Frequent headache, dizziness, blurred vision, which may be ectopic pregnancy or kidney failure.
4.Persistent or indirect abdominal pain may be ectopic pregnancy, fibroids or haematochezia.
5.Burning sensation in the urethra, cloudy urine or blood in urine, may be a kind of urinary tract infection called ting 1, which has great influence if left untreated.
6, unexplained red rash, harmful to both mother and fetus.
7. Chills and fever may indicate at least inflammation of the uterus, ranging from severe to ectopic pregnancy. A fever of 101 degrees Fahrenheit can jeopardize the pregnancy.
8. Bleeding or oozing blood is a precursor to miscarriage.
Aura within 4 to 6 months.
1. Weight gain of less than one pound per week indicates inappropriate fetal development.
2. No fetal movement in the 20th week, or sudden change in fetal movement.
The mother may feel very uneasy in the 6th trimester and may seek medical attention. Not all of the 6th trimester sensations are allergies.
Aura from 7 to 9 months
1. 4 or more contractions per hour before the 37th week is a precursor of preterm labor.
2. When no fetal movement or change in fetal condition is seen for more than 4 hours.
How to prevent spontaneous miscarriage.
1, within six months after the occurrence of miscarriage to contraception, to wait for six months after the pregnancy again, can reduce the occurrence of miscarriage.
2. Genetic examination should be done, and both spouses should be examined for chromosomes at the same time.
3.Do blood group identification including Rh blood group system.
4.Inside stitching can be done for those with loose endometrium.
5, for luteal insufficiency treatment of drugs to be used for a period longer than the duration of pregnancy of the last miscarriage (such as the last miscarriage in the third trimester, the treatment time can not be shorter than the third trimester).
6, have low thyroid function, to maintain normal thyroid function before pregnancy, and also to take anti-low thyroid drugs during pregnancy.
7, pay attention to rest, avoid intercourse (especially during the pregnancy period of the last miscarriage), emotional stability, regular and disciplined life.
8, the male partner should do the examination of the reproductive system. Those with bacteriospermia should be treated thoroughly before the wife conceives.
9, avoid exposure to toxic substances and radioactive material exposure.
10.The net working hours of computer work should be less than 20 hours per week.
11.After abortion, you should rest for four weeks, and it is not advisable to do sports now.
