There are a variety of dangerous problems encountered during pregnancy, what are the causes of overd

Progesterone imbalance, fetal malformations, genetic factors, cephalopelvic disproportions, endocrine disorders, fetal enlargement, etc., can all cause such phenomena. Therefore, it is important to see a doctor in time and never ignore this problem to avoid fetal asphyxia.

Endocrine disorders, fetal enlargement, fetal malformations, or genetic factors, so when there is an overdue pregnancy, it is necessary to immediately go to the hospital for a detailed examination and timely induce labor.

The most common causes of post-term pregnancy are lack of outdoor exercise and exercise, prolonged sedentary care, polyhydramnios, and the fetus not entering the pelvis. Placental calcification, aging of the placenta.

The reason is that the development of the fetus is relatively abnormal or there is a secretion disorder, and the pregnant woman exercises for a short time in the late stage, and the amount of intake in the body is particularly small, so it will cause the fetus's head to be very large, and there is no way to put it in the basin, so it leads to a very long delivery time, and the lack of contractions will cause overdue pregnancy.

It may be caused by an irregular diet, or because of eating some cold food, or because of intense exercise, or emotional instability, or because of endocrine disorders, or because of a family history of genetic diseases, or because of very low nutrient intake.

It is very likely that it is because of one's own physical reasons or the external living environment, as well as the mood in life will intervene in some situations during pregnancy.

It is likely to be caused by a disproportionate head and pelvis, or it may be due to a malformed fetus, it may be due to a genetic disorder, or it may be due to a lack of sulfatase, or it may be due to estradiol.

1.Asymmetry of the cephalic pelvis of the body, 2Fetal malformations, 3Polyhydramnios, 4The placenta lacks one component, sulfatase, 5It may be that the hormone secretion in the body is insufficient, 6The genetic inheritance of the body and other reasons.

The causes of post-term pregnancy include abnormal hormone secretion, too little nutrition, too small uterine opening, asymmetrical cephalopelvis, too much amniotic fluid, and so on.

1.May be due to uterine atony and insufficient release of oxytocin receptors; 2.It may also be because the fetus is not mature, although the time has come, but it may be caused by the immaturity of the fetus on its own; 3.

It may also be caused by an imbalance in the ratio of estrogen and progesterone in the body.

Post-term pregnancy can easily cause the fetus to have hard bones and pass through the birth canal better without collapsing. It can also easily lead to an increase in the head cleft of the fetus. This can cause the fetus to develop into macrosomia.

It can also easily lead to oligohydramnios and intrauterine fetal asphyxia. The placenta calcifies. Newborn babies are prone to intracranial hemorrhage, neonatal pneumonia, or acidosis at birth.

Post-term pregnancy refers to the regular menstrual cycle of Lu Yun, and the pregnancy has reached or exceeded 42 weeks before delivery. Post-term pregnancy is unfavorable to both mother and child: the main effects on perinatal infants are fetal leakage syndrome, fetal distress, meconium aspiration syndrome, neonatal asphyxia and macrosomia, etc., and the morbidity and mortality of perinatal infants are significantly increased; The main impact on the maternal body is the prolongation of labor and the increase in the rate of dystocia, which significantly increases the surgical yield rate and maternal birth trauma.

It is a condition of pregnancy abnormality. The gestation is longer than 42 weeks. It may be that there is a problem with the hormone level, that the head of the fetus is relatively large, that the fetus is not in the pelvis in time, that there may be an endocrine disorder, or that the fetus is developing abnormally.

It may affect the child's health, it may cause the child to suffocate, it may affect the child's IQ.

It refers to a physiological reaction, the gestation time is more than 42 weeks, but the incidence of no birth is about 5%; It may cause the child to suffocate, it may cause the child to have a difficult birth, it may lead to insufficient estrogen secretion, and it may increase the risk of pregnancy.

The harm of overdue pregnancy is that it may lead to the death of the fetus, may lead to the miscarriage of the fetus, will cause stillbirth, and may also cause abnormalities in the pregnant woman's body, which will lead to the inability to conceive in the pregnant woman's body.

Normally, women should give birth at about 40 weeks of pregnancy, if the pregnancy time is more than 40 weeks, it means that there is an overdue pregnancy, overdue pregnancy has an impact on the pregnant woman and the fetus, so when there is an overdue pregnancy, what are the complications that are often accompanied? Let's take a look.

1. Overdue pregnancy usually has too little amniotic fluid, generally after 38 weeks of pregnancy, the amniotic fluid will gradually decrease, and it will be more obvious after 40 weeks, which reflects the function of the placenta in the uterus and shows that the meconium has been seriously polluted, if the newborn inhales these contaminated meconium will be prone to syndrome, and may be compressed by the umbilical cord.

2. Post-term pregnancy may also lead to intrauterine distress of the fetus in the womb, because the placenta of post-expiration pregnancy will definitely gradually degenerate, and the function will also decline, so the umbilical vein of the fetus, the oxygen saturation in the blood will definitely decline, so the oxygen and nutrition that can be supplied to the fetus will be less and less, and the fetus of post-term pregnancy will become more and more mature, and the worse the tolerance to hypoxia, it is easy to cause the fetus to be embarrassed in the uterus, and even die in the womb.

We all know that the placenta in the womb is the only way to provide oxygen and nutrition to the fetus, if it exceeds a certain time limit, the function of the placenta will degenerate in all aspects, which will directly affect the nutrition of the fetus and the lack of oxygen supply. The fetus may have intellectual disability due to the lack of oxygen and nutrient supply, which may affect the development of the nervous system.

All in all, if there is a post-term pregnancy, you should go to the hospital in time and give reasonable advice by the doctor, because the post-term pregnancy not only has a certain impact on the pregnant woman or the fetus, but also increases the rate of dystocia, but also increases the fetal mortality rate.

The complications that are often accompanied by a particularly low amount of amniotic fluid, as well as fetal intrauterine distress, of course, will also be accompanied by fetal hypoxia or fetal death in utero, it may be that the umbilical cord is compressed or the newborn is infected, which are all possible.

Cloudy amniotic fluid, unidentified discharge, irregular bleeding, abdominal distension, kidney infection, gastrointestinal disorders.

The fetus will be large, sometimes with reduced subcutaneous fat, which may cause fetal asphyxia, may cause **folds, can lead to miscarriage, and may lack vernix fat.

Oligohydramnios, fetal intrauterine problems, fetal growth restriction, can easily lead to macrosomia, and can easily lead to problems with the child's growth.

This is mainly due to the imbalance of estrogen or progesterone, and there are also factors of fetal inheritance; It is necessary to accurately verify the pregnancy roughness and week, and to calculate the budget period, and to make active treatment for pregnant women who are more than 41 weeks pregnant, which can effectively avoid overdue pregnancy.

It may be caused by an oversized or irregular fetus; Pregnant women should go to the hospital for regular check-ups and follow the doctor's advice.
