Nowadays, as the pace of life becomes faster and faster, the competition becomes stronger and stronger, and the number of professional women also increases day by day, unknowingly slowing down the pace of starting a family and giving birth to a child, and when everything is as perfect as planned and all is ready, it seems to be farther and farther away from the “optimal conditions” for pregnancy and childbirth. There are also some women who, for various reasons, have had repeated brushes with their baby’s destiny, and when they finally meet their baby, the time is unforgivingly set at an advanced age. Of course, there are also the “Dinks” who are beginning to wander, and their desire to have a baby increases with age. In recent years, the liberalization of the two-child policy has also made many women in their thirties and forties to join the ranks of senior pregnant mothers …… pregnancy “life”, to grasp the timing. In the past, the age of 23, 25 years old as the standard of late marriage and childbearing, but now the vast majority of people are late marriage and childbearing. At present, the age of most pregnant women is 25 to 35 years old, and there are many pregnant women who are already over 35 years old. Medically, pregnant women over 35 years old are called high-age pregnant women. Among them, China’s high-age pregnant women account for about 11.5%, and there is a rising trend. Crossing into the ranks of high pregnant women, in the road to mother and child safe pregnancy, easy to encounter which stumbling blocks? One of the obstacles: difficult to conceive Medical research has found that both men and women, fertility will gradually decrease with age, the ideal age for women to have children is 25 to 30 years old, and when you choose to get pregnant at the age of 35, the physiological functions of your body will decline to varying degrees, and your ovaries will decline in function, and your estrogen level will be low, so your chances of getting pregnant will also decrease significantly. In addition, these older women will have psychological fear, nervousness, anxiety, pessimism, shyness, depression and other negative emotions. These bad moods will lead to ovarian endocrine disorders, irregular ovulation, or even no ovulation, and menstruation will begin to be disorganized or amenorrhea. In this case, of course, it is not easy to get pregnant. In addition, with age, gynecological diseases also begin to increase, which is also one of the factors causing difficulty in conception. Detention No. 2: Miscarriage As age increases, women’s reproductive capacity decreases year by year, and immunity is weakened, and the miscarriage rate of pregnant women of advanced age increases significantly. According to statistics, the abortion rate of 25-30-year-old pregnant women is 15%, while after 40 years of age is as high as 40%. The main reasons are: (1) normal women have to discharge more than 300 mature eggs in their lifetime, with the increase of age, the harmful factors affecting ovarian function are increasing, such as radiation, pathogenic microbial infections and inflammation, etc., which directly lead to the decline of female ovarian function, and the quality of discharged eggs is also declining year by year. The decline in the quality of eggs will lead to a decline in the quality of fertilized eggs, which in turn will sow the seeds of miscarriage. (2) Due to the advanced age of pregnant women themselves, the increase in age, resulting in human genetic material, very easy to occur aberrations or genetic material abnormalities, which is also the advanced age of pregnant women prone to miscarriage. (3) Due to the increase in age, gynecological diseases also begin to increase, in addition to the inflammation of the uterus itself, the incidence of uterine fibroids endometritis and uterine polyps also increase. In addition, it is also easy to have some medical and surgical comorbidities, such as hyperthyroidism, or chronic hypertension, diabetes and other medical and surgical diseases. These diseases are all triggers for miscarriage. Detention of the third: fetal dysplasia According to statistics, elderly pregnant women fetal dysplasia and the chance of malformation significantly higher. First of all, due to the ovaries and testes with age gradually aging metamorphosis, they produce eggs and sperm also natural aging, metamorphosis, chromosomal aberrations increase the opportunity to be fertilized by such eggs (or sperm) developed into a fetus, its deformity and the incidence of certain genetic disorders will increase, miscarriage, preterm labor, stillbirth, deformity and dementia of the child’s incidence is also very high. Secondly, due to placental dysplasia or aging of the placenta, the blood flow supplying the embryo and even the fetus is reduced, and the lack of nutrition of the fetus will cause retardation of fetal development or malformation, and the death of the fetus. Furthermore, women of advanced age tend to suffer from gynecological or internal diseases, such as uterine fibroids, ovarian cysts, irregular menstruation, primary hypertension, etc., which also have a certain impact on the development of the fetus. In addition, pregnancy complications such as hyperemesis gravidarum, cerebrovascular accident, renal failure, liver function abnormality, etc. may also cause preterm labor, fetal developmental delay and low fetal weight. The fourth obstacle: pregnancy complications of pregnant women of advanced age have more complications than young pregnant women, the most common are pregnancy heart disease, gestational hypertension syndrome, gestational diabetes and so on. During pregnancy, the blood volume of the pregnant woman’s body than non-pregnancy increased significantly, the burden on the heart increased, many pregnant women with heart disease can not tolerate, and had to terminate the pregnancy in advance; gestational hypertension syndrome is a disease unique to pregnancy, manifested as hypertension, proteinuria, edema, severe convulsions, coma, cardiac and renal failure, and even maternal and infant mortality; in addition, the metabolism of pregnant women’s bodies can not be used to determine whether a pregnant woman is pregnant or not, but the indicators of diabetes, the most common complications of pregnancy. The indicators of diabetes can not be used to determine whether the pregnant woman is diabetic. Gestational diabetes is very harmful, it not only makes the mother susceptible to infection, but also can cause preterm delivery, macrosomia, malformed fetus, stillbirth, and is one of the main causes of neonatal death. Detention No.5: High risk of delivery Due to age, the delivery process of senior mothers will have more difficulties than those who are 10-20 years younger. 10% of senior mothers will deliver prematurely, and the labor process is longer than normal, which is prone to haemorrhage and obstructed labour. Cesarean section is more common among older women because of the deterioration of pelvic and ligament function, weakened elasticity of the soft birth canal tissues, correspondingly weaker uterine contractions, and the cervix is generally tougher, making natural delivery more difficult. Although cesarean section is a better method for senior pregnant women, but the trauma it brings is also very heavy, the time needed for recovery is longer than natural normal delivery, and it will increase the chances of maternal infections, there are anesthesia accidents, amniotic fluid embolism and the possibility of hemorrhage during labor, and postpartum is also prone to endometriosis, pelvic inflammatory disease, and so on. Therefore, advanced age is not a necessary condition for cesarean section, and you should follow your doctor’s advice and arrangement according to the specific situation.
