1、 The risks to the health of mothers and babies caused by the increase of childbearing age
With the growth of age, women's fertility will gradually decline, especially after the age of 35, the quality and quantity of eggs will decrease, which is likely to lead to increased risk of infertility or abortion.
First of all, the elderly birth of second child will increase the risk of hypertensive disorder complicating pregnancy. The blood pressure of elderly pregnant women is easy to rise, which will lead to the occurrence of eclampsia, which is harmful to both mother and fetus.
Secondly, older pregnant women have a higher risk of gestational diabetes. With the increase of age, the function of female islets gradually weakens, which is easy to lead to abnormal blood sugar. In addition, the change of maternal metabolism increases the incidence of gestational diabetes.
In addition, older pregnant women may face more postpartum hemorrhage problems during childbirth. With the increase of age, the elasticity and contractility of the uterus will be weakened, which is likely to increase the risk of bleeding after childbirth.
2、 Older pregnant women are more likely to have fetal malformations and chromosomal abnormalities
The risk of older pregnant women giving birth also includes the increased probability of fetal malformations and chromosomal abnormalities. With the increase of age, the quality of female eggs decreases, and the possibility of abnormal chromosome number or structure of fertilized eggs will increase.
The most common type of chromosome abnormality is Down syndrome, and the risk of Down syndrome in elderly pregnant women will also increase with age. Children with Down syndrome will face mental retardation and physical retardation.
In addition, babies born to older pregnant women are more likely to have congenital heart disease, cleft lip, spina bifida and other fetal malformations. These problems will not only bring inconvenience to children's lives, but also require long-term treatment and care.
3、 Increased risk of complications during pregnancy
Due to the decline of their own physique, elderly pregnant women are prone to complications during pregnancy, which pose a threat to the health of mothers and infants.
For example, pregnant women are prone to anemia during pregnancy. Due to the effects of metabolic and physiological changes, the number of blood cells in pregnant women has decreased, resulting in anemia. Anemia in pregnant women can lead to fetal hypoxia, growth retardation, and even premature delivery.
In addition, elderly pregnant women are also prone to pregnancy with hysteromyoma or adenomyosis, which will increase the risk of miscarriage and premature delivery.
In addition, older pregnant women are also prone to depression during pregnancy. Due to changes in the endocrine and nervous system of the body, pregnant women's emotions tend to fluctuate and depression symptoms appear, which will have a negative impact on the growth and development of the fetus and the emotional relationship between mother and baby.
4、 Older pregnant women face more difficulties in pregnancy monitoring and postpartum recovery
Compared with young pregnant women, older pregnant women need closer pregnancy monitoring and longer postpartum recovery.
In terms of pregnancy monitoring, older pregnant women need more frequent prenatal examinations, including prenatal ultrasound examination, Down's screening, etc. This will increase the consumption of medical resources and put pressure on the supply and demand of social medical resources.
In terms of postpartum recovery, the physical recovery of older pregnant women will be slower than that of younger pregnant women. Due to the decline of physical function of elderly pregnant women, it takes longer and more energy to restore physical strength and energy. This will bring a certain burden to the family and society of elderly mothers.
Summary:
The risks to mothers and infants in the second child delivery at an advanced age are mainly reflected in the risks to the health of mothers and infants with the increase of the childbearing age, the increased risk of fetal malformations and chromosomal abnormalities in the elderly pregnant women, complications in pregnancy, and more difficulties in pregnancy monitoring and postpartum recovery faced by the elderly pregnant women. For couples who are going to have a second child at an old age, these risks should be carefully considered, and comprehensive inspection and monitoring should be carried out under the guidance of doctors to ensure the safety and health of mother and baby.
