Every 20 minutes, 1 Down's children are born. How can pregnant women avoid giving birth to Tang Bao with mental retardation?

There is such a baby, in the embryonic stage, the embryo has one more chromosome 2 1 than others. After birth, their faces are similar: the distance between the eyes is wide, the nasal root is low, the eye fissure is small, the outside of the eye is inclined, there is epicanthus, the external ear is small and the growth position is relatively low, and the tongue often sticks out. In terms of growth and development, their growth and development speed is much slower than that of normal people. They are short stature, short limbs, late teething, and their motor development and language development obviously can't keep up with normal children of the same age. So there is another name for this disease, called congenital idiot. They are also called Down's children or Tang Bao. ?

Every 20 minutes, 1 Down's children are born. How can pregnant women avoid giving birth to Tang Bao with mental retardation? In China, a Tang baby is born every 20 minutes on average. Even if it seems that their parents are healthy, their mothers may give birth to children with Down syndrome. In addition to mental retardation, their immunity is also very low, and a small cold will be very troublesome. If children with Down's syndrome live to adulthood, they will develop symptoms of Alzheimer's disease after the age of 30, and many of them are accompanied by organ abnormalities. For ordinary families,

So, what factors make it easy for pregnant mothers to give birth to Tang Bao?

1, age. Although young pregnant mothers will also give birth to Tang Bao, older pregnant mothers are more likely to give birth to Tang Bao. This is because after women reach the age of 35, the ovarian function will decline, and the quality of eggs will also decline and age, which will lead to problems in meiosis of eggs and affect the quality of fertilized eggs. Studies have shown that for pregnant mothers aged 20 to 40, the birth risk of Down's baby has increased from11530 to110 or even higher. Therefore, in order to avoid giving birth to Down's baby, pregnant mothers had better get pregnant before the age of 35.

2. heredity. Down syndrome is a chromosomal disease, so it also has a certain genetic tendency. If someone in the family has ever given birth to a Down's baby, the chances of a pregnant mother giving birth to a Down's baby will also increase. If such pregnant mothers don't give birth to Down's baby, they must have regular checkups during pregnancy, such as nt examination (1 1- 13 weeks transparent scan of the back of the fetus's neck) and.

3. Living habits. Living habits will also affect the health of the next generation. There is no doubt that from the beginning of pregnancy, both husband and wife should establish good living habits, avoid contact with radioactive radiation, toxic and harmful substances, ban smoking and alcohol, and avoid viral infection and chromosome damage during pregnancy.

In short, although we can't directly predict whether a baby is a Down's child, with the development of science and technology, pregnant mothers should pay more attention during pregnancy and have regular pregnancy examinations, which can also effectively reduce the chance of birth of Down's child!
