Three major causes of fetal chromosomal abnormalities, pregnancy do not ignore these three points, do effective prevention

Chromosomal abnormalities detected during pregnancy will be a very serious situation, as long as the existence of chromosomal abnormalities after birth will have genetic diseases. < / P > < p > at present, more than 100 kinds of chromosomal abnormalities related diseases can be identified, and dysplasia and mental retardation are their common manifestations. Therefore, once the fetal chromosomal abnormalities are found, the best way is to terminate pregnancy. < / P > < p > fetal chromosomal abnormalities caused by sperm chromosomal abnormalities; fetal chromosomal abnormalities caused by egg chromosomal abnormalities; although sperm and eggs are normal, but after the formation of fertilized eggs, chromosomal gene mutations caused by various factors make fetal chromosomal abnormalities. < / P > < p > in daily life, if you are often exposed to radiation, such as various X-rays, it is easy to cause chromosome abnormalities. Frequent exposure to various chemicals is also the cause of chromosomal abnormalities. < / P > < p > old age is also a high risk factor for chromosomal abnormalities.

If you are sick and pregnant, the probability of your baby’s chromosomal abnormalities will be much higher, which will more easily lead to your baby’s “deformity” and mental retardation. < / P > < p > in addition, during pregnancy, we must pay attention to the reasonable diet structure, balanced nutrition, adequate intake of vitamins and protein, additional folic acid, calcium, iron and other trace elements according to their own situation. < / P > < p > in daily life, we should keep away from all kinds of unfavorable factors that may cause chromosomal abnormalities, pay attention to the supplement of diet and trace elements, and at the same time, we should follow the doctor’s advice and do a good job in pregnancy examination. 08/16/2020
