How is congenital disease caused

summary

Maybe there are some people around us because they were born with some congenital diseases, so how is this congenital disease caused? Let's understand.

How is congenital disease caused

First of all, if there are other people in the family who have the same disease, and the age of onset is similar, it may be a genetic disease. So before giving birth to a child, it's better for both sides to know if there is such a genetic history in the family.

Secondly, congenital abnormalities can also be seen in women before pregnancy and early pregnancy, lack of folic acid in the body, will lead to spina bifida and anencephalia increased birth risk. Breech delivery and pregnancy age is too old, often lead to congenital dislocation of the hip and mental retardation.

Finally, the genetic material in our body contains 100000 pairs of genes, and each person has more or less a few bad genes. These bad genes are usually hidden, only when the couple's bad genes happen to be the same gene match, the child will get sick. Because this possibility is very small, the incidence of this kind of recessive genetic disease is only less than one in tens of thousands. If close relatives get married, couples are likely to have the same bad genes, and the possibility of these genes pairing increases dozens of times, or even hundreds of times. Therefore, the rarer the genetic disease, the greater the proportion of children born to close relatives. Although Chinese Han people prohibit cousins of the same surname from getting married, they do not prevent cousins of the opposite sex from getting married. In fact, from the perspective of genetics, cousins and cousins have the same degree of close relatives, and their children may suffer from various recessive genetic diseases after marriage.

matters needing attention

Prenatal examination is a method to prevent genetic diseases. It can be used for pregnant women who may give birth to children with certain genetic diseases. So before having a child, both sides must go to the hospital to have a check-up. In addition, the check-up during pregnancy is also very important.
