During pregnancy, women need to undergo examinations to understand the health status of the pregnant woman and the condition of the fetus, so various examinations are essential. And there are many essential examination items, such as screening for Down syndrome, which is a very important examination to prevent the birth of Down syndrome babies. So, how many types of Down syndrome are there?
Down syndrome is a very serious congenital disease, which can be divided into three types: standard type, translocation type, and chimeric type. Currently, there are few treatment methods for Down syndrome in medicine, and the results are not satisfactory. Prevention is still the main approach. So, after becoming pregnant, women must undergo Down syndrome screening.
If a pregnant woman has given birth to a Down syndrome baby before, she must undergo a check-up after becoming pregnant again, and the couple should also undergo a preconception test during pregnancy to minimize the chance of Down syndrome baby appearing. If there has been a history of Down syndrome in the family, the couple should increase their screening efforts. Even if Tang's son has not appeared in several generations, we cannot take it lightly. After pregnancy, women need to stay away from radiation sources. Radiation is ubiquitous in daily life, and pregnant women should not only stay away from it, but also wear radiation resistant clothing to prevent harm to the fetus due to radiation. In the prevention of Down syndrome, exposure to chemicals should also be avoided.
