High risk of Down syndrome screening for second child

Some women feel that they have experience after getting pregnant with their second child, so they think many prenatal checkups are unnecessary, and they even don’t do Down syndrome screening. This situation is very dangerous. It is still very common for second-born babies to be at high risk for Down syndrome screening, so this test is a must. Through Down syndrome screening, we can identify many aspects of the disease so that pregnant women and their families can prepare in advance and avoid adverse consequences in the future.

Every prenatal checkup is like a hurdle for expectant mothers, and they breathe a sigh of relief after passing one. Down syndrome screening is one of the necessary examination items in prenatal check-up, but many pregnant women cannot pass the Down syndrome screening. On the one hand, the accuracy rate of Down syndrome screening is only 60%, and on the other hand, the number of women with late pregnancy is increasing, especially for second-born babies at an advanced age, high risk of Down syndrome screening is more common. The specific cause of Down syndrome is still unclear, but the older you are, the higher the chance of developing Down syndrome. This is a probability number derived from the data. Therefore, generally speaking, doctors will recommend that pregnant women with their second child who are over 35 years old do another amniocentesis or non-invasive DNA screening.

It should be particularly noted that Down syndrome is a sporadic disease. It is not something that you will get at an older age but not at a younger age. Regardless of whether you are old or young, as long as the Down syndrome screening result is high risk, further examination is recommended. The specific choice of which option to choose can be based on the doctor's advice.

During pregnancy, you can prevent the common causes of Down syndrome and reduce the risk of Down syndrome screening

1. Genetic genes: There is a risk of inheritance of Down syndrome. If there is a history of Down syndrome in the family, you must be careful during pregnancy. You must go through every checkup during pregnancy, including Down syndrome screening, amniocentesis, and non-invasive testing.

2. Radiation: Pregnant women should stay away from radiation as much as possible during pregnancy. If you are an older pregnant woman, you must be more cautious. In addition to using less low-radiation household appliances such as mobile phones, computers, refrigerators, and microwaves, you must stay away from large high-radiation equipment such as medical equipment, electronic instruments, and copiers.

3. Medicines: Taking medicines indiscriminately will also increase the risk of Down syndrome. You must not take medicines indiscriminately during pregnancy. Do not take it for granted that you can take a certain medicine. It is safest to follow the doctor's advice. Otherwise, be careful that you will be at high risk of Down syndrome.

4. Pregnancy check-up: Pregnancy check-up is not only a result, but also the best means of prevention. It can let you know all the situations during your pregnancy. Professional doctors will also give you the most professional advice, so you can’t take chances and must do every prenatal check-up.

5. Pesticides: In daily life, you must stay away from pesticides and other chemical drugs. Fruits and vegetables must be washed thoroughly. Chemical residues will also increase the risk of Down syndrome. Pregnant women living in rural areas should pay special attention.
