Question
A 29-year-old pregnant woman was at the hospital for a check-up when her doctor mentioned Trisomy 21 syndrome, and she felt confused about it. What does Trisomy 21 syndrome mean?
Answer
Trisomy 21 syndrome, also known as Down syndrome, is a genetic disorder caused by the presence of an extra chromosome in the 21st pair. When the test results show a critical risk, this only indicates a certain level of risk, not that it will necessarily occur. Modern medical technology is quite advanced, and it is recommended to undergo amniocentesis or non-invasive DNA testing for confirmation. During pregnancy, attention should be paid to health care, balanced diet, consumption of fresh fruits and vegetables, and proteins, as well as regular prenatal examinations. In case of any abnormalities, an immediate revisit to the clinic is advised.
