Question
The test results show that the fetus has Down syndrome, and online information indicates that formaldehyde is harmful to pregnant women. Does formaldehyde cause abnormalities in the fetus?
Answer
Down syndrome, also known as trisomy 21 or mongolism, is a disorder caused by a chromosomal abnormality (an extra 21st chromosome). Affected children have distinct facial features such as widely spaced eyes, flat nasal bridge, and single palmar crease; they often have congenital heart disease and other malformations; growth and developmental disabilities are common, and their lifespan is shorter. Down syndrome is caused by chromosomal abnormalities rather than formaldehyde directly. However, pregnant women should avoid exposure to harmful substances like formaldehyde to ensure fetal health. For children diagnosed with Down syndrome, parents should seek professional medical help promptly, avoid using unverified medications, and provide the child with ample love and care to promote healthy growth.
