Two main causes of birth defects include genetic factors and environmental exposures during pregnancy. Genetic factors can involve one or more abnormal genes or chromosomes that affect a baby’s development. For example, Down syndrome is caused by an extra copy of chromosome 21. Environmental exposures, such as drinking alcohol, smoking, or taking certain medications during pregnancy, can negatively affect the baby’s development, leading to birth defects. It’s crucial for expecting mothers to have regular check-ups and avoid harmful substances.
