While not all fetal anomalies can be prevented, certain measures can reduce the risk of occurrence: - Prenatal Care: Regular prenatal visits can help monitor and manage potential risks. - Folic Acid Supplementation: Taking folic acid before conception and during early pregnancy can prevent neural tube defects. - Avoiding Teratogens: Pregnant women should avoid exposure to harmful substances like alcohol, tobacco, and certain medications. - Vaccinations: Immunizations against infections like rubella can prevent related fetal anomalies.
