A deficiency in folic acid during pregnancy can lead to severe consequences for the neonate. These can include: - Neural Tube Defects (NTDs): Conditions like spina bifida and anencephaly. - Low Birth Weight: Infants may be born underweight, increasing the risk of other complications. - Preterm Birth: A lack of folic acid can contribute to premature delivery, which comes with its own set of neonatal disorders.
