What can deform a unborn child?

An unborn child can be affected by various factors that may lead to deformities, including genetic abnormalities, exposure to teratogens (substances that can cause malformations), infections during pregnancy (such as rubella or Zika virus), and maternal health issues (like uncontrolled Diabetes or substance abuse). Environmental factors, such as radiation or certain medications, can also contribute. Proper prenatal care and avoiding harmful substances can help reduce the risk of deformities.
