A good pregnancy test does not guarantee that a child with intellectual disability will not be born, for example, fetal malformations that cannot be detected by the test program, lack of oxygen during delivery, and complications after preterm delivery may all lead to the occurrence of children with intellectual disability.
1. Fetal malformations that cannot be detected by obstetrical examination: Obstetrical examination during pregnancy is only a screening test, even if all the obstetrical examination items are normal, there are still fetal malformations that cannot be detected by obstetrical examination, which may lead to the birth of mentally retarded children.
2. Lack of oxygen during labor: Fetal oxygen deprivation during labor can be caused by weak uterine contractions, umbilical cord wrapping around the neck, etc., resulting in neonatal ischemic-hypoxic encephalopathy, which leads to the occurrence of mentally retarded children.
3. Complications after preterm labor: It can be due to extreme preterm labor and other reasons, resulting in too many postnatal complications, such as intracranial hemorrhage, leading to the emergence of mentally retarded children.
If you are pregnant, it is recommended that you go to a regular hospital, go to the labor and delivery checkups on time, and deal with any abnormalities in a timely manner.
