Causes of polyhydramnios. 1  Polyhydramnios can sometimes mean that there is a birth defect or a medical problem. 2  Birth defects that affect the baby's ability to swallow and process amniotic fluid may cause polyhydramnios. Most of these birth defects are rare, but it is important to perform a detailed ultrasound to make sure there is no evidence of these conditions.
Birth defects or genetic disorders can also be caused by a problem with the number or structure of chromosomes. Usually this results in multiple body systems being affected. Approximately 1% of all babies will be born with chromosomal abnormality, which can cause physical problems and mental retardation. 2  More than 20% of infant deaths are caused by birth defects or genetic conditions (e.g. congenital heart defects, abnormalities of the nervous system, or chromosomal abnormalities).
