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.
Polyhydramnios is usually diagnosed when amniotic fluid volume reaches two litres (3.5 pints) or more (Carter 2012) . In severe cases of polyhydramnios, there may be as much as three litres (5.3 pints) of fluid, or three times the normal amount, around your baby.f other known causes have been excluded, and the extra fluid is thought to be due to your baby weeing too much, you may be prescribed a drug that reduces the amount of urine your baby produces (Carter 2012, Thomas and Knott 2011) .
