It is not always possible to determine what causes low levels of amniotic fluid. Oligohydramnios can be caused by a continuous leaking of amniotic fluid. It can also occur when the fetus has kidney failure. After about four months of pregnancy, the kidneys of a normal fetus will produce the amniotic fluid. If the fetus has kidney abnormalities, the amount of amniotic fluid may be too low.
Polyhydramnios is a condition in which there is too much fluid in the amniotic sac, the sac that holds the developing baby (fetus). This liquid is called amniotic fluid, and it surrounds the fetus throughout pregnancy. Polyhydramnios can be caused by:1  Problems with the baby's nervous system or gastrointestinal tract.2  Genetic disorders or birth defects. 3  Multiple pregnancy (twins or more). 4  It occurs in up to 5 out of 100 twin pregnancies.5  Diabetes.his liquid is called amniotic fluid, and it surrounds the fetus throughout pregnancy.
