The risks associated with oligohydramnios often depend on the gestation of the pregnancy. (americanpregnancy.org)
If the measurement of amniotic fluid is too low it is called oligohydramnios. (americanpregnancy.org)
If an AFI shows a fluid level of less than 5 centimeters (or less than the 5th percentile), the absence of a fluid pocket 2 - 3 cm in depth, or a fluid volume of less than 500mL at 32 - 36 weeks gestation, then a diagnosis of oligohydramnios would be suspected. (americanpregnancy.org)
