Polyhydramnios is defined as an AFI of greater than how many centimeters?

15 cm

20 cm

25 cm

Polyhydramnios is characterized by an abnormal increase in amniotic fluid volume, and it is specifically defined as an Amniotic Fluid Index (AFI) greater than 25 centimeters. The AFI is a measurement used to assess the amount of amniotic fluid surrounding the fetus during pregnancy. An index above this threshold indicates that the fluid is in excess, and this condition can be associated with various maternal and fetal complications, such as fetal anomalies, gestational diabetes, and preterm labor.

Understanding the AFI categories helps in identifying and managing polyhydramnios effectively, as well as recognizing its potential implications for the pregnancy and the health of the fetus. An AFI above 25 centimeters signals that further evaluation and monitoring may be needed, which plays a critical role in maternal-fetal medicine.
