What is a normal AFI?
AFI between 5-25 cm is considered normal; median AFI level is ~14 cm from week 20 to week 35, after which the amniotic fluid volume begins to reduce.
AFI <5 cm is considered to be oligohydramnios..
What is normal AFI at 34weeks?
Increasing amniotic fluid levels Amniotic fluid levels vary throughout the different stages of pregnancy. During weeks 32–34, the amniotic fluid volume may increase to 800 milliliters (ml) or more. … A typical AFI score is 5–25 cm. An AFI score lower than 5 cm is too low, and doctors refer to this as oligohydramnios.
How many cm of amniotic fluid is normal?
A normal amniotic fluid index is 5 cm to 25 cm. Less than 5 cm is considered oligohydramnios, and greater than 2cm is considered polyhydramnios.
How can I increase my AFI at 37 weeks?
1. Drink more fluids. Anytime during your pregnancy, drinking a lot of water can make a huge difference. According to one study , hydration is very helpful for upping amniotic fluid levels in women between 37 and 41 weeks of pregnancy.
What is the normal AFI at 30 weeks?
From a median of 10.3 cm (range, 8.7-13.7, 5th-95th percentile) at 15 weeks’ gestation, the amniotic fluid index rose progressively to a maximum median of 14.0 cm (range, 4.0-18.6) at 30 weeks. The index then gradually declined to a median of 9.1 cm (range, 4.8-14.2) by 40 weeks’ gestation.
What is the normal AFI at 35 weeks?
An AFI between 8-18 is considered normal. Median AFI level is approximately 14 from week 20 to week 35, when the amniotic fluid begins to reduce in preparation for birth. An AFI < 5-6 is considered as oligohydramnios. The exact number can vary by gestational age.
Can Polyhydramnios affect baby?
Women with polyhydramnios may experience premature contractions, longer labor, difficulties breathing, and other problems during delivery. The condition can also cause complications for the fetus, including anatomical problems, malposition, and, in severe cases, death. Treatment aims to remove excess amniotic fluid.
Does Polyhydramnios mean big baby?
A larger than expected fundal height could be a sign of fetal macrosomia. Excessive amniotic fluid (polyhydramnios). Having too much amniotic fluid — the fluid that surrounds and protects a baby during pregnancy — might be a sign that your baby is larger than average.
What is a high AFI level?
A normal AFI ranges from 5 to 24 centimeters (cm) . The second is to measure the deepest pocket of fluid within the uterus. Measurements over 8 cm are diagnosed as polyhydramnios. The range depends on how far along you are in your pregnancy, as the fluid levels will increase up to your third trimester, then decrease.
What causes low AFI?
Various factors can contribute to low amniotic fluid in pregnancy, including: Your water breaking. The placenta peeling away from the inner wall of the uterus — either partially or completely — before delivery (placental abruption) Certain health conditions in the mother, such as chronic high blood pressure.
What is borderline AFI?
In a study done by Phelan et al borderline AFI is defined between 5 and 8 cm (8, 10, 11). Also, Gumus and Miller have defined a borderline AFI as an AFI of 5.1-10 (12, 13).
What birth defects are associated with Polyhydramnios?
Persistent polyhydramnios has been associated with fetal aneuploidy,7 and polyhydramnios at birth has been associated with preterm delivery, unstable lie, malpresentation,4 cord prolapse, and placental abruption.

What happens if AFI is low?
Most women diagnosed with low amniotic fluid in the third trimester will have a completely normal pregnancy. If there are very low levels of amniotic fluid for your baby to float around in, there is a slight risk of intrauterine growth restriction and umbilical cord constriction during birth.
How is AFI calculated?
To calculate the amniotic fluid index (AFI), the anteroposterior diameters of the largest empty fluid pocket (no umbilical cord or fetal parts) in each quadrant are added together. The AFI is normally 7 to 25 cm. In addition, each individual pocket of fluid should be 2 to 8 cm.
