Amniotic fluid is an important factor in maintaining the development and survival of the fetus in the womb. In case of low amniotic fluid or too much amniotic fluid, there are potential risks to the fetus. So what is the average amniotic fluid?

1. What is amniotic fluid?

Amniotic fluid is a thin, pale yellow fluid that surrounds the fetus, which is important for the safe development of the fetus during pregnancy. Amniotic fluid will help the fetus move freely in the womb, allowing the baby to develop comprehensively according to human body standards.

Thanks to this fluid, the baby's lungs develop and the baby's temperature is always stable. Amniotic fluid also helps the baby to be safe from influences from outside the womb.
Amniotic fluid in each pregnant woman will be different and increase and decrease differently in each pregnancy period. Normally, when the fetus is 37 weeks old, the amniotic fluid reaches approximately 1000 ml. In many cases, a pregnant woman has too little or too much amniotic fluid (lack of amniotic fluid or polyhydramnios). Both of these conditions pose potential risks to the fetus.

2. What is the normal amniotic fluid index?

Amniotic fluid index (symbolized as AFI) is an indicator of the amount of amniotic fluid in the womb of a pregnant woman at each stage of pregnancy. Based on this amniotic fluid index, the doctor will let the mother know whether the fetal amniotic fluid status is normal or not, whether there is a shortage or polyhydramnios.
Normally the amniotic fluid index by week of the fetus will be as follows:
20 weeks old, the amount of amniotic fluid is about 350ml. At 25 - 26 weeks of age, the amount of amniotic fluid is 670ml. 32 - 36 weeks of fetal amniotic fluid is about 800 ml or more. Between 40 and 42 weeks amniotic fluid will decrease to about 540-600 ml. This is the time to give birth, monitoring amniotic fluid at this time is extremely important to help diagnose the health of the fetus. Based on the index of fetal amniotic fluid below, pregnant mothers can know if their baby is having a normal level of amniotic fluid or not. The level of amniotic fluid needs special attention.

3. What to do in case of low amniotic fluid or polyhydramnios?

With the above index, surely pregnant women already know what is normal fetal amniotic fluid and potential dangers when there is abnormality in amniotic fluid. So what to do when lack of amniotic fluid or polyhydramnios?
For pregnant women with a lack of amniotic fluid, mothers need to maintain a reasonable diet. Combine comfortable rest and avoid strenuous work. Pregnant women need to drink a lot of water and eat a lot of fruit to limit the risk of amniotic fluid deficiency during pregnancy. Supplementing amniotic fluid by drinking coconut water is popularly applied by mothers, while helping to make amniotic fluid clearer.

In case of mild polyhydramnios, there is no need to intervene but just wait for the full term fetus if there is no other indication from the doctor. In case of acute polyhydramnios, amniocentesis will usually be done to relieve respiratory symptoms for pregnant women. This is a temporary measure. If the fetus has a structural malformation or a chromosomal abnormality, the doctors will offer options to choose from, including termination of the pregnancy.
Lack of amniotic fluid or polyhydramnios seriously affects the health of the fetus and pregnant mother. Therefore, regular prenatal check-ups are extremely important during pregnancy. Regular check-ups and accurate diagnosis and advice from a doctor will help detect early signs of abnormalities in the fetus.
