Amniotic fluid is derived from the amniotic fluid, fetus and the mother body. And if you get any abnormalities from the amniotic fluid, it is dangerous.

Low amniotic fluid can seriously affect the health of the fetus, so it is essential to identify the cause of this condition early to make appropriate treatment options.
What is the role of amniotic fluid?
Amniotic fluid has a vital role in the life and development of the fetus. It is the perfect environment for the baby thanks to the rich nutrition, ability to regenerate and strong exchange.
In the early stage of pregnancy, it helps to nourish the embryo. During the growing of the fetus, the amniotic fluid has the effect of protecting the fetus from bumps, traumas, infections and helping the fetus to develop harmoniously balance.
During labor, the amniotic fluid helps the mother’s cervix to open well, the vaginal lubrication in the amniotic fluid helps the fetus release more easily.
What is the average amniotic fluid level?
Under normal conditions of pregnancy, amniotic fluid volume of 10 weeks after pregnancy is about 30ml. And it is about 1000ml in the weeks 34th to 36th. After 40 weeks, it will reduce to 800ml.
In some cases, the volume of amniotic fluid will be significantly reduced, even to 5-10ml. And it will cause amniotic fluid deficiency or low amniotic fluid (Oligohydramnios). If the ultrasonography concludes that the amniotic fluid index measured in 4 amniotic fluid compartments is less than 5cm in the last three months of pregnancy, it is called Oligohydramnios.
How to know if amniotic fluid is low or not?
When the amniotic fluid is lacking, the mother often does not have any apparent symptoms. You can only feel the movement of the fetus reduces, and your abdomen does not enlarge. And there are the following levels of amniotic deficiency:
- Medium amniotic fluid deficiency: amniotic index of 5-7 cm
- Severe amniotic lack: amniotic index of 3-5 cm
- Amniotomy: amniotic index less than 3 c
The assessment of amniotic weakness is closely related to the health prognosis of the fetus. If you got an amniotic deficiency in the first three months, the risk of miscarriage is up to 80%. If you are lack of amniotic fluid in the middle three months, the fetus has a high risk of congenital disabilities. And in the last three months, the embryo will get malnutrition.
Low amniotic fluid, what to do?
In the first three months
There is no specific treatment for this case. The optimal method now is to try to keep the fetus developing for more than 35 weeks, by advising the woman to lie on her left side, to control the accompanying conditions. Besides, you should provide adequate nutrition to improve uterine circulation. If you get a severe amniotic deficiency, you should consider terminating the pregnancy if it comes from the mother or the embryo.
In the middle three months
In this case, you should find out the reason for the situation, especially the pathology of the fetal urinary tract aplasia. Once the risk of major malformations and severity is determined, you should choose to terminate the pregnancy.
In the last three months
Pregnant women need to lie down, drink an average of 3 liters of water a day or need to be hospitalized for infusion to increase blood flow to the uterus. Pregnant women also need to measure the amniotic fluid index 1-2 times/ week regularly.
