The amniotic fluid is decreasing

Amniotic fluid is a very important substance for the fetus and can provide protection for the fetus's survival. Some people have more amniotic fluid and some have less. The amount of amniotic fluid also has a certain impact on the growth and development of the fetus. For some people, the amniotic fluid becomes less and less. If this continues for a long time, it is very likely to endanger the living space of the fetus, so people need to pay special attention to it. So let me explain why the amniotic fluid is decreasing.

1. Rupture of the amniotic membrane leads to low amniotic fluid

Even a small tear in the amniotic membrane will allow some amniotic fluid to leak out. This can happen at any stage of your pregnancy. However, it is more common near birth. You may discover leakage yourself if you notice your underwear is wet, or your doctor may discover it during an examination.

Rupture of membranes increases the risk of infection for you and your baby because it provides a pathway for bacteria to enter the amniotic cavity. Sometimes, a small tear will heal on its own, and the fluid will stop leaking and return to normal levels. This usually happens if the leak was caused by amniocentesis.

2. Placental problems lead to low amniotic fluid

If there is a problem with the placenta, such as partial abruption, the placenta cannot supply enough blood and nutrients to the baby, resulting in the interruption of amniotic fluid circulation in the fetus.

3. Certain diseases lead to low amniotic fluid

Certain diseases can also cause low amniotic fluid, such as chronic high blood pressure, preeclampsia, diabetes, and lupus.

4. Twins or multiple births cause oligohydramnios

If you are pregnant with twins or more, you may also have oligohydramnios. Oligohydramnios may also occur in cases of twin-twin transfusion syndrome, where one baby has too little amniotic fluid and the other has too much.

5. Fetal malformation leads to oligohydramnios

If you are diagnosed with oligohydramnios in early or mid-pregnancy, it may mean that your baby will have birth defects. If your baby has no kidneys, has abnormal kidney development (called Potter syndrome), or has a blocked urethra, he or she may not produce enough urine to maintain the amount of amniotic fluid. Congenital heart defects can also cause this problem.

The amount of amniotic fluid reflects the development of the fetus to a certain extent. Low amniotic fluid will lead to less space for the fetus to move around, which will cause restricted fetal growth and intrauterine distress. In severe cases, it will cause fetal malformations. If there is too little amniotic fluid, the pregnant mother must pay enough attention to it and consult a professional doctor to take appropriate treatment measures.
