What is the reason for the decrease of amniotic fluid in late pregnancy

If there is a decrease in amniotic fluid in the late pregnancy, it can often lead to respiratory distress in the fetus, which is quite harmful to the health of the fetus. There are many reasons for the decrease in amniotic fluid in the late pregnancy. For example, if there is an abnormality in the placenta, there will often be an unbalanced intake of nutrients, which may lead to a decrease in amniotic fluid. In addition, some diseases of the pregnant woman herself may also lead to a decrease in amniotic fluid. Let's take a look at this aspect.

What is the reason for the decrease of amniotic fluid in late pregnancy

1. Rupture of the amniotic membrane leads to low amniotic fluid. The rupture of the amniotic membrane in the late pregnancy will cause the amniotic fluid to flow out, resulting in a decrease in the amount of amniotic fluid, which is more common when the pregnant woman is close to giving birth.

2. Placental problems lead to low amniotic fluid. Placental abnormalities result in the inability to provide adequate nutrition to the fetus, leading to interruption of amniotic fluid circulation. Interruption of amniotic fluid circulation will reduce amniotic fluid, which is not conducive to the development of the fetus.

3. Physical illness of pregnant women leads to low amniotic fluid. If a pregnant woman suffers from diseases such as diabetes, chronic hypertension, preeclampsia, etc., it may also lead to low amniotic fluid.

4. Fetal malformation leads to low amniotic fluid. Part of the amniotic fluid in the pregnant woman's uterus in the late pregnancy is also composed of the fetus's urine. If the fetus is underdeveloped or suffers from congenital urinary system diseases, which causes the fetus to have oliguria or anuria, it will also lead to less amniotic fluid in the late pregnancy.

5. The fetus develops slowly. Malnutrition of the pregnant woman or insufficient nutritional supplements can lead to slow fetal development and reduce amniotic fluid in the late pregnancy.

What to do if the amniotic fluid decreases in late pregnancy

For those who have reached full-term pregnancy and whose fetus can survive outside the uterus, the pregnancy should be terminated promptly. If there is combined placental dysfunction, fetal distress, or little amniotic fluid and severe meconium contamination at rupture of membranes, and smooth delivery is impossible, cesarean section should be performed in time to terminate the pregnancy in order to reduce the fetal mortality rate.

However, if the fetal reserve function is still good, there is no obvious intrauterine hypoxia, and the amniotic fluid is clear after artificial rupture of membranes, vaginal trial delivery can be adopted. If you choose vaginal trial delivery, you need to closely observe the progress of labor and continuously monitor changes in fetal heart rate.

This is all we have to say about the reasons why the amount of amniotic fluid decreases in the late pregnancy. If a pregnant woman experiences a decrease in amniotic fluid, there is no need to worry too much as long as the fetus is in good health and there are no abnormalities. If expectant mothers want to maintain sufficient amniotic fluid, they should drink more water, eat more fresh vegetables and fruits, pay attention to rest, and exercise properly, which can help produce healthy amniotic fluid.
