Introduction
Whether excess amniotic fluid in pregnant women has an impact depends on the degree of the increase. Slight excess of amniotic fluid typically does not affect the mother or fetus. However, significantly higher-than-normal amniotic fluid levels may lead to abnormal fetal positions such as breech or transverse presentation, thereby complicating delivery. Excess amniotic fluid increases uterine tension, which may cause maternal hypoxia, resulting in fetal distress in utero, premature rupture of membranes, placental abruption, and in severe cases, fetal death.

Whether excessive amniotic fluid in pregnant women has an impact depends on the degree of excess. The specific analysis is as follows:

1. No impact

During pregnancy, the normal range for amniotic fluid is 3–8 cm. If the increase in amniotic fluid is mild, it usually does not affect the mother or fetus. It is recommended to eat diuretic foods, maintain a light diet, and reduce intake of high-sugar, high-salt, and high-fluid foods.

2. With impact

If the amount of amniotic fluid significantly exceeds the normal range, it may cause fetal malposition such as transverse or breech presentation, affecting normal delivery. Excessive amniotic fluid can also increase uterine tension, potentially leading to maternal hypoxia and breathing difficulties. It may impair blood circulation in the uterus and placenta, resulting in fetal distress in utero, premature rupture of membranes, placental abruption, or other complications. In severe cases, it could lead to fetal death.

Timely medical attention is necessary when excessive amniotic fluid occurs. Active treatment under a doctor's guidance is essential to prevent worsening symptoms.
