Introduction
Polyhydramnios refers to an excessive amount of amniotic fluid. Clinically, amniotic fluid volume exceeding 2000 ml is defined as polyhydramnios. In most cases, when there is too much amniotic fluid, the fetus has increased room to move within the uterine cavity, which may lead to abnormal fetal position, premature rupture of membranes, or fetal malformations. Pregnant women should seek medical attention early, identify the underlying cause of polyhydramnios, and communicate promptly with their doctors to receive targeted treatment, so as to avoid delaying the condition.
Excess amniotic fluid refers to polyhydramnios, which in clinical terms is defined as an amniotic fluid volume exceeding 2000 ml. In general, this condition may lead to abnormal fetal position, premature rupture of membranes, fetal malformations, and other complications. The details are as follows:
1. Abnormal Fetal Position
When there is excessive amniotic fluid, the fetus has increased room to move within the uterine cavity, often resulting in malpresentation and increasing the risk of complications such as abnormal fetal position. For cases of polyhydramnios, the underlying cause should be investigated and appropriately managed. The most common cause is elevated maternal blood glucose levels. Pregnant women should reduce intake of sugary foods, avoid drinking cola or fruit juice, and refrain from eating particularly sweet fruits such as watermelon.
2. Premature Rupture of Membranes
Excessive amniotic fluid increases intrauterine pressure, making premature rupture of membranes more likely. Once rupture occurs, a large amount of amniotic fluid can rapidly leak out, creating a connection between the uterine cavity and the vagina. This raises the risk of serious complications such as umbilical cord prolapse, placental abruption, or intrauterine infection, all of which can endanger the fetus's life. In such cases, prompt medical attention and active treatment are recommended. Surgical intervention may be necessary under medical guidance.
3. Fetal Malformations
Moreover, polyhydramnios is frequently associated with fetal malformations, significantly increasing the fetal mortality rate. Generally, the more severe the excess in amniotic fluid, the higher the risk of fetal death. Pregnant women are advised to attend regular prenatal checkups and follow their doctor’s recommendations for a low-salt diet to help control amniotic fluid levels.
In addition to the three main complications above, polyhydramnios may also lead to rapid outflow of amniotic fluid during membrane rupture, umbilical cord prolapse, and increased risk of preterm birth. Pregnant women should seek medical care early to identify the cause of excess amniotic fluid and receive timely treatment to prevent disease progression.
