A condition of having too much amniotic fluid during a pregnancy.
In pregnancy, an excess amount of amniotic fluid, which can increase either gradually or suddenly. Maternal symptoms of polyhydramnios include a larger than expected abdominal size, abdominal discomfort, breathlessness, nausea, or swelling of the legs. It is diagnosed by physical examination and ultrasound. Tests may be done to check for fetal abnormalities. In most cases, the fetus is normal and no treatment is required. Sometimes, excess fluid is removed to relieve symptoms, using a procedure similar to amniocentesis.
A condition in which the volume of amniotic fluid exceeds 2000 ml during the last half of pregnancy. Acute polyhydramnios occurs suddenly between 20 and 24 weeks’ gestation and is marked by a rapid (within a few days) increase in volume. Chronic polyhydramnios, a continuous, gradual increase in volume throughout the last trimester, is more common. Uterine overdistention may result in preterm labor.
Increased amniotic fluid around the fetus during pregnancy.
The condition frequently has an unidentified cause. It can sometimes arise if the fetus has a deformity that prevents normal swallowing, or if the expecting mother has diabetes mellitus.
The buildup of extra amniotic fluid typically occurs during the latter part of pregnancy, manifesting symptoms around the 32nd week. The primary symptom is discomfort in the abdomen. Other potential symptoms include shortness of breath and leg swelling. The size of the uterus is larger than anticipated.
Sometimes, acute polyhydramnios develops. This leads to a swift accumulation of fluid, resulting in abdominal discomfort, shortness of breath, nausea, vomiting, and swollen legs. The abdomen feels tight, and its skin appears glossy. This condition might lead to preterm labor.
The condition can typically be identified through a physical examination, though an ultrasound might be necessary. For milder cases, rest might suffice. In more extreme cases, removal of some amniotic fluid through a needle may be required. If it’s late in the pregnancy, inducing labor might be considered.
