A condition called polyhydramnios occurs when there is an abnormally high amount of amniotic fluid in the amniotic sac surrounding the fetus during pregnancy, which may indicate an underlying medical problem.
There are several factors that can cause polyhydramnios, including:
Factors related to the fetus: Conditions such as gastrointestinal or neurological abnormalities can impair the fetus's ability to swallow and absorb amniotic fluid, leading to an accumulation of fluid in the amniotic sac.
Amniotic fluid production can be increased by maternal conditions like gestational diabetes, preeclampsia, or certain infections.
In cases of multiple gestations, abnormalities of the placenta, such as placental chorioangiomas, can also contribute to polyhydramnios.
In some cases of polyhydramnios, pregnant women may experience the following symptoms:
Swelling or discomfort in the abdomen caused by an enlarged uterus.
Diaphragmatic pressure caused by the enlarged uterus makes breathing difficult, especially while lying down.
In pregnancy, rapid weight gain is often caused by fluid retention.
Polyhydramnios is typically diagnosed through a combination of prenatal screening tests, ultrasound imaging, and clinical evaluation. Common diagnostic tests include:
To assess the volume of amniotic fluid and confirm polyhydramnios, ultrasound scans can measure the amniotic fluid index (AFI) or deepest vertical pocket (DVP).
Monitoring of the fetus: Fetal ultrasound can be used to check for structural abnormalities or signs of distress in the fetus.
A woman with polyhydramnios may undergo additional tests to assess for underlying maternal conditions that may contribute to the excess fluid in the womb.
A variety of treatment options are available for polyhydramnios, depending on the severity of the condition and the presence of any underlying factors contributing to the excess amniotic fluid.
In amnioreduction, excess amniotic fluid is removed through a procedure called amniocentesis, which can alleviate symptoms and reduce the risk of complications like preterm labor.
To detect complications and manage them promptly, close monitoring of both mother and fetus is essential. This may include prenatal check-ups, fetal monitoring, and ultrasound scans.
If polyhydramnios is caused by an underlying fetal or maternal condition, treatment may focus on treating or managing the condition to reduce fluid accumulation.
It is difficult to prevent polyhydramnios because it is often caused by underlying medical conditions. It is important to maintain a healthy lifestyle during pregnancy, attend regular prenatal checks, and follow medical advice in order to reduce complications and improve outcomes.
