Polyhydramnios is a medical condition characterized by an excess of amniotic fluid surrounding a developing fetus during pregnancy. Amniotic fluid plays a crucial role in protecting the fetus and allowing for movement, but too much fluid can lead to complications. It is typically diagnosed through ultrasound examinations. The causes of polyhydramnios can vary and may include multiple pregnancies, certain maternal health conditions, or fetal abnormalities. Symptoms may include rapid growth of the abdomen and discomfort. Management often involves monitoring the pregnancy closely and addressing any underlying issues to ensure the health of both the mother and the baby.
