Polyhydramnios

Polyhydramnios is when you have too much amniotic fluid during pregnancy. Amniotic fluid is the liquid that surrounds the fetus in your uterus. Amniotic fluid plays a significant role in the fetus’s growth and development.

This condition usually happens in the second half of pregnancy, but it may occur as early as 16 weeks into pregnancy. Mild polyhydramnios doesn’t usually cause complications. Your pregnancy care provider will monitor you closely in case your condition worsens and treatment is necessary.
