In some cases, the cause of hydrops fetalis isn’t known. Immune hydrops fetalis usually occurs when the blood types of the mother and the fetus aren’t compatible with each other. This is known as Rh incompatibility. The mother’s immune system may then attack and destroy the baby’s red blood cells.
What you should know about hydrops fetalis?

- Hydrops fetalis is severe swelling (edema) in an unborn baby or a newborn baby. ...
- Hydrops develops when too much fluid leaves the baby's blood and goes into the tissues.
- It is almost always diagnosed during pregnancy or right at birth.
