How is edema caused by fluid overload?

Answer 1

Edema is not so much about fluid overload in the body than a specific area getting, or accumulating, more than other areas. The fluid in our bodies is managed by the lymphatic system, and if it is blocked, or perhaps overloaded in a specific part of the body, then edema, or swelling of fluid, develops.

Answer 2

Edema is a type of swelling, where a body holds on to fluid. It may occur because of a medical condition, or from taking certain pills.
