Edema definition and facts. 1  Edema is a swelling, usually of the legs, feet, and/or hands due to the accumulation of excessive fluid in the tissues.  The edema that occurs in diseases of the heart, liver, and kidneys is mainly caused by salt retention, which holds the excess fluid in the body.
Not to be confused with volume overload. Hypervolemia, or fluid overload, is the medical condition where there is too much fluid in the blood. The opposite condition is hypovolemia, which is too little fluid volume in the blood. Fluid volume excess in the intravascular compartment occurs due to an increase in total body sodium content and a consequent increase in extracellular body water.
