What is edema?
The definition of edema is observable swelling from fluid accumulation in body tissues. Edema most commonly occurs in the
ankles, legs, and/or hands where it is referred to as peripheral edema. Edema of the
foot is sometimes called pedal edema. The swelling is the result of the accumulation of excess fluid under the skin in the spaces within the tissues.
All tissues of the body are made up of cells, blood vessels, and connective tissues that hold the cells together
called the interstitium. Most of the body's fluids that are found outside of the cells are normally stored in two spaces; the blood vessels (as the "liquid" or serum portion of your blood) and the interstitial spaces (not within the cells). In various diseases, excess fluid can accumulate in either one or both of these compartments.
The body's organs have interstitial spaces where fluid can accumulate, and
there are a number of different types of edema. An accumulation of fluid in the interstitial
tissue around the air spaces (alveoli) in the lungs occurs in a disorder called pulmonary edema. In addition, excess fluid sometimes collects in what is called the third space, which includes cavities in the abdomen (abdominal or peritoneal cavity - called "ascites") or in the chest (lung or pleural cavity - called "pleural effusion").
Anasarca or extreme generalized edema refers to the severe, widespread accumulation of fluid in the all of the tissues and cavities of the body at the same time.
Cerebral edema is an accumulation of excess fluid in the brain.
