Swelling

Definition:

Swelling is the enlargement of organs, skin, or other body parts. It is caused by build up of fluid in the tissues. The extra fluid can lead to a rapid increase in weight over a short period of time (days to weeks).

Swelling can occur throughout the body (generalized) or only in a specific part of the body (localized).

Alternative Names:

Edema; Anasarca

Considerations:

Slight swelling (edema) of the lower legs commonly occurs in warm summer months, especially if a person has been standing or walking a lot.

Generalized swelling, or massive edema (also called anasarca), is a common sign in severely ill people. Although slight edema may be difficult to detect, especially in an overweight person, massive edema is very obvious.

Edema is described as pitting or non-pitting.
