Swelling is the enlargement of organs, skin, or other body parts. It is caused by a buildup 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).

Context Explanation

Swelling can occur all over the body (generalized) or only in one part of the body (localized). Swelling (edema) happens when fluid accumulates in the body’s tissues. Being swollen can happen anywhere in the body, but it commonly occurs in the lower legs, abdomen, chest (in or around the lungs), and hands. Edema (American English), also spelled oedema (Commonwealth English), and also known as fluid retention, swelling, dropsy and hydropsy, is the build-up of fluid in the body's tissue.
