what causes swelling in lower legs
Slight swelling (edema) of the lower legs is common in warm summer months, especially if a person has been standing or walking a lot. General swelling, or massive edema (also called anasarca), is a common sign in people who are very sick.
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). Swelling can occur all over the body (generalized) or only in one part of the body (localized).
