Definition: Edema is the swelling that can occur when watery fluid collects in the spaces between the cells of the body. The condition usually affects the legs, ankles and feet. However, edema can also occur in other parts of the body. For example, macular edema occurs around the eyes, and abdominal edema can sometimes accompany disease such as liver failure.
Edema can be a symptom of a variety of medical conditions, such as heart, kidney or liver failure.
Sometimes, though, edema is not associated with a disease, and can occur as a result of prolonged standing or sitting. This is more common in pregnant women and older adults.
