Definition

By Mayo Clinic staff

Edema is swelling caused by excess fluid trapped in your body's tissues. Although edema can affect any part of your body, it's most commonly noticed in your hands, arms, feet, ankles and legs.

Edema can be the result of underlying medical conditions, certain medications or pregnancy.

Identifying and treating the underlying cause of edema is key to effectively controlling it. Self-care measures coupled with medication that removes excess fluid usually can effectively treat edema.
