Edema is caused by extra fluid trapped within the body’s tissues, leading to swelling.
When there is excess fluid trapped within tissues of the body, edema – or swelling – can result. This condition can affect any part of a child’s body, but it most commonly occurs in the hands, arms, feet, ankles and legs.
The causes of edema are varied, and can include:
Eating too much salt or salty foods
Staying in the same position for an extended period of time
