What can cause edema in the body?

Edema refers to the swelling caused by excess fluid trapped in the body's tissues. This condition can arise from various factors, but one of the primary contributors is excess fluid retention. This can occur for several reasons, such as heart failure, kidney dysfunction, or high salt intake, all leading to the body holding onto more fluid than it should, resulting in swelling in areas like the legs, ankles, and abdomen.

The mechanisms of fluid retention can involve hormonal changes or issues with blood circulation, making it a key factor in the development of edema. Understanding this allows nurses and caregivers to recognize, monitor, and manage patients who are experiencing edema effectively, ensuring they can provide appropriate care and interventions.
