Peripheral Edema: Definition, Uses, and Clinical Overview
Peripheral Edema means visible swelling in the body’s outer tissues, most often in the feet, ankles, and lower legs. It happens when fluid collects in the space between cells (the “interstitial” space). It is a common clinical finding in cardiovascular, kidney, liver, vein, and lymphatic conditions. Clinicians use it as a sign to help guide evaluation, testing, and follow-up.
