Edema: Fluid Accumulation in Legs and Ankles Explained

Edema is the medical term for abnormal fluid accumulation in the interstitial spaces, commonly seen in the legs and ankles. It occurs when venous return or lymphatic drainage is impaired, causing fluid to leak from capillaries into surrounding tissues.

Common causes include heart failure, venous insufficiency, kidney disease, liver cirrhosis, medications, and prolonged sitting/standing. Treatment targets the underlying condition and may involve compression, elevation, diuretics, and lifestyle changes.
