👉 Fluid accumulation, or edema, occurs when excess fluid builds up in the body's tissues, often due to a disruption in the balance between fluid intake and output. This imbalance can result from various factors, including inflammation, injury, or increased pressure in blood vessels. When the body's lymphatic system, responsible for draining excess fluid, is overwhelmed or damaged, fluid leaks out of blood vessels into the surrounding tissues, leading to swelling. Conditions such as heart failure, kidney disease, and certain medications can exacerbate this process, causing fluid to accumulate in areas like the legs, ankles, or abdomen.
