Kidney Failure means kidney loses its abilities due to some reasons. Normally, the healthy kidneys are responsible to responsible for discharging extra wastes and toxins from the blood, discharge extra fluid from the body, and keeping electrolyte and acid-base balance. Kidney disease can also cause legs and ankle swelling. When kidneys are not functioning properly, fluid can build up in the body. Due to gravity, it often occur in patients’ legs, ankles and feet. In addition, when filtering units called glomerulus are damaged, useful substance will leak into urine through the hole of glomerulus.
