Acute Renal Failure

When ARF occurs, waste products, such as nitrogen or salt, and excess fluids are not removed by the kidneys and builds up in the body, upsetting the body's normal chemical balance. Chemicals and electrolytes, such as sodium, potassium, and calcium,

which are needed for normal body functioning, become harmful or sometimes poisonous (toxic) to the body when they reach abnormally high or low levels.
