What are some common causes of impaired renal function?
Acute kidney failure can be reversible, according to Mayo Clinic. First, the cause of the kidney failure, such as infection, obstruction or dehydration, must be treated. Fluids, medications and electrolytes may be given intravenously to help the body keep chemicals and electrolytes balanced while the kidneys heal. In some cases, temporary dialysis is needed. During dialysis, a machine filters toxins and waste from the blood, a job normally done by the kidneys. If the kidney damage is reversible, dialysis can be discontinued after the injury to the kidneys heals.
