How is it treated?

The treatment of acute kidney failure depends on the cause of renal failure. The specialist identifies the origin and proceeds with the treatment accordingly.


  • Medications

    • To control blood potassium: The specialist may prescribe calcium, sodium polystyrene sulfonate and glucose to prevent the build-up of potassium in the patient blood. High level of potassium in the blood can cause muscle weakness and arrhythmias.
    • To Restore Blood Calcium: The specialist may prescribe calcium medication to increase the calcium level in the patient's blood.

  • Dialysis

    The specialist removes the excess fluids and toxins from the patient's body which helps to balance the amount of fluids in the blood. An artificial kidney is used to pump out blood from the body and filter out waste from the blood and pump it back to the patient's body.
