CNN is reporting Nelson Mandela is on dialysis. http://t.co/HZTIlmGrtO. This means he is suffering from Acute Kidney Injury, the disease I study. Having to have dialysis is very serious. Unfortunately, survival rates are only about 50% by this stage, less in the very elderly. Dialysis is not a treatment, merely a support for the kidney to try and give them time to recover function on their own and a means to remove toxins from the body.
