Diet in Diseases of the Kidneys-
Diet for Dialysis

Wastes in the blood come from food and liquids that are consumed. People on dialysis must adhere to a dialysis diet to cut down on the amount of waste in their blood. Following a diet for dialysis will delay total kidney failure.

What is Dialysis

Dialysis is a procedure that replaces some of the kidneys normal functions. It is performed when a person experiences kidney failure, usually more than 95% of normal kidneys.

There are two basic kinds of Dialysis :

  • Haemodialysis
    In this an artificial kidney, haemodialyser is used to remove the waste products from the blood and restore the bodys chemical balance. Haemodialysis is done approximately 3-4 hours and usually three times a week. Haemodialysis patients are unable to take oral supplements, inter-dialytic parenteral nutrition is a means of providing adrenate calories and proteins.
  • Peritoneal dialysis
    In this type patients blood is cleaned continuously within the body, The blood stays in the blood vessels which line the patients abdominal (peritoneal) space. In peritoneal dialysis clearance of low molecules weight substances are less than for haemodialysis.

Nutritional requirement during various stages of renal failure.
