Renal dialysis diet is recommended to patients who are undergoing dialysis. The purpose of this diet is to maintain a balance of electrolytes, minerals, and fluid in patients who are on dialysis. The special diet is important because dialysis alone does not effectively remove ALL waste products. These waste products can also build up between dialysis treatments.
On the other side of the coin, renal dialysis is an artificial process by which waste products and excess fluid are removed from the body by diffusion from one fluid compartment to another across a semipermeable membrane.
MEMBRANE
Active or mechanical dialysis cycles blood through a machine (dialyzer) or cycles dialyzing fluid into and out of the clients abdominal cavity (peritoneum) through a semipermeable membrane to remove impurities and toxins and to maintain fluid, electrolyte and an acid-base balance. Passive dialysis uses the client's peritoneal membrane as the filter.
Acute renal failure may require dialysis until the client's kidney function improves and starts filtering the client's blood independently. ESRD is defined as irreversible, chronic renal failure requiring regular dialysis or a kidney transplant to sustain life.
There are two types of dialysis procedures in common clinical usage: hemodialysis and peritoneal dialysis. Both of them requires renal dialysis diet as a supplementary course of action.
During the hemodialysis process, blood passes through an artificial kidney machine and the waste products diffuse across a synthetic membrane into a bath solution known as dialysate after which the cleansed blood is returned to the client's body. Hemodialysis is accomplished usually in three- to four-hour sessions, three times a week.
Occasionally, medical complications occur where a client retains more fluid than is healthy following a regular dialysis treatment. Ultrafiltration is a process of removing excess fluid from the blood through a dialysis membrane by exerting pressure. This procedure is part of a hemodialysis treatment and is included in the composite rate for the hemodialysis treatment. Ultrafiltration is not a substitute for dialysis.
During the peritoneal dialysis process, waste products pass from the client's body through the peritoneal membrane into the peritoneal (abdominal) cavity where the dialysate is introduced and removed periodically.
Renal dialysis diet is used as an adjunct to patients undergoing dialysis. This special diet will also help you maintain proper fluid and electrolyte levels in between dialysis treatments. Coupled with dialysis, it will effectively help you feel as good as possible and lessen complications from the build up of toxins from having renal disease.
