Dialysis is a type of treatment that repeats many of the functions of the kidneys. It is often used to treat cases of kidney failure, which is also known as end-stage renal disease. This is where the kidneys have been severely damaged and lost almost all of their ability to function. Healthy kidneys clean the blood by removing excess fluid, salt and wastes. When they fail, harmful wastes build up, blood pressure may rise, and the body may retain excess fluid. When this happens, treatment – dialysis or a kidney transplant - is needed to replace the work of the failed kidneys, which is known as end-stage renal failure.
There are two main types of dialyse haemodialysis and peritoneal dialysis. Haemodialysis is the most common method that most people are aware of. It involves inserting a needle, which is attached by a tube to a dialysis machine, into a blood vessel. Blood is transferred from your body and into the machine, which filters out waste products and excess fluids. The clean blood is then transferred back into your body.
Peritoneal Dialysis is a form of renal replacement therapy. It involves instilling dialysis fluid into the peritoneal cavity via a dialysis catheter. Dialysis takes place by diffusion of uremic toxins through the patient's peritoneal capillaries, down a concentration gradient into the dialysis fluid. Water is removed from the circulation by varying the concentration of osmotic agents (normally glucose) in the dialysis fluid to draw water through the capillary membranes. The fluid is repeatedly removed and replaced with fresh solution. Dialysis is an artificial way of doing the work of the kidneys, but it cannot replace the natural efficiency of the kidneys.
If you are on dialysis you need to carefully regulate your diet. Weight loss is a problem that causes particular concern in kidney failure. This is usually because patients are not eating enough protein and energy-providing food. Malnourished people lose weight and muscle mass....
