The Truth About Dialysis
(From Wikipedia, the free encyclopedia)
In medicine, dialysis (from Greek dialysis,“διάλυσις”, meaning dissolution, dia, meaning through, and lysis, (meaning loosening or splitting) is a process for removing waste and excess water from the blood, and is used primarily as an artificial replacementfor lost kidney functionin people with renal failure.Dialysis may be used for those with an acute disturbance in kidney function (acute kidney injury, previously acute renal failure), or progressive but chronically worsening kidney function–a state known as chronic kidney diseasestage 5 (previously chronic renal failure or end-stage renal disease). The latter form may develop over months or years, but in contrast to acute kidney injury is not usually reversible, and dialysis is regarded as a “holding measure” until a renal transplantcan be performed, or sometimes as the only supportive measure in those for whom a transplant would be inappropriate.
The kidneyshave important roles in maintaining health. When healthy, the kidneys maintain the body’s internal equilibrium of water and minerals (sodium, potassium, chloride, calcium, phosphorus, magnesium, sulfate). The acidic metabolismend-products that the body cannot get rid of via respiration are also excreted through the kidneys. The kidneys also function as a part of the endocrine system, producing erythropoietinand calcitriol. Erythropoietin is involved in the production of red blood cells, and calcitriol plays a role in bone formation.Dialysis is an imperfect treatment to replace kidney function because it does not correct the compromised endocrine functions of the kidney. Dialysis treatments replace some of these functions through diffusion(waste removal) and ultrafiltration(fluid removal). 
When your kidneys are not able to function at more than 10 percent, then you will need dialysis. Dialysis is a replacement for the non-working kidneys. Since your kidneys are no longer able to remove the toxins and waste materials from your blood, regular dialysis treatments become necessary.
Without the dialysis procedure your body would become overloaded with a build-up of salts and a rise in your blood pressure. Your body would become toxic from the waste materials, leading to others problems such as diabetes, heart failure, and possibily cancer.
If you have acute kidney failure, then you may be able to get by with a few dialysis treatments. If you have chronic kidney failure, dialysis will be required on a regular basis of 2 to 3 times a week until you can get a kidney transplant.
The Truth about Dialysis – Different Methods
Hemodialysis and peritoneal dialysis, the two main types of dialysis, use the same principles, but, use a different procedure.
In hemodalysis, an artificial kidney called a hemodialyzer is used. The surgeon will perform a minor procedure to create a permanent port, in your arm or leg to attach the hemodialyzer. The artificial kidney will be attached to allow the blood to flow through it, removing the toxins, then back into your body.
This is usually done about 3 times a week, taking about 4 hours for each session, depending on your condition.
In the procedure called peritoneal dialysis, a port is placed in your abdoen, and a catheter is incerted. The abdomen is filled with a solution of dialysate that filters the waste materials from your blood as it circulates through your veins and arteries through osmosis. I’m sure you studied that in high school.
Dialysis is not a cure, but, just a treatment to manage your now deteriorating kidneys. The procedure is time consuming and you often will have to continue the process for the rest of your life, or get a transplant. You can live a fairly normal life.
Hemofiltration is similar to hemodialysis. A pressure gradient is used and water is moved rapidly across a permeable membrane, pulling the dissolved waste materials with it. No dialysate is used in this procedure. The waste material is replaced with a fluid that acts as a substitute fluid that is mixed into the external corporeal circuit. This procedure uses methods from hemodialysis and hemofiltration.
There is one more procedure call intestinal dialysis. A lot of soluble fibers such as acacia fiber, is digested into the colon. This cause a rapid growth of bacteria in the colon producing nitrogen which is eliminated in your bowel movements.
Another method that you may have to use is to add 1 to 1.5 liters of polyetheylene glycol or manritol 3 times a day. These solutions are not absorbed into your body, but eliminated through your bowels.
The Truth about Dialysis – Doesn’t Sound Like Fun
None of these procedures are a pleasant experience. We should do our best to try avoid them by guarding our health very carefully. Pay close attention to your diet. Get plenty of fresh air, exercise, and pure water.
If you are willing to make the necessary changes in your lifestyle, you can often prevent kidney damage or, if you are already suffering from kidney disease, there is a good possibility that you can stop, or even reverse kidney disease using natural methods.
