The kidneys are sophisticated units that process blood to filter out waste products and extra water. The waste and extra water becomes urine, which flows to the bladder through tubes called ureters. It is stored in the bladder until urination occurs. The wastes in the blood come from the normal breakdown of active tissues and from the food you eat.

Kidney Failure

After the body has taken what it needs from the food, waste is sent to the blood. If kidneys do not remove the wastes, they build up in the body.

The actual filtering occurs in tiny units inside the kidneys called tubules. In the nephron, a glomerulus- which is a tiny blood vessel, or capillary- interwines with tiny urine- collecting tube called a tubule. A complicated chemical exchange takes place, as the waste materials and water leave the blood and enter the urinary system. The kidneys regulate the body’s level of substances like sodium, phosphorus and potassium whose right balance is necessary for life but excess levels can be harmful.

In addition, kidneys release three important hormones:
Erythropoietin- which stimulate bone marrow to make red blood cells.
Renin- which regulates blood pressure.
The active form of vitamin D, which helps maintain calcium for bones and for normal chemical balance in the body.

Kidney diseases attack the nephrons, causing them to lose their filtering capacity. Most kidney diseases destroy the nephrons slowly and silently and may take years for the damage to become apparent. The two most common causes of kidney disease are hypertension and diabetes.


This makes the heart to work harder and over time can damage the blood vessels throughout the body. If the blood vessels in the kidneys are damaged, they cannot filter wastes and extra fluid from the blood as they are supposed to. The extra fluid in the blood vessels may then raise blood pressure even more. It is a dangerous cycle.

Diabetic Nephropathy

Diabetes is a disease that keeps the body from using glucose (sugar) as it should. If glucose stays in the blood instead of breaking down, it acts like a poison. Damage to the nephrons from glucose is called diabetic nephropathy. This can be prevented or delayed by keeping the blood glucose down.

Types Of Renal Failure

Acute renal failure (ARF): This is a sudden drop in Kidney function. It can be caused by direct injuries to the kidneys, acute blood loss or taking harmful substances. ARF may be reversed or could lead to permanent loss of kidney.

Chronic renal failure (CRF): This results from gradual loss of kidney functions. You may have “silent” Kidney disease for years.

End Stage Renal Disease (ESRD): This is a condition of total or near total and permanent Kidney failure. People with ESRD must undergo dialysis or kidney transplantation to stay alive.

CRF is makes life hell, and dialysis is so expensive.

Thanks you friends for your contributions.. @ Wonder, I have been with a lot of Kidney failure patients and it is exactly as you have said, it isn't a good experience for them at all...
