Kidney may be small in size but they perform major function in human and animal. Kidneys maintain our overall health, including filtering waste product and unnecessary fluid from blood. Serious kidney failure is life threading and patient can not without kidney transplant. Sometime the patient need to dialysis for stay alive. While effective treatments are available for many kidney diseases, people are sometimes unaware that kidney disease can often be prevented.

What causes kidney failure?

There are a lot of known causes of kidney failure. But huge number of people the causes is never found. The most common causes of kidney failure are high blood pressure, diabetes, certain toxin, injury, painless inflammation of the kidney which called glomerunephritis.

Cyst in the kidney is another major cause of kidney failure. Repeated kidney infections or kidney infections (pyelonephritis) in childhood; and obstruction to the urine flow.

What can causes chronic kidney failure?

The main function of kidney is filtration excess waste product and excreted from body. Excess fluid material are removed from blood is also one of the major function of kidney. From renal arteries kidneys get their oxygen and blood supply, which are branches of the abdominal aorta (another artery). When it enters the kidneys, blood goes through smaller and smaller blood vessels – the smallest ones being the glomeruli (tiny capillary blood vessels which are arranged in tufts).

In glomeruli the blood become filtrate and waste product, fluid and other excess substance are excreted and pass through miniscule tubules, from which the bloodstream reabsorbs what the body is able to reuse. What the body cannot reuse – waste – is excreted in our urine.

Kidneys are able to excrete all waste products and excess material most cases. But sometime kidneys cannot able to do it properly due to blood flow on kidney is affected of the tubules or glomeruli are not working properly because of damage or disease, or if urine outflow is obstructed, problems can occur.

What can cause kidney failure usually?


Diabetes is one of the major causes of kidney failure. Both types I and II diabetes are responsible for chronic kidney failure. If diabetic patient not control his diabetes, excess blood sugar is accumulate into blood and it can damage glomeruli.

Type I diabetes are more responsible for chronic kidney failure. Approximately 20% to 40% of patients with Diabetes Type I develop kidney disease by the time they are 50 years of age.

Kidney disease is not common during the first ten years of diabetes; it more commonly occurs between years 15 to 25 after diagnosis (of diabetes). However, as treatment methods improve, experts say that the number of diabetes patients developing kidney disease is falling.

High blood pressure

It is one of the major causes of chronic kidney damage. Higher blood pressure can damage glomeruli, for this reason kidney cannot do it work properly.

Known risk factors for high blood pressure include:

  1. Age (the risk of developing high blood pressure increases as you get older).
  2. Family history of high blood pressure (the condition seems to run in families).
  3. Being of African-Caribbean or south Asian origin.
  4. Obesity.
  5. Lack of exercise.
  6. Smoking.
  7. Excessive alcohol consumption.
  8. High amount of salt in your diet.
  9. High-fat diet.
  10. Stress.

Certain toxin

Certain toxic agent can damage kidney Such as carbon tetra chloride and lead very much dangerous for kidney.

Illegal drug abuse

Some illegal drug like heroin, cocaine is effect kidney badly.


Inflammation in the tiny filters (glomeruli) within the kidneys; this can happen after strep infection and other conditions of unknown cause.

Kidney failure symptoms

Kidney failure symptoms are observed when it unable to done its regular function. Major kidney failure symptoms are:

  1. Fluid retention. As a result causing swelling in feet, legs and ankles. It is one of the major kidney failure symptoms.
  2. Decreased urine output.
  3. It is another major kidney failure symptom.
  4. Fatigue.
  5. Nausea.
  6. Coma in severe cases.
