What is kidney failure?
Kidney failure refers to partial or complete loss of renal function.As kidneys perform an important function in body,reduced renal function can result in a host of health problems and symptoms like Anemia, fatigue, headache etc.
Types of kidney failure
Kidney failure can be divided into two types including acute and chronic kidney failure.
Acute kidney failure occurs when your kidneys suddenly become unable to filter wast products from your blood. It develops rapidly over a few hours or a few days.
Chronic kidney failure is a progressive loss in renal function over a period of months or years.It is measured in five stages,which calculated using a patient's glomerular filtration rate (GFR). In different stages of chronic kidney failure, the diet and treatment is also various.
Causes of Kidney Failure
Chronic kidney failure usually occurs as a result of disease or condition which can impair kidney function. It can cause kidney damage to worsen over several months and even years. The following is a list of common causes of chronic kidney failure.
*Diabetes,leading cause of chronic kidney failure
*High blood pressure, the second most common cause
*Glomerulonephritis, a condition in which the filtering units of the kidneys are inflamed
*Genetic kidney disease like polycystic kidney disease (PKD), Alport Syndrome
* Pyelonephritis, recurrent kidney infection
*Prolonged urinary tract obstruction due to enlarged prostate, kidney stones and some cancers
*Vesicoureteral reflux, a condition which can cause urine to back up into kidneys
Acute kidney failure can occur when:
* You have a condition that slows blood flow to your kidneys
