What is Kidney Failure?

When you have kidney failure, one or both kidneys aren't able to work normally. The kidneys remove waste (in the form of urine) from the body. They also balance the water and electrolyte content in the blood by filtering salt and water.

Kidney failure is divided into two categories:

• Acute kidney failure -sudden loss of kidney function
• Chronic kidney failure -slow, gradual loss of kidney function
