What is Renal Failure or Kidney Failure?

Renal Failure is a pathologic state the part or complete loss of renal function, which is caused when various chronic kidney diseases develop into end stage. The word renal refers to kidneys, so you may see both of these words used. Therefore, Renal Failure and Kidney Failure mean the same thing—the kidneys are not functioning properly or no longer work at all. Renal failure can be a progressive disease or a temporary one depending on the cause and available treatment options.
In renal failure, the kidneys undergo cellular death and are unable to filter wastes, produce urine and maintain fluid balances. This dysfunction causes a build up of toxins in the body which can affect the blood, brain and heart, as well as cause other complications. Renal failure is very serious and even deadly if left untreated.
There are two types of Renal Failure: acute and chronic. Acute Renal Failure occurs suddenly and is usually initiated by underlying causes, for example dehydration, infection, serious injury to the kidney or the long-term use of over the counter pain medications like Tylenol (acetaminophen) or Advil (ibuprofen). Acute Renal Failure is often reversible.

The main reason of Chronic Renal Failure is the long-term renal pathological changes. As time goes by and disease progresses, the renal function gradually reduce, which finally leads to Renal Failure. Chronic Renal Failure is more serious than Acute Renal Failure, because symptoms may not appear until the kidneys are extremely damaged. Chronic Renal Failure can be caused by other long term diseases, such as diabetes and high blood pressure.
