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.
