Renal kidney failure is also known as end-stage renal disease (ESRD), and over 660,000 Americans are living with the disease. Kidneys perform critical functions in the body. They work to remove waste and excess water from the body. They filter about a half of cup of blood every minute to remove such waste and fluids.
There are five stages of kidney disease, and Stage 5 is kidney failure. Kidney failure occurs when the kidneys are no longer able to filter the waste and excess fluids from the blood. As a result, waste and fluids can buildup in the body.
ESRD should not be confused with acute kidney failure. Acute kidney failure occurs when the kidneys suddenly stop working within a few days, but it is possible it can be reversed. There is no cure for ESRD, and patients only have a few treatment options noted later in this article.
