The Facts

Chronic renal failure, or chronic kidney disease (CKD), is a slow and progressive decline of kidney function. It's usually a result of a complication from another serious medical condition. Unlike acute renal failure, which happens quickly and suddenly, chronic renal failure happens gradually - over a period of weeks, months, or years - as the kidneys slowly stop working, leading to end-stage renal disease (ESRD).

The progression is so slow that symptoms usually don't appear until major damage is done. In the United States, approximately 1 in 1,000 people are getting treated for ESRD, and more than 19 million adults are living with some type of CKD.

The kidneys play three major roles:

  • removing waste products from the body, keeping toxins from building up in the bloodstream
  • producing hormones that control other body functions, such as regulating blood pressure and producing red blood cells
  • regulating the levels of minerals or electrolytes (e.g., sodium, calcium, and potassium) and fluid in the body

It's entirely possible to live a full, healthy life with only one kidney - one fully functioning kidney can do the work of two - but it's essential to watch for signs of any problems with the remaining kidney.

When kidneys get to the point where they can't function at all, kidney dialysis or a transplant is the only way to remove the body's waste products.
