Having kidney failure means that most (85–90 %) of your kidney function is gone. Your kidneys don't work well enough to carry out all their functions. Kidney failure can be sudden or gradual.
- Acute kidney failure is often short-lived, but you need treatment until your kidney function returns.
- Chronic kidney disease develops over time and is related to a number of risk factors, including diabetes and high blood pressure.
There is no cure for kidney failure, but with treatment you can live a long, active life and continue to do the things you enjoy.
