Chronic kidney disease
Chronic kidney disease means your kidneys have been working below normal for three months or more. It is common, it is often silent, and in most people it can be slowed.
The basics
What the stages mean
Doctors describe kidney function in five stages, based on how well your kidneys filter. The stage is not a countdown. Many people stay at the same stage for years.
Stage 1
Normal filtering, but signs of kidney damage
Stage 2
Mildly reduced filtering, with signs of damage
Stage 3a
Mild to moderate reduction in filtering
Stage 3b
Moderate to severe reduction in filtering
Stage 4
Severely reduced filtering
Stage 5
Kidney failure. Dialysis or transplant is considered
