What's caused by damaged capillaries in the kidneys so the nephrons can no longer filter blood?
colon failure
bacteria failure
sponge failure
kidney failure
Untreated diabetes may damage capillaries in the kidneys so the nephrons can no longer filter blood. This is called kidney failure. The only cure for kidney failure is to receive a healthy transplanted kidney from a donor. Until that happens, a patient with kidney failure can be kept alive by artificially filtering the blood through a machine. This is called hemodialysis. You can see how it works in Figure below .
