What is chronic kidney failure?
Chronic kidney failure is the gradual loss of kidney function, according to the Mayo Clinic.
Since your kidneys filter waste and fluids out of your blood, dangerous levels of waste can accumulate in your body during the advanced stages of kidney failure, the Mayo Clinic states.
A person may not show signs of kidney failure until his or her kidney function is reduced.
While doctors can treat the issues that lead to kidney failure, eventually patients may need dialysis or a kidney transplant, the Mayo Clinic states.
