The life expectancy with third-stage kidney failure cannot be determined because it is considered the middle stage with a good chance for the patent's condition to improve, according to Kidney Failure Web. There are other determining factors as well, such as age, gender and cause of renal failure.
Most kidney diseases are progressive and chronic and are divided into five stages according to the progression of the illness, the kidney functions and the patent's creatinine level, says Kidney Cares. Stage 3 is when a patient's glomerular filtration rate falls below 60 milliliters per minute but is still higher than 30. This means the kidneys are moderately damaged, but the illness is not severe enough to begin dialysis or discuss kidney transplant.
Stage 3 patients still have a good chance to reverse renal damage and improve their kidney functions, especially in the early stages of stage 3. If further damage is prevented and kidney function improves to higher than 50, the patent's life expectancy improves, advises Kidney Cares. Stage 3 is a crucial stage that can rapidly progress into stage 4 and 5, so early treatment is key in determining the overall life expectancy of someone with stage 3 kidney failure.
