Why do people with advanced kidney disease commonly become anemic?
For three reasons: (1 ) Damaged kidneys produce less erythropoietin and so there is less stimulation of the marrow to produce RBCs. (2 ) Erythropoietin is more easily lost into the urine by leaky kidneys. (3 ) Finally, during dialysis treatment, the patient's erythropoietin is washed away. Treatment for kidney patients today includes injections of synthetic erythropoietin.
