My sister thinks that her levels variation is due to the fact that she is old, and sometimes her kidney
works, sometimes her kidney
doesn't work. This would explain Creatinine variations, if she has Chronic Renal Failure because of aging and not because of phosphorus or other disease. My sister doesn't think she is cured, she thinks she is old, and that's what is causing all the health problems. And she says: you cannot cure from aging.
