You did not say how long you have had kidney disease or what stage. Have you seen a nephrologist? Does he/she agree with your assessment? Kidney damage can "sometimes" be reversed, chronic cannot. From the beginning of this year, I have worked with an acupuncturist weekly who brought me from Stage 4 to Stage 3A, but she also has a PhD in Immunology. The point being, it may take some help to stay fit.
