I’m 77. I had CKD and developed cancer in my right kidney. Last year I had radical nephrectomy. Since then I did my research and I found an excellent dietitian online who taught me how to eat a kidney healthy diet. She is a kidney diet specialist. After about 4 months my EGFR went from 40 to 51! It has not been that good in years. Please research kidney friendly diet. If you want I can give you the information for my dietitian. I went through 3 different dietitians before I found one that actually helped.
