At the beginning of my renal journey I was also told by PCP AND neurologist that I was getting old, deal with it and diet changes would not help! My GFR was 29 due to changes in co-morbidities. I was already on Connect for other issues so I did my extra reading and read the suggestions here. I majorly focus on Mentors’ suggestions, which was ‘’go with diet changes’’! Diet plays a very important role in most medical issues so I put myself on renal diet ‘’cold turkey’’ …had already stopped salt 55 years ago. My GFR improved on first subsequent lab and is now ‘’normal’’ again. I do ‘’cheat’’ for special occasions, like a great grandchild who wants me to share his/her birthday dinner, but I am very happy with all suggestions here!!!
