@zeppo There is a natural decline in kidney function as we age, just like all the organs. My dad lived to age 95, his mind was very sharp, but his body got tired.

You mentioned blood pressure and diabetes, which are two of the biggest causes for kidney disease. There are also hereditary factors, some long-term medications, and lifestyle. As you have found, dietary awareness plays a big role no matter the health issue. Glad you found a path that works for you!

I am ten years older than you, and just had a similar shock. My healthy lifestyle and eating choices, and being a vegetarian, left me shocked with the diagnosis. Mine is attributed to a 6 year span of taking Bactrim - which kept me alive. No one suggested a kidney scan. I am terrified. I am interested in any comments from people who have been able to lower their GFRs. Mine is 51, not too bad, but I don't want a life of progressive kidney failure and all it entails, especially for my family. The only hope I see is diet.

So far, I have had to fight the entire way. The original kidney specialist I saw did not even bother to mention diet. SO I have become more aggressive than is my nature.

I read all the advice on here from those of you who have raised their GFRs.
