I also had a kidney disease and I thought I'd share what my doc recommended and helped. I don't have high blood pressure nor am I a diabetic which is what usually people have that have a kidney disease. So my doc put me on a planet based diet for 3 months. She said "don't eat anything that has a "mother" as in any kind of meat, milk, butter, eggs etc. Only eat fruits, veggies, whole grains, nut, and seeds, and legumes. I also had to have oatmeal every morning. After 3 weeks of being on this I had to go to emergency room for acute stomach pain, turns out I had diverticulitis . They did blood work and I could not believe how my kidney numbers went up to normal. Along with the plant base diet I took Doterra Zendocrine Detoxification Blend soft gels and Zendocrine Detoxification Complex, which my doc approved of. Doing both helped me to get my kidneys back to normal. Lately I have been swaying away and cheating too much so my numbers are going down again. I'm going back to doing what I need to do. Just thought this might be of help to you.
Blessings....
