And my nephrologist is pushing the salt and protein where others are limiting them. I think it depends on what the docs think is behind changes in the GFR.

Hi, I was in your situation 3 yrs ago. The effect of having only one kidney after a removal of my left kidney due to cancer, got my blood levels unstable. So I was diagnosed with stage 3 kidney disease. My only consolation then was taking in water to lower my creatinine level. But that’s not the only source. So I went to see a renal dietician who has guided me through all this every 4 mons. My diet mainly consists of fish, some shellfish and veggies limited salt and a regular walking exercise.
It has improved and stabilized my egfr, creatinine and almost all other vital labs, my blood pressure and diabetes. Most esp I stopped eating prepared food that had lots of phosphorus which are not indicated in the nutritional value of the products.
Do not be alarmed. See your nephrologist with lab tests every 4 months because that what’s going to guide the dr, the renal dietician and most esp you and going about your life as normal as possible.
I’m learning to eat chicken which I’m only familiar as fried chicken. So now I cook chicken with some veggies and enjoy it in between fish dishes.
Do not be afraid because feeling that way affect your kidneys too. Ease up your life be more relaxed so your blood pressure is stable too.
Hope this can lighten you up.
