I'm a bit surprised that your doctor told you not to worry since you seem to be doing okay. I don't mean to offend you but are you being aware of all the salt, protein, phosphorous, magnesium and potassium you are taking in each day??? I am trying my best to keep track of these things. I do still have some questions but I will just look these foods up online. I have CKD3 and my last GFR number was 49 which went up from 44. I don't get another blood test until August. I still have to be aware of how much sugar and fat I consume. It's not easy because you don't get much flavor when you take out the salt from foods, such as kidney beans, tuna, etc. I hope this helps you in some way. Good to hear that your kidney is doing well but I would still be careful about your daily intake of food. Best of luck!! Nancy
