Diet plays a huge roll in how one handles dialysis...Phosphorus, Potassium, Sodium, and liquids (40-60 oz between treatments?) should all be restricted...I'm not even going to try to list all the things that is on our restricted or avoid list, because it's just too long. Anyone that has been on dialysis knows it's probably easier to list the things you CAN eat than what you shouldn't.Also I'd point out that things like ice cream, pudding, jello, popsicles, etc...(stuff that is liquid at room temp) would be considered part of her fluid intake.Wherever she dialyzes they should have a dietitian that has explained or should explain all of this all to her...Here is a link that might help understand what is restricted and why...it also has a link to find dietitians in your area:http://www.medicinenet.com/script/main/art.asp?articlekey=78054
