@alive It can be a challenge to preserve as much function as possible. When you go over to the Kidney and Bladder support group, you will find discussions about working with impaired kidney function. Getting optimum results to maintain function, a person has to be very mindful about sodium, calcium, potassium, and phosphorous. And then there is the daily fluid intake, and appropriate protein intake for the kidney levels. It's quite the challenge. I hope your niece is being followed by a great nephrologist and renal dietician! Addressing the underlying cause of the kidney issue will also be a benefit.
