Wow, how long was your mom on the list for transplant. It's obviously genetic since you know you will go through Kidney failure at some point. At least you are doing what you can to push it off as much as you can.Yes its a tough road because the kidney has like 8 vital functions. I know because Im facing kidney failure in the future and do cardio 6 times a week to fight off fluid retention from permanent blood pressure pills, my mom just got her kidney and liver transplant only 4 weeks ago. Im sorry for your friend.
