If all other health parameters are okay check out Barefoots kidney formula. I'm sure he's got some great stuff for the kidneys.
Also check out reprograming your genetic makup. Sounds crazy but Cooper of aerobics fame has been having great success with congenital genetic predispositions. Actually changing the DNA code so the next family member isn't suseptable to the parents genetics.
Yes, it's doable. Simply a matter of changing your mind. Quit believing all the crap the so-called "experts" are craming into your head. Spirit IS above matter. You ARE above genetics.
