Anyone who might advise you to compete while you have zero kidneys is not someone you should be near.
Zero kidney function and Dialysis is a serious condition, you are not too far from death at any one time. DAs heart stopped twice whilst plugged in, if the machines are not cleaning you up enough you're walking on very thin ice, so why on earth would you train harder, which increases toxins extretion, eat more which increases body waste and body weight meaning more mass to clean up and higher BP....etc. Seriously it has to be the stupidest thing ever.
