When Leo was first diagnosed with kidney failure, his doctors weren’t sure if it was an infection from surfing—his passion—or something else. The antibodies in his body had damaged his kidneys and Leo began in-center dialysis treatments. But in-center treatments made him feel like he had lost control of his life, as it became dictated by treatment schedules. He was not living the life he wanted to live. While his wife was skeptical, Leo was convinced that home hemodialysis with System One was the solution. System One allowed Leo to go from feeling like a little old man sitting in a room with a blanket over him to a man who just taught his granddaughter to surf. Leo surfs almost every day and is back to doing everything he used to do before kidney failure.
