Utah Jazz general manager Justin Zanik revealed he's been dealing with a serious health condition .... admitting he was in kidney failure after he was diagnosed with a disease that left only 14% of the organ's function.
The 49-year-old went into detail about the discovery on Monday ... explaining his wife, Gina, was concerned that he looked thinner and tired -- so she begged him to get a physical after missing the last eight annual exams.
Zanik -- who became the NBA team's GM in 2019 -- set up an appointment with the Jazz physician David Petron in September 2023 ... and was told he was in kidney failure.
The diagnosis is Polycystic Kidney Disease -- an inherited disorder where cysts develop on the kidneys causing them to work less -- and Dr. Petron said Zanik only had 14% of the kidney's use left.
Zanik will have to get a transplant -- something his father did 21 years ago ... and he found a match with his wife's best friend's husband. The procedure will happen on Tuesday.
"I'm a fixer by nature. My job with the Jazz, my role with my family -- I mean, I was a [player] agent for 15 years. I fixed a lot of s***. I'm the one who's supposed to help," Zanik said.
"I'm the one who's supposed to take care of everything. I really didn't know how to ask for help, but I had to get over it. I knew I had to get over it."
Zanik's children were also diagnosed with advanced forms of PKD ... and were told that Ava, Oskar, and Lucy would need transplants before they were 30 years old.
"We're going to do this together," Zanik said. "We're stronger together."
Zanik will stay at the University of Utah's hospital after the surgery to monitor the kidney and recover at home for the rest of the month.
