GettySuni Lee -- the Olympics star who won gold in Tokyo in 2020 -- just revealed her kidney issues this year caused her to gain 45 pounds.
The 5-foot gymnast made the revelation in an interview with USA Today this week ... just a few months after she left Auburn to get a handle on the ailment.
"I couldn't fit into any of my clothes," Lee told the outlet. "My eyes were swollen shut. It was just so scary."
Thankfully, Lee says she's doing better now ... and, according to USA Today, she looks "very much like the gymnast" who competed in the Games nearly three years ago.
Getty"I haven't had a really bad day in a while," Lee said. "But in the beginning it was like I was waking up swollen. My fingers were so swollen they wouldn’t fit into my grips and I couldn't hold on to the bar."
She added, "My whole body was swollen because I was retaining water, so I couldn’t do a flip. … So it was really different and I had to learn how to work through it."
