Kadeena Cox's 'I'm A Celebrity... Get Me Out Of Here!' campmates had to help her get to the toilet at times during the series because her multiple sclerosis was so bad.
The Paralympian has admitted she "really struggled" on the ITV show on occasions because of her MS, which meant she had to be helped into bed and her spasms were "quite a problem" at times.
She said: "I thought my MS would be nice to me.
"Turns out MS is never nice to you, so I really struggled with the fatigue and my spasms were being quite a problem, and there was points where my speech was really slurred and everyone was really worried about me.
"There was times when literally the campmates had to help me get into bed, they had to help me get to the toilet, and it was a real struggle."
However, the 30-year-old star admitted she developed a "strong" bond with her campmates thanks to them helping her out.
She said: "In those really vulnerable moments I realised how strong my bond was with the campmates and how loved I was.
"We just laughed our way through it."
And despite her MS struggles during the series, Kadeena tried to only focus on the positives of the experience.
She added to The Sun newspaper: "MS is really up and down but I wanted to really enjoy the experience and not focus on the negatives of my condition."
Kadeena departed the show on Monday night (06.12.21), and she admitted finding the show tougher than she expected it to be.
In her exit interview, she told hosts Ant and Dec: "If you're scared of everything you're kind of not going to survive very well, so I wanted to push my boundaries.
"I thought it would be a lot easier than it was. I guess I've just learned to deal with my condition at home so I thought yeah I'll be fine, I'll show other people with MS and chronic conditions we can do this.
"It was harder than I thought but I think I showed that even with these trials and tribulations of just life as someone with a chronic condition, you can still crack on and have fun."
