Kamara, who has become a cult hero due to his charismatic work on football programmes including Soccer Saturday, told The Sun that he has been invited by ITV to join the show.
The 64-year-old said: "I think I’m too old now. So, the one thing I don’t want is when they do a challenge to try and win food for the camp and they say: 'Unfortunately, Chris Kamara can’t do tonight’s challenge, because of his illness'.
"Yet why did you go in there in the first place if you can’t do a challenge? So it's maybe not for me anymore."
Kamara would be far from the oldest contestant to appear on I'm a Celeb, with Arlene Phillips holding the record — aged 78 when she took part in the 2021 series.
That series, however, took place in Wales due to the COVID-19 pandemic, with 77-year-old Stanley Johnson becoming the oldest star to head to Australia with his appearance in the 2017 series.
Culture Club singer Boy George is the oldest participant on this year's series at 61, ahead of 59-year-old Coronation Street actor Sue Cleaver.
Kamara played more than 600 games at club level in a 20-year football career, including stints at Swindon Town and Brentford.
After a brief attempt at management, he moved into broadcasting and became a stalwart for Sky Sports on the weekly Soccer Saturday show.
He has since spread his TV career further and now presents Ninja Warrior UK for ITV with Ben Shephard and Rochelle Humes.
In an interview with the Diary of a CEO podcast earlier this year, Kamara revealed that he has been diagnosed with apraxia of speech.
The condition has caused Kamara to step back from a lot of his presenting work, with the star revealing that he "[feels] a fraud now in terms of broadcasting".
He added: "It feels like someone has taken over my voice box. The voice that used to come out would come out at 300 miles an hour, you’ve seen me on the results and Soccer Saturday, motormouth, talking and not even waiting for a breath, just keep going and going.

"Now when I hear myself or see myself on TV, it’s someone else. It’s really strange."
Kamara is set to explore the impact of his condition alongside Ninja Warrior co-host Ben Shephard in the upcoming ITV documentary Chris Kamara: Lost for Words.
