The man - Steve Dymond, 63 - is thought to have taken his own life after failing a lie detector test, which he hoped would prove he hadn't been unfaithful to his partner.
The footage will never air and ITV has suspended both filming and broadcasting of the show.
Jeremy has since spoken out, saying, “Myself and the production team I have worked with for the last 14 years are all utterly devastated by the recent events. Our thoughts and sympathies are with Steve’s family and friends at this incredibly sad time.”
ITV then confirmed the programme was being axed.
Head of the network Dame Carolyn McCall said in a statement: “Given the gravity of recent events we have decided to end production of The Jeremy Kyle Show.
“The Jeremy Kyle Show has had a loyal audience and has been made by a dedicated production team for 14 years, but now is the right time for the show to end.
“Everyone at ITV’s thoughts and sympathies are with the family and friends of Steve Dymond.”
Jeremy told The Sun: “Myself and the production team I have worked with for the last 14 years are all utterly devastated by the recent events. Our thoughts and sympathies are with Steve’s family and friends at this incredibly sad time.”
This isn't the first time the morality of reality TV has raised questions.
In a Sunday Night exclusive - which you can watch above - former MAFS bride Clare Verrall speaks out about her time on Married At First Sight nearly resulted in her taking her own life.
