A man who took an overdose of morphine after being a guest on The Jeremy Kyle Show was "very upset" after his appearance, an inquest has heard.
Steve Dymond, from Portsmouth, is thought to have taken his own life seven days after filming for the ITV programme in May 2019.
The 63-year-old took a lie detector test for the show after being accused of cheating on his ex-partner, Jane Callaghan.
His son Carl Woolley told the inquest in Winchester his father felt he had been "cast as the liar".
Mr Woolley said he and his father had not been in recent contact before his uncle Leslie Dymond rang to say his father was "very down".
He told the inquest his father said the "lie detector had cast him as a liar, he said to me he wasn't lying".
He said his father told him he had been "telling the truth".
He added Mr Dymond "was very upset saying he was being called a liar, everyone had jumped on him, (he was) not with it at all".
When asked by counsel to the inquest Rachel Spearing who had "jumped on him", Mr Woolley replied: "Jeremy Kyle had got the crowd to egg on, to boo at him and stuff, he was cast as the liar before he had even spoken."
Mr Dymond died of an overdose of morphine and a heart problem at his home in Portsmouth, the inquest was told.
The hearing continues.
