The chair of the Digital, Culture, Media and Sport Select Committee has called for an "urgent review" into how TV companies look after reality show guests.
Conservative MP Damian Collins said a "proper independent review" was required into the duty of care policies carried out by shows which put "anonymous, private citizens" in the spotlight.
His comments follow the news that The Jeremy Kyle Show has been pulled from airing indefinitely after a guest died shortly after recording the show.
"There needs to be an urgent review of the sort of duty of care policies The Jeremy Kyle Show has in place, and that other TV companies have in place over reality TV shows," Mr Collins told talkRADIO's Julia Hartley-Brewer.
"These shows often feature quite vulnerable people. They are people that have come from private life to suddenly being thrust onto television."
Hampshire Police have confirmed that Jeremy Kyle show guest Steven Dymond, 62, was found dead on May 9, but his death is not being treated as suspicious.
Mr Dymond's landlady claimed he had returned from filming the show "sobbing and distraught" after failing a lie detector test, the Daily Mail reported.
"It is not unreasonable to say I think the people that are making the programme, making the money out of programmes, have a duty of care to the people they feature on their shows," Mr Collins continued.
"People are being used as a form of entertainment. Out of that they get short-lived celebrity, but what is the actual impact on people?".
