The former Newcastle, Tottenham and Lazio star, who has battled drink and drug addiction since he retired from the game nine years ago, broke down while giving a speech at a charity event on Thursday.
Gascoigne had recently been receiving help at the Providence Clinic in Bournemouth which, in 2011, he claimed changed his life for the better but this latest episode has put his life at risk.
Terry Baker, his agent, told BBC Radio 5 Live: "He won't thank me for saying but he needs to immediately get help.
"His life is always in danger because he is an alcoholic. Maybe no-one can save him - I really don't know"
"He's been absolutely fine, he really has, and now he isn't - but I think he knows that.
"His life is always in danger because he is an alcoholic. Maybe no-one can save him - I don't know. I really don't know."
On Saturday Gascoigne was offered a help and assistance by former England team-mate Tony Adams, also a recovering alcoholic who runs the Sporting Chance Clinic.
A clinic spokesman told the Sunday Mirror: "Tony and the charity continue to offer treatment for addictive disorders including alcohol.
"We work very closely with the Professional Footballers' Association, who have always supported any player who has asked."
