Gascoigne was admitted to an intensive care unit over the weekend after he suffered complications while receiving treatment for his addiction to alcohol in a clinic in Arizona. The former Tottenham, Newcastle, Rangers, Everton and Lazio midfielder has battled alcoholism for large parts of his life and he was admitted to the specialist clinic following his latest relapse.
Barton, who has also experienced troubles related to alcoholism in the past, posted on Twitter: "The alcohol abuse will kill him. The prescription drug addiction and the addiction to the limelight and not having it anymore, r major issue(s). If those well meaning souls get this wrong he will be dead within the year."
He added: "That's the reality. All thise (sic) that have tried to love/help him... down the years. Have done so with the greatest intentions, not all but some.
"And look at the man now. He needs professional help and the... privacy to recover. Not doing interviews an having the media follow him."
Gascoigne is thought to have spent Sunday night in hospital, and is said to be making good progress in his recovery.
Gascoigne's long-term psychotherapist Dr John McKeown played down any fears about the 45-year-old's long-term health on Sunday.
"The hospital has reassured me that he is up and about walking," he said. "Paul has experienced severe complications with his detoxification.
"This is not unusual for someone who has been drinking as heavily as he has. Paul was transferred from the US Clinic Cottonwood to a local hospital to be monitored so as to be completely satisfied that there are no other complications to his health.
"There are no fears for his life. We will aim to keep everyone concerned updated on a regular basis."
