The former England star, 48, was described by guests as “paralytic” when he checked in for a pre-Christmas stay, reports The Sun.
He then tried to order more alcohol but was refused before staff found him “slumped over and stinking of booze” in the early hours.
Blood was pouring from a cut to his hand where the star had fallen on a glass.
Gascoigne was then rushed to hospital at 5am in what was called a “medical emergency”.
One guest told the newspaper: “I have never seen a human being so utterly obliterated by alcohol.
“It is so sad. He looked like a little old man.”
Gazza, who has spent years battling alcoholism, arrived by cab at Champneys Forest Mere in Liphook, Hampshire, at 8pm on Friday. He was due to stay until December 23 and was led to his room by concerned staff.
Gascoigne, who is said to have just left hospital after treatment for a bladder infection, then called room service to order more drink. Staff refused and sent up some food instead.
Later, a night porter went to check on the former Newcastle United player but found him collapsed. Staff then called an ambulance.
A spokeswoman for the South East Coast Ambulance Service said: “We attended a call at 5am to a medical emergency in Liphook, Hampshire. A man in his 40s was assessed and taken to hospital.”
