A 14-year-old Norwegian teen was hospitalised with kidney failure and slipped into coma after drinking four litres of a caffeine-laced energy drink during a marathon 16-hour computer games session.
Henrik Eide Dahl collapsed in the cafeteria of his school at the end of a group gaming session, played on computers linked together on the school's Local Area Network.
"I was playing Call of Duty. Then everything went dark and I passed out," Dahl told Norway's NRK network.
The teen was flown to hospital in Lillehammer, where his condition worsened, with his kidneys starting to fail. After he fell into a coma, he was kept alive by a respirator and a drip.
He spent a total of 13 days in hospital, and is still taking medication to control his high blood pressure, 'The Local' reported.
Anne Kathrine Duns, a doctor who treated him in Lillehammer, said that Dahl had been close to death.
"It was severely life-threatening. The central nervous system, cardiovascular system, lungs and kidneys were affected," Duns said.
She said that despite several tests, it remained uncertain as to what exactly had caused Dahl's collapse, although she said she suspected the energy drink played a role.
"We find no underlying disease in Henry, so for now we are attributing this to the consumption of large amounts of energy drink," she said.
