Winehouse has emphysema, says dad

Amy Winehouse is suffering from the early stages of lung condition emphysema, her father Mitch has revealed.

The singer has been undergoing tests at a private hospital in London since collapsing at home on Monday.

"The doctors said that if she had continued the way she was going she could have ended up an invalid - she wouldn't have been able to breathe," said Mitch.

"She's got emphysema. It's in its early stages, but had it gone on for another month they painted a very vivid picture of her sitting there like an old person with a mask on her face struggling to breathe. With smoking the crack cocaine and the cigarettes her lungs are all gunked up."

Mitch said Amy has to give up drugs and stay away from her drug-using friends, but may still sing at this week's Glastonbury Festival.

"She abstains and regulates her drug use when she has to do a show," he told the Sunday Mirror. "When she's been inactive work-wise then that's when the problems really start. The doctors have said that medically there isn't any reason why she can't do Glastonbury."
