In an interview for the British newspaper Daily Mail, Mitch Winehouse said that his daughter, Amy Winehouse, has serious lung problems.

Amy Winehouse, who was taken to the hospital last Monday, after she briefly fainted underwent several tests this week, but the doctors did not reveal any information about her health status.

However, there were rumors in the British media, according to which the doctors warned Amy Winehouse that her drug addiction could be fatal.

Mitch Winehouse, who took her to the private London hospital The Clinic, said today that the doctors said Amy Winhouse has early stage emphysema.

Emphysema is a progressive lung disease that results in shortness of breath and reduces the capacity for physical activity. The cause of emphysema is damage to the small air sacs and small airways in the lungs. This damage obstructs airflow when one exhales.

The doctors said Amy Winehouse could be confined to a wheelchair within a month if she doesn’t quit drugs. Also, they warned she may be forced to wear a permanent oxygen mask to survive if she doesn’t follow medical advice.

“But the doctors have told her if she goes back to smoking drugs it won't just ruin her voice, it will kill her”,  Mitch Winehouse said.

In an emotional appeal, Mitch Winehouse begged her drug dealers to stay away from his daughter.

“I'm saying to those drug dealers, and they know who they are, if they are supplying crack to Amy, then they've got to take responsibility,” he said. He also spoke about Pete Doherty, the leading singer of the British group Babyshambles, who is known for his drug addiction,

“I don't want her hanging out with her mates like Pete Doherty either,” Mitch Winehouse said.

Due to her health problems, Amy Winehouse will probably miss her scheduled performances at Nelson Mandela’s birthday concert on June 27 and at Glastonbury festival on June 28.

Earlier this week, Amy Winehouse spokesperson said that a decision about her future performances will be taken and the doctors will announce the results of the tests.

However, her father said Amy Winehouse is ready to kick her bad habits and turn her life around.

Last year, the British singer was admitted to a hospital in London suffering from "severe exhaustion". Earlier this year, the singer checked herself into a rehabilitation clinic, after a video showing her taking drugs emerged in the media.
