Amy Winehouse's death caused from eating disorder (FILES) - Picture taken on June 28, 2008 shows British singer Amy Winehouse performing at the Glastonbury Festival at Worthy Farm, in Glastonbury. The life of late British singer Amy Winehouse is the focus of a new play opening in January at the Danish Royal Theatre in Copenhagen, the theatre said on October 24, 2012. BULIMIA killed British singer Amy Winehouse, according to her brother. THE singer died from alcohol poisoning in July, 2011. She was 27. Now her brother, Alex Winehouse, has spoken out about his sister's death, and declared an eating disorder was actually to blame for the tragedy. Alex Winehouse claims the singer struggled with bulimia since she was a teenager, and the condition left her body in a weakened state, more susceptible to the dangers of alcohol. She suffered from bulimia very badly. That's not, like, a revelation - you knew just by looking at her," he told Britain's The Observer newspaper. He said he was convinced that his famous sister would eventually succumb to the eating disorder. She would have died eventually, the way she was going, but what really killed her was the bulimia ... Absolutely terrible. I think that it left her weaker and more susceptible. Had she not had an eating disorder, she would have been physically stronger," he said. Alex Winehouse also reveals his sister first began suffering the condition when she was in her teens, and she used to hang around with a group of girls who all fell victim to bulimia. (They) were all doing it. They'd put loads of rich sauces on their food, scarf (eat) it down and throw it up. They stopped doing it, but Amy never really didpe``We all knew she was doing it, but it's almost impossible (to tackle) especially if you're not talking about it. It's a real dark, dark issue.
