Binge Eating Tops Other Eating Disorders: Survey

"These results back up things that groups like ours have been saying for the past several years," said Marc Lerro, executive director of the Eating Disorders Coalition. "There has been relatively little definitive research done on eating disorders."

Lerro is happy to see that these conditions are getting more recognition. "People with eating disorders are compromised in how they interact in school, in the workplace," Lerro said. "For some, it's really a disabling condition that sometimes leads to death."

That binge eating is the major problem did not surprise Lerro. "The stereotype that [people with] eating disorders are just pencil-thin girls is really not comprehensive," he said.

Lerro believes the federal government should be keeping track of the number of people in the United States who suffer from eating disorders. This year, the U.S. government is spending only $21 million on research into treatments for eating disorders, he said.

"This survey is really a wakeup call for the federal government to do more, like counting the number of people who die each year due to an eating disorder, counting the number of people who are struggling with eating disorders, and funding research to determine what is effective in treating eating disorders," Lerro said.

Another expert believes that eating disorders are even more common than the survey suggests.

"Eating disorders are more common than many people realize, and the prevalence is increasing," said Dr. Ellen Rome, head of the section on adolescent medicine at the Cleveland Clinic. "If you look at all of mental health, the spectrum of eating disorders is among the most commonly found health challenges that individuals face."

Moreover, people with eating disorders also have many social problems related their condition, "from shame, guilt, denial, the egocentricity of the illness that doesn't let them see how it's affecting their lives," Rome said.

Binge eating is closely tied in with the U.S. obesity epidemic, Rome added. "We see any form of disorder eating as a maladaptive coping strategy," she said. "Eighty percent of obesity is genetic. So, genetics loads the gun. And the prevalence of binge eating goes hand-in-hand with obesity as one contributing factor. Many people use binge eating to fill up an empty space."

Rome also believes that more funding is needed to study the causes and treatments of eating disorders, including the genetic and social components of the problem and what treatments work best.

"We are just scratching the surface," she said. "We need better treatments across the whole spectrum from under-eating to obesity. There is just so much more we need to know."
