An anti-eating disorder organization is calling on the U.S. Food and Drug Administration to rescind approval of a device because it is "unsafe" and will encourage people with eating disorders to engage in dangerous purging behavior, they say.

The FDA recently approved AspireAssist, a device implanted in the stomach that enables people who are severely obese to drain the contents of their stomachs into the toilet about a half-hour after eating.

Earlier this week, the Academy for Eating Disorders (AED) joined with other obesity specialists in criticizing the device, which they say provides a mechanized form of the eating disorder, bulimia nervosa.

"Such a device may carry very serious physical and mental health consequences, including life-threatening situations, and should not be approved by the FDA,” says Dr. Eva Trujillo, the organization’s president.  "This will likely prove to be yet another in a long list of misguided, unsuccessful, and dangerous products for losing weight," she added.

Although the FDA has stipulated the device is not intended for use by people with eating disorders, Trujillo called this “woefully inadequate,” and adds that her organization has  “grave concerns” that the FDA would device approve such a device for anyone seeking weight loss.
