Experts debate making binge eating disorder official
It’s estimated that anorexia affects about one percent of the U.S. population and bulimia 4 percent. Binge eating disorder eclipses both, affecting about 10 percent of the population but it has yet to be recognized as a diagnostic eating disorder unto itself. Despite the vast range of eating disordered behaviors, there are exactly three disorders one can be classified with: Anorexia nervosa, Bulimia, and Eating Disorders Not Otherwise Specified (ED-NOS). Binge eating disorder falls into the latter category, a vague catch-all diagnosis for people who don’t fit one or more of the criteria for anorexia and bulimia. Those classified with ED-NOS can range from a morbidly obese binge-eater to a 90-pound girl who meets every criteria for anorexia, except she still menstruates.
That might soon change. According to the New York Times, panels of psychiatrists are in the process of updating and revising the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-V). The current edition of the manual, the DSM-IV, was published in 2000. The manual’s importance cannot be overstated. It’s used by doctors to make a diagnosis and provides insurance companies with diagnostic codes without which the insurers will not reimburse patients’ claims for treatment. Conditions now up for debate to be added as official diagnoses include compulsive shopping, gender identity, conditions affecting children, sensory processing disorder and also binge eating.
The American Psychiatric Association publishes the manual and according to the Times, the process has become such a contentious exercise that for the first time the APA has required its contributors to sign a nondisclosure agreement. Those scientists who accepted an invitation to work on the new manual, a prestigious assignment, agreed to limit their income from drug makers and other sources to $10,000 a year for the duration of the job, so as to better insure that pharmaceutical perks don’t unduly influence the authors’ decisions.
The fact that binge eating disorder is up for consideration is certainly encouraging news, but it’s not yet a done deal. There are some mental health experts who don’t think that it should be classified as a disorder at all. Dr. Michael First, a professor of psychiatry at Columbia who edited the fourth edition of the manual but is not involved in the fifth, is among them. As quoted in the Times article:
“A lot of people want that included in the manual,” Dr. First said, “and there’s some research out there, some evidence that drugs are helpful. But binge eating is also a normal behavior, and you run the risk of labeling up to 30 percent of people with a disorder they don’t really have.”
Frankly, I don’t understand how experts like Dr. First recognize bulimia as a legitimate mental health disorder and not binge eating disorder. Sure, binge eating in itself can be a natural, non-disordered behavior — food eating competitions are just one example, stuffing oneself beyond fullness at Thanksgiving is another — but like all eating disorders, binge eating disorder is about much more than food. The generally accepted criteria for it reads similar to that for bulimia, except people with binge eating disorder don’t try to rid themselves of the extra calories through self-induced purging or exercising. Otherwise, the psychological anguish and emotional torment is much the same. In addition to psychotherapy, there are medications that have been shown to help people with binge eating disorder (Topamax and Wellbutrin, for example). If binge eating disorder were included in the manual as a legitimate eating disorder, those people who struggle with it might have an easier time getting insurers to cover the treatment and medication they so desperately need.
In any case, the fact that binge eating disorder is up for serious consideration for inclusion in the new manual is encouraging. As noted, psychiatrists involved in the new manual are under a gag order, but they also say that its too soon for them to have made any concrete decisions. The book is still at least three years away from publication, so only time will now tell.
