At least according to this editorial in the American Journal of Psychiatry, exploring the question of whether to make obesity a brain disorder in DSM-V.
Of course, it's not really clear what exactly they mean by brain disorder. Anorexia and bulimia are listed in DSM-IV as brain disorders, sorta, and I have to say, I'm not sure what that means, either. Insurers still treat them as mental health issues rather than biologically based illnesses, and use that as a way to skive off covering them (at least in beknighted states like Wisconsin, which have no mental healthy parity laws).
It depends what the rationale is here, really. What we now know about eating disorders like anorexia is that some people are genetically and biologically predisposed to them, and that environment seems to play some kind of role in triggering those who are susceptible. Maybe that's true for obesity. That makes more sense to me than suggesting that all so-called obese people are compulsive eaters, which we know ain't true. Yo-yo dieting might be the environmental trigger, resetting the metabolism over time in ways that result in obesity.
But if an entry in DSM-V is going to result in more stigma attached to being obesity, I think we should say no thanks.
What do you think?
