A Case Against Eating Disorder Not Otherwise Specified (EDNOS)

This will be a short entry, really just a follow up on the findings mentioned in the last entry. In particular: the issue of EDNOS, transitions between eating disorders and how the DSM should be changed to reflect the clinical reality of eating disorders (and what is the clinical reality?). I do not want to repeat myself here, so for an introduction to these issues, please see my last entry.

In this study, Eddy et al followed 246 women who were initially diagnosed with either AN or BN, for an average of 9 years. The main goal was to study the growing disparity between (1) the consensus that eating disorders are not stable overtime and how (2) the current diagnostic criteria which do not adequately address this, by following the clinical presentation of EDs overtime and providing suggestions for the upcoming DSM-V.

I am a lazy purger. When I was younger and thinner I would throw up everything I ate without fail, and as soon as I had eaten it. I do it now when I feel full or unhappy with myself, so it is often acidic and unpleasant coming up, and I have been wondering recently just how effective vomiting is, in regards to weight loss. Clearly it is not particularly effective as I do it perhaps five or six times a week but am still overweight, but then I tend to do it to reduce the feeling of fullness, as opposed to weight loss. I am not too bothered really, but I would really like to know the biology behind it.

We get the therapists promising us 'purging is utterly ineffective', but I don't think this can be true. Purging anorexics for example must be getting rid of at least some of the calories. Then there is the fact also favourite among therapists of 'digestion begins in the mouth, you know' but I think they don't realise that this means the breaking down of food (chewing), rather than intake of calories.

What are your thoughts? I do wish to lose weight, but I certainly do not wish to do so via throwing up, so please note that this post is for education purposes, and not for aiding with my eating disorder.
