The high prevalence of eating pathology prior to bariatric surgery reduces the likelihood of what researchers have termed “optimal” weight loss post surgery. However, such weight loss is in part due to post-surgical complications like “dumping” (rapid gastric emptying because digestive systems cannot process the food) or vomiting that can develop into conscious efforts to lose weight. Conceicao et al. (2013a) describe, for example, one patient who deliberately binged and purged on foods that would make her vomit spontaneously.
These kinds of results raise a number of questions:
- How prevalent are eating disorders (EDs) post-bariatric surgery?
- What are the risk factors for developing an ED?
- To what extent is the surgery itself a potential trigger?
PREVALENCE OF DISORDERED EATING AMONG INDIVIDUALS SEEKING BARIATRIC SURVERY
Researchers interested in bariatric surgery have explored how often those seeking bariatric surgery engage in disordered eating or have EDs. Prevalence rates vary between studies depending … Continue reading →
Is ED recovery easier when your body is “normative or stereotypically desirable”? The anon asking the question implied that recovery could be more difficult because “an obese person … will never stop hearing hearing extremely triggering stuff about their body type.” Anon asked, “Have there been any studies on this?” Andrea tackled this question in her last post (it might be helpful to read it first if you haven’t yet); in this post, I will expand on my original answer.
Assuming anon meant, “Have there been anything studies assessing whether recovery is harder for individuals who do not fit the normative body type (because of fat phobia/fat shaming/diet culture)?” Then, my answer is: Not really, or at least I couldn’t find anything evaluating this question directly.
I was only able to find a few studies commenting on the history of overweight or obesity as a predictor of recovery/treatment … Continue reading →
Although the words “anorexia nervosa” typically conjure up images of emaciated bodies, eating disorders characterized by dietary restriction or weight loss can — and do — occur at any weight. However, precisely because anorexia nervosa is associated with underweight, doctors are less likely to identify eating disorders among individuals who are in the so-called “normal” or above normal weight range, even if they have all the other symptoms of anorexia nervosa.
Clearly, this is a problem.
For one, there is no evidence that eating disorder not otherwise specified (EDNOS) — a diagnosis given to individuals who do not fulfill all of the criteria for anorexia nervosa or bulimia nervosa — is less severe or less dangerous than full syndrome anorexia nervosa. As I’ve blogged about, individuals with EDNOS have comparable mortality rates (see: EDNOS, Bulimia Nervosa, as Deadly as Anorexia Nervosa in Outpatients) and similar (sometimes even more severe) … Continue reading →
Advertisements bemoaning the evils of obesity, begging us to eat healthier and to exercise, surround us every day. Big corporations and governments alike have jumped on the anti-obesity bandwagon, crafting public service announcements aimed at correcting what is being framed as an epidemic. For many, these messages are likely generic reminders to strive for health, if they are noticed at all. But what about individuals with eating disorders? A recent (2012) study by Catling & Malson (full text available here) looked into how a group of women with a history of disordered eating interpreted anti-obesity messages.
I was particularly drawn to this article, having personally felt rage at some of the overly simplified messages that circulate around obesity and “health.” Particularly when I was early in recovery, I often felt as though I was swimming against the current in my attempts to do just the opposite to what these … Continue reading →
The recent New York City soda ban controversy has contributed to increased discussion about the “addictive” properties of sugar and its contribution to the obesity epidemic. While I do not deny that there is an overabundance of high-sugar/high-fat foods in the societal milieu, and that the rewarding properties of these foods encourages their overconsumption; I think it is a mischaracterization to refer to the typical overeating associated with the “obesity epidemic” as reflective of a widespread “sugar addiction” that millions have fallen prey to.
Stice, Figlewicz, Gosnell, Levine, and Pratt (2012) have recently released a review in Neuroscience and Biobehavioral Reviews entitled “The contribution of brain reward circuits to the obesity epidemic.” In the paper, the authors elegantly describe the overlap between food and drug rewards while also highlighting major differences.
BRIEF INTRO TO DOPAMINE SIGNALLING
Before discussing the parallels between food and drug rewards, we should first introduce some … Continue reading →
