Why do some people recover anorexia nervosa relatively quickly while others seem to struggle for years or decades? Does it depend on the person’s desire to get better? Their willpower? How much they are willing to fight? Is it just that some try harder than others? Some might say yes, but most will correctly realize that the picture is much, much more complex.
We can spend hours talking about barriers to treatment, but in this post I want to talk about something slightly different, something perhaps that is perhaps less “obvious.”
Suppose a group of girls–all roughly the same age, same illness duration, same socioeconomic background and race–enter the same treatment facility. What determines why some will do well in treatment and continue to do well after discharge, whereas others will relapse immediately after discharge, and yet others won’t respond to treatment at all? We know that catching eating … Continue reading →
Excessive exercise (EE) is common among eating disorder patients. Indeed, in the study I’ll write about today, 39% of patients engaged in EE. Previous studies have tried to find psychopathological and personality correlates of EE but the results have been inconsistent. Some studies have suggested that impulsivity and addictiveness are highly correlated with EE whereas others found that anxious and depressive traits were more closely associated.
In a retrospective case series study involving outpatients with AN and BN, Penas-Lledo et al. found higher levels of anxiety and depression… among those who were identified as exercising excessively. The authors claimed that exercise might serve to reduce anxiety and stress in individuals with AN. In a similar study with adolescent inpatients with AN, Holtkamp et al. found that anxiety significantly predicted variance in exercise levels. These investigators proposed that anxiety symptoms in combination with food restriction contributed to increased levels

Anonymous asked, “I’ve never lost my period. Weight restored I am naturally thin, but even at a BMI of 15 or so I always got my period (although it wasn’t always regularly). This makes me feel like I’m not actually sick because I hear about everyone losing their period.”
eatruncats replied: “To the anon who asked about losing periods: For all the times she worries about not being sick enough because she never lost her period, there are people who lost their periods at BMIs of 18, 19, and 20 who worry about not being sick enough because they never got to a BMI of 15. If you have an eating disorder, you are “sick enough.” Period.“
As it stands now, amenorrhea–or the loss of three consecutive menstrual cycles–is a diagnostic criterion for anorexia nervosa. Individuals who have not lost their periods are diagnosed with eating disorder … Continue reading →
Given that eating disorders disproportionately affect women, it is not unreasonable to assume that men differ from women in clinical presentation, personality and psychological characteristics. My guess would be that they differ. My reasoning is this: males and females grow up facing different pressures and expectations. Given that, I’d think there would be (perhaps only slightly) different risk factors that predispose men and women to develop eating disorders. Thus, I’d think that different groups of men and women (i.e. with different personality characteristics, psychiatric comorbidities, and life experiences) would be susceptible to EDs. (Hopefully that makes sense.) To answer that question, Dr. D. Blake Woodside and colleagues compared men with eating disorders vs. women with eating disorders vs. men without eating disorders.
Why are females much more likely to suffer from eating disorders than males? It appears that (at least) two arguments have been put forth:
One argument has been

Symptom fluctuation and diagnostic crossover are common in eating disorder patients. A study by Eddy et al. (2008) – who followed patients over an average of 7 years – showed that crossover between subtypes and full-syndrome diagnoses is very common : of those initially diagnosed with anorexia nervosa, almost 73% crossed over to another diagnosis (between symptoms and to bulimia nervosa). More specifically, roughly 50% experienced fluctuation between subtypes (restricting, AN-R, and binge/purge type, AN-BP) and roughly 35% crossed over to bulimia nervosa (a subset experienced both). Of those initially diagnosed with bulimia, roughly 14% crossed over to AN-BP and of those, 3.91% crossed over to AN-R.
This finding (though, well-known to ED specialists and even more well-known to patients) has important implications for treatment. For example, CBT and anti-depressants seem to have positive results in bulimic patients, but not so much in anorexics. What then, about those that crossover … Continue reading →
