Eating Disorders: Types, Causes, and Recovery Factors
This paper examines five major eating disorders — anorexia nervosa, bulimia nervosa, binge-eating disorder, night eating syndrome, and eating disorder not otherwise specified (EDNOS) — drawing primarily on Sim et al. (2010). For each disorder, the paper outlines diagnostic criteria, prevalence, subtypes, physical signs, and clinical outcomes. A discussion section synthesizes research on psychological and social causes, including body dissatisfaction, identity development, family dynamics, cognitive distortions, and the relationship between eating disorders and conditions such as depression and obsessive-compulsive disorder. The paper concludes by arguing that full recovery must address physical, behavioral, and psychological dimensions simultaneously.

What makes this paper effective
- The paper systematically covers each disorder in its own section, allowing clear comparison of diagnostic criteria, prevalence rates, and clinical presentations.
- It integrates multiple peer-reviewed sources to move from clinical description into psychological and social causation, giving the paper both a descriptive and analytical dimension.
- The conclusion introduces Bardone-Cone et al.'s three-level recovery framework (physical, behavioral, psychological), providing a meaningful synthesis rather than a simple summary.
Key academic technique demonstrated
The paper demonstrates source-driven organization: each major claim is anchored to a specific citation, and the discussion section deliberately contrasts multiple theoretical perspectives (cognitive, attachment-based, identity-development, and OCD-related) to build a multifactorial explanation of eating disorder etiology. This approach models how to use secondary sources as evidence rather than decoration.
Structure breakdown
The paper opens with a brief introduction defining eating disorders, then devotes a section to each of the five disorder types. A discussion section synthesizes causal research from several additional sources. A short conclusion ties recovery criteria back to the multifactorial nature of these disorders. The structure is encyclopedic in its first half and argumentative in its second, making it useful as both a reference overview and a critical synthesis.
Introduction to Eating Disorders
Eating disorders are psychological illnesses associated with a host of adverse medical conditions, negative psychological effects, and substantial reductions in quality of life. According to Leslie Sim et al. (2010), the main eating disorders are anorexia nervosa, bulimia nervosa, binge-eating disorder, night eating syndrome, and eating disorder not otherwise specified. This paper explores some of the causes research has attributed to these conditions.
Anorexia Nervosa
Anorexia nervosa is described as abnormally low body weight — at least 15% below what would be expected — accompanied by a corresponding fear of weight gain and an undue emphasis on weight and shape in self-evaluation. The incidence of anorexia nervosa is approximately 0.5% to 1% and is highest among adolescent girls and young women.
Anorexia nervosa can be classified into two subtypes: the restricting subtype and the binge-eating/purging subtype. Patients with anorexia nervosa who rarely binge-eat or purge but maintain a fairly regular pattern of caloric restriction may be classified as having the restricting subtype. Those who regularly engage in binge eating and/or compensatory behavior to prevent weight gain may be diagnosed with the binge-eating/purging subtype. Many of those with the restricting subtype will eventually develop binge eating, with at least one-third of patients crossing over into bulimia nervosa. This crossover typically occurs within the first five years of the illness. Women with anorexia nervosa who develop bulimia nervosa are likely to relapse back into anorexia nervosa.
Unfortunately, outcomes for patients diagnosed with anorexia nervosa are poor. There is only a 35% to 85% recovery rate and a protracted recovery period ranging from 57 to 79 months. Furthermore, anorexia nervosa may evolve into a chronic condition and is one of the most medically serious psychiatric disorders. Individuals with this condition are affected not only by the physical consequences of severe weight loss, but also by psychological comorbid conditions that contribute to mortality. Suicides represent a large portion of deaths from anorexia nervosa. Depression, a consequence of poor caloric intake and low weight, is frequently observed with this condition. Anxiety symptoms are also common and often precede the development of the illness.
The negative effect of anorexia nervosa on patients' long-term physical health is well documented. This condition most commonly affects women during the period of peak bone mass development, and the effects on the skeletal system can be severe and debilitating (Sim et al., 2010).
