PSYC 318 Lecture Notes - Lecture 10: Bulimia Nervosa, Anorexia Nervosa, Bariatric Surgery
Document Summary
The prevalence of eating disorders has increased rapidly over the last half century. As a result, they were included for the first time as a separate group of disorders in dsm-iv. In bulimia nervosa, dieting results in out-of-control binge-eating episodes that are often followed by purging the food through vomiting or other means. In binge-eating disorder, a pattern of binge eating is not followed by purging. Anorexia nervosa, in which food intake is cut dramatically, results in substantial weight loss and sometimes dangerously low body weight. Bulimia nervosa and anorexia nervosa are largely confined to young women in developed countries who are pursuing a thin body shape that is culturally mandated and biologically inappropriate, making it extremely difficult to achieve. Without treatment, eating disorders become chronic and can, on occasion, result in death. Several psychosocial treatments are effective, including cognitive-behavioral approaches combined with family therapy and interpersonal psychotherapy. Drug treatments are less effective at the current time.
