摘要:“饮食失调的领域,虽然还处于起步阶段,发展成为研究和治疗的一个复杂的,多学科的领域。”
ate compensatory behaviors such as excess exercise to avoid weight gain. Binge eating disorder is exactly same as the binge eating part of bulimia nervosa. People with bulimia nervosa usually feel a strong wish to eat and this urge is driven by the belief that the satisfaction could only be achieved by giving into a craving food that is much more intense feelings of hunger. Nowadays many therapists refer to binge eating disorder as compulsive overeating. This disorder usually divides into two common patterns: compulsively snacking over long intervals and consumption of large amount food at one time. Both beyond the requirements to satisfy normal hunger significantly.7However, binge eating disorder occurs against the background of a general tendency to overeat while bulimia nervosa usually go with the dietary restraint.
Why do eating disorders occur? All three eating disorders anorexia, bulimia nervosa and binge eating have some explanations though none has been proved conclusively. First is the adolescent development explanation. Some adolescents who diet may become so concerned about weight control that their eating behavior escaped from normal and they develop anorexia nervosa. Those who respond to diet by experiencing out of control part may develop bulimia nervosa or binge eating disorder. 8Another is physiological explanation. One hypo
thesis suggests that an increase in opioid activity occurs in brain that makes people happy when potential anorexia nervosa patients eat inadequate amounts of foods.

Phelps and colleges found that concern about body weight increased sharply when girls reached puberty, as did eating disordered behaviors such as self-induced vomiting. 11
Psychological treatments are more effective than drug treatment for all three eating disorders: anorexia nervosa, bulimia nervosa and binge eating disorder. There is moderate evidence proved that family based therapy for adolescents has moderate beneficial effect on anorexia nervosa.This involves the family preparing the food and supervising meals and snacks the child must eat. This treatment really works but it could be difficult if both parents are working or the patient become older. By this stage, patients usually are able to return to school or work. Strong evidence proved that cognitive behaviour therapy has moderate beneficial effect on bulimia nervosa since most patients have low self-esteem and moderate evidence proved this therapy has moderate beneficial effect on binge eating disorder.
