我们知道更多关于饮食失调：神经性厌食症，神经性贪食症和暴食症。神经性厌食症是追求减肥，远远超出正常范围的显着特征的饮食失调症。这种综合征通常是作为一种恐惧肥胖或追求薄的执行。神经性厌食症的人扭曲的身体形象，往往拒绝进食或以其他极端的方法减肥。暴食症是一个情感为基础的疾病，食品被用来满足内在需要心理上而不是物理上。暴食症让人感到了强大的冲动吃，以满足异常满意饱的感觉。在他们的“好日子”，他们通常没有强制狂欢吃。暴饮暴食症是最近描述的一个。暴食症暴食2例无使用补偿的行为。他们摄入过量的食物远远超过金额正常的人要保持良好的营养。而人们与暴食症没有神经性厌食症;他们也不具有神经性贪食症，因为他们不使用像饥饿，自诱导的呕吐，和泻药的方法来控制体重。

“The field of eating disorders, although still in its infancy, has involved into a sophisticated, multidisciplinary area of research and treatment.” 1But we do understand more about the eating disorders: anorexia nervosa, bulimia nervosa, and binge eating disorder.

Anorexia nervosa is an eating disorder with the remarkable character of pursuing weight loss that far beyond the normal range.1 This syndrome usually performed as a fear of fatness or pursuit of thinness.3 People with anorexia nervosa have distorted body image and often refuse to eat or lose weight by other extreme methods. 2Bulimia nervosa is an emotionally based disorder that foods are used to satisfy the inner need psychologically rather than physically.

The symptom of both disorders also worth to mention. Depression and anxiety disorders are often prominent. Sometime also have liability of mood, impaired concentration, loss of sexual appetite. Other medical complications and health risks include concentration and fatigue loss, skin dryness, abnormal heart function, brittle fingernails and etc. 6

Bulimia nervosa and binge eating disorder share the same symptom of binge eating and limited overlap.5 From the meaning of character, Bulimia means insatiable appetite in Greek that sounds really close to binge eating. Bulimia nervosa can be divided into two types: (1) use of self-induced vomiting, laxatives, or enemas following a binge eating, and (2) use of other inappropri
