Anorexia Nervosa

神经性厌食症

Definition

说明

Anorexia nervosa is an eating disorder characterized by refusal to maintain body weight that is within the minimal range of normal. The affected individual has a distorted body image, perceiving self as globally overweight or obsessing about shape and size of particular body parts.

神经性厌食症属于进食障碍病,特点是拒绝体胖,尽管它已经是最低限度的正常体重。患者对体形看法偏执,认为自己总体超重或沉迷于身体特定部位的形状和尺寸。

There are two subtypes of anorexia nervosa. One is the restricting type, wherein the individual severely restricts food intake and compulsively exercises. The other is the binge eating and purging type marked by restricted dietary intake coupled with intermittent episodes of binge eating, followed by purging through self-induced vomiting or use of ipecac, laxatives, diuretics, or enemas.

神经性厌食症分两种。一是限制型的,患者严格限制食物摄入并强迫自己运动。另一种是狂饮狂泻型的,其特点是在限制饮食的同时又伴有间歇性暴饮,接着又通过自我诱导式呕吐或使用吐根、缓泻剂、利尿剂和灌肠剂等催泻。

Pathophysiology

病理生理学

A variety of psychologic factors are associated with the development of behaviors characteristic of anorexia nervosa. Low self-esteem often plays a significant role. Weight loss is viewed as an achievement, and self-esteem becomes dependent on body size and weight. There is also a relationship between eating disorders and mood disorders. In some cases, major depression may result from nutritional deprivation. Individuals with anorexia nervosa may lack spontaneity in social situations and may be emotionally restrained. The excess use of appetite suppressants or diet pills is seen in both types.

很 多病因素都与一些神经性厌食症特有的行为有关。缺乏自尊常常起着很重要的作用。减肥使其产生一种成就感,自尊依赖于体形和体重。饮食障碍与心境障碍也有关 系。有些病人严重抑郁,这通常是营养不足引起的,厌食症患者在社交场合缺乏自发性,在情感上会很拘束。这两类厌食症都会发生过度使用食欲抑制剂或节食丸这 种情况。

Family dynamics may play a role in development of symptoms. Parents may be controlling and overly protective. Eating behaviors may emerge in an unconscious attempt to gain control over the environment. Also contributing to this eating disorder is a societal ideal slimness that the adolescent strives to emulate. In some cases, diminished weight and loss of secondary sexual characteristics may be related to difficulty in accepting maturation into adulthood.

家族情况对症状出现也有一定影响。父母对小孩控制过严,保护过度。有意无意地想要控制环境,从而形成了不良饮食习惯。造成饮食障碍的另一个因素是社会对所谓的理想的苗条的追求,青少年努力想要效法这种苗条。在有些病例中,体重减轻,失去第二性征可能也与难以接受成年有关。

Therapeutic Management

治疗

Treatment is provided on an outpatient basis unless severe medical problems emerge. An interdisciplinary approach is needed to ensure optimal outcomes. Outpatient treatment includes medical monitoring, dietary planning to restore nutritional state, and long-term psychotherapy to work through underlying issues. Psychopharmacologic treatment may be initiated to treat symptoms of depression, anxiety, and obsessive-compulsive behaviors. Hospitalization is indicated if the adolescent weighs less than 20% of ideal body weight or is unable to adhere to the treatment program on an outpatient basis, or when neurologic deficits, hypokalemia, and cardiac arrhythmias exist.

如无急诊情况出现,一般行门诊治疗。为确保理想治疗效果,通常进行多科室诊治。门诊治疗包括医学监测、饮食计划以恢复营养、长期进行心理疗法解决潜在问题。抑郁症、焦虑症和强迫性行为可心通过精神药理手段进行治疗。如体重低于理想体重20%或门诊治疗无法保证治疗计划落实,或出现神经缺欠、低钾血及心律失常,这时就需要住院。

The following medications may be used:

Antidepressants--the selective serotonin reuptake inhibitors (SSRI) are also used, particularly if compulsive exercising is a component of the illness (imipramine, desipramine, fluoxetine, sertraline, paroxetine)
