臨床英語英漢對照學習:神經(jīng)性厭食癥

Anorexia Nervosa

神經(jīng)性厭食癥

Definition

說明

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.

神經(jīng)性厭食癥屬于進食障礙病，特點是拒絕體胖，盡管它已經(jīng)是最低限度的正常體重�；颊邔�體形看法偏執(zhí)，認為自己總體超重或沉迷于身體特定部位的形狀和尺寸。

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.

神經(jīng)性厭食癥分兩種。一是限制型的，患者嚴格限制食物攝入并強迫自己運動。另一種是狂飲狂瀉型的，其特點是在限制飲食的同時又伴有間歇性暴飲，接著又通過自我誘導式嘔吐或使用吐根、緩瀉劑、利尿劑和灌腸劑等催瀉。

Pathophysiology

病理生理學

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 多病因素都與一些神經(jīng)性厭食癥特有的行為有關。缺乏自尊常常起著很重要的作用。減肥使其產(chǎn)生一種成就感，自尊依賴于體形和體重。飲食障礙與心境障礙也有關 系。有些病人嚴重抑郁，這通常是營養(yǎng)不足引起的，厭食癥患者在社交場合缺乏自發(fā)性，在情感上會很拘束。這兩類厭食癥都會發(fā)生過度使用食欲抑制劑或節(jié)食丸這 種情況。

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.

家族情況對癥狀出現(xiàn)也有一定影響。父母對小孩控制過嚴，保護過度。有意無意地想要控制環(huán)境，從而形成了不良飲食習慣。造成飲食障礙的另一個因素是社會對所謂的理想的苗條的追求，青少年努力想要效法這種苗條。在有些病例中，體重減輕，失去第二性征可能也與難以接受成年有關。

Therapeutic Management

治療

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.

如無急診情況出現(xiàn)，一般行門診治療。為確保理想治療效果，通常進行多科室診治。門診治療包括醫(yī)學監(jiān)測、飲食計劃以恢復營養(yǎng)、長期進行心理療法解決潛在問題。抑郁癥、焦慮癥和強迫性行為可心通過精神藥理手段進行治療。如體重低于理想體重20%或門診治療無法保證治療計劃落實，或出現(xiàn)神經(jīng)缺欠、低鉀血及心律失常，這時就需要住院。

The following medications may be used:

使用藥物：

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)

抗抑郁藥，也可使用選擇性5羥色胺再吸收抑制劑，特別是患有強迫運動時，如丙米嗪、地昔帕明、氟西汀、舍曲林、帕羅西丁等。
