Introduction to Eating Disorders
Introduction
Eating disorders involve a persistent disturbance of eating or of behavior related to eating that Alters consumption or absorption of food Significantly impairs physical health and/or psychosocial functioning Specific eating disorders include Anorexia Nervosa None Avoidant/Restrictive Food Intake Disorder (ARFID) None Binge Eating Disorder None Bulimia Nervosa None Pica None Rumination Disorder None Anorexia nervosais characterized by a relentless pursuit of thinness, a morbid fear of obesity, a distorted body image, and restriction of intake relative to requirements, leading to a significantly low body weight to the point where health is harmed. This disorder may or may not include purging (eg, self-induced vomiting). Avoidant/restrictive food intake disorderis characterized by avoidance of food or restriction of food intake that results in significant weight loss, nutritional deficiency, dependence on nutritional support, and/or marked disturbance of psychosocial functioning. But unlike anorexia nervosa and bulimia nervosa, this disorder does not include concern about body shape or weight. Binge eating disorderis characterized by recurrent episodes in which people consume large amounts of food and feel as if they have lost control. Episodes are not followed by inappropriate compensatory behavior (eg, self-induced vomiting). Bulimia nervosais characterized by recurrent episodes of binge eating followed by some form of inappropriate compensatory behavior such as purging (self-induced vomiting, laxative or diuretic abuse), fasting, or driven exercise. Picais persistent eating of nonnutritive, nonfood material that is not developmentally appropriate (ie, pica is not diagnosed in children<2 years) and not part of a cultural tradition. Rumination disorderis repeated regurgitation of food after eating. Eating disorders are more common among women, especially younger women, than among men.
