神経性無食欲症
Eating disorders are psychological conditions characterized by abnormal and hazardous eating habits. There exist several types, the most common being anorexia nervosa, bulimia nervosa, and binge-eating disorder. Anorexia nervosa occurs when individuals consider themselves as overweight despite being concerningly underweight. Individuals will monitor their weight by restricting consumption of calories and certain foods, and develop an obsession with their body image. Bulimia nervosa is characterized by reoccurring binge-eating episodes following by radical compensatory behaviours including fasting, self-induced vomiting, abuse of laxatives and diuretics, and/or excessive physical exercise. Similar to bulimia nervosa, individuals with binge-eating disorder will consume large portions of food in a short amount of time, but will not engage in compensatory behaviours.
