Avoidant/Restrictive Food Intake Disorder
Avoidant/restrictive food intake disorder is a disorder in which eating is avoided to an extent where nutritional requirements are not met and an extensive amount of weight and energy is lost. This disorder is most commonly seen in children.
Anorexia nervosa is characterized by persistent food restriction, an intense fear of gaining weight and becoming fat or persistent behavior that interferes with weight gain, and a distorted body image. Individuals with anorexia nervosa maintain a body weight that is below a minimally normal level for age, sex, developmental course and physical health.
Bulimia nervosa is characterized by frequent episodes of binge eating followed by compensatory behaviors to prevent weight gain such as self-induced vomiting. This diagnosis is given to those who exhibit binge eating and compensatory behaviors at least once per week for three months.
Binge eating disorder is defined as recurring episodes of eating significantly more food in a short period of time than most people would eat under similar circumstances. These episodes are marked by feelings of lack of control. People with binge eating disorder may feel guilty, embarrassed, or disgusted and may binge eat alone to hide the behavior. This diagnosis is given to those who have these episodes at least once a week for three months.
This category encompasses any eating disorder that does not meet the full criteria for any of the other eating disorders.
