Other Specified Feeding or Eating Disorders

The eating disorders in this category are related to anorexia nervosa, bulimia nervosa, and binge-eating disorder but differ in that not all of the same conditions apply.

Examples include:

  • Anorexia nervosa type: all of the same characteristics as anorexia nervosa, however, there is the appearance of being at a normal weight because significant weight loss started at a higher than average weight. 
  • Binge-eating disorder type: all of the same characteristics as for binge-eating disorder; however the binge-eating episodes occur less frequently than once per week and/or for fewer than three months.
  • Bulimia nervosa type: all of the same characteristics as for bulimia nervosa, however the cycle of bingeing and purging occurs less frequently than once per week and/or for fewer than three months.
  • Night eating syndrome: The excessive consumption of food following an evening meal or after waking from sleep in the night, which causes extreme psychological distress and interferes with daily functioning.
  • Purging disorder: Persistent purging behaviours without the presence of binge-eating episodes.

Avoidant and Restrictive Food Intake Disorder

Avoidant/restrictive food intake disorder (ARFID) involves limitations in the amount and/or types of food consumed, but unlike anorexia, ARFID does not involve any distress about body shape or size, or fears of fatness. 

ARFID is a mental illness which can severely compromise growth, development, and health.
