Types of Eating Disorders

Anorexia Nervosa 

Symptoms include: 

  • Over evaluation of shape and weight and control 
  • Judging self-worth largely and even exclusively in terms of shape and weight and the ability to control 
  • Active maintenance of low body weight – less than 85% of that expected or a body mass index of 17.5 or below 
  • Inadequate food intake 
  • Fear of weight gain 
  • Obsession over weight and food 
  • Inability to understand the severity of the situation 

Bulimia Nervosa 

Symptoms include: 

  • Over evaluation of shape and weight 
  • Recurrent binge eating and a sense of loss of control at the time 
  • Extreme weight control behaviour – sustained dietary restriction, recurrent  self-induced vomiting or laxative misuse 
  • Feeling out of control during binge eating episodes 
  • Self-esteem and self-worth related to body image 

Binge Eating Disorder (BED) 

Symptoms include: 

  • Episodes of eating large amounts of food without behaviours of attempting to prevent weight gain such as vomiting or taking laxatives 
  • Feeling out of control during binge eating episodes 
  • Feeling shame or guilt because of the binge eating 
  • Eating when not hungry, eating alone due to being embarrassed about the behaviour or eating to the point of being uncomfortable and overly full 

Emotional Overeating 

Symptoms include: 

  • Eating large amounts of food in response to negative emotions 
  • Used as a coping mechanism for dealing with emotions 
  • Low self-esteem and negative body image 

Other Eating Disorders  

There are many types of disordered eating that don’t quite fit into neat categories but can cause significant distress or impairment. 

Other Specified Feeding and Eating Disorders (OSFED) diagnoses include: 

  • Atypical anorexia nervosa (weight is not below normal) 
  • Bulimia nervosa (with less frequent behaviours) 
  • Binge-eating disorder (with less frequent occurrences) 
  • Purging disorder (purging without binge eating) 
  • Night eating syndrome (excessive nighttime food consumption) 

Unspecified Feeding or Eating Disorders (UFED)/Eating Disorders Not Otherwise Specified (EDNOS) 

This is a catch-all category that will be recognised by varying forms of behaviour and thinking patterns around eating, which can cause significant problems in day to day life and tend to be entered around self-worth based on shape and weight.
