The following eating disorders are lesser-discussed. However, this does not detract from the dangers nor the seriousness they may present to individuals. 

Bigorexia (Muscle Dysmorphia)

Considered to be anorexia in reverse. Those affected by Bigorexia develop an unhealthy obsession with image.

There is an accompanying profound fear of losing weight and hence muscle.

Eating practices are very extreme. Sufferers restrict themselves to a high protein diet, supplemented by high protein shakes, eating behaviour which can become quite socially isolating.   

Bigorexia where big isn't big enough!


This eating disorder materialises in people that have Type1 Diabetes due to the deliberate (and dangerous) omission of sufficient insulin.

Orthorexia Nervosa

This relatively new eating disorder is creating much debate among academics and professionals as to whether it is a sub-type of anorexia nervosa or a type characterised by its own features.  

Characterised by the obsession with healthy eating. The obsession on healthy eating may begin with th restricting of certain foods for either one or a combination of reasons, i.e. medical, general health or ethical. Gradually the restrictive practice progresses into dietary purity. 

Such restrictive diets can create situations of social isolation - obsession with such radical pure foods will prevent social eating; preoccupation with preparation of the pure foods will prevent the individual from spending time with family and friends - in many cases eating separately from them.

Whilst the preference for pure foods can be beneficial there is a strong possibility that the obsession can cause malnutrition, which in some cases can be fatal.  


Feeding and Eating Conditions Not Elsewhre Classified (formerly Eating Disorder Not Otherwise Specified (EDNOS) 

This category of eating disorder is so called because its characteristics fall short of the criteria for anorexia, bulimia and binge-eating disorder. Many people failed to access proper treatment due to its categorisation.

The new DSM has opted to rename this eating disorder 'Feeding and Eating Conditions Not Elsewhere Classified'. Furthermore, criteria for the other main eating disorders has been amended which should, in theory, mean that fewer people fall into this category.
