An atypical eating disorder isn’t something that many people are familiar with or have even heard of. Typically, an eating disorder is described as atypical if it has features that closely resemble anorexia or bulimia but does not meet the precise diagnostic criteria of either one.
Many eating problems do not fit into the more common diagnostic boxes but it doesn’t mean that they’re any less serious or dangerous. A few examples of why an eating disorder may be atypical include:
* The person’s weight may be just above the diagnostic threshold for anorexia
* Binge eating and purging may occur but not often enough to be classed as a ‘problem’
* In women, if boss mass index (BMI) is less that 17.5 but menstruation still takes place
Atypical anorexia nervosa fulfils some of the features of anorexia but the patient’s overall clinical picture does not justify being diagnosed as anorexic. For example, the patient could have a fear of becoming fat and may no longer be menstruating due to their low weight but there might not have been any drastic weight loss that took place.
Atypical bulimia follows a similar pattern because there may be recurrent bouts of overeating and purging or overuse of laxatives, but the patient may not witness a significant weight change or the typical concern about body shape and weight.
Due to the inexact symptoms of an atypical eating disorder, it can be very difficult to recognise and diagnose. However, some key symptoms may include:
* Going through periods of being severely underweight followed by periods of being severely overweight
* Eating habits have undergone changes that are uncharacteristic of the person
* The person is no longer engaging in social activities they used to. They may also be avoiding friends and family so that the problem isn’t identified
