Anorexia nervosa is recognized as a severe eating disorder characterized by a distorted body image, obsession with food and weight, and unwarranted fear of gaining weight. People with this disorder tend to restrict their caloric intake and use various measures to prevent weight gain and promote weight loss. As a result, individuals with this eating disorder tend to be very slim. However, another type of anorexia known as atypical anorexia nervosa isn’t as recognizable.
Eating disorders aren’t always as black and white as their diagnoses make them seem. Diagnostic criteria consider the most common symptom combinations of these disorders, but many struggling with them don’t display as clear-cut of a list. For this reason, the Diagnostic and Statistical Manual of Mental Health Disorders (DSM) created the OSFED (Other Specified Feeding and Eating Disorder) category of diagnoses for eating disorders.
The OSFED category specifies eating disorders that “cause clinically significant distress or impairment in social, occupational, or other important areas of functioning predominate but do not meet full criteria for any of the disorders in the feeding and eating disorders diagnostic class.”1 Atypical anorexia nervosa is one of these disorders.
Atypical anorexia nervosa is an eating disorder in which a person meets all the criteria for anorexia nervosa except that despite significant weight loss, the person is within their normal or recommended weight range, which is also referred to as weight suppression.1 Atypical anorexia is more common than we think, comprising nearly one-third of hospital inpatient eating disorder treatment programs.2
While more research needs to be conducted to understand atypical anorexia as much as anorexia nervosa, below are some known causes of the disorder to be mindful of.
An atypical anorexia nervosa diagnosis is different from typical anorexia. Even though they’re different, they share several characteristics, such as extreme emphasis placed on body shape and appearance, fear of weight gain, and restricted caloric/energy intake.
However, the major difference between typical and atypical anorexia is that people with atypical anorexia are not severely underweight and don’t have to experience significant weight loss to be diagnosed. Because someone with atypical anorexia may be at a normal weight or even overweight, the eating disorder may not be as obvious.
However, there are still many behaviors and signs associated with the disorder. Common signs and symptoms of atypical anorexia nervosa include:
People with atypical anorexia nervosa may deem themselves as “not sick enough” or use their weight to “prove” that they’re “healthy” or “fine.” If an individual is not severely underweight, it’s easy for their disorder to slip through the cracks. For this reason, keep these signs and symptoms in mind if you suspect that a loved one may have this disorder and needs eating disorder support.
