Atypical anorexia nervosa, also known as atypical anorexia or Eating Disorder Not Otherwise Specified (EDNOS), is a subtype of anorexia nervosa. It is characterized by the same features and behaviors as typical anorexia nervosa, but with one key difference: individuals with atypical anorexia do not meet the low weight criteria typically associated with a diagnosis of anorexia nervosa.
In traditional anorexia nervosa, one of the diagnostic criteria is that individuals have a body weight significantly below what is considered normal or expected for their age, height, and sex. However, in atypical anorexia, despite having severe restrictions on food intake and exhibiting other behaviors commonly seen in anorexia nervosa, the individual's weight remains within or above the normal range.
The key features of atypical anorexia include:
Severely restricted food intake: People with atypical anorexia engage in intense dietary restriction, often significantly reducing their caloric intake.
Fear of weight gain: Like in typical anorexia nervosa, individuals with atypical anorexia have an intense fear of gaining weight or becoming "fat."
Distorted body image: They may have a distorted perception of their body and may see themselves as overweight or larger than they are.
Physical and psychological consequences: Atypical anorexia can lead to significant physical and psychological consequences, just like traditional anorexia nervosa.
The primary difference between typical anorexia nervosa and atypical anorexia is the individual's weight status. In typical anorexia, the person's weight falls below the expected range, whereas in atypical anorexia, their weight may be within the normal range or even higher. However, the psychological and physical impact of atypical anorexia can still be severe and may require similar treatment approaches to address the underlying issues and promote recovery.
It's important to note that the distinction between different eating disorder subtypes can be challenging, and the severity and presentation of symptoms can vary among individuals. As with any eating disorder, early recognition, and intervention are essential for promoting successful recovery. If you or someone you know is struggling with disordered eating or an eating disorder, seeking help from a healthcare professional or an eating disorder specialist is crucial for proper evaluation, diagnosis, and treatment.
