Two-thirds of people with an eating disorder diagnosis will suffer from anxiety in their lifetime . That means two-thirds of people will have to fight for recovery from their anxiety and eating disorders.
Talk about overwhelming odds.
This comorbidity can alter how the individual develops, experiences, is treated for and recovers from their eating disorder.
Comorbidity of Anxiety and Eating Disorders
We can’t discuss the co-occurrence of anxiety and eating disorders without having the “chicken-or-the-egg” conversation – which causes which? As with the “chicken-or-the-egg” conversation, there is no clear answer.
However, research indicates that the onset of an anxiety disorder often precedes that of an eating disorder, so make of that what you will .
Researchers are often one of the 3 camps related to why these disorders commonly co-occur – 1) anxiety is a risk factor for eating disorder development, 2) anxiety is secondary to eating pathology, and 3) both disorders share common vulnerability factors .
Regardless of which of these you believe, there is no denying that the two seem to be related, with individuals with bulimia nervosa showing a lifetime prevalence rate of anxiety disorders of 25-75% and individuals with anorexia nervosa showing a lifetime prevalence rate of anxiety disorders of 23-75% .
The existence of an anxiety disorder in eating disorder treatment can mean changes in how the eating disorder psychopathology and behaviors are treated.
As such, it is important to make your treatment team aware of any previous anxiety disorder diagnoses as well as be honest and open about the symptoms you experience.
Research shows that recovery outcomes are improved if both disorders are treated simultaneously as opposed to attempting to treat one then the other.
In treatment, there is a likelihood that the topic of taking anti-anxiety medications to mitigate some of these symptoms will come up. The process of taking medication is purely based on your willingness, however, so don’t hesitate to voice your thoughts and opinions in this process.
The presence of a co-occurring anxiety disorder is a challenge in eating disorder treatment. However, it is not unsurmountable. In fact, processing and treating both at once may provide valuable insights into how the two disorders are interrelated for you, which can be valuable information to have for recovery.
Above all, know that it is absolutely possible to live a life free of the shackles of an anxiety disorder and an eating disorder.
