Anxiety-Induced Anorexia

Anxiety is a common mental health condition that affects millions of people worldwide. It can manifest in various forms, such as generalized anxiety disorder (GAD) and obsessive-compulsive disorder (OCD), and it can significantly impact an individual’s daily life. In recent years, researchers have begun to uncover a complex relationship between anxiety and eating disorders, particularly anorexia nervosa.

In this blog post, we will delve into anxiety-induced anorexia, exploring the connection between anxiety disorders and eating disorders, including bulimia nervosa, binge eating disorder, and the symptoms of anxiety that can affect eating behaviors. 

We will also examine the role of GAD and OCD in the development and maintenance of anorexia and discuss how understanding this connection can aid in the diagnosis and treatment of individuals struggling with these co-occurring disorders. Moreover, we’ll examine the intersection of social anxiety and eating disorders.

Anxiety-Induced Anorexia

Anorexia nervosa is a serious eating disorder characterized by restrictive eating, an intense fear of gaining weight, and a distorted body image. While the exact cause of anorexia is not fully understood, research suggests that a combination of genetic, environmental, and psychological factors contribute to its development. One such psychological factor that has gained increasing attention in recent years is anxiety.

Anxiety disorders are a group of mental health conditions that involve excessive worry, fear, and nervousness. They can manifest in different forms, such as GAD and OCD, and can significantly impact an individual’s thoughts, emotions, and behaviors. 

When anxiety becomes overwhelming, it can trigger a range of coping mechanisms, including maladaptive eating behaviors, which can lead to the development of anorexia in vulnerable individuals. This phenomenon is often referred to as anxiety-induced anorexia.

The Connection Between GAD and OCD in Anorexia

GAD and OCD are two common anxiety disorders that have been implicated in the development and maintenance of anorexia. 

GAD is characterized by persistent and excessive worry about a wide range of everyday concerns. In contrast, OCD is characterized by intrusive and repetitive thoughts (obsessions) and repetitive behaviors (compulsions) aimed at reducing anxiety. Both GAD and OCD can significantly impact an individual’s eating behaviors and contribute to the development of anorexia.

Research has shown that individuals with GAD may use restrictive eating as a way to cope with their excessive worry and anxiety. The rigid rules and routines around food intake may provide a sense of control and order amid overwhelming anxiety. Similarly, individuals with OCD may use compulsive behaviors related to food, such as obsessive calorie counting or ritualistic eating patterns, to alleviate their anxiety and reduce their obsessions.

Over time, these maladaptive eating behaviors can lead to the development of anorexia, as the individual becomes increasingly preoccupied with food and weight loss as a means of coping with their anxiety. One can find additional insights into this process on the American Psychological Association’s website.

GAD and OCD have been found to play a significant role in developing and maintaining anorexia. The relationship between these anxiety disorders and anorexia can be complex and intertwined. Research has shown that individuals with anorexia often experience high levels of anxiety, particularly related to body image concerns, fear of gaining weight, and perfectionism. This correlation has been documented extensively on the National Institute of Mental Health’s website.

GAD, characterized by excessive worry, can contribute to the development of anorexia through its impact on cognitive distortions related to food and body image. Individuals with GAD may excessively worry about their body weight, shape, and appearance, leading to a heightened fear of gaining weight and an increased drive for thinness.

The constant worry and anxiety about food and body image can reinforce the individual’s restrictive eating behaviors and drive for weight loss to alleviate their anxiety.

Similarly, OCD, characterized by intrusive thoughts and repetitive behaviors, can also contribute to the development of anorexia in individuals with comorbid OCD and an eating disorder. Obsessions related to food, weight, and body image, such as fear of contamination from food or the need for perfectionism in eating patterns, can drive individuals to engage in restrictive eating behaviors and compulsive rituals, such as excessive exercise or strict food rules.

These behaviors are often aimed at reducing the anxiety and distress caused by the obsessions but can further reinforce the disordered eating patterns and perpetuate the cycle of anorexia.

Eating and Feeding Disorders: Bulimia Nervosa, Binge Eating Disorder

Eating and feeding disorders are a group of mental health conditions that involve abnormal eating behaviors and attitudes toward food and body weight. These disorders often co-occur with anxiety disorders, and the relationship between the two can be complex and bidirectional.

Bulimia nervosa is an eating disorder characterized by episodes of binge eating followed by compensatory behaviors, such as self-induced vomiting or excessive exercise, to prevent weight gain. Research has shown that individuals with bulimia often experience high levels of anxiety, particularly related to body image concerns and fear of gaining weight. The binge eating episodes may serve as a way to temporarily alleviate their anxiety and escape from distressing thoughts and emotions.

However, the compensatory behaviors used to counteract binge eating can further perpetuate the cycle of anxiety and maladaptive eating behaviors, ultimately contributing to the development of anorexia.

Binge eating disorder, on the other hand, is characterized by recurrent episodes of binge eating without compensatory behaviors. Research has shown that individuals with binge eating disorders may use food as a coping mechanism to manage their anxiety and emotions. 

Binge-eating episodes may provide a temporary escape from distressing thoughts and emotions. Still, they can also lead to feelings of guilt, shame, and further anxiety, which can exacerbate the cycle of disordered eating behaviors.

Anxiety can also affect eating behaviors in individuals with other feeding and eating disorders, such as avoidant/restrictive food intake disorder (ARFID) and pica. 

ARFID is characterized by a persistent lack of interest in or avoidance of food, which can be driven by sensory sensitivities, fear of choking, or other aversive experiences related to food. Anxiety, particularly associated with sensory sensitivities or fears around food, can significantly impact an individual’s willingness and ability to eat, leading to further malnutrition and disordered eating behaviors.

Pica is characterized by the persistent eating of non-food substances, such as hair, dirt, or paper. Anxiety and stress can trigger episodes of pica as a way to cope with distressing emotions, leading to further detrimental effects on an individual’s physical health and eating behaviors.

Anxiety Affect Eating Disorders Symptoms

Anxiety can also affect the symptoms and course of eating disorders.

For example, anxiety can exacerbate body image concerns, which are often central to developing and maintaining anorexia.

Individuals with anorexia may have a distorted body image, perceive themselves as larger than they actually are, and experience intense fear and anxiety about gaining weight. Anxiety can amplify these distorted body image beliefs, leading to increased rigidity and severity of dietary restrictions, excessive exercise, and other maladaptive eating behaviors aimed at maintaining low body weight.

Moreover, anxiety can affect the severity and frequency of binge eating episodes in individuals with bulimia and binge eating disorder. High levels of anxiety can trigger episodes of binge eating as a maladaptive coping mechanism, providing temporary relief from distressing emotions. Anxiety can also lead to increased feelings of guilt, shame, and self-criticism after binge eating episodes, which can further perpetuate the cycle of disordered eating behaviors.

Furthermore, the combination of GAD and OCD in individuals with anorexia can significantly impact their overall functioning and quality of life. The constant worry and anxiety from GAD, along with the intrusive thoughts and compulsive behaviors from OCD, can lead to a high level of distress and impairment in daily functioning. This can further exacerbate the severity and chronicity of anorexia, making it more challenging to achieve and maintain recovery.

It is important to note that the relationship between anxiety disorders, such as GAD and OCD, and anorexia is complex and multifactorial. The interplay between genetics, neurobiology, personality factors, environmental influences, and other psychological factors can contribute to developing and maintaining anxiety-induced anorexia. Therefore, a comprehensive and holistic approach to assessment and treatment is essential in addressing the complex nature of anxiety-induced anorexia.


In conclusion, anxiety-induced anorexia is a complex and multifaceted condition that involves the interplay between anxiety disorders, such as GAD and OCD, and disordered eating behaviors. The connection between anxiety and eating disorders is significant, and individuals with comorbid anxiety disorders and anorexia may experience more severe symptoms and impairment in daily functioning. 

Early identification and intervention are crucial in addressing anxiety-induced anorexia, and a comprehensive treatment approach that addresses both the underlying anxiety disorders and the disordered eating behaviors is essential.

Treatment approaches for anxiety-induced anorexia may include: 

  • Cognitive behavioral therapy (CBT)
  • Medication
  • Nutritional rehabilitation
  • Family-based treatment (FBT)
  • Supportive psychotherapy
  • Group therapy
  • Body image and self-esteem interventions, and
  • Relapse prevention strategies

A collaborative and holistic approach that involves a qualified treatment team, including mental health professionals, registered dietitians, and other healthcare providers, can provide the best outcomes for individuals with anxiety-induced anorexia.

If you or someone you know is struggling with anxiety-induced anorexia or any other eating disorder, it is important to seek professional help from qualified healthcare providers.
