Eating Disorders and Co-occurring Mental Health Conditions

Eating Disorders and Co-occurring Mental Health Conditions

Eating disorders are serious mental health conditions characterised by abnormal or disturbed eating habits and preoccupations with food, body weight, and shape. Common types of eating disorders include anorexia nervosa, bulimia nervosa, and binge-eating disorder.

Co-occurring mental health conditions, also known as comorbid conditions, refer to the presence of one or more additional mental health disorders occurring alongside a primary condition. In the context of eating disorders, common co-occurring conditions include depression, anxiety disorders, obsessive-compulsive disorder (OCD), post-traumatic stress disorder (PTSD), and substance abuse disorders. In this article, we will discuss the link between eating disorders and co-occurring mental health conditions.

It is important to be aware of possible co-occurring conditions for effective eating disorder treatment of any eating disorder, for several reasons.


Co-occurring conditions can significantly influence the presentation and severity of eating disorders. For example, individuals with co-occurring depression may exhibit more severe symptoms of an eating disorder, such as increased episodes of binge eating or purging.

Recognising and addressing these overlapping symptoms is crucial for a comprehensive understanding of the patient’s mental health status.

Addressing co-occurring conditions can lead to better treatment outcomes. Integrated treatment plans that simultaneously address both the eating disorder and the co-occurring mental health conditions are more likely to result in sustained recovery.

Co-occurring mental health conditions often exacerbate the stress and emotional challenges faced by individuals with eating disorders.

Such a holistic approach can reduce the reliance on maladaptive eating behaviours as a means of coping with underlying psychological distress. Treating both conditions concurrently helps mitigate these risks and promotes overall health and well-being.


Common Co-occurring Conditions

Integrated treatment approaches that consider the interplay between eating disorders and other mental health conditions can lead to more comprehensive and successful recovery outcomes. By understanding and addressing these co-occurring conditions, healthcare providers can offer more targeted and effective interventions to support individuals.

Common co-occurring mental health conditions that can exist in a person with eating disorders include, but may not be limited, to the following:

Anxiety Disorders

Anxiety disorders, including generalised anxiety disorder (GAD), social anxiety disorder, and panic disorder, frequently co-occur with eating disorders. The constant worry and fear associated with anxiety can exacerbate eating disorder behaviours, such as restrictive eating or binging.

Anxiety can contribute to the development of eating disorders as individuals may use disordered eating behaviours as a coping mechanism to manage their anxiety.

Depression

Depression is commonly seen in individuals with eating disorders. Symptoms of depression, such as low mood, lack of energy, and feelings of hopelessness, can both contribute to and result from eating disorders.

Depressive symptoms can lead to disordered eating as a form of self-soothing or control. Alternatively, the physical and emotional toll of an eating disorder can lead to the development of depressive symptoms.

Obsessive-Compulsive Disorder (OCD)

OCD is characterised by intrusive thoughts and repetitive behaviours. Individuals with eating disorders may exhibit obsessive thoughts about food, weight, and body image, as well as compulsive behaviours like excessive exercise or rigid eating routines.

The compulsive nature of OCD can intensify disordered eating patterns, while the rituals associated with eating disorders can mirror OCD behaviours, creating a cycle that is difficult to break.

Post-Traumatic Stress Disorder (PTSD)

PTSD can develop after experiencing a traumatic event. Individuals with eating disorders often have a history of trauma, and PTSD symptoms can exacerbate disordered eating as a way to cope with trauma-related distress.

Trauma can trigger eating disorder behaviours as a method of regaining control or numbing emotional pain. The stress of an eating disorder can also retraumatise individuals and worsen PTSD symptoms.

Substance Abuse Disorders:

Substance abuse and eating disorders frequently co-occur. Individuals may use substances to control appetite, manage weight, or cope with emotional pain related to their eating disorder.

Substance abuse can lead to the development of eating disorders and vice versa. The dual presence of both disorders can complicate treatment and recovery, requiring integrated intervention strategies.


Impact of Co-occurring Conditions on Treatment and Recovery

Symptoms of these co-occurring conditions often overlap with or exacerbate the symptoms of eating disorders. For instance, anxiety can heighten preoccupation with food and body image, while depression can reduce motivation for recovery. Also, individuals with multiple mental health conditions may exhibit resistance to treatment, either because they have previously received ineffective treatment or because they struggle to trust healthcare providers due to past trauma.

However, treating just the eating disorder without addressing the co-occurring conditions often leads to incomplete recovery. The presence of co-occurring conditions can also increase the likelihood of relapse if all underlying issues are not adequately addressed.

Addressing both eating disorders and co-occurring mental health conditions requires integrated and comprehensive treatment approaches. Integrated therapy combines treatments for both conditions within the same therapeutic framework, such as using Cognitive Behavioural Therapy (CBT) adapted for both anxiety and eating disorders, or Dialectical Behaviour Therapy (DBT) for individuals with eating disorders and borderline personality disorder.

Multidisciplinary teams, including psychiatrists, psychologists, dietitians, and social workers, provide holistic care, with each professional managing different aspects of the patient’s health. Lastly, support groups and peer support provide access to environments where individuals can share experiences and strategies for managing both eating disorders and co-occurring conditions, such as groups specifically for people with eating disorders and anxiety or dual diagnosis groups for those with substance abuse issues.
