Have you ever wondered why some wounds remain hidden, even from those closest to us?
In the intricate tapestry of mental health, eating disorders often intertwine with the threads of trauma, creating a complex pattern that many struggle to unravel.
"Eating Disorders and Trauma: Breaking the Silence" isn't just a title—it's a call to action.
As we peel back the layers of shame and secrecy, we uncover a truth that's both unsettling and empowering: the connection between our past experiences and our relationship with food is profound and often misunderstood. In this exploration, we'll shine a light on the shadows where cognitive distortions lurk and examine how cultural factors can either perpetuate or heal these conditions.
Whether you're a mental health professional seeking new insights, a family member trying to understand, or someone grappling with these issues personally, this journey is for you. Are you ready to challenge the silence and embrace a new understanding? Let's begin this crucial conversation together.
The Neurobiology of Trauma and Eating Disorders
The intricate relationship between trauma and eating disorders has its roots in the complex workings of the brain. Research has shed light on the neurobiological underpinnings of these conditions, revealing how traumatic experiences can alter brain function and contribute to the development of eating disorders.
Brain Structure Alterations
Trauma and eating disorders can have a significant impact on brain structure. Studies have shown that individuals with eating disorders, such as anorexia nervosa and bulimia, often exhibit specific neurobiological differences compared to those without these conditions. These variances affect not only eating behaviours but also mood, personality, anxiety levels, and decision-making processes.
Neurotransmitter Imbalances
Neurotransmitters, the chemical messengers in the brain, play a crucial role in the development and maintenance of eating disorders. Research indicates that chemical imbalances within the brain can have a substantial effect on the behaviour, recovery, and reactions of those with eating disorders.
Serotonin
Serotonin, also known as 5-hydroxytryptophan, is a neurotransmitter that helps regulate mood, feelings of well-being, and happiness. It also impacts sleep, eating, and digestion.
Geneticists have found that people with anorexia are more likely to carry a variant of the 5HT2A receptor, which is thought to increase the amount of serotonin in the non-starved state.
This overproduction of serotonin can lead to a continual state of acute stress and anxiety.
Dopamine
Dopamine, another crucial neurotransmitter, is associated with pleasure, reward, and motivation. In individuals with anorexia, a leading hypothesis suggests that the disorder is linked to an overproduction of dopamine. This excess can lead to anxiety, harm avoidance, hyperactivity, and the ability to go without pleasurable things like food.
Cortisol
Cortisol, a steroid hormone that helps regulate stress response, immune function, and metabolism, can be chronically elevated in people with eating disorders due to starvation. This increased cortisol can result in decreased appetite, as it inhibits the release of appetite stimulants.
Epigenetic Changes
Epigenetics, which studies how environmental factors can influence gene expression without altering the DNA sequence, has emerged as a promising field in understanding eating disorders. Epigenetic processes are dynamically influenced by environmental stimuli such as stress, nutritional status, and medication intake 2.
These changes are highly relevant to eating disorders as they represent potential mechanisms that connect genetic predisposition with environmental factors like stress, nutrition, and traumatic events 2. Research has shown that early life stress, often associated with eating disorders, can lead to epigenetic changes 3. However, empirical evidence confirming this association in humans is limited due to the low availability of brain tissue and the scarcity of large longitudinal studies 3.
Epigenome-wide association studies (EWASs) have emerged as a promising avenue for future research. These studies analyse DNA methylation across the genome in patients with eating disorders to identify potential disease-relevant changes in gene regulation 2. To date, five EWASs on anorexia nervosa have been published, suggesting the potential reversibility of malnutrition-induced epigenetic changes once patients recover 2.
Understanding these neurobiological aspects of eating disorders and trauma can pave the way for more effective treatments and interventions. As research in this field continues to advance, it holds the potential to aid in disentangling the molecular genetic pathways that contribute to the development and progression of these complex conditions 3.
Emotion Regulation in Traumatised Eating Disorder Patients
Emotion regulation plays a crucial role in the development and maintenance of eating disorders, especially in individuals with a history of trauma. The ability to identify and modulate emotional experiences has emerged as a potential transdiagnostic therapeutic target for eating disorder patients 4.
Alexithymia
Alexithymia, characterised by difficulty in identifying and describing feelings, has a strong association with eating disorders. Research has shown that eating disorder patients are more likely to exhibit alexithymia compared to the general population 5.
This connection has significant implications for treatment outcomes, as difficulty in identifying feelings can act as a negative prognostic factor in the long-term outcomes of eating disorders 5.
The relationship between alexithymia and eating disorders is complex. Even when food-related abnormal behaviours have subsided, eating disorder patients may continue to score high on measures of alexithymia 5. This suggests that alexithymia may be a persistent trait in individuals with eating disorders, rather than a temporary state linked to disordered eating behaviours.
Interestingly, the cognitive component of alexithymia does not appear to be directly related to eating disorders 5. This has led researchers to propose that the relationship between eating disorders and alexithymia may be mediated by a third factor, such as affective disorders 5.
Distress Tolerance
Distress tolerance, defined as the ability to navigate stressful situations without becoming emotionally dysregulated, is a crucial skill for individuals with eating disorders. People with low distress tolerance can become easily overwhelmed by stressors and may turn to harmful coping mechanisms, including disordered eating behaviours 6.
Many eating disorder behaviours can manifest during times of emotional distress. For example, some individuals may use food for comfort during emotionally overwhelming periods, while others might engage in compulsive or intense exercise to quiet negative emotions 6. Developing distress tolerance skills can help build better ways of regulating intense emotions, enabling individuals to cope more effectively with difficult situations. These skills can help someone return to a state of emotional equilibrium more quickly, encouraging more measured thoughts and behaviours 6.
Emotional Avoidance
Emotional avoidance is a common coping mechanism used by individuals with eating disorders, particularly those with a history of trauma. Eating disorder symptoms often serve as a means of escaping or reducing awareness of traumatic experiences and associated emotions 7.
Research has shown that approximately 75% of women enrolled in residential treatment for eating disorders admit to experiencing some form of trauma, with 50% having a history of post-traumatic stress disorder (PTSD) 7.
This high prevalence underscores the significant role that trauma plays in the development and maintenance of eating disorders. Eating disorders often develop as a coping mechanism or means of self-protection following traumatic experiences. The behaviours associated with these disorders can serve as a way to control one aspect of an individual's life when they feel powerless or out of control due to past trauma 7.
To address these complex issues, treatment approaches often focus on uncovering the emotions associated with traumatic events. Dialectical Behaviour Therapy (DBT) has emerged as a promising approach for addressing both emotion regulation difficulties and trauma-related symptoms in individuals with eating disorders 7.
The Role of Shame in Trauma and Eating Disorders
Shame plays a significant role in the development and maintenance of eating disorders, particularly in individuals with a history of trauma. This deep-seated emotion can have a profound impact on one's self-worth and behaviour, often leading to destructive patterns of thought and action.
Origins of Shame
Shame is a complex emotion that stems from a variety of sources, often rooted in early life experiences. For many individuals with eating disorders, shame originates from childhood trauma or adverse parenting styles 8. These early experiences can shape a person's self-perception and contribute to the development of shame-based beliefs.
Childhood trauma, including neglect, physical abuse, and sexual abuse, has been identified as a risk factor for developing eating disorders 9. These traumatic experiences can lead to a perceived loss of control, which individuals may attempt to regain through disordered eating behaviours 9.
Research has shown that childhood sexual abuse (CSA) is linked to the development of eating disorders, as it can significantly affect one's identity and body image 9.
In cases where individuals don't report severe trauma, factors such as critical or demanding parents and experiences of bullying at school can contribute to the development of shame and perfectionism 8. These early shame experiences can become encoded as traumatic memories, eliciting symptoms of intrusion, hyperarousal, and avoidance 10.
Maintaining Factors
Shame acts as a powerful maintaining factor in eating disorders, creating a cyclical relationship between negative self-perception and disordered eating behaviours. This cycle can be particularly challenging to break, as shame often touches all aspects of an individual's life, leading to feelings of worthlessness and a sense of being 'second rate' in comparison to others 8.
One of the key ways shame perpetuates eating disorders is through the development of shame scripts. These are internalised, self-deprecating stories that individuals carry with them, often involving recurring thoughts such as "I'm not good enough" or "I'm unlovable" 11. These deeply ingrained beliefs can dictate behaviours, decisions, and interactions with the world.
In the context of eating disorders, shame scripts can fuel cycles of shame and guilt. They may tell individuals that they deserve suffering or punishment and that their worth is tied to their ability to control their eating or appearance 11. This creates a destructive cycle where eating disorder behaviours serve as both a coping mechanism and a reinforcement of the shame script.
Perfectionism, often closely linked with shame, can also play a significant role in maintaining eating disorders. Individuals may strive for perfectionism in every area of life, including diet, exercise regime, and body shape, in an attempt to alleviate feelings of shame and feel 'good enough' 8. However, this pursuit of perfection is often unachievable, leading to intense feelings of shame when standards are not met, thus perpetuating the cycle.
Shame-Based Interventions
Recognising the central role of shame in eating disorders has led to the development of shame-based interventions. These approaches aim to address the underlying shame and trauma that contribute to disordered eating behaviours.
One important aspect of these interventions is working directly with shame memories, focusing on diminishing their traumatic nature and reconstructing their central meaning to self-identity 10. This can help individuals develop a more compassionate and balanced self-perception.
Practitioners may also focus on addressing the impact of early shame experiences involving peers and other social agents. These experiences can become traumatic memories central to self-identity and contribute to perceptions of inferiority and core psychopathology features in eating disorder patients 10.
Additionally, interventions may target the development of healthier coping mechanisms for emotional distress. Many individuals with eating disorders report using food restriction as a way to convert emotional pain into physical pain, which they feel is easier to manage 8. By addressing these underlying emotional regulation difficulties, interventions can help individuals develop more adaptive ways of coping with distress.
Trauma-Related Cognitive Distortions in Eating Disorders
Trauma and eating disorders often intertwine, creating a complex web of cognitive distortions that can perpetuate disordered eating behaviours. Understanding these distortions is crucial for effective treatment and recovery.
Core Beliefs
Core beliefs play a significant role in the development and maintenance of eating disorders, especially in individuals with a history of trauma. These deeply ingrained assumptions about ourselves, others, and the world around us often develop in childhood and can have a profound impact on our thoughts and behaviours 12.
Research has shown that individuals with eating disorders tend to have more negative core beliefs compared to those without such disorders.
A study involving 106 subjects with eating disorders and 27 without found a direct relationship between the type and severity of eating disorders and core beliefs. Participants with anorexia and bulimia were found to have the highest number of maladaptive beliefs 12.
Some common negative core beliefs associated with eating disorders include:
Defectiveness/shame
Insufficient self-control
Failure to achieve
Emotional deprivation
Abandonment/instability
These beliefs can act as philtres, causing individuals to pay attention to information that supports their negative self-perceptions while ignoring evidence to the contrary 13.
Thought Suppression
Thought suppression is a common cognitive distortion in individuals with eating disorders and a history of trauma. This involves attempting to push away or avoid unwanted thoughts and emotions, often related to traumatic experiences or negative self-perceptions.
Research has shown that thought suppression can be counterproductive, leading to an increase in the very thoughts and emotions one is trying to avoid. In the context of eating disorders, this can manifest as:
Binge eating to reduce overwhelming emotions
Purging to escape negative thoughts about oneself and feelings of shame
A study conducted at the University of London found that the frequency of binge eating was connected to beliefs about emotional inhibition, while vomiting was linked to beliefs about defectiveness and shame 12.
Cognitive Restructuring Techniques
Cognitive restructuring is a key component of Cognitive Behavioural Therapy (CBT), which has been shown to be effective in treating eating disorders 14. This process involves identifying and challenging negative thought patterns and core beliefs, replacing them with more balanced and realistic perspectives.
Some cognitive restructuring techniques used in the treatment of eating disorders include:
Challenging dietary rules: Identifying and behaviorally challenging rigid food-related rules, such as not eating after 8 p.m. or avoiding certain food groups.
Developing continuum thinking: Replacing all-or-nothing thinking with more nuanced perspectives.
Using behavioural experiments: Encouraging individuals to test their beliefs about food and weight gain through controlled experiments.
Keeping food records: Documenting eating habits, thoughts, and feelings to identify patterns and triggers.
Exposure to fear foods: Gradually reintroducing foods that the individual fears or avoids.
These techniques help individuals to identify and modify the cognitive distortions that maintain their eating disorder. By addressing the underlying core beliefs and thought patterns, individuals can develop a healthier relationship with food, their bodies, and themselves.
Interoceptive Awareness in Trauma and Eating Disorders
Interoceptive awareness, the ability to perceive and interpret internal bodily sensations, plays a crucial role in the relationship between trauma and eating disorders. Individuals who have experienced trauma often struggle with maintaining a healthy connection to their bodies, which can contribute to the development and maintenance of eating disorders.
Body Disconnection
People with eating disorders frequently experience a lack of connection with their bodies. This disconnection can stem from various factors, with trauma being a significant contributor.
Research has shown that approximately 25% of individuals with eating disorders also have post-traumatic stress disorder (PTSD).
One of the symptoms of trauma is dissociation, a state of being disconnected from one's body or reality. Eating disorders often require individuals to remain disconnected from their bodies to engage in disordered eating behaviours. This disconnection goes against natural physical impulses, making it essential for individuals to detach from their bodily sensations to maintain their eating disorder patterns.
Mindfulness-Based Approaches
Mindfulness-based interventions have gained increasing support as effective approaches to encourage nonjudgmental acceptance of experiences 15. These interventions emphasise skills and techniques that facilitate increased acceptance of internal experiences, including thoughts, feelings, and physical sensations 7.
Mindfulness-based treatments (MBT) can target the cognitions that initiate and maintain disordered eating 9. By incorporating mindfulness into the treatment of eating disorders, individuals can cultivate awareness of internal experiences, facilitate self-acceptance, increase cognitive flexibility, and improve their ability to cope adaptively with emotions.
One such approach is Mindfulness-Based Cognitive Therapy (MBCT), which combines techniques from cognitive behavioural therapy with mindfulness strategies. MBCT helps patients better understand and manage their thoughts and emotions, potentially freeing themselves from disordered eating patterns.
Studies have shown that after MBCT, individuals experienced significant improvements in four out of five facets of mindfulness: observing, describing, nonjudging of inner experience, and nonreactivity to inner experience 16. Additionally, MBCT has been found to improve eating behaviours, reduce depressive mood, and decrease trait anxiety 16.
Sensorimotor Psychotherapy
Sensorimotor Psychotherapy (SP) is a method that draws upon the natural wisdom of the body to tap into the innate drive for healing, adaptation, and development of new capacities. This approach focuses on the body's movement, posture, and sensation to help individuals reconnect with their bodies and process trauma.
SP is particularly helpful in working with the effects of trauma, relational trauma, and difficult past attachment relationships. By addressing body, emotions, and thoughts simultaneously, SP promotes physical, psychological, and spiritual well-being.
The therapy is conducted in three phases:
Awareness and mindfulness: Clients are guided to become aware of their current inner experiences, including memories, images, emotions, thoughts, and bodily patterns.
Processing traumatic memories: Clients develop new resources to help integrate painful events from the past, using techniques such as dual awareness to address small pieces of state-specific memories without reliving the entire traumatic experience.
Integration and relationship exploration: Clients address the legacy of their relationship history, including early attachment relationships with caregivers. They explore limiting beliefs, practise expressing emotions, and work on improving connexions and intimacy.
By incorporating these approaches, individuals with trauma and eating disorders can begin to rebuild their interoceptive awareness, fostering a healthier relationship with their bodies and emotions. This integration of mind and body-based therapies offers a comprehensive approach to healing, addressing both the psychological and physiological aspects of trauma and eating disorders.
Self-Harm and Suicidality in Traumatised Eating Disorder Patients
Prevalence Rates
Eating disorders are among the most lethal mental health diagnoses, with a significantly elevated risk of suicidality not only for those meeting full diagnostic criteria but also for individuals reporting body dissatisfaction and engaging in subclinical disordered eating behaviours. Nearly half of individuals with eating disorders report suicidal ideation 17.
A systematic review and meta-analysis found that, on average, 27% of patients with eating disorders have a history of self-harm 18.
The risk of self-harm is estimated to be over seven times higher in those with eating disorders compared to the general population 18. This risk is even more pronounced in specialist eating disorder settings, where patients are approximately three times more likely to report a history of self-harm compared to those in general practice and community settings 18.
Risk Factors
Several factors contribute to the increased risk of self-harm and suicidality in individuals with eating disorders, particularly those with a history of trauma. Research has consistently shown a strong association between eating disorders and self-injury among individuals who report a history of trauma and abuse, including verbal, emotional, neglectful, physical, sexual, and substance abuse 19.
Co-occurring mental health conditions, such as depression and anxiety, further elevate the risk. Individuals with eating disorders who engage in self-harm often exhibit more severe eating disorder pathology. For instance, those who reported self-injury had higher Eating Disorder Inventory scores, indicating greater severity of eating disorder symptoms 19.
Specific eating disorder behaviours, particularly those involving binge or purge behaviours (e.g., anorexia nervosa-binge/purge subtype and bulimia nervosa), have been associated with a significantly higher number of types of non-suicidal self-injury, including cutting, scratching, bruising, and burning 19.
Safety Planning
Given the high risk of self-harm and suicidality in traumatised eating disorder patients, implementing effective safety planning strategies is crucial. Suicide safety planning (SSP) has emerged as a collaborative approach between service providers and individuals at risk of suicide 20. This method was developed in response to the recognition that "contracting for safety" was largely ineffective in mitigating suicide risk 20.
SSP aligns closely with the values of person-centred care and emphasises collaboration between the healthcare provider and the patient. The process involves developing a crisis plan that the client can follow when experiencing suicidal thoughts or urges 17. For clients with a high risk of suicidality, admission to a crisis centre or local emergency room may be indicated unless immediate action can be taken to significantly reduce risk and ensure safety 17.
Therapeutic interventions should aim to reduce pain, instil hope, foster connection, and decrease the capacity to act on suicidal thoughts 17. It's essential to identify both internal and external protective factors during the assessment process, as these serve as buffers against acting on suicidal thoughts and urges 17.
Cultural Considerations in Trauma and Eating Disorders
Racial Trauma
The impact of racial and ethnic discrimination on mental health, including eating disorders, has become increasingly apparent. Research has shown that experiencing racial harassment and taunts can over-activate the stress response, leading to increased and prolonged exposure to stress hormones and oxidative stress 21. This chronic stress can have cascading effects on both psychological and physical health.
A growing body of literature has found significant associations between racial discrimination and binge eating disorder (BED), particularly among Latino and African American adults 21. In a national study of early adolescents in the U.S., experiencing racial/ethnic discrimination was associated with higher odds of binge-eating behaviours and diagnosis, even after adjusting for confounding factors such as race, sex, nativity, parental education, and socioeconomic status 22.
The prevalence of eating disorders, such as anorexia nervosa or bulimia nervosa, differs between white individuals and people of colour 23. Moreover, the presentation and symptoms of eating disorders are observed to be heterogeneous among racial and ethnic groups 23. This diversity in presentation highlights the need for culturally sensitive approaches to diagnosis and treatment.
Acculturation Stress
Acculturation, the process of cultural change that occurs when two or more cultural identities interact, can contribute to the susceptibility of developing an eating disorder 24. Western culture's emphasis on physical appearance and thinness can increase pressure to attain a thin body through excessive dieting and potential engagement in eating disorder behaviours 24.
The process of acculturation often involves significant stressors, including:
Learning a new language
Adjusting to different societal norms
Navigating familial disagreements
Coping with different levels of acculturation between generations within the family unit
These stressors may lead to various psychological difficulties and the use of disordered eating behaviours as a coping mechanism 24. Intergenerational conflict, resulting from an acculturation gap among family members, can be particularly challenging. While acculturation itself may not directly predict psychological distress, familial conflict due to cultural differences has been shown to contribute to increased psychological distress 24.
Culturally-Adapted Treatments
Recognising the importance of cultural factors in the development and treatment of eating disorders, there is a growing emphasis on culturally-adapted interventions.
Mental health professionals should aim to increase their understanding of cultural differences, acknowledge their own cultural biases and assumptions, and be willing to make changes in their thoughts, attitudes, and behaviours to address pre-existing biases and stereotypes 23.
Culturally-adapted treatments can include:
Coordination with alternative medicine or community leaders
Addressing potential barriers to accessing treatment, such as stigma and healthcare disparities
Communicating with clients about their cultural context to better understand cultural norms and behaviours
Conducting comprehensive assessments of how culture may impact eating disorders
Adopting a strong therapeutic alliance through collaboration and non-judgmental approaches
Recognising nuances that may impact clinical presentations
Exploring the individual's social circumstances, such as family support
Providing psychoeducation about eating disorders
Exploring how ethnic identity, acculturation, and acculturative stress may contribute as risk or protective factors
To enhance cultural competence, clinicians should consult with minority ethnicities, provide constant self-assessment, and identify resources relevant to the racial identities of their clients. The inclusion of mental health professionals from diverse backgrounds is also crucial, as they can be more sensitive to the specific therapeutic needs of cultural minority groups 23.
By recognising how culture influences the presentation of symptoms and accounting for these factors in treatment, clinicians can provide more person-centred support. Treatments can be culturally adapted in areas such as language, persons involved, metaphors, content, concepts, methods, and goals 23.
Conclusion
The intricate relationship between trauma and eating disorders highlights the complex interplay of neurobiological, emotional, and cognitive factors. This exploration has shed light on the profound impact of shame, cognitive distortions, and cultural considerations in shaping these conditions. By understanding these connexions, we can develop more effective, person-centred approaches to treatment and recovery.
Moving forward, it's crucial to continue breaking the silence surrounding trauma and eating disorders. This means fostering open dialogues, promoting culturally sensitive interventions, and empowering individuals to seek help. By addressing these issues with compassion and understanding, we can pave the way for healing and resilience, offering hope to those grappling with the challenging journey of recovery.
