Introduction

Eating disorders represent a multifaceted challenge to both the individual’s physical health and psychological well-being, with their origins deeply rooted in the interplay of biological, psychological, and social factors [1]. Anorexia nervosa, bulimia nervosa, and binge-eating disorder are complex mental health conditions that extend beyond mere disturbances in eating habits, delving into intricate relationships with genetic predispositions, neurobiological intricacies, psychological vulnerabilities, and societal influences [2]. In this comprehensive review, we embark on a journey to unravel the interconnected web of factors that contribute to the onset, perpetuation, and manifestation of eating disorders [3]. While the prevalence of eating disorders continues to rise, the understanding of their etiology remains elusive and challenging. It is evident that no single factor can adequately account for the complexity of these disorders. Instead, it is the convergence and interaction of biological, psychological, and social elements that shape the landscape of eating disorders [4]. Recognizing the need for a holistic perspective, this review aims to synthesize current knowledge from diverse disciplines, offering insights that pave the way for a more nuanced comprehension of these debilitating conditions [5]. Biological factors, encompassing genetic predispositions, neurobiological underpinnings, and hormonal influences, set the foundation for the vulnerabilities that individuals may possess. Concurrently, psychological factors such as body image dissatisfaction, perfectionism, and self-esteem intricately weave into the narrative, influencing thoughts, emotions, and behaviors [6]. Moreover, the socio-cultural environment, family dynamics, and peer influences form the social context within which these disorders manifest and evolve. As we delve into this comprehensive exploration, our goal is to not only elucidate the complex interplay of these factors but also to underscore the importance of an integrated biopsychosocial model in understanding eating disorders [7]. By gaining a deeper comprehension of the synergistic influences at play, we aim to inform targeted interventions, treatment approaches, and prevention strategies [8]. Through this journey, we aspire to contribute to the evolving dialogue surrounding eating disorders, fostering collaborative efforts among healthcare professionals, researchers, and policymakers to address the multifaceted nature of these conditions and improve the lives of those affected [9].

Biological factors

Genetic predispositions, neurobiological factors, and hormonal influences play pivotal roles in the development of eating disorders [10]. Recent research has identified specific genetic markers associated with susceptibility to these disorders. Additionally, dysregulation in neurotransmitter systems, particularly serotonin and dopamine, has been implicated in the pathophysiology of eating disorders. Hormonal imbalances, such as disruptions in the ghrelin-leptin axis, further contribute to aberrant eating behaviors.

Psychological factors

Psychological factors play a pivotal role in the intricate tapestry of eating disorders, influencing an individual’s thoughts, emotions, and behaviors. Central to this is the pervasive issue of body image dissatisfaction, wherein distorted perceptions of one’s own body contribute significantly to the development and perpetuation of disordered eating patterns. Societal pressures, perpetuated by media portrayals of an idealized body, can fuel a relentless pursuit of thinness, fostering negative body image. Additionally, the relentless pursuit of perfectionism, whether self-imposed or driven by external expectations, creates an environment conducive to obsessive dieting, rigid exercise regimens, and an overall maladaptive relationship with food. Low selfesteem, often interwoven with body image concerns and perfectionistic tendencies, further amplifies vulnerability to the development of eating disorders. As we unravel the psychological dimensions, it becomes apparent that addressing these factors is essential for a comprehensive understanding of eating disorders and the development of effective therapeutic interventions.

Social factors

The socio-cultural environment, family dynamics, and peer influences contribute to the complexity of eating disorders. Cultural emphasis on thinness, societal beauty standards, and media portrayal of body ideals play a role in shaping individuals’ perceptions of their bodies. Family dynamics, including parental attitudes toward food and weight, can impact the development of disordered eating patterns. Peer interactions and societal norms further influence individuals susceptible to eating disorders.

Integrated models and treatment implications

The complex and interconnected nature of eating disorders necessitates a comprehensive and integrated approach to treatment. Recognizing that these conditions are not solely determined by one factor, researchers and healthcare professionals advocate for biopsychosocial models that consider the interplay of biological, psychological, and social factors. In the realm of biological interventions, medical management addressing nutritional deficiencies and associated health complications is crucial. Psychologically, psychotherapy, including cognitive-behavioral therapy (CBT) and dialectical behavior therapy (DBT), proves effective in addressing distorted thought patterns and maladaptive behaviors. Additionally, nutritional counseling helps individuals establish healthy relationships with food. Socially, interventions may involve family therapy to address familial dynamics and support networks, as well as communitybased programs aimed at promoting body positivity and healthy lifestyle norms. Early detection and intervention are paramount, as the severity and chronicity of eating disorders often correlate with delayed treatment. Moreover, prevention programs that target at-risk populations, including adolescents exposed to societal pressures and those with genetic predispositions, are crucial for reducing the overall prevalence of these disorders. Collaborative efforts between healthcare providers, mental health professionals, educators, and policymakers are essential to develop and implement comprehensive strategies that encompass prevention, early intervention, and ongoing support. By adopting an integrated model that considers the intricate interplay of biological, psychological, and social elements, the treatment landscape for eating disorders can be transformed, offering individuals a more holistic path to recovery and improved quality of life.

Conclusion

This comprehensive review highlights the intricate interplay of biological, psychological, and social factors in eating disorders. A nuanced understanding of these factors is essential for the development of targeted interventions and prevention strategies. By addressing the multifaceted nature of eating disorders, healthcare professionals, researchers, and policymakers can work collaboratively to improve outcomes for individuals affected by these debilitating conditions.
