Objectives. This study aimed to comprehensively evaluate the impact of a multifaceted treatment approach, combining nutritional intervention, antipsychotic medication and psychotherapy, to the recovery of a female patient diagnosed with an eating disorder. The objective was to delineate how these integrated modalities contribute to improvements in both physical health and psychological well-being. Materials and method. A mixed-methods research design was employed. Quantitative data were gathered through weekly monitoring the patient’s body weight and weekly assessments of vital blood parameters, to objectively measure physical health progress. Qualitative data were collected using semi-structured interviews with the patient and her multidisciplinary healthcare team, including dietitians, psychologists and medical staff, providing insights into the psychological impact and patient’s experience of the treatment. Advanced data processing and visualization techniques were used, employing Microsoft Excel for the creation of comprehensive charts and graphs to analyze and present the data. Results. The results indicated a notable improvement in the patient’s overall health status, with significant gains in body weight and the stabilization of blood parameters. Psychologically, the patient demonstrated enhanced coping mechanisms and emotional well-being, as evidenced by her responses to RO-DBT and EMDR therapies. The nutritional intervention, tailored to her specific needs, along with the judicious use of antipsychotic medication played a key role in supporting her recovery. Conclusions. The study underscores the efficacy of an integrated treatment approach in managing eating disorders. The synergy between nutritional intervention, antipsychotic treatment and psychotherapy emerged as a crucial factor in addressing the complex interplay of physical and psychological aspects of the disorder. These findings contribute with valuable insights into the holistic management of eating disorders, highlighting the importance of personalized and comprehensive treatment strategies. This research adds to the existing body of knowledge, suggesting directions for future studies and clinical practices in the field of eating disorder treatment.
