Background <p>Health professionals are crucial to the treatment of patients with eating disorders, and their experiential knowledge is central for bridging the gap between research and clinical practice. This study investigated why health professionals enter the eating disorder field, the challenges and rewards they face, the characteristics they consider vital for treating patients, and their advice to newcomers.</p> Methods <p>Open-ended responses from 188 Nordic health professionals who work with eating disorders were collected via a cross-sectional online survey. Data were analyzed using quantitative and qualitative content analysis, and coding was conducted by multiple researchers using consensus procedures to enhance credibility and analytic rigor.</p> Results <p>Participants reported entering the eating disorder field due to interest in the subject, by coincidence, or a desire to help. Primary challenges were patient ambivalence, building therapeutic relationships, and systemic constraints. The most rewarding aspects were patient recovery, facilitating change, and the therapeutic relationship. Patience and warmth were the most important professional characteristics, followed by maturity and expertise. Advice to new professionals emphasized adopting a therapeutic stance grounded in patience and curiosity, building specialized knowledge about eating disorders, and seeking support through supervision.</p> Conclusions <p>These findings highlight the intertwined nature of challenges and rewards, and underscore the need to cultivate specific professional characteristics within supportive organizational contexts. By clarifying foundational conditions of day-to-day treatment, the results can inform workforce development, training, and healthcare service design to support retention and, in turn, high-quality treatment.</p>
