Eating Disorders
Feeding and Eating Disorders (DSM-5-TR)
Severe disturbances in eating behaviors and related thoughts/emotions. Includes anorexia nervosa, bulimia nervosa, binge eating disorder, and ARFID. FBT is gold standard for adolescent anorexia; CBT-E leads for bulimia and BED.
Prevalence: Estimates vary by method: ~2% of US adults for anorexia, bulimia, and binge eating disorder combined (NESARC-III), against ~8.4% of women and ~2.2% of men once broader diagnoses are counted (Galmiche et al., 2019). Anorexia carries among the highest mortality of any psychiatric disorder
Clinical Picture
Anorexia carries one of the highest mortality rates in psychiatry, with a standardized mortality ratio around 5.9; among mental disorders only substance use, and opioid use in particular, clearly exceeds it. Eating disorders are also among the most complex conditions to treat. They interweave body image, identity, control, family dynamics, cultural pressures, trauma history, and neurobiological factors in ways that resist simple formulation. Anorexia, bulimia, binge eating disorder, and ARFID are distinct conditions with different clinical profiles and evidence bases. The therapist must navigate the tension between the medical urgency of nutritional restoration and the psychological work of understanding what the eating disorder means and does for the client.
Treatment Considerations
Psychotherapy for a restricting or purging eating disorder is never the whole treatment. Medical monitoring runs alongside it (vital signs, weight trajectory, electrolytes) with agreed thresholds for stepping up to a higher level of care, and refeeding a severely malnourished client is a medical procedure carrying real risk of refeeding syndrome, not something therapy accomplishes on its own. A trainee holding one of these cases needs a physician or dietitian in the picture from the start. With that in place: for adolescent anorexia, Family-Based Treatment (FBT/Maudsley) has the strongest evidence. For adult bulimia and binge eating, CBT-E (Enhanced) is the first-line treatment. For anorexia in adults, no single approach has clearly superior outcomes: CBT-E, SSCM, and psychodynamic approaches show similar results, which may reflect the difficulty of the condition rather than treatment equivalence. Many eating disorder specialists integrate multiple approaches. DBT-informed approaches are increasingly used for the emotional dysregulation component. Body-oriented and somatic approaches may address the lived-body dimension that purely cognitive approaches miss.
