Treating eating disorders in primary care.

Area of Science:

• Psychiatry and Behavioral Science
• Internal Medicine
• Clinical Psychology

Background:

• Eating disorders, including anorexia nervosa, bulimia nervosa, and binge-eating disorder, are serious conditions with complex psychosocial and medical components.
• Effective management hinges on a robust physician-patient therapeutic alliance to accurately assess patient needs and determine the appropriate care setting.

Purpose of the Study:

• To outline the assessment and treatment approaches for patients presenting with anorexia nervosa, bulimia nervosa, and binge-eating disorder.
• To delineate criteria for outpatient versus inpatient care based on medical stability and psychiatric risk.

Main Methods:

• Review of current evidence-based treatment modalities for eating disorders.
• Clinical guidelines for determining the level of care, distinguishing between outpatient and inpatient settings.
• Identification of psychotherapeutic and pharmacologic interventions with supporting evidence.

Main Results:

• Outpatient treatment, involving a multidisciplinary team (physician, dietitian, therapist), is suitable for most patients.
• Inpatient care is indicated for patients with suicidal ideation or life-threatening medical complications (e.g., severe bradycardia, electrolyte imbalances, organ compromise, or body weight <85% of healthy).
• Interpersonal therapy, cognitive behavioral therapy, and antidepressants show efficacy for binge-eating disorder and bulimia nervosa; guided self-help may be a first step.
• Evidence for behavioral or pharmacologic treatments for anorexia nervosa remains limited.

Conclusions:

• A collaborative, multidisciplinary approach is crucial for managing eating disorders.
• Treatment intensity should be tailored to individual medical and psychosocial needs, with clear indications for inpatient admission.
• Further research is needed to establish effective treatments for anorexia nervosa.
