Binge-eating disorder

Binge-eating disorder is common but under-recognized; case questions test whether the counselor separates it from bulimia and depression and treats it as a clinical condition, not a willpower problem.

Criteria at exam depth (paraphrased):

• Recurrent binge eating: eating, in a discrete period, an amount clearly larger than most people would, with a sense of loss of control.
• Binges are associated with three or more of: eating much more rapidly than normal; eating until uncomfortably full; eating large amounts when not physically hungry; eating alone because of embarrassment; feeling disgusted, depressed, or very guilty afterward.
• Marked distress about bingeing.
• Binges occur at least once a week for 3 months.
• No regular inappropriate compensatory behavior, and the disturbance does not occur only during bulimia or anorexia.
• Severity by binge episodes per week: mild 1–3, moderate 4–7, severe 8–13, extreme 14 or more.
• Body weight is not a criterion; the disorder occurs across weights.

Hinge differentials:

• Bulimia nervosa — regular compensatory behavior (vomiting, laxatives, fasting, excessive exercise).
• Major depression with increased appetite — overeating occurs within a depressive episode with sustained low mood or anhedonia and without discrete loss-of-control binges.
• Night eating syndrome — eating after awakening at night or excess evening intake with awareness and recall, rather than discrete binges with loss of control.
• Obesity — not a mental disorder; many people with higher weight do not binge.
• Borderline personality disorder — bingeing within a broader pattern of impulsivity; may co-diagnose.

On the NCMHCE: Screen for depression, anxiety, substance use, and suicide risk, which commonly co-occur. Refer for medical evaluation of related health conditions. Provide psychoeducation that binge-eating disorder is a recognized clinical condition, which counters shame and the belief that it is a lack of willpower. Assess dieting history: restrictive dieting often intensifies binge urges, so failed diets inform the plan rather than signal noncompliance. First-line psychotherapies are CBT (regular eating pattern, self-monitoring, trigger and emotion work) and interpersonal psychotherapy, which targets the link between relationship stress and binges. Medication can be a referral topic for medical evaluation. Watch for weight stigma in the client's history and in the counselor's own assumptions.

Clinical Pearl: Weekly binges for 3 months with distress and no compensation equals binge-eating disorder. Treat dieting as a trigger, not a solution.
