Introduction
Binge-Eating Disorder (BED) is the most common eating disorder in the United States, characterized by recurrent episodes of consuming large amounts of food in a short period accompanied by a sense of loss of control and significant emotional distress. Unlike bulimia nervosa, BED does not involve regular compensatory behaviors such as purging, and it is associated with serious physical and psychological health consequences.
Causes
BED is influenced by a combination of genetic, psychological, and environmental factors. A history of dieting, weight stigma, trauma, depression, anxiety, or low self-esteem increases risk. Neurobiological factors affecting hunger, reward, and impulse control pathways in the brain also play a role. Cultural pressures around body image and a history of emotional eating may further contribute to its development.
Symptoms
Symptoms include recurrent episodes of eating unusually large amounts of food within a two-hour period, eating rapidly and beyond the point of fullness, eating when not physically hungry, eating alone due to embarrassment about quantity, and experiencing intense guilt, shame, or disgust after eating. These episodes occur at least once a week for three months and cause marked distress.
Diagnosis
A clinician diagnoses BED using DSM-5 criteria, which require recurrent binge-eating episodes associated with at least three of five specific features (e.g., eating faster than normal, eating until uncomfortably full, eating alone due to shame), occurring at least once per week for three months, with no regular compensatory behaviors. Medical evaluation may also be needed to assess weight-related health complications.
Treatment
Cognitive behavioral therapy (CBT) is the gold-standard treatment for BED, helping patients identify triggers, develop healthier coping strategies, and change patterns of disordered eating. Interpersonal therapy and dialectical behavior therapy (DBT) are also effective. Medications such as lisdexamfetamine (approved specifically for BED) or antidepressants may be used alongside therapy to reduce binge-eating frequency and severity.
