Symptoms and Signs of Binge Eating Disorder
During a binge episode, people eat a much larger amount of food than most people would eat in a similar time under similar circumstances. During and after a binge, people feel as if they have lost control. Binge eating is not followed by purging (by inducing vomiting, misusing laxatives, diuretics, or enemas), excessive exercising, or fasting. Binge eating occurs in episodes; it does not involve constant overeating ("grazing").
People with binge eating disorder are distressed by it.

Treatment of Binge Eating Disorder
Cognitive behavioral therapy
Sometimes interpersonal psychotherapy
Consideration of drug therapy, usually selective serotonin reuptake inhibitors (SSRIs) or lisdexamfetamine
Cognitive behavioral therapy is the most studied and best supported treatment for binge eating disorder, but interpersonal psychotherapy appears equally effective. Both result in remission rates of ≥ 60%, and improvement is usually well-maintained over the long term. These treatments do not produce significant weight loss in patients with obesity.
Conventional behavioral weight-loss treatment has short-term effectiveness in reducing binge eating, but patients tend to relapse. Antidepressant drugs (eg, SSRIs Selective Serotonin Reuptake Inhibitors (SSRIs) Several drug classes and drugs can be used to treat depression: Selective serotonin reuptake inhibitors (SSRIs) Serotonin modulators (5-HT2 blockers) Serotonin-norepinephrine reuptake inhibitors... read more ) also have short-term effectiveness in eliminating binge eating, but long-term effectiveness is unknown. Lisdexamfetamine is approved for the treatment of moderate to severe binge eating disorder. It can reduce the number of binge days and appears to cause slight weight loss, but its long-term effectiveness is unknown. Appetite-suppressing drugs (eg, topiramate) or weight-loss drugs (eg, orlistat) may be helpful.
People with binge eating disorder have episodes of consuming large quantities of food, do not compensate by vomiting or purging, and tend to have overweight or obesity.
Diagnose binge eating disorder based on clinical criteria (including binge eating, on average, at least once/week for 3 months, with a sense of lack of control over eating).
Treat with cognitive behavioral therapy or interpersonal psychotherapy and sometimes drugs (eg, SSRIs, lisdexamfetamine).
