Binge eating disorder: symptoms, treatment, and when to see a doctor
Last updated September 6, 2026.
**Binge eating disorder is a treatable mental health condition in which you repeatedly eat unusually large amounts of food in a short time and feel unable to stop.** The episodes are followed by distress, guilt, or shame, and unlike bulimia they are not regularly followed by vomiting, laxatives, fasting, or driven exercise. First-line treatment is a talking therapy, usually cognitive behavioral therapy built for eating disorders, with medication added when therapy alone is not enough. What changes urgency is not the eating itself but what comes with it: thoughts of suicide or self-harm, purging behaviors, or severe abdominal pain after a binge need care right away.
What are the symptoms of Binge eating disorder?
- Eating a much larger amount than most people would in about two hours, at least weekly
- Feeling that you cannot stop or control what or how much you are eating
- Eating much faster than usual, or until you are uncomfortably full
- Eating alone or hiding food because you feel embarrassed by the amount
- Feeling disgusted, depressed, guilty, or ashamed after an episode
- Eating when you are not physically hungry, often in the evening or at night
- Repeated dieting, weight cycling, or ongoing worry about weight and shape
Regular vomiting, laxative use, fasting, or heavy exercise to make up for eating points toward bulimia nervosa rather than binge eating disorder, and steady grazing across the day without a clear loss of control usually is not a binge.
How does a doctor diagnose Binge eating disorder?
Diagnosis is clinical and comes from your story, not from a scan or blood test. A clinician asks how often episodes happen, how much you eat in a defined stretch of time, whether you feel out of control during the episode, and how you feel afterward, then checks specifically for compensating behaviors such as vomiting, laxatives, diuretics, fasting, or exercise, since those point elsewhere. Binge eating disorder is diagnosed when binges occur on average at least once a week for three months, cause real distress, and are not regularly followed by compensating behavior. Brief screening questions like the SCOFF or the Binge Eating Scale are often used to start the conversation, and depression, anxiety, ADHD, trauma, and substance use are screened for because they frequently travel with it. Blood work does not confirm the diagnosis, but a clinician may check a metabolic panel, blood count, A1C, thyroid, and lipids to look for conditions that affect treatment, and may review medications such as steroids, antipsychotics, or mirtazapine that can drive appetite.
How is Binge eating disorder treated?
- Cognitive behavioral therapy: CBT designed for eating disorders (CBT-E) is first-line and typically runs about 16 to 20 sessions over four to five months. It targets rigid dieting, regular eating patterns, binge triggers, and shape and weight concerns, and it has the strongest evidence for stopping binges.
- Guided self-help: A structured CBT-based self-help book or program with short check-ins from a clinician is a reasonable first step for milder cases and is often offered while you wait for full therapy. It usually runs several weeks to a few months.
- Other talking therapies: Interpersonal psychotherapy and dialectical behavior therapy skills work are effective alternatives when CBT is unavailable, has not worked, or when relationship stress and emotion regulation are the main drivers.
- Medication: Lisdexamfetamine (Vyvanse) is FDA approved for moderate to severe binge eating disorder in adults and is usually started at 30 mg daily and adjusted to 50 to 70 mg. SSRIs such as fluoxetine or sertraline are an alternative, especially with depression or anxiety, and topiramate is used off label when other options fail. Medication works best alongside therapy, not instead of it.
- Care for related conditions: Depression, anxiety, ADHD, sleep apnea, and type 2 diabetes are treated in parallel, since untreated ADHD or poor sleep makes binges harder to control. Weight-focused dieting is generally held until binges are under control, because restriction tends to trigger more episodes.
When is Binge eating disorder an emergency?
Call 911 or go to the emergency room for severe abdominal pain with a swollen, hard, or tender belly after a large binge, especially with repeated vomiting, an inability to burp or vomit, or vomit that looks like blood or coffee grounds, since acute stomach dilation is rare but a surgical emergency. Also go to the ER for chest pain, fainting, a racing or irregular heartbeat, severe muscle weakness, or confusion, which can signal electrolyte problems if you have been purging or using laxatives. If you have thoughts of suicide or self-harm, call or text 988 (Suicide and Crisis Lifeline) now, and go to the ER if you feel unsafe. Use urgent care or a same-day office visit for persistent vomiting, dehydration, blood sugar over 300 mg/dL in diabetes, or binges that have become daily and unmanageable. Everything else, including binges once or twice a week without these signs, can be handled through a scheduled visit.

Common questions
How is binge eating disorder different from just overeating?
Almost everyone overeats sometimes, at holidays or after a long day. Binge eating disorder is defined by a clear loss of control during the episode, a much larger amount of food than most people would eat in a similar stretch of time, and real distress afterward. The episodes happen on average at least once a week for three months. Overeating at a big meal without that sense of not being able to stop, and without ongoing shame or distress, is not the same thing.
Do I have to be in a larger body to have binge eating disorder?
No. Binge eating disorder occurs across every body size, and many people with it are in a body size their doctor would call average. Weight is not part of the diagnostic criteria, and a normal weight does not rule it out. Clinicians diagnose it from the pattern of eating episodes and the loss of control, not from the scale.
Will treatment make me gain weight, or should I diet first?
Treatment aims first at stopping the binges, and for most people that means eating regular meals and snacks instead of restricting. Rigid dieting is one of the most reliable triggers for a binge, so starting a restrictive diet usually makes the cycle worse. Weight tends to stay stable or drift down modestly once binges stop. If weight management is a goal, it works better after the eating pattern is steady, and your clinician can sequence the two.
How long does treatment take to work?
With CBT for eating disorders, many people see binges drop noticeably within the first four to eight weeks, and a full course runs about 16 to 20 sessions over four to five months. Lisdexamfetamine often reduces binge days within the first few weeks at an effective dose. SSRIs usually need four to six weeks for a fair trial. Relapse is common at times of stress, so a written plan for what to do after a slip is part of good treatment.
Are the medications for binge eating disorder addictive?
Lisdexamfetamine is a stimulant and a controlled substance, so it carries a risk of misuse and is not appropriate if you have uncontrolled high blood pressure, certain heart conditions, or a history of stimulant misuse. Taken as prescribed and monitored, it is used safely for binge eating disorder in adults. It is not approved for weight loss. SSRIs such as fluoxetine and sertraline are not addictive, though stopping them abruptly can cause withdrawal symptoms, so they are tapered.
What can I start doing today, before I see anyone?
Eat three meals and two planned snacks at set times, and do not skip breakfast, since long gaps are the most common setup for an evening binge. Keep a simple log of what you ate, the time, where you were, and what you were feeling, which gives your clinician the pattern they need. Notice the triggers that repeat, often boredom, stress, alcohol, or a day of undereating. Avoid weighing yourself daily. These steps help, but they work best paired with a structured program.
