Binge-eating disorder

Binge-eating disorder is a serious eating disorder in which you frequently consume unusually large amounts of food. Almost everyone overeats on occasion, such as having seconds or thirds of a holiday meal. But for some people, overeating crosses the line to binge-eating disorder and it becomes a regular occurrence, usually done in secret.

When you have binge-eating disorder, you may be deeply embarrassed about gorging and vow to stop. But you feel such a compulsion that you can't resist the urges and continue binge eating. If you have binge-eating disorder, treatment can help.

Symptoms:

You may have no obvious physical signs or symptoms when you have binge-eating disorder. You may be overweight or obese, or you may be at a normal weight. However, you likely have numerous behavioral and emotional signs and symptoms, such as:
  • Eating unusually large amounts of food
  • Eating even when you're full or not hungry
  • Eating rapidly during binge episodes
  • Eating until you're uncomfortably full
  • Frequently eating alone
  • Feeling that your eating behavior is out of control
  • Feeling depressed, disgusted, ashamed, guilty or upset about your eating
  • Experiencing depression and anxiety
  • Feeling isolated and having difficulty talking about your feelings
  • Frequently dieting, possibly without weight loss
  • Losing and gaining weight repeatedly, also called yo-yo dieting
After a binge, you may try to diet or eat normal meals. But restricting your eating may simply lead to more binge eating, creating a vicious cycle.

When to see a doctor
If you have any symptoms of binge-eating disorder, seek medical help as soon as possible. Binge-eating disorder usually doesn't get better by itself, and it may get worse if left untreated.

Talk to your primary care doctor or a mental health provider about your binge-eating symptoms and feelings. If you're reluctant to seek treatment, talk to someone you trust about what you're going through. A friend, loved one, teacher or faith leader can help you take the first steps to successful treatment of binge-eating disorder.

Helping a loved one who has symptoms
A person with binge-eating disorder can become an expert at hiding behavior, making it hard for others to detect the problem. If you have a loved one you think may have symptoms of binge-eating disorder, have an open and honest discussion about your concerns. You can offer encouragement and support and help your loved one find a qualified doctor or mental health provider and make an appointment. You may even offer to go along.

Causes:

 The causes of binge-eating disorder are unknown. But family history, biological factors, long-term dieting and psychological issues increase your risk.


Complications:

You may develop psychological and physical problems related to binge eating. Some of these complications arise from being overweight due to frequent bingeing. Other complications may occur because of unhealthy yo-yo eating habits — bingeing followed by harsh dieting. In addition, food consumed during a binge is often high in fat and low in protein and other nutrients, which could lead to health problems.

Complications that may be caused by, or linked with, binge-eating disorder include:
  • Depression
  • Suicidal thoughts
  • Insomnia
  • Obesity
  • High blood pressure
  • Type 2 diabetes
  • High cholesterol
  • Gallbladder disease and other digestive problems
  • Heart disease
  • Some types of cancer
  • Joint pain
  • Muscle pain
  • Headache
  • Menstrual problems
Treatments and drugs:

The goals for treatment of binge-eating disorder are to reduce eating binges, to improve your emotional well-being and, when necessary, to lose weight. Because binge eating is so entwined with shame, poor self-image, self-disgust and other negative emotions, treatment needs to address these and other psychological issues. By getting help for binge eating, you can learn how to properly lose weight and keep it off.

There are four main types of treatment for binge-eating disorder.

Psychotherapy
Psychotherapy, whether in individual or group sessions, can help teach you how to exchange unhealthy habits for healthy ones and reduce bingeing episodes. Examples of psychotherapy include:
  • Cognitive behavioral therapy (CBT). CBT may help you cope better with issues that can trigger binge-eating episodes, such as negative feelings about your body or a depressed mood. It may also give you a better sense of control over your behavior and eating patterns. If you're overweight, you may need weight-loss counseling in addition to CBT.
  • Interpersonal psychotherapy. Interpersonal psychotherapy focuses on your current relationships with other people. The goal is to improve your interpersonal skills — how you relate to others, including family, friends and colleagues. This may help reduce binge eating that's triggered by poor relationships and unhealthy communication skills.
  • Dialectical behavior therapy. This form of therapy can help you learn behavioral skills to help you tolerate stress, regulate your emotions and improve your relationships with others, all of which can reduce the desire to binge eat.
Medications
There's no medication specifically designed to treat binge-eating disorder. But, several types of medication may help reduce symptoms, especially when combined with psychotherapy. Examples include:
  • Antidepressants. Antidepressants known as selective serotonin reuptake inhibitors (SSRIs) and tricyclic antidepressants (TCAs) may be helpful. It's not clear how these can reduce binge eating, but it may relate to how they affect certain brain chemicals associated with mood.
  • The anticonvulsant topiramate (Topamax). Normally used to control seizures, topiramate has also been found to reduce binge-eating episodes. However, potentially it can cause serious side effects, so discuss these risks with your doctor.
Behavioral weight-loss programs
Many people with binge-eating disorder have a long history of failed attempts to lose weight on their own. However, weight-loss programs typically aren't recommended until the binge-eating disorder is treated because very low calorie diets may trigger more binge-eating episodes.

When appropriate, weight-loss programs are generally done under medical supervision to ensure that your nutritional requirements are met. Weight-loss programs that address binge triggers can be especially helpful when you're also getting cognitive behavioral therapy.

Self-help strategies
Some people with binge-eating disorder find self-help books, videos, Internet programs or support groups effective. Some eating disorder programs offer self-help manuals that you can use on your own or with guidance from mental health experts. However, you still may need professional treatment with psychotherapy or medications.
