What is binge-eating disorder?

Binge-eating disorder (BED) is both a type of eating disorder and a mental health disorder.

Binge eating is different from overeating. Overeating is something that most people do sometimes, such as in social settings.

People with binge-eating disorder repeatedly act on an urge to eat large quantities of food in a short period of time, often in private. The foods most often eaten are highly processed foods such as breads, biscuits, chips and sweets.

What causes binge-eating disorder?

There are many possible causes of binge-eating disorder. Like other mental health conditions, binge-eating disorder can arise from childhood abuse or trauma. Some people have no obvious reason for having binge-eating disorder.

Some things may place you at higher risk of developing a binge-eating disorder, such as:

• anxiety, depression or low self-esteem
• other mental health or developmental diagnoses such as autism spectrum disorder
• drug or alcohol use
• dieting or food insecurity
• unmet social, spiritual, emotional or physical needs
• a family history of eating disorders

What are the symptoms of binge-eating disorder?

People with binge-eating disorder might feel:

• out of control when they eat
• the need to hoard food

They may eat:

• large amounts of food in a short period of time, often sweet and savoury carbohydrates
• rapidly
• in secret
• when they are not hungry
• until after they feel full
• as a way to cope with emotional distress

They might binge eat once or more each week, over a few months. This might evolve to become more frequent, e.g. daily.

People with binge-eating disorder are distressed by their eating behaviour and may feel:

• ashamed
• guilty after an eating binge
• embarrassed by their actions

This can impact their life. They may withdraw from their usual activities and from family and friends.

People with binge-eating disorder can also experience physical symptoms, such as:

• abdominal (tummy) pain
• bloating and other gut issues
• fatigue
• difficulty concentrating
• headaches
• sleep disturbance
• heartburn

Binge-eating disorder is similar to bulimia nervosa. People with these disorders are often concerned about body image and consume large amounts of food.

However, people with binge-eating disorder do not use extreme weight loss measures every time they binge, such as:

• forced vomiting
• laxatives
• excessive exercise

As a result, their weight may fluctuate, or they might be overweight or obese.

When should I see a doctor?

If you think you have binge-eating disorder, it is important to see a doctor. They can refer you to a specialist in eating disorders such as a:

• psychologist or psychiatrist
• dietitian

Stigma around mental health and body image can make it difficult to seek help. Remember that you are not alone — binge-eating disorder makes up almost half of all eating disorder cases in Australia.

How is binge-eating disorder treated?

The best treatment for binge-eating disorder is psychological therapy and dietary guidance.

Psychological therapy such as cognitive behavioural therapy aims to:

• address the underlying cause of your binge-eating disorder
• help you to manage and overcome your binge-eating disorder

Dietary therapy aims to help you build a healthy, regular eating pattern by:

• reducing your binge eating
• challenging your food beliefs
• developing your confidence in eating

Exercise and managing stress are also both important in your recovery.

You can also talk to your doctor about medication options that may benefit you.

Can binge-eating disorder be prevented?

Eating regular, satisfying meals can help to prevent binge-eating disorder.

Recognising the signs of things that may cause binge-eating disorder can also help prevent it.

Complications of binge-eating disorder

If unmanaged, binge-eating disorder can lead to other problems such as:

• obesity
