Definition, Symptoms, and Diagnosis

What is bulimia?

Bulimia nervosa involves episodes of eating large quantities of food (binging) and then purging through compensatory behaviors such as self-induced vomiting, inappropriate use of laxatives, fasting, and/or over-exercising.

How common is bulimia nervosa?

The lifetime prevalence of bulimia nervosa is 1.5% in women and 0.5% in men in the U.S. This means nearly 5 million women and 1.5 million men are affected by bulimia at some point in their lives.

What are the signs and symptoms of bulimia nervosa?

The following are some signs that indicate an individual may be struggling with bulimia:

  • Suddenly leaving at the end of a meal to use the bathroom or using it several times throughout the meal

  • Eating large quantities of food but not gaining the expected weight

  • Loss of tooth enamel from excessive vomiting

  • Callous or sores on knuckles from self-induced vomiting

  • Discovering vomit in unexpected places such as a shower or kitchen sink or bags of vomit in unexpected places

In addition, social isolation, withdrawal, and depression often accompany bulimia nervosa. 

How do you diagnose bulimia?

According to the DSM-V (Diagnostics and Statistics Manual), a manual that mental health professionals use to diagnose mental health conditions, the compensatory behavior must occur at least once a week for at least 3 months. These behaviors cannot be part of episodes of anorexia (Pocket DSM 173). Also, individuals must feel out of control during binge episodes. Additionally, low self-worth occurs due to the patient’s evaluation of their body shape, image, and weight.

What are medical complications of bulimia?

Chronic, self-induced vomiting can cause various symptoms within the digestive tract, mouth, and other parts of the body. These include but are not limited to:

  • Tooth decay

  • Ruptured esophagus

  • Continual sore throat

  • Stomach pain

  • Hair loss

  • Internal bleeding from vomiting

  • Swollen salivary glands (sialadenosis)

  • Acid reflux

  • Electrolyte abnormalities

  • Dehydration

Treatment for bulimia

What is the best treatment for bulimia?

Treatment for bulimia includes individual talk therapy, group therapy, family therapy, and nutritional counseling and education. In some cases medication is prescribed for mood and anxiety management. Research supports that cognitive behavioral therapy (CBT) can be an effective approach to eating disorder treatment, especially bulimia nervosa. Therapists may also use treatment approaches such as Acceptance and Commitment Therapy (ACT), Gestalt therapy, mindfulness approaches, and motivational interviewing. Treatment focuses on helping the individual to communicate their feelings, increase their sense of self-worth, identify negative patterns of thinking, and change their negative behaviors and self-harming behaviors all while helping to reduce their sense of shame.

Help a friend with bulimia

How can you help someone with bulimia?

Helping someone with bulimia nervosa involves being compassionate and understanding, even if you may not be able to fully understand what the individual is experiencing. Let the person know that you are there to listen and that you won’t judge them. Avoid making comments about what they eat or how. Avoid advising; rather, think more about listening and validating feelings. Researching the disorder to understand it better can be helpful, too. Ask if they are in treatment and what you can do as their friend or loved one to help support their treatment.

Here are some things to keep in mind when helping someone with bulimia nervosa:


  • Do be empathetic and express your love and support.

  • Do be honest about your own struggles to understand.

  • Do recognize there is no a quick and easy solution or cure.

  • Do listen and validate their feelings.

  • Do be patient and at the same time know your own limits.


  • Don’t try to be a therapist.

  • Don’t tell them to just eat something and to stop obsessing.

  • Don’t use shame or guilt to convince them to eat or change their behavior.

  • Don’t gossip to other people about what they are going through.

  • Don’t make critical or mean comments about their eating.
