Bulimia Nervosa
Overview
Bulimia nervosa (sometimes referred to as bulimia or BN) is an eating disorder that has the potential to be life-threatening. An individual with bulimia may feel obsessed with their weight and with food. They often seek to control their weight by an eating pattern that includes binging and purging.
Binging is the act of eating large amounts of food in a short period of time (typically within two hours). Purging is the act of getting rid of this food through forced vomiting or the use of laxatives, diuretics, or other medications.
People who experience bulimia nervosa may also seek to control their body through periods of fasting or excessive exercise. Bulimia nervosa may go unnoticed for many years, as those who have it often have a typical weight or only slightly above-average weight.
Symptoms
According to Johns Hopkins Medicine, bulimia can present itself in two ways: purging type and non-purging type. The symptoms a person experiences typically depend on which type of bulimia nervosa they have. Purging is when the individual uses self-induced vomiting, laxatives, diuretics, or enemas to clear out the digestive system. Non-purging individuals typically use other means of controlling calorie levels, such as excessive exercise, weight loss pills, or fasting.
Bulimia nervosa’s symptoms can be divided into physiological and psychological/behavioral symptoms. The psychological and behavioral symptoms of bulimia nervosa may include:
- Signs of purging behaviors, such as frequent bathroom visits after meals, evidence of vomiting, or boxes of laxatives or diuretics noticed around the house
- Disappearance of large amounts of food at a time, food wrappers hidden around the house, or any other indicator of someone eating large amounts of food
- Behaviors and beliefs that indicate that weight loss, control of food, and dieting are becoming an obsession in the individual’s life
- A tendency to be overly focused on diet fads
- Reluctance to eat in public or with other people
- Reliance on breath mints, gum, or mouthwash
- An excessive, rigid exercise routine
- Presence of food rituals
- A tendency of a person to hide their body with baggy clothing
- A preoccupation with body image and an intense fear of gaining weight
- Depression, anxiety, and/or social withdrawal
- Risky behaviors, such as drug or alcohol use
Physiological symptoms of bulimia nervosa can include:
- Fatigue and decreased energy
- Dental problems due to the erosion of enamel caused by frequent vomiting
- Continually inflamed or sore throat
- Heart arrhythmia
- Throat and stomach ulcers
- Dry and brittle nails
- Poor wound healing
- Irregular menstrual periods
- Swollen jawline or cheeks
- Fainting
- Bloodshot eyes
- Calluses or scars on knuckles (from forced vomiting)
According to the American Society for Nutrition, eating disorders (like anorexia nervosa1 and bulimia nervosa) have a high risk of death—second only to addiction to opioids. The medical complications from starvation can be extremely dangerous, and yet difficult to detect until it’s too late. A secondary cause of death with eating disorders tends to be suicide.* It is highly recommended that you get help if you suspect you have an eating disorder like bulimia nervosa or if you suspect it in a loved one.
Causes
There is no single known cause of bulimia nervosa, but researchers believe that bulimia can stem from a combination of genetics and learned behaviors. Those who have family members with bulimia nervosa may be at greater risk for developing the disorder themselves. Bulimia nervosa tends to show up most often in teenage girls but can affect people of all genders.
Risk factors for bulimia nervosa
There are some risk factors that may indicate a greater chance of experiencing bulimia nervosa, including the following:
- Age and gender (teenage girls—although people of all genders can have bulimia, it tends to be more prevalent in women)
- Low self-image or self-worth
- Other mental disorders, such as depression or anxiety
- Substance use disorder
- Excess weight as a child or teen
- Excessive stress or boredom
- Family members with eating disorders
Treatments
Treatment for bulimia nervosa may involve a combination of therapeutic approaches. A strong inter-professional approach with medical and mental health professionals can be most effective for long-term success in treating bulimia nervosa and other eating disorders.
Therapy for bulimia nervosa
Psychotherapy, both individual and family, is often used to address self-esteem and body-image concerns, as well as build better eating habits and offer stress management and coping skills. Cognitive behavioral therapy (CBT),2 a type of therapy that can be effective at replacing negative thought and behavior patterns with more positive ones, is most commonly used in the treatment of bulimia nervosa and other types of mental illness.
Mental health professionals who specialize in a form of CBT focused on the treatment of eating disorders can be the most effective at ensuring that an individual with bulimia nervosa doesn’t relapse to former behaviors.
According to the Mayo Clinic, therapy for bulimia may also include interpersonal therapy to improve relationships and family-based therapy to help parents and the whole family address problems related to bulimia nervosa.
Medication
Medication is not generally used in the treatment of eating disorders like bulimia nervosa. However, in some cases, antidepressant medications may be prescribed to alleviate symptoms of bulimia nervosa. The only medication currently approved for bulimia by the U.S. Food and Drug Administration (FDA) is fluoxetine (Prozac). Do not start, stop, or change a medication for bulimia nervosa without consulting with a healthcare professional.
Other bulimia treatment options
Any severe physical symptoms of bulimia nervosa may be treated by a medical professional in a hospital or outpatient setting. These include symptoms like electrolyte imbalance, ulcers, dental problems, or any other challenges that may have been caused by purging behaviors.
A therapist may work with family members to educate them on bulimia nervosa and appropriate interactions with food and exercise. A strong support system can be helpful for those who experience eating disorders like bulimia nervosa.
Self-care
As a part of the therapeutic process, a bulimia therapist may work with individuals on learning and implementing self-care practices to help manage stress and build self-esteem. This can include mindfulness or relaxation techniques like deep breathing or meditation, positive self-talk, social support systems, and healthy lifestyle habits that are not centered on food.
Resources
Cognitive-behavioral therapy (CBT) is considered the first-line therapeutic treatment for bulimia nervosa. CBT is designed to replace negative patterns of thought and behavior. Licensed therapists who practice CBT may be able to help you identify the source of negative thoughts and beliefs and guide you toward a more positive body image and better mental health.
For those who may have difficulty finding a therapist in their geographical area, online therapy offers a variety of choices. With an online therapy platform like BetterHelp, you can fill out a simple questionnaire and be matched with a licensed therapist who meets your needs.

Research
Research shows that cognitive behavioral therapy specialized on the treatment of eating disorders is the most effective form of therapy, when compared to other psychological interventions.
A recent study has suggested that there is a brain response that reinforces behaviors in binge eating and bulimia nervosa. Researchers believe that continued study into the neurobiological aspect of eating disorders can help in discovering more effective avenues of treatment.
Statistics
40% to 60% of individuals with bulimia achieve remission after therapy
Here are more key statistics on bulimia nervosa, anorexia, and binge eating disorder:
- The standard onset of bulimia nervosa (as well as anorexia nervosa) is between 12 and 25 years old.
- The one-year prevalence of bulimia nervosa is 0.32% for females and 0.05% for males.
- Around 94.5% of individuals with bulimia met criteria for at least one other core DSM-IV mental health disorder in the National Comorbidity Survey Replication.
