Bulimia Nervosa.

Eating disorders are complex mental health conditions that can have severe physical and emotional consequences. Bulimia nervosa, commonly known as bulimia, is an eating disorder that causes binge eating followed by compensatory behaviors such as excessive exercise or self-induced vomiting. It’s possible to manage or overcome bulimia with therapy and, in some cases, medication. Let’s explore everything you should know about bulimia.

What is Bulimia Nervosa?

Bulimia Nervosa is an eating disorder characterized by cycles of binge eating followed by purging behaviors. These behaviors include purging and non-purging methods such as:

  • Misusing diuretics or laxatives
  • Fasting
  • Self-induced vomiting.
  • Excessive exercise.
  • Hiding food to binge and purge in private.

Bulimia is a severe condition that can significantly impact an individual’s physical and emotional well-being. It’s important to understand that this disorder can affect people of any gender, age, race, ethnicity, body type, or background. It’s not exclusive to any particular demographic; anyone can experience its effects.

Symptoms of Bulimia

Identifying bulimia nervosa can be challenging as those affected often go to great lengths to hide their behaviors.

Physical Signs:

  • Dental Issues: Frequent vomiting can lead to erosion of tooth enamel.
  • Gastrointestinal Problems: Issues like constipation and acid reflux can occur.
  • Electrolyte Imbalance: This can lead to abnormal heart rhythms and even heart failure.
  • Nutritional Deficiencies: Lack of essential nutrients can result in various health issues.

Emotional and Behavioral Signs:

  • Depression and Anxiety: These are common co-occurring conditions.
  • Low Self-Esteem: Constant preoccupation with body image can lead to a negative self-view.
  • Social Isolation: The secretive nature of the disorder can lead to withdrawal from friends and family.

Causes of Bulimia

Bulimia manifests more often in women than men, generally during their teenage years, but its exact causes are unknown. That said, bulimia is likely a combination of genetic factors, psychological factors, and learned behaviors from the surrounding culture.

Psychological Factors

Low self-esteem, body dissatisfaction, and perfectionism are some psychological risk factors.

Bulimia is closely associated with multiple mental illnesses, including self-harm, suicidal ideation, depression, anxiety, borderline personality disorder, substance abuse, and obsessive-compulsive disorder. It’s unclear whether these mental illnesses cause bulimia, bulimia causes these illnesses, or a more complex relationship is at play.

Biological Factors

While the exact cause is unknown, genetic predisposition and neurotransmitter imbalances are thought to play a role in the development of bulimia nervosa.

People with bulimia may come from relatives who previously had bulimia or other eating disorders. Research suggests eating disorders are linked to serotonin and other chemicals in the brain that play a role in appetite regulation and impulse control.

Cultural Factors

Cultural views on appearance and body weight could negatively affect how a person views their body image and increase the risk of bulimia in these individuals.

Media portrayal of “ideal” body types can contribute to the development of bulimia. The pressure to conform to a societal standard of appearance may increase the risk of bulimia.

Treatment for Bulimia

Like many other eating disorders, there’s no single treatment course for bulimia. In most cases, it’s a combination of psychotherapy, medication, and peer support.


Psychotherapy, or talk therapy, is one of the most effective treatments for bulimia. The most commonly used for treating bulimia include:

Cognitive behavioral therapy (CBT)

CBT focuses on helping change thought and behavioral patterns to promote healthier habits around food. It’s been shown to have good long-term results in bulimia and other eating disorders.

Interpersonal therapy (IPT)

Often lasts around 12 weeks and focuses on your relationship with the people around you and how they influence your mental health. It’s very effective for depression and other mental illnesses that may co-occur with bulimia.

Family-based therapy

Family therapy can be helpful if your condition affects your relatives or your family setting contributes to bulimia (like a parent pressuring their child to lose weight or look a certain way). It helps the family understand bulimia and how to provide during recovery.


In some cases, mental health professionals may recommend medication to treat the mental illness aspect of bulimia. Fluoxetine, known by its brand name Prozac, is a selective serotonin reuptake inhibitor (SSRI) that works as an antidepressant. However, medication alone is generally not as effective as when combined with psychotherapy.


Early intervention is crucial for effective treatment. Awareness of the warning signs and seeking help can prevent the condition from worsening. Furthermore, educational programs can also help debunk societal myths about body image.

Outlook for Bulimia

Managing bulimia can be a lifelong process. With appropriate treatment, about 50% of people fully recover. However, some may experience relapses and require ongoing treatment. Left untreated, the disorder can lead to severe complications.

Living With Bulimia Nervosa

Bulimia nervosa affects between 1% and 2% of people during any given year. Living with bulimia nervosa is a daily struggle that affects not only the individual but also their loved ones. Support groups and ongoing therapy can provide invaluable help.

Managing bulimia nervosa is an ongoing process that may require a long-term commitment to therapy and medication. Regular medical check-ups, nutritional counseling, and support from loved ones are essential for long-term recovery. Mindfulness techniques and stress management can also be beneficial.

It’s essential to remember that there is no gold standard for how you should look. Your body develops and changes over time; it is never a moral failing to be above a certain weight.
