Bulimia Nervosa
What is Bulimia Nervosa?
Bulimia nervosa is a serious eating disorder characterized by cycles of binge eating followed by compensatory behaviors to prevent weight gain, such as self-induced vomiting, excessive exercise, fasting, or misuse of laxatives and diuretics. During a binge episode, individuals consume large amounts of food in a short period, often feeling out of control. Afterward, intense guilt, shame, or fear of weight gain leads to purging or other compensatory actions. Unlike anorexia, individuals with bulimia may maintain a normal or fluctuating weight, making the disorder harder to detect. If left untreated, bulimia can cause severe physical and emotional health complications, including electrolyte imbalances, heart issues, digestive problems, and long-term damage to the esophagus and teeth.
If you or someone you know is struggling with bulimia, professional treatment can help break the binge-purge cycle and restore a healthy relationship with food. Therapy, nutritional counseling, and medical support are essential to address both the physical and psychological aspects of the disorder. Cognitive-behavioral therapy (CBT), dialectical behavior therapy (DBT), and medication options can help individuals manage emotional triggers and develop healthier coping strategies. Recovery is possible, and seeking help is the first step toward healing.
Types of Bulimia Nervosa
Purging Type
The purging type of bulimia nervosa involves regular use of behaviors such as self-induced vomiting, laxative abuse, diuretic misuse, or enemas after binge eating. These methods are used in an attempt to rid the body of calories consumed during a binge. Over time, purging can lead to severe medical complications, including tooth enamel erosion, acid reflux, throat damage, and life-threatening electrolyte imbalances that increase the risk of heart problems.
Non-Purging Type
The non-purging type of bulimia involves compensatory behaviors that do not include purging, such as excessive exercise, fasting, or extreme dieting to counteract binge episodes. While these behaviors may seem less harmful than purging, they can still lead to serious health issues, including malnutrition, dehydration, and long-term metabolic disruptions. This subtype is often harder to recognize, as behaviors like excessive exercise can be socially acceptable or even praised.

If you recognize these symptoms in yourself or a loved one, seeking professional support can be life-changing. Recovery is possible with the right treatment and support system.
What Causes Bulimia Nervosa?
Bulimia nervosa is a multifaceted disorder influenced by genetic, psychological, and environmental factors. While the exact cause varies from person to person, common contributing factors include:
Psychological Factors: Anxiety, OCD, and Perfectionism
Many individuals with bulimia struggle with anxiety disorders, obsessive-compulsive disorder (OCD), or perfectionism. These traits can contribute to rigid food rules, all-or-nothing thinking, and intense fear of failure regarding weight and body image. People with OCD tendencies may develop strict rituals around eating, purging, or exercising, which can reinforce the binge-purge cycle. The disorder often provides a sense of control over emotions, but this cycle ultimately leads to increased distress and compulsive behaviors.
Neurodevelopmental Factors: ADHD and Impulsivity
Research has shown a strong link between bulimia nervosa and attention-deficit/hyperactivity disorder (ADHD). Individuals with ADHD often struggle with impulsivity and difficulty regulating behaviors, making them more prone to binge eating episodes. Since bulimia involves acting on urges quickly, the impulsive nature of ADHD can make it harder to stop the binge-purge cycle. Additionally, ADHD-related dopamine imbalances may contribute to seeking out highly palatable foods as a way to regulate emotions or stimulation levels.
Emotional Dysregulation and Trauma
Bulimia often develops as a coping mechanism for emotional distress, trauma, or unresolved psychological pain. Many individuals with bulimia have a history of emotional, physical, or sexual trauma, which can contribute to disordered eating as a way to regain control or numb painful feelings. The binge-purge cycle can temporarily relieve anxiety, sadness, or feelings of emptiness, but over time, it reinforces guilt and shame, leading to further emotional distress.
Sociocultural Pressures and Body Image Concerns
Societal emphasis on thinness, diet culture, and unrealistic beauty standards can fuel the development of bulimia. People in appearance-focused environments (such as athletes, dancers, models, or influencers) may feel extreme pressure to maintain a certain body size, increasing the likelihood of engaging in disordered eating behaviors. Exposure to social media, weight-related teasing, or family pressure to diet can also reinforce unhealthy attitudes toward food and body image.
