Bulimia nervosa stands out as one of the most widespread eating disorders, accounting for 19% of all diagnosed cases within this category.
Determining whether someone has bulimia solely based on their appearance is highly unlikely, as the secretive nature of this eating disorder makes it challenging to detect.
However, with proper education and access to appropriate treatment, the chances of achieving a complete recovery from bulimia are significantly promising.
What is bulimia?
Bulimia nervosa, formally recognised as bulimia, manifests as an eating disorder marked by repetitive episodes of excessive eating, accompanied by compensatory actions aimed at averting weight gain.
Those with bulimia often consume large amounts of food in a short period, feeling a lack of control during these episodes. Subsequently, they engage in behaviours such as self-induced vomiting, excessive exercise, fasting, or misuse of laxatives to counteract the effects of overeating.
The diagnostic criteria in the DSM-V for bulimia?
According to the DSM-5, the diagnostic criteria for bulimia nervosa include the following:
- Recurrent episodes of binge eating, characterised by both of the following:
- Eating, in a discrete period of time (e.g., within any 2 hours), an amount of food that is larger than most people would eat during a similar period and under similar circumstances.
- A sense of lack of control over eating during the episode (e.g., a feeling that one cannot stop eating or control what or how much one is eating).Repetitive inappropriate compensatory actions to avert weight gain, such as self-induced vomiting, improper use of laxatives, diuretics, or other medications, periods of fasting, or excessive exercise.
- The binge eating and inappropriate compensatory behaviours both occur, on average, at least once a week for 3 months.
- Self-evaluation is unduly influenced by body shape and weight.
- The disturbance does not occur exclusively during episodes of anorexia nervosa.

Are there different types of bulimia?
While there are general diagnostic criteria for bulimia nervosa, some people may experience the disorder in various ways, leading to the identification of different subtypes or presentations. That said, some clinicians and researchers may use terms like ‘purging’ and ‘nonpurging’ to describe different presentations of bulimia, although it’s important to note that the DSM-V doesn’t formally recognise these subtypes.
- Purging type: People with this subtype regularly engage in self-induced vomiting or misuse of laxatives, diuretics, or enemas as a way to compensate for the calories consumed during binge eating episodes.
- Non-purging type: People with this subtype use other inappropriate compensatory behaviours to prevent weight gain, such as excessive exercise or fasting, but do not regularly engage in vomiting or the misuse of laxatives.
The different levels of bulimia
It’s important to note that the severity of bulimia is often assessed based on the frequency of binge eating and inappropriate compensatory behaviours:
- Mild: 1-3 episodes per week
- Moderate: 4-7 episodes per week
- Severe: 8-13 episodes per week
- Extreme: 14 or more episodes per week

These severity levels help guide treatment planning and interventions.
What are the causes of bulimia?
The causes of bulimia are complex and multifaceted, involving a combination of genetic, psychological, biological and environmental factors. Some of the key factors include:
Psychological factors
Psychological factors are significant contributors to bulimia. Low self-esteem, body dissatisfaction and a distorted body image can contribute to the development of the disorder.
It’s also worth noting that those with an eating disorder scored higher on measures of personality disorders, impulsivity, obsessive-compulsive traits and perfectionism compared to those with no eating disorders.
Genetic factors
There is evidence that genetics play a role in the development of eating disorders, including bulimia. Studies have shown that people who have a relative with bulimia are at an elevated risk for developing an eating disorder.
Heritability also plays a factor too. Some studies estimated that the heritability rate of bulimia is estimated to be up to 62%, a shockingly high number.
Traumatic experiences
Individuals who have experienced trauma, such as physical, emotional, or sexual abuse, may be at a higher risk of developing bulimia. Research showed that 25.5% of bulimia patients fulfilled the study definition for Post Traumatic Stress Syndrome (PTSD).
The finding suggests a potential association between bulimia and PTSD, highlighting a co-occurrence or interplay between eating disorders and trauma.
Environmental factors
Societal and cultural pressures to conform to certain body standards and ideals can contribute to the development of bulimia. Media images, societal expectations and peer pressure may shape individuals’ perceptions of their bodies.
In a 2023 study of participants aged 14-25, 42% exhibited probable eating disorders and 41.7% displayed signs of social media addiction. The findings imply a possible connection between social media use and body image concerns, with societal pressures and unrealistic beauty standards on these platforms playing a role.

Bulimia recovery is more than achievable
While it poses significant risks to physical and mental health, it is encouraging to note that many of those who seek help for bulimia are able to make a full recovery.
The journey to recovery from bulimia often involves a combination of medical, psychological and nutritional interventions. Seeking professional help from healthcare providers, including therapists, nutritionists and medical professionals, is crucial for developing a comprehensive treatment plan.
A closer look at the positive stats
Early intervention and treatment play pivotal roles in bolstering the chances of overcoming bulimia. Studies reveal a promising 55% recovery rate after just five years of dedicated intervention. The trajectory becomes even more encouraging, with half of individuals achieving full recovery within a decade.
Emphasising the profound impact of timely support, the mortality rate remains impressively low at 0-3% when interventions are initiated promptly. This underscores the significance of early detection and intervention in creating a positive path toward sustained recovery, fostering resilience and enabling individuals to reclaim their lives from the grips of bulimia with a high probability of success.

Spotting the signs of bulimia in a loved one
Identifying the signs of bulimia in a loved one can be challenging, as those with this disorder often go to great lengths to hide their behaviours.
Here are some signs that may indicate someone is struggling with bulimia:
- Fluctuations in weight: While not everyone with bulimia will experience extreme weight changes, noticeable fluctuations in weight (both up and down) could be a sign. This can result from the cycles of binge eating and purging.
- Frequent trips to the bathroom: Those with bulimia often purge to eliminate the calories consumed during a binge. Frequent trips to the bathroom, especially after meals, may indicate purging behaviours such as vomiting or laxative use.
- Evidence of binge eating: Discovering large amounts of food wrappers or empty containers, particularly high-calorie or sweet foods, may suggest episodes of binge eating.
- Physical signs: Bulimia can have physical manifestations such as swollen glands, tooth decay and calloused knuckles due to induced vomiting. These signs may be subtle but can be indicative of purging.
- Social withdrawal: People with bulimia may become socially withdrawn, avoiding social events that involve food. This can be an attempt to conceal their disordered eating habits and maintain secrecy.
- Obsessive concern with body image: A preoccupation with body weight, shape and appearance can be a sign of bulimia. Constantly talking about dieting or expressing dissatisfaction with one’s body may indicate an unhealthy relationship with food.
What are the next steps?
If you or someone you care about currently has bulimia, taking proactive steps is crucial. Begin by reaching out to a healthcare or mental health professional to initiate a discussion about potential symptoms, binge-purge patterns and related emotional challenges.
A thorough assessment will shape a personalised treatment approach, which may include a range of therapies and medical assistance.
Remember that timely intervention plays a pivotal role in effectively managing bulimia, meaning that the quicker help is sought, the quicker the recovery phase begins. We understand that reaching out for help could be daunting, but doing this marks a significant stride toward achieving a healthier and more harmonious life.
