Bulimia nervosa (BN) is a dangerous eating disorder that affects people of all ages, but the condition can be challenging to spot in younger people.
Learning how to identify bulimia symptoms in teenagers can be a helpful way to recognize the issue early and guide people to the appropriate treatment as soon as possible.
It's difficult, if not impossible, to calculate the number of people who struggle with mental disorders like bulimia nervosa. However, statistics and studies can help compile a picture of who is impacted by BN and other eating disorders.
One look at the issue estimated that around 2% of teenagers in the United States struggle with BN.1,2 These figures only accounted for people who met all the Diagnostic and Statistical Manual (DSM) criteria for an official diagnosis.1
2% of teens in the U.S. struggle with bulimia nervosa.
Another examination on the subject found the average age of onset for bulimia nervosa to be 12.4 years, with a lifetime prevalence rate of 0.9%, meaning many children may develop the condition early on and continue to struggle with it into their teens.6
Yet, while it's challenging to track the number of teenage BN cases each year, it remains clear that early intervention and early treatment are crucial for recovery.
In general, younger patients present with less severe symptoms than adults, which can cause many to be initially diagnosed with 'other specified feeding or eating disorders' (OSFED) and make it more challenging to recognize bulimia nervosa in teenagers overall.4,5
Still, some studies show that as adolescents develop into adults, their bulimia nervosa symptoms tend to become more severe.6 In either case, identifying these signs earlier—and helping the person get help as soon as possible—is critical.
Bulimia nervosa revolves around ongoing cycles of binge eating and purging. While this can cause several health issues in nearly every organ system, the most outwardly noticeable symptom may be rapid weight changes or weight fluctuation.
Those who utilize specific purging methods may also present with different physical symptoms of bulimia nervosa. Teenagers who use self-induced vomiting may have more dental or gastrointestinal problems, develop calluses or cuts on their hands or knuckles, or have puffy cheeks caused by swollen salivary glands.8
It's also possible to utilize excessive exercise as a purging method, and these teens may show signs of exhaustion or injury. Misusing laxatives is another typical compensatory behavior, which can lead to issues like constipation, bloating, and abdominal pain.
Bulimia nervosa may manifest more subtly in teenagers, with less frequent binge-purge episodes or less severe weight fluctuations than adults. Adults with bulimia nervosa tend to have more severe or chronic medical complications, as the disorder has likely persisted for a longer period, which is why it’s essential to get treatment as early as possible.4
Behavioral symptoms of bulimia nervosa may stem from the disorder itself or attempts to hide disordered behavior. Some common behavioral signs of BN include:8
Disappearing after meals (usually to the bathroom, if self-induced vomiting)
Hoarding or hiding food
Social withdrawal or isolation
Avoiding meals or events related to food
Excessively exercising or making frequent trips to the gym
The teenage years are usually complex and marked by many changing behaviors, so it may be especially hard to notice these bulimia nervosa symptoms in teenagers.
Emotional symptoms of bulimia nervosa tend to be the hardest and most extreme for teenagers because they are still developing, maturing, and learning emotional regulation. It's not uncommon for teenagers to struggle with low self-esteem, and many emotional symptoms of BN and low self-esteem overlap.
Rapid and unpredictable mood swings, moderate to severe depression (persistent feelings of sadness, hopelessness, and worthlessness), and anxiety frequently occur in teens with bulimia nervosa. They may struggle with excessive worry, fear, or nervousness, primarily related to body image and weight.
Bulimia nervosa in adolescents and younger teens can sometimes be related to emotional regulation or an attempt at coping with stress. Symptoms may be less severe, with younger patients more likely to present at normal body weight and more likely to hide their behaviors from others.5
Older teens with bulimia nervosa may have more entrenched patterns of disordered eating and a greater focus on body image. Emotional symptoms of bulimia nervosa may be more severe, and older teens may, therefore, be more likely to engage in risky compensatory behaviors than adolescents.5
Early intervention for teens with bulimia nervosa
One of the biggest reasons it's important to understand the signs of BN in teenagers is to help them get appropriate treatment as quickly as possible. Early intervention has been tied to overall faster and more lasting recovery, so helping a teen reach out to a mental health professional can be a huge benefit.7
If you're concerned your teen or someone you know may have bulimia nervosa or another eating disorder, some tips may make it easier to talk to them about the situation.
Understand that your teenager may not be fully aware of what bulimia nervosa is or why it's a cause for concern. Gather resources and have them available when you approach them.
Maintain a loving, calm, and focused tone while talking. Try to remain as respectful and positive as possible to keep the conversation non-confrontational.
Encourage your teenager to seek help and support, and offer to assist them in finding appropriate resources and professionals to guide them through their recovery.
The benefits of early intervention and treatment for bulimia nervosa
Due to the bulimia nervosa prevalence and treatment challenges among teens, early intervention is crucial. Some additional benefits include:7
An improved speed of recovery: Research indicates that early identification and treatment can lead to faster recovery from bulimia.
Greater reduction in symptoms: Early intervention can help reduce the severity of symptoms to a greater extent than treatment initiated later in the course of the illness.
An increased likelihood of staying free of the illness: Initiating treatment early can improve the chances of achieving and maintaining a full recovery from bulimia nervosa.
Reduced long-term damage: Early intervention and the development of healthy eating habits can help minimize the long-term physical and psychological consequences associated with bulimia nervosa.

Disclaimer about "overeating": Within Health hesitatingly uses the word "overeating" because it is the term currently associated with this condition in society, however, we believe it inherently overlooks the various psychological aspects of this condition which are often interconnected with internalized diet culture, and a restrictive mindset about food. For the remainder of this piece, we will therefore be putting "overeating" in quotations to recognize that the diagnosis itself pathologizes behavior that is potentially hardwired and adaptive to a restrictive mindset.
Disclaimer about weight loss drugs: Within does not endorse the use of any weight loss drug or behavior and seeks to provide education on the insidious nature of diet culture. We understand the complex nature of disordered eating and eating disorders and strongly encourage anyone engaging in these behaviors to reach out for help as soon as possible. No statement should be taken as healthcare advice. All healthcare decisions should be made with your individual healthcare provider.
