Common Warning Signs of Bulimia Nervosa in Adolescents: Quick Reference Guide for Parents or Caregivers 

By Lee Neagle MA, LPC| 3 Min Read | April 4, 2024

Bulimia nervosa is a serious eating disorder that can have severe physical and psychological consequences if left untreated. It can be challenging to recognize the signs of certain mental health disorders, such as bulimia, especially during the tumultuous adolescent years.   

In this blog post, we’ll discuss some common warning signs of bulimia nervosa in adolescents, empowering parents to intervene early with effective treatment. 

  • Significant Changes in Eating Behaviors: One of the most apparent warning signs of bulimia nervosa is a drastic change in eating habits. Adolescents with bulimia may engage in episodes of binge eating, consuming large amounts of food in a short period of time, and sometimes they may experience a lack of control during these episodes. Following binge eating, individuals with bulimia may engage in compensatory behaviors, such as purging through self-induced vomiting, excessive exercise, or the misuse of laxatives or diuretics. 
  • Preoccupation with Body Image: Adolescents with bulimia nervosa often have a dissatisfaction with their body shape and size. They may excessively scrutinize themselves in the mirror, express negative comments about their appearance, and/or regularly compare themselves to others.  
  • Physical Symptoms: In addition to behavioral changes and preoccupation with body image, there are several physical signs and symptoms that parents should be aware of. These may include frequent fluctuations in weight, swollen glands in the neck or jaw area (due to repeated vomiting), dental problems (such as enamel erosion or tooth decay), gastrointestinal issues, dehydration, and fatigue. 
  • Emotional Distress and Secrecy: Bulimia nervosa can take a toll on an adolescent’s emotional well-being, leading to frequent mood swings and emotional distress. Parents may notice their child becoming increasingly withdrawn, anxious, or depressed. Adolescents with bulimia may also exhibit secrecy regarding their eating habits and avoid situations that involve food. 
  • Social Avoidance: Adolescents with bulimia nervosa may isolate themselves and withdraw from activities that involve food. They may make excuses to avoid meals with family or friends, preferring to eat alone where their behaviors can go unnoticed. This social withdrawal can further isolate them from supportive relationships, exacerbating their feelings of shame and guilt associated with their eating disorder. 

Recognizing the warning signs of bulimia nervosa in adolescents is crucial for early intervention and treatment. With timely intervention and support, adolescents with bulimia nervosa can receive the necessary treatment to address their physical and emotional needs, paving the way for recovery and improved overall well-being.
