Eating disorders often affect most adolescents and young adults. These conditions can severely impact a teen’s mental, physical, and social well-being.
Eating disorders aren’t always easy to identify; in fact, there are a number of hidden eating disorders affecting teens. Most teens with these conditions often succeed in “hiding” their struggles. Some of these conditions may also not have obvious indications. You may miss signs of:
Binge eating
Hidden snacks
Induced vomiting
Post-meal bathroom trips
Eating disorders can advance quickly and become life-threatening. There’s a connection between these conditions with kidney, liver, and heart diseases. Discovering the subtle signs soon can help you prevent the development of possibly fatal or life-changing illnesses and give your child a chance at a healthier life.
In this article, we will discuss how to identify hidden eating disorders affecting teens. This information will help you catch early signs and take the next steps to find help for your son or daughter.

Subtle Signs of Hidden Eating Disorders in Teens
Behavioral Changes
Teens may develop increased secrecy around their eating due to insecurities about their eating habits. You may notice that they:
Prefer to eat in private
Disappear soon after meals
Hide food in their bedrooms
Making frequent excuses to skip meals
Your child may also avoid social situations that involve food due to their phobia of eating in groups. This fear can arise from assumptions of someone noticing a change in their eating habits or appearance.
Teens with conditions such as anorexia nervosa may develop an obsession with calorie counting or “healthy eating” due to their fear of gaining weight. Teens with bulimia may further self-induce vomiting when they exceed their calorie limit.
Emotional Indicators
Eating disorders in teens can co-occur with mood disorders. You may also notice that your child is more irritable and withdrawn from family and friends. These emotional changes can result from sensitivity to their eating behavior, self-criticism, or the fear of being criticized by others.
Changes in a teen’s body often affect how they perceive themselves. They may experience increased teen anxiety as a result of insecurities about their changing bodies. So, they may regard their desire for a new appearance as a standard for perfectionism and self-worth. As a way to cope with their low self-esteem or perfectionism, they may turn to unhealthy habits that become eating disorders.
Physical Symptoms
You may have noticed that your son or daughter has low concentration or unexplained fatigue. They may fast, diet, or exercise excessively to lose or avoid gaining weight. They may also purge or self-induce vomiting after binge eating or a high-calorie intake. These actions can affect their concentration and cause fatigue.
Your child’s weight instability can also be an indication of an eating disorder. Teens who binge eat may gain weight due to rapid high-calorie intake. But when they induce vomiting, they may lose some weight initially before a rebound effect of weight gain occurs.
Your teen may experience gastrointestinal issues due to fasting in their attempt to control weight gain. Frequent complaints about constipation or feeling bloated can also result from starvation or purging.
Factors Contributing to Hidden Eating Disorders in Teens
The causes of teen eating disorders can range from social media to family pressures to genetics. It is important to learn more about the causes of teen eating disorders to help determine if your son or daughter may be at risk.
Societal and Cultural Pressures
Images on social media can set unrealistic beauty standards for most teens, who end up comparing themselves to the people they see. Most develop negative self-images or feel bad about themselves.
Some teen friends may also directly encourage unhealthy eating habits among each other. Others may feel indirect pressure to conform to the behavior and appearance of their peers.
The fitness culture often introduces the idea of an “ideal” body, which may mean being slim, lean, or muscular. This can pressure teens to meet these body shapes by excessive and compulsive exercising or unhealthy eating habits.
While “clean eating” trends may be well-intentioned, some teens often obsess over them. Skipping meals and avoiding social situations become a downward spiral toward eating disorders.
Family and Environmental Factors
Parents over-involved in their children’s lives may unintentionally deprive them of a sense of freedom, which can result in attempts by teens to restore their independence. They may indulge in unhealthy eating habits to control how their bodies look and feel. Some teens may also be sensitive to comments about weight or food consumption. They may feel a need to change their bodies through unhealthy eating habits to conform to their ideas of “ideal” weight or body shape.
Academic or extracurricular expectations can also overwhelm adolescents. When healthy coping mechanisms can’t manage their stress, they may turn to unhealthy habits to ease the pressure. Some may binge eat to cope with the stress. Since binge eating can cause more stress, an unhealthy cycle forms.
Psychological and Biological Factors
Mental health conditions often precede eating disorders, and many people with eating disorders have co-occurring mental illnesses, including teen depression, anxiety, and obsessive-compulsive disorder.
Genes also contribute to high risks of eating disorders in some individuals. Research suggests that genetics contribute to 40 to 60 percent of the susceptibility to eating disorders. Another study also indicates that people who develop eating disorders like anorexia nervosa may have different brain structures and functions from people without it, predisposing them to the condition.

Enhancing understanding: You will not easily miss important information.
Improving your relationship: Your teen will feel understood and acknowledged.
Enabling you to identify problems: This way, you can help your teen navigate the challenges they’re undergoing.
When to Seek Professional Help
