Eating disorders are a category of mental illnesses that relate to disturbances in thoughts, attitudes, and behaviors toward food, eating habits, and/or body size or weight. While they can affect people of any age, gender, race, or size, they’re most common in younger adults. In fact, statistics show that 95% of those with eating disorders are between the ages of 12 and 25. Since these illnesses can be both physically and physiologically damaging and even fatal, it’s important for teenagers and parents of teenagers in particular to recognize the signs and symptoms of eating disorders and to understand that effective treatment is available.

Types of eating disorders

Per the National Eating Disorders Association, there are eleven different classifications of eating disorders that are characterized by different kinds of behavior patterns.

That said, all forms of eating disorders have the potential to impact daily functioning, cause severe complications, and be dangerous for physical and mental health overall. With proper diagnosis and treatment, though, recovering from an eating disorder is possible. 

It’s important to note that individuals of any weight, body shape, or size can have an eating disorder, even those that are considered to be at a ‘healthy average weight’ or ‘overweight’ according to the body mass index. Three of the most common eating disorders in teenagers are listed below. Keep in mind, however, that some people may experience symptoms from multiple eating disorders, other eating disorders not mentioned here, or other mental health conditions in addition to an eating disorder. 

Anorexia nervosa

Often referred to simply as “anorexia,” this eating disorder involves severely restricting food intake. It can result in a low and even life-threatening body weight and/or damage to various body systems, which may shut down altogether if the condition is left untreated. A distorted body image, a deep fear of gaining weight, and a compulsion to tightly control caloric intake are hallmarks of this disorder. The dangerous behaviors associated with it are often unhealthy mental coping mechanisms that result from unaddressed emotional problems.

Bulimia nervosa

Often referred to simply as “bulimia,” this eating disorder involves a cyclical intake and output of food. It can result in dehydration, serious cardiac and digestive problems, and mouth, gum, and teeth diseases or issues. People with bulimia nervosa often binge eat or consume food in excess in a short amount of time, and then engage in purging behaviors such as forced vomiting, exercising excessively, or taking laxatives to rid themselves of the calories as quickly as possible. These behaviors are typically related to a poor self-image and a low self-worth.

Binge eating disorder (BED)

Now officially recognized as a distinct diagnosis in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), binge eating disorder is characterized by the regular consumption of unusually large amounts of food and a lack of control over what or how much one is eating. Unlike anorexia nervosa and bulimia nervosa, people with binge eating disorder do not experience the compulsion to compensate for the calories consumed during a binge eating episode. Instead, they may experience feelings of shame and embarrassment related to their behaviors. BED can be life-threatening and damage various organ systems over time. Binge eating disorder is now the most common eating disorder in the United States.

Avoidant/restrictive food intake disorder (ARFID)

Avoidant/restrictive food intake disorder is also characterized by rigid eating habits, like anorexia nervosa, but for different reasons—such as because of an aversion to the color or texture of certain foods, fear of choking, or a lack of interest in food. This food intake disorder is more common in children and adolescents. Being a picky eater is not the same as experiencing an avoidant/restrictive food intake disorder like this, because it can lead to being significantly underweight and experiencing mental health challenges as well. As the Child Mind Institute reports, ensuring that a child gets treatment for this intake disorder as soon as possible can help decrease the likelihood of health complications and of continuing to experience symptoms into adulthood.

Risk factors for developing an eating disorder

Eating disorders may occur as a result of a combination of biological, psychological, and environmental factors. The following may put an individual at a higher risk for developing an eating disorder:

  • Having a family history of eating disorders or other mental health conditions
  • Early childhood trauma or abuse
  • Frequent dieting
  • Certain personality tendencies like perfectionism
  • Poor body image
  • Experiencing bullying
  • Being in a social situation or environment that encourages eating disorders
  • Having another mental illness such as an anxiety disorder, obsessive compulsive disorder, depression, post-traumatic stress disorder, or substance use disorder

Symptoms of eating disorders

Since there are about a dozen distinct eating disorders, there’s no single set of symptoms that indicate that you or a loved one may be experiencing one. That said, there are some general signs that may mean you or this person could benefit from professional attention.

Warning signs for an eating disorder

  • A preoccupation with food and eating
  • A preoccupation with body size and/or weight
  • Avoiding eating around others or entering social situations that involve food
  • Hiding, being secretive, or lying about food or eating
  • Social withdrawal
  • Feelings of guilt and shame around food
  • A warped image of their own body
  • Significant weight loss or dramatic weight fluctuation

Society and media can be a factor in developing anorexia and other eating disorders

Society and media send all kinds of distorted messages about food, eating, weight, and body that can contribute to an unhealthy view of one’s own body and eating habits. Some research indicates that there is a link between social media and eating disorders like anorexia and bulimia. Specific eating habits can also be a coping mechanism for people who are facing emotional problems, stress, or mental health disorders. If you or a loved one is experiencing attitudes or behaviors around food and eating that are causing or contributing to anxiety, a disruption in daily functioning, or physical or mental health difficulties, seeking help is recommended.

Treatment for eating disorders

It’s important to understand that eating disorders are clinical mental illnesses. They typically can’t be resolved simply through willpower or the encouragement to develop a healthy diet. The root of these disorders usually runs much deeper, with problematic eating habits simply being a manifestation of emotional problems that need to be addressed. That’s why psychotherapy is a common component of treatment for a range of different eating disorders. 

Cognitive behavioral therapy

Cognitive behavioral therapy (CBT) in particular has been suggested to be an effective intervention in many cases, according to research, because it’s all about changing warped thought patterns in order to help shift unhealthy behaviors and improve mental health. Depending on the condition and its severity, nutrition education and medical interventions may also be a necessary part of treatment. If anxiety, depression, or substance use coexist with an eating disorder, these conditions may be treated through psychotherapy, medication, or both.

Guidance from the National Eating Disorders Association

According to the National Eating Disorders Association, “early identification and treatment [for eating disorders] improve the speed of recovery, reduce symptoms to a greater extent, and improve the likelihood of staying free of the illness.” That’s why knowing the common warning signs can be so important. If you feel that you or a loved one is exhibiting some of them, seeking professional support can make a big difference in the possible outcomes. Even if you’ve just started to notice some potentially unhealthy or troubling thoughts or beliefs related to food and eating in yourself or someone in your life, finding a mental health professional to discuss them with can help prevent them from developing into a more serious condition.

Seeking therapy for eating disorders

If you or your child has developed worrying or dangerous behaviors around food and eating, you may want to begin by meeting with their doctor. In addition to whatever tests or treatments they may propose, you’ll likely also be encouraged to make an appointment with a mental health professional. For more serious symptoms or severe/advanced cases, in-person treatment with a therapist or psychologist will likely be recommended. For mild to moderate cases or those just noticing initial concerns about food attitudes and eating habits, online therapy may be an option.

Online therapy for anorexia and other eating disorders

In general, studies suggest that virtual therapy may offer similar benefits to in-person sessions for a range of conditions like depression and anxiety. It can also be effective for anorexia. For eating disorders in particular, recent research suggests that online CBT may be beneficial, especially since it “enables individuals to overcome barriers they may experience with face-to-face treatments, such as stigma, travel time and costs and availability.” One convenient option for online mental health care for teenagers is a virtual therapy platform like TeenCounseling. With parental consent, it can match those aged 13–19 with a licensed mental health professional who they can meet with via phone, video call, and/or in-app messaging from home or anywhere with an internet connection.

Can online therapy treat bulimia and binge-eating disorder?

Besides anorexia, online therapy is also found effective in reducing the symptoms of bulimia nervosa and binge eating disorder. If the provider determines virtual therapy to be a good fit for your teen’s particular situation, it can be a potentially effective treatment for those who are experiencing an eating disorder or who may be at risk for developing an eating disorder. A therapist can provide a safe space in which your teenager can express and unpack their emotions, identify and shift any warped or unhealthy thought patterns around food and eating, and learn healthier coping mechanisms for dealing with emotional challenges.

He’s helped me work through a lot of things I’ve been holding onto for years and my friends and family have seen a noticeable difference in my happiness and positivity since I started working with him. He’s totally spot on. Very professional and kind."

Takeaway

Eating disorders are mental illnesses that can’t simply be overcome with willpower or simple dietary changes. In general, the emotional challenges causing them must be addressed by a mental health professional for recovery to be possible. Early identification and treatment can greatly improve one’s chances of healing from an eating disorder.
