Resources and guidelines for parents who have teens with eating disorders

If you have a teenager with an eating disorder, you’re probably desperate for resources and information to help you navigate this difficult situation. The good news is that we’ve got the resources you need to figure things out and start helping your teen recover from their eating disorder.

Teenagers develop eating disorders for many different reasons. Your teen may have experienced puberty and growth spurts that made them feel uncomfortable in their body. They may be experiencing high levels of stress at school or on sports teams. And, unfortunately, they may be exposed to harmful ideas and ways of thinking about bodies, weight, and eating from their peers and social media. Maybe your teen has always been anxious and perfectionistic, and lately all their attention is on their weight, exercise and eating.

Whatever your teenager’s symptoms are, we can help you understand them and start to take meaningful action to help them recover. Eating disorders don’t have to be a life sentence – people can and do recover.

Eating disorders in teens

It is common for eating disorders to begin in adolescence due to a number of factors. Eating disorders are biopsychosocial disorders, meaning they combine biological, psychological, and social elements, many of which come to the forefront during the teen years.

Teens can develop eating disorders at any stage of adolescence. The symptoms can sometimes be hard to spot for months or even years. The different types of eating disorders in order of how common they are is: other specified feeding and eating disorders (OSFED), binge eating disorder, bulimia nervosa, anorexia nervosa, and avoidant restrictive food intake disorder (ARFID).

What are the warning signs for teens with eating disorders?

Many parents know to watch out for extreme weight loss, skipping meals, and increased exercise patterns. The challenge is that these behaviors are normalized, even glorified in our society. Due to the pressures of diet culture, many teens start out on a well-intentioned lifestyle change. However, it’s easy to slip from dieting into an eating disorder. That’s why parents should know that the No. 1 predictor of eating disorders is dieting. Teens who diet are up to 18x more likely to develop eating disorders than those who don’t.

Parents should watch their teens for warning signs of eating disorders including:

  • Rapid/prolonged changes in weight
  • New food rules, restrictions, and strange eating patterns
  • Anxiety and stress surrounding eating, including refusing to eat with family members
  • Increased exercise programs, including exercising late at night in their bedroom
  • Changes in how interested they are in socializing and school activities

Disordered eating refers to irregular eating habits that do not necessarily meet the diagnostic criteria for an eating disorder. Nonetheless, they negatively impact an individual’s physical and/or mental health. Disordered eating can manifest in the form of restrictive or binge eating patterns, excessive preoccupation with food or body image. It is often linked to feelings of guilt or shame around eating. Disordered eating can be hard to spot due to diet culture.

Disordered eating is a key predictor of an eating disorder. It should be treated quickly and assertively in much the same way as an eating disorder. There is no benefit to waiting, as most disordered eating patterns get worse, not better in time.

How many teens develop eating disorders?

Eating disorders are surprisingly common. Up to 10% of people will develop an eating disorder in their lifetime, and the majority of eating disorders begin in adolescence. Many teens who develop eating disorders also have other mental health conditions, including anxiety, depression, OCD, PTSD, autism, ADHD, and more. Eating disorders in teens more than doubled during the COVID-19 pandemic. Eating disorders tend to be long-lasting unless the person receives comprehensive treatment, so early and assertive treatment is essential.

Recent studies have estimated that 22% of teens struggle with disordered eating behaviors, such as intentional vomiting, caloric restriction, binge eating, overexercise, the use of weight loss supplements and misuse of laxatives.. Disordered eating and eating disorders are particularly common among girls. Behaviors tended to increase with age and among those with a higher body mass index.

What are the risks of teens having eating disorders?

Eating disorders are are currently a public health concern in most mid- and high-income countries because their prevalence in teens has markedly increased over the past 50 years. Furthermore, eating disorders are among the most life-threatening of all mental health conditions and are associated with significant, lifelong medical complications.

Major health complications include electrolyte abnormalities and low heart rate. These may require hospitalization and ongoing monitoring. In addition to a medical crisis, teens with eating disorders are also at risk of malnutrition that can impact their growth and development. Puberty can be paused and growth stalled. These conditions can affect height, bone health, weight, metabolic rate, and more. Many of these health risks can have lifelong impacts, which is why getting treatment for teens who have eating disorders is vitally important.

What are the treatments for teens with eating disorders?

Many times the most effective treatment for teens with eating disorders is done at home by parents with the help of trained professionals.

Treatment for teens with eating disorders varies based on numerous factors. These include the teens’ medical status, degree of disordered behavior, access to care, and insurance coverage. While most people assume that teens with eating disorders require hospitalization and residential treatment, the majority of teens can be and are most effectively treated at home.

However, the lack of hospitalization and residential treatment should not be an indication that the teen is not in need of assertive care. Eating disorders don’t typically resolve on their own, they tend to get worse, and every month of having an eating disorder makes it more likely that it will continue indefinitely. Early, assertive treatment is essential to full recovery of eating disorders. The first step is to contact your child’s doctor or find a Certified Eating Disorder Registered Dietitian (CED-RD). They can help you establish a plan and evaluate your options.

Parents are essential to at-home care for teens who have eating disorders. In many cases they can work closely with medical providers, registered dietitians (RDs) and therapists to set up a feeding and care structure that makes sense for them.
