Untreated eating disorders in teenagers can have long-term adverse health effects and may be fatal. Caregivers and family members can learn about eating disorders to provide emotional support and aid a teenager’s recovery.
An eating disorder is an ongoing dysfunction of eating behavior that can adversely affect physical or mental health.
Eating disorders that can affect teens include anorexia nervosa, bulimia nervosa, binge-eating disorder, and avoidant restrictive food intake disorder (ARFID).
This article discusses eating disorder symptoms, causes, and treatment in teenagers.
In the early stages of an eating disorder, symptoms can be easy to miss. Many people have skipped the occasional meal or do not like certain foods.
As an eating disorder progresses, teens may hide their symptoms from others. For example, they may wear loose clothing or lie about having eaten. Symptoms can also vary depending on the type of eating disorder a person has.
Parents and caregivers may notice changes in a teenager’s weight or behavior surrounding food and mealtimes. Below are specific symptoms for various eating disorders:
Someone with the binge-purge subtype also has episodes where they rapidly consume large amounts of food and then purge it from the body, for instance, by vomiting or using laxatives or diuretics.
Anorexia symptoms include:
- intense fear of increasing weight
- highly restricted eating
- denial or distorted view of their body
- refusal to gain weight or maintain a moderate weight
- self-esteem connected to body shape and weight
- muscle and bone density loss
- brittle nails and hair
- dry, yellow skin
- growth of fine body hair, known as lanugo
- chronic throat pain or inflammation
- swollen salivary glands
- dental issues such as pain, worn enamel, and tooth decay
- acid reflux
- gastrointestinal issues
- electrolyte imbalance, potentially leading to heart attack or stroke
Binge-eating disorder features recurring episodes of eating a large amount of food, beyond what someone needs to satisfy their hunger. After each episode, the person does not take measures such as purging or excessive exercise.
Of all the eating disorders doctors have identified in the United States, binge-eating disorder is the
- regularly eating a large amount of food in a small amount of time
- eating past the point of fullness
- eating quickly
- frequently trying to diet
- experiencing shame relating to eating
- eating while no one else is watching
Avoidant restrictive food intake disorder (ARFID)
A person living with ARFID restricts their food intake for reasons that
- extremely fussy eating
- lack of appetite
- disinterest in food
- feeling ill at mealtimes
- fear of choking
- weight loss
- gastrointestinal issues with no known cause
- limited range of acceptable foods
The causes of eating disorders are complex. However, a combination of factors
- Biological factors: There is
some evidencethat genetics play a role in eating disorder development. Serotonin may also affect the development of eating disorders due to its role in mood regulation and appetite.
- Socio-cultural factors: Media and cultural values promoting thinness may contribute to eating disorder development in teenagers.
- Developmental factors: Disturbances to typical childhood development may increase the risk of someone developing an eating disorder.
- Behavioral factors: Some types of behaviors may lead to eating disorders. For example, a
2020 studysuggests that the development of eating disorders can result from dieting.
- Psychological factors: The American Psychiatric Association states that eating disorders often co-occur with mental health conditions such as mood disorders and obsessive-compulsive disorder (OCD).
Complete recovery from an eating disorder is easier if treatment begins early. The longer someone lives with an eating disorder, the greater the chance they may experience medical complications or adverse mental health effects.
Eating disorder treatment
- Psychotherapy: Therapy can be individual, group, or family-based. Cognitive behavioral therapy (CBT) is a first-line treatment for eating disorders. However, family therapy may also help teenagers with eating disorders.
- Medication: When eating disorders co-occur with conditions such as depression or mood disorders, medications to treat those issues can help. Doctors may also prescribe medication such as fluoxetine (Prozac) for some eating disorders.
- Nutrition counseling: Nutrition therapy helps a person change their relationship with food so they can stabilize their body weight and nutrient blood levels.
- Medical care: Some teens
may requirehospitalization to stabilize any acute issues relating to malnutrition, as well as to prevent long-term negative impacts by providing feeding support.
A teenager’s treatment plan may depend on the type of eating disorder they have. Aftercare is also important to prevent remission.
Parents and caregivers should seek medical assistance for their teen as soon as they suspect they may have an eating disorder. Early diagnosis and treatment are vital to reduce the risk of complications and further health conditions.
A doctor may also be able to put a caregiver in touch with mental health professionals to help a teenager with mental health conditions alongside an eating disorder.
In addition to getting an eating disorder assessment from a trained medical professional, there are strategies parents can employ at home to help their teen. They can:
- provide nutritious meals and snacks
- discuss the importance of monitoring the body’s hunger and fullness signals
- practice nonjudgmental communication and active listening
- model self-love and acceptance
- value health over appearance
- avoid criticizing people’s body types
- involve their teen in grocery shopping and meal selection and preparation
Eating disorders can be dangerous without treatment because of the adverse effects of malnutrition. The sooner caregivers get help for their teens, the easier it is to stabilize body weight and regain health.
The causes of eating disorders are complex and varied. Sometimes, they co-occur with mental health conditions such as depression or OCD.
Treatment strategies include therapy, medication, medical support, and nutrition counseling.
