Identifying the Risk Factors: Causes, Signs & Symptoms of Teen Eating Disorders

Eating disorders are complex and affect all different kinds of people. Although,
adolescents and teenagers are more at risk. There is no one identified cause of teen eating
disorders. Instead, studies cite a number of possible factors, such as
psychological problems, genetic predispositions, family relationships, and sociocultural
issues as potentially contributing to the development of eating disorders in teens.

Different Types of Eating Disorders

Adolescent and teen eating disorders are on the rise. Especially when it comes to
three eating disorders most common amongst young people – anorexia, bulimia, and binge-
eating disorder.

Anorexia

Medically referred to as anorexia nervosa, this eating disorder is defined
by the desire to be thin and intense fear of weight gain. Teens with
anorexia tend to go to extreme lengths to avoid weight gain, including restricting
caloric intake.

Bulimia

Medically referred to as bulimia nervosa, this eating disorder is
characterized by episodes of bingeing. Eating large quantities of food in a short
period of time) and purging (compensating for food intake through self-induced
vomiting, use of laxatives, etc.) behaviors.

Binge-eating Disorder

Characterized by a sense of loss of control around food,
resulting in bingeing. For teens that suffer from binge-eating disorder, there are
often resulting feelings of immense guilt and/or shame.

Obviously, there are other types of eating disorders, but anorexia, bulimia, and
binge-eating disorder affect adolescents and teenagers at the highest rates.

Risk Factors for Eating Disorders in Teens

Although there is a correlation between the desire for the “ideal” body and eating
disorders, there still remains no consensus regarding the precise cause of eating disorders.
Being a long studied area of medical and mental health research, eating disorders
result from one or more biological, social, behavioral, genetic, or environmental factors.
Teenagers are the age population most susceptible to eating disorders. Teens
also tend to deal with the most detrimental side effects of eating disorders as adolescence
is a time period of rapid growth and maturation, and malnutrition and vitamin deficiency
can interfere with normal development. While it is possible for any teen to acquire an
eating disorder, there are certain identifiable factors that make it more likely to occur for
some.

Family history and genetics

Genes are thought to play a big part in increasing
one’s likelihood of developing an eating disorder. This means adolescents and
teenagers are at an increased risk if they have a close relative who has suffered
from an eating disorder.

Anxiety disorders

Research shows a significant subset of youth with eating
disorders also meet criteria for an anxiety-related disorder (i.e. – generalized
anxiety disorder, obsessive-compulsive disorder, social phobia, etc.).

Life changes and transitions

Certain life changes and events can cause emotional
distress and feelings of instability. Major life changes include moving, loss or death
of a loved one, relationship deterioration, etc.

Trauma

Adolescents and teenagers who have experienced abuse (emotional,
physical, or sexual) are more likely to suffer from an eating disorder. Research
indicates a strong correlation between past trauma and eating disorders.

History of dieting

In this day and age in America, weight loss is frequently met
with positive reinforcement. Many youth are motivated by these affirmations
around dieting. sometimes becoming excessive, which can (often very quickly) lead
to the development of an eating disorder.

Extracurricular activities

Young people who are involved in certain
extracurricular activities or sports are at an increased risk for suffering from an
eating disorder. While competitive sports can be wonderful for a teenager’s health
and confidence, they also often put huge emphasis on physical shape (body shape
and size). This can cause individuals to become body-focused, and unfortunately
for some, this can progress into an eating disorder.

Eating Disorders & Diabetes

Recent studies have cited type-one (insulin-dependent) diabetes as a risk
factor for eating disorders. In fact, one study showed approximately one-quarter of
women diagnosed with type-one diabetes will develop an eating disorder.
Tendency toward perfectionism – perfectionism, which is one of the strongest risk
factors for eating disorders in teens, is the trait of setting unrealistically high
expectations for oneself. Because “perfect” is impossible to achieve, those who
struggle with perfectionism are bound to feel poorly about themselves, experience
guilt/shame, etc., and often turning toward an eating disorder.

Body dissatisfaction

Body image is how a person feels about his or her body shape
and size, and how one personally experiences being in his or her physical body.
Sadly, it is not uncommon (especially in adolescence) for people to dislike their
physical appearance. While it is understandable why some with high levels of body
dissatisfaction develop eating disorders, those with eating disorders actually end
up reporting even higher levels of body dissatisfaction.

Warning Signs of Eating Disorders

Every teenager is unique. When two teens suffer from the same eating disorder, chances
are what caused the eating disorder is different for both. Knowing the possible warning
signs of eating disorders can be helpful in identifying a problem and seeking early
intervention.
