What is an Eating Disorder?
Eating disorders are classified as a mental health illness, according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5).
Eating disorders cause an individual to have a distorted view of their body image and relationship with food. Individuals with eating disorders often obsess over their weight and dieting, which can lead to unhealthy and dangerous behaviors.
There are a few main types of eating disorders:
anorexia nervosa
bulimia nervosa
binge eating disorder
ARFID (Avoidant/Restrictive Food Intake Disorder)
OSFED (Other Specified Feeding and Eating Disorders)
UFED (Unspecified Feeding or Eating Disorder), among others.
While the signs, symptoms, behaviors, and presentation of the types of eating disorders can greatly vary, each type of eating disorder can have serious consequences on an individual's physical, emotional, and psychological health.
Some eating disorders are characterized as the restricting type, in which individuals lose weight primarily by dieting, fasting or excessively exercising. Others are characterized by binge-eating/purging type in which persons engage in intermittent binge eating and/or purging behaviors.
If you or someone you know is struggling with an eating disorder, it is important to get help from a professional. Treatment involves physician-supervised care that may include nutrition therapy, psychotherapy, medication management, and support groups. Don't suffer in silence-seek help today.
What Causes an Eating Disorder?
The causes of eating disorders are multifactorial, including but not limited to:
biological/genetic - a family history of an eating disorder is a risk factor for developing an eating disorder
psychological (anxiety/depression, poor body image and/or self-esteem)
perfectionism
societal norms and values
familial relations and influences
history of physical or sexual abuse
Thus, it can be difficult to prevent eating disorders because the causes greatly vary from individual-to-individual. In the majority of cases, whether you or your loved one have an eating disorder, an eating disorder is not your fault.
Eating disorders may develop in response to a trigger, such as a major life event or change (like starting college or a parents' divorce) or a traumatic experience (like sexual abuse). But sometimes, there is no obvious trigger for why an Eating Disorder develops. Teens are especially vulnerable to developing an eating disorder because of the pressure they face to conform to variety of societal standards and norms. About 85% of all cases of eating disorders begin during adolescence. It is important to recognize signs of an eating disorder early so that the affected individual can receive help promptly before the eating disorder worsens.
