Eating Disorders 101

Eating disorders are complex illnesses with biological, genetic, psychological, social, and developmental roots. They come in all shapes and sizes and they do not discriminate between age, gender, race, class, sexual orientation, socioeconomic background, or ethnicity. It is impossible to know whether a person suffers from an eating disorder, or its severity, solely on the basis of appearance.

Eating disorders are not a choice.
They are real, life-threatening illnesses with potentially fatal consequences.

With 1 death every 52 minutes occurring in the U.S. as a direct result of an eating disorder, eating disorders have the second highest mortality rate of any mental illness.

With early intervention, full recovery is possible.
With treatment, the mortality rate of people with serious eating disorders falls from 20% to 2-3%.

Disordered eating vs eating disorders:
Disordered eating behaviors (including dieting) can be precursors to eating disorders.  Disordered eating may include (and is not limited to) a rigid food and exercise regime; feelings of guilt or shame when unable to maintain said regime; a preoccupation with food, body, and exercise that has an impact on quality of life; compulsive eating; compensatory measures to ‘make up for’ food consumed (i.e.:  excessive exercise, food restriction, fasting, purging, and laxative or diuretic use); and weight loss supplement use. Checking-in with intentions behind and behaviors around food and exercise may be helpful in determining if it is an unhealthy relationship. Eating disorders may include the behaviors mentioned but they are complex psychiatric illnesses with biological components and they can be life-threatening. When an individual is struggling with an eating disorder, they generally engage in multiple behaviors with more frequency and intensity. The level of obsession with food, exercise, and body thoughts and behaviors can distinguish disordered eating from an eating disorder. These thoughts are generally all-consuming and may include (but are not limited to) fixation on calories; good and bad foods; ingredients; measurement; taste; body size and shape; type and frequency of exercise; feelings of failure when unable to sustain these behaviors; and avoidance of social activities.

While awareness of “typical” signs/symptoms of the more “familiar” eating disorders is critical, it is also important to note that there is a spectrum of maladaptive behaviors (some close to becoming official diagnoses and some not close enough), and that disordered eating and eating disorder symptoms can manifest at different times and overlap.

About Other Specified Feeding and Eating Disorders (OSFED)
Individuals suffering from maladaptive thoughts and behaviors related to food, eating, and body image but who do not meet all of the diagnostic criteria.  The category was developed to encompass those individuals who did not meet strict diagnostic criteria for anorexia nervosa or bulimia nervosa but still had a significant eating disorder.  Research into the severity of OSFED shows that the disorder is just as severe as other eating disorders.  Examples include:  Orthorexia (the harmful obsession with the quality or purity of food and ‘healthy’ eating), over exercise/exercise compulsion, Body Dysmorphic Disorder, and Diabulimia

If this list causes any level of concern, or thoughts about food, weight, exercise routine, body shape or size are taking a predominant role, seeking professional help for early detection is strongly encouraged.
