Eating disorders are real, complex illnesses that can cause serious harm. Eating disorders are characterized by a disturbance in an individual’s eating and food behaviors or self-perception. Common warning signs of eating disorders are extreme weight changes, altered eating behaviors, or an intense fixation on food and body talk. Eating disorders are biologically-based brain illnesses that are affected by environmental, social, and psychological factors. This means that illness is not caused by one specific factor, but rather by a series of factors in an individual’s unique life experience.
Types of Eating Disorders
Due to the complexity of eating disorders, the DSM-5 divides eating disorders into the following five categories:
Anorexia Nervosa. Anorexia is noted by extreme food restriction that causes dramatic and prolonged weight loss. It often presents with body dysmorphia and a genuine fear of food.
Avoidant/Restrictive Food Intake Disorder (ARFID). ARFID includes feeding or eating disorders that involve a lack of interest in or an avoidance of certain foods that result in a failure to meet nutritional needs. ARFID, unlike anorexia, does not include a drive for thinness.
