About Eating Disorders

Eating disorders are complex conditions that emerge from biological, psychological, and social factors. While eating disorders manifest themselves in symptoms related to disordered eating and body image concerns, they are about more than food, shape, or weight. They often are used to help regulate painful emotions, decrease anxiety, cope, and feel in control.
Over time, eating disorders can damage self-esteem and body-esteem and lead to mental and physical health complications, chronic illness, disability, and poor quality of life. Eating disorders have the highest death rate of any psychiatric illness.

Types of eating disorders include:

Anorexia Nervosa

    • Restriction of food intake leading to a significantly low body weight
    • Intense fear of gaining weight or becoming fat, even though underweight
    • Self-esteem overly related to body image
    • Anorexia Nervosa is the 3rd most common chronic illness in girls ages 15-19. It affects approximately 1 percent of women and .3 percent of men

Bulimia Nervosa

    • Repeated episodes of binge eating, which include:
      • Eating separately in a certain amount of time (within a 2-hour period) large amounts of food.
      • A feeling of being out of control during an episode
    • Repeated behavior in order to prevent weight gain (purging, self-induced vomiting).
    • The binge eating and purging behaviors both occur, on average, at least once a week for three months.
    • Self-esteem is heavily influenced by body shape and weight.

Binge-Eating Disorder

    • Indications that the binge eating is out of control, such as eating when not hungry, eating to the point of discomfort, or eating alone because of shame about the behavior.
