An Eating Disorders is a condition in which a person eats and obsesses over their weight in a abnormal ways. These disorders are marked in extremes, with sufferers either eating too little or eating too much. For example, Anorexia Nervosa is an eating disorder in which sufferers limit their food intake to dangerously low levels because they think they are overweight (even when they are severely underweight).
Bulimia Nervosa is another eating disorder in which people binge on food and then purge (by vomiting or laxatives) to eliminate the food and calories from their system. The other end of the eating disorder spectrum is overeating. People may overeat to an extreme degree in order to alleviate negative emotions. Body image is a central component in eating disorders with a skewed body image being a common symptom. Eating disorders are often comorbid (occurring at the same time) with other psychological issues such as depression and anxiety.
