Symptoms of Binge-Eating Disorder

During an episode of binge eating, people eat a much larger amount of food than most people would eat in a similar time under similar circumstances. Circumstances and culture are important because the amount considered excessive for a normal meal may differ from the amount considered excessive for a holiday meal. During and after a binge, people feel as if they lost control and are distressed. People with binge-eating disorder do not compensate for the binge by purging (by making themselves vomit or misusing laxatives, diuretics, or enemas), exercising excessively, or fasting. Binge eating occurs in episodes, as opposed to constant overeating.

People with binge-eating disorder may also do the following:

  • Eat much more rapidly than normal

  • Eat until they feel uncomfortably full

  • Eat large amounts of food when they do not feel hungry

  • Eat alone because they are embarrassed

  • Feel disgusted, depressed, or guilty after overeating
