Anorexia, bulimia and binge eating disorder are common eating disorders, claims the National Institute of Mental Health. Eating disorders are caused by genetic, behavioral, psychological and biological factors.
People suffering from anorexia have an intense fear of being overweight, although they are not. They may exercise too much, use laxatives and eat fewer calories in attempts to continue weight loss. Anorexia primarily affects young women, although it can affect anyone, claims Everyday Health.
People with bulimia have a habit of binging on food and then purging it. They feel as if they cannot control the eating binges, and think obsessively about food. Binge eating disorder makes a person unable to control the amount of food consumed. It is also known as emotional eating or food addiction. People with binge eating disorder tend to be overweight, claims Everyday Health.
