An eating disorder is an illness that causes serious disturbances to everyday diet, such as eating extremely small amounts of food or severely over-eating. A person with an eating disorder may have started out just eating smaller or larger amounts of food, but at some point, the urge to eat less or more spiraled out of control. Severe distress or concern about body weight or shape may also signal an eating disorder. Common eating disorders include anorexia nervosa, bulimia nervosa, and binge-eating disorder. Most eating disorders involve focusing too much on weight, body shape and food, leading to dangerous eating behaviors. These behaviors can significantly impact body's ability to get adequate nutrition. Eating disorders can harm the heart, digestive system, bones, and teeth and mouth, and lead to other diseases.
