Someone with this disorder has a constant fear of gaining weight because they fear of becoming fat, or just want to control their weight and shape of their bodies. These people do not eat, or eat very very little throughout the day, to prevent gaining weight, which can impact their health severely. People with this disorder also can exercise excessively, and even if they lose weight, their fear of gaining weight does not go away. Many with anorexia have this drive for thinness and this disorder can be a way to deal with emotional issues. Anorexia is very life threatening and can be super detrimental to someone's health. People with anorexia often have a distorted view of their own body.
