I refer Anorexia Nervosa just simply as Anorexia ever since I've gotten diagnosed,  Anorexia is an eating disorder characterized by food restriction,  body image fear,  fear of gaining weight,  and a really overpowering mindset of desiring to be really thin. 

It is also a mental disorder defined by abnormal eating behaviors that effects a persons physical or mental health. 

Anorexia often develops during adolenscence or young adulthood that typically makes a major life change.  Treatment of Anorexia often involves restoring the patient back to a healthy weight by giving them a cycle they need to follow.
