What is Anorexia Nervosa?
Anorexia nervosa (AN) is an eating disorder in which a person is at an extremely low body weight but fears gaining weight. A person with AN may also experience their body as heavier or bigger than it truly is. They may also consider their body weight and/or shape to be one of the most important things that determines their self-worth or self-esteem. They may not realize how medically dangerous being underweight is for their health.
AN is a serious mental health disorder that affects a person's physical and mental health. Over time, these behaviors can cause serious damage to the body. In some cases, the behaviors can lead to death.
What are the Different Types of AN?
The two types of AN include:
- Restricting type is when a person with AN only restricts or limits how much food they eat. They eat far fewer calories than needed to keep a healthy body weight.
- Binge-eating/purging type is when a person with AN sometimes feels out of control when they eat. They might also use certain purging behaviors, such as vomiting, use of laxatives or diet pills to make up for the calories they eat.

- Certain psychological traits (such as perfectionism, obsessive-compulsive behaviors, anxiety or depression)
