Anorexia Nervosa

Risk Factors

A new school, home, job, a breakup, or the death and illness of a loved one, or even change itself can cause emotional stress and increases the risk of anorexia. Stress is also a trigger for those who are already suffering from an eating disorder.

Dieting and Starvation

Starvation and weight loss may change the way the brain works in vulnerable individuals, which may perpetuate restrictive eating behaviors and make it more difficult to return to normal eating behaviors (Mayo Clinic, 1998-2019).

Starvation affects the brain = changes in mood, thinking, anxiety, and reduction in appetite.

Symptoms of of anorexia are symptoms of starvation.
