What is Anorexia Nervosa?

At any given moment, several million individuals could be feeling the effects of a anorexia nervosa  While development of an eating disorder often develops in adolescence and the most common demographic is women between the ages of 12 and 35, anorexia can affect people of any age, gender, race, ethnicity, or sexual orientation. In recent years there has been an increase in anorexia in children and middle age individuals. Eating Disorder Hope says that 10 million women and 1 million men in the United States find eating disorders to be a daily struggle. 

According to the American Psychiatric Association,  those who experience anorexia nervosa tend to be overly critical of themselves as well as their bodies. They also may continue to perceive they are overweight even if they are experiencing semi-starvation or even malnutrition, two conditions that are life threatening. Furthermore, those that develop anorexia  may do so in tandem with other psychiatric issues including obsessive compulsive disorder (OCD), anxiety, as well as substance use disorders. 

Diagnostic Criteria for Anorexia Nervosa

Physicians and licensed mental health professionals can diagnose a patient with anorexia nervosa if the individual is experiencing the following hallmarks of the disorder which include:  

  • An intense fear of gaining weight or being “fat”
  • Limited intake of food which leads to significant weight loss

Distorted perception of body image and/or a denial that there is a problem. Those who are experiencing anorexia nervosa severely restrict their food intake and may use compensatory behaviors such as excessive exercise, laxative abuse, and self-induced vomiting, all of which lead to the maintenance of a low weight. With that said, having a low weight is not a requirement of anorexia nervosa. Individuals of all body sizes can suffer from anorexia.

As an individual experiencing anorexia nervosa heads towards full-on starvation, they may develop other physical symptoms, including:

  • Brittle hair and nails

What Causes Anorexia Nervosa?

While the exact cause of anorexia nervosa remains unknown, the Mayo Clinic speculates that it is likely a disease that comes from a combination of psychological, biological, and environmental factors. There are also several factors that could increase one’s risk of anorexia, including genetics, transitions (such as a move or a new school), and dieting.
