Anorexia Nervosa is commonly diagnosed in adolescent females but also in older females and males. It is diagnosed when an individual’s weight is about 15% less than the ideal body weight.


There is no particular cause of this eating disorder but through the combination of several factors such as:

1. Post-Traumatic Stress Disorder: Individuals with past trauma such as sexual or physical abuse have the tendency of following a strict diet to cope with the disturbing emotions they experience.

2. Sociocultural factor: Cultures which glorify having a “slim body” body type place needless pressure on individuals to achieve the “ideal” body weight and shape, especially as a criterion for getting a job e.g. modelling agencies. The media also has a major role to play as a contributing factor in making the slim body the perfect body type from what’s portrayed on television and other social media platforms.

3. Peer pressure: This is a major factor for which it is common in adolescents. Peers have a role to play in a developing individual and if an adolescent is subjected to bullying and ridicule by peers, it can contribute to both mental health disorders and eating disorders such as Anorexia Nervosa.
