The media is a major factor in the increased incidence of anorexia nervosa: according to a 2000 study by Tiggemann et al., "the factor exerting the greatest pressure to be thin was the media”. Social media in particular has led to the epidemic of anorexia among young women. A study by Field et al. (2001) argue that the media is to blame for encouraging girls to pursue the idea of ​​achieving an unrealistic body type. People are constantly bombarded with advertisements and posts from the various social media sites they are members of; some messages found on these sites evoke negative feelings and perceptions regarding body image. Such emotions can lead to various behaviors that can change a person's appearance, such as excessive diet and exercise. Taken to the extreme, such behaviors are diagnostic of anorexia nervosa, considered one of the deadliest mental illnesses (Birmingham et al. 2005). According to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSMV), anorexia has two subtypes and its diagnostic criteria includes three components. The two subtypes are the restrictive subtype, when one is unable to eat, and the binge eating/purging subtype, when one eats excessive amounts and then purges. Purging can be induced by laxatives or by inducing vomiting with a finger or object. According to the most recent edition of the DSM (American Psychiatric Association, 2013), the diagnostic criteria for anorexia nervosa are divided into three parts: The first is the refusal to maintain body weight at a normal level (the weight calculated for your age and height), or the inability to gain the expected weight during a period of growth. The second is the intense fear of strange behavior middle of paper on Pinterest. Proceedings of ICWSM.
