Eating disorders develop from a complex interplay of genetic, biological, psychological, and socio-cultural factors. While there is no single cause of an eating disorder, certain risk factors can predispose someone to developing one. These include having a family member with an eating disorder, documented cases of untreated mental illness or trauma in the family, difficulties with regulation of emotions or impulsivity, being perfectionistic or achievement-oriented, and being exposed to sociocultural messages that promote thinness or extreme dieting. For example, yo-yo dieting, which is often glamorized in the media, can trigger disordered eating behaviors. And societal pressure to be thin can exacerbate body image issues and lead to unhealthy weight-loss efforts.
