Genes appear to play a significant role (just over half) in contributing to the development of anorexia nervosa. Trigger factors (such as a traumatic loss or extreme stress) and environmental influences (such as culture) also play a role. Additionally, there appears to be a genetic link to binge eating disorder, potentially associated with the genes that influence obesity.
This means that if someone in a family has an eating disorder, it might be more likely, both from a genetic influence as well as from experiences, for another family member to also develop an eating disorder. For this reason, parents with an eating disorder are also recommended to have treatment.
Families play a significant role in identifying, supporting, and caring for people who have an eating disorder. Family-based treatment for anorexia nervosa is seen as an effective intervention for adolescents. Explore resources in your area that offer family-based support as well as separate support for families.
