Is Anorexia in Your Genes?

Scientists are continually learning more about the origins of anorexia and other eating disorders. In a study published in the journal Molecular Psychiatry, researchers at the Children’s Hospital of Philadelphia discovered that anorexia nervosa may be linked to particular DNA variations.

The study analyzed the frequency of genetic variants called single-nucleotide polymorphisms (SNPs) in the DNA of more than 1,000 people with anorexia, primarily young women.

The researchers found that two specific SNPs were associated with an increased incidence of anorexia. While previous studies have shown that genetics play a role in the development of anorexia, this is the first to connect specific variants in DNA with the disorder.

More research in this area is necessary to fully understand the genetic basis of anorexia and other eating disorders. Currently, no genetic screening exists to determine who is at risk for developing anorexia.

While you cannot know definitively if anorexia is in your genes, a close look at your family history may offer helpful insights. In the future, experts may be able to create a genetic profile for anorexia or even offer gene-replacement therapy as a treatment for anorexia. Until then, those suffering from anorexia may benefit from a stay in an eating disorder treatment center that combines medical care and nutrition counseling with intensive therapy.
