Metabolic factors likely contribute to anorexia
Scientists defined that anorexia nervosa as a metabolic as well as a psychiatric illness. They are suggested that treatments should address the hybrid nature of the potentially lethal eating disorder.
The international team with more than 100 researchers studied about the DNA of tens of thousands of people with and without anorexia nervosa.
A Nature Genetics paper describes that how they identified eight genes with a strong link to anorexia nervosa.
Some of the genes have common links with other psychiatric illnesses, such as schizophrenia, depression, anxiety, and obsessive-compulsive disorder.
However, the findings also reveal genetic links to physical activity, the metabolism of glucose, how the body uses fat, and body measurements. In addition, these links will appear to be independent of common genetic ties to body mass index (BMI).
However, the new findings about the role of metabolism could help explain why people with anorexia "frequently drop back to dangerously low weights, even after therapeutic re-nourishment," she adds.
