This report establishes that anorexia is now becoming a metabolic and psychiatric disorder.

A study conducted by researchers at King’s College London and the University of North Carolina at Chapel Hill concluded that anorexia is not only due to psychological factors, but also to genetic and metabolic factors.

This is a fact that changes the parameters of everything we knew about this nervous disease based on not eating because those who suffer from it see a body different from the real one, among other circumstances.

Metabolic and psychiatric disorder

This report establishes that anorexia now becomes a metabolic and psychiatric disorder, since the genetic basis of anorexia nervosa is the result of metabolic, lipidic and anthropometric characteristics. Thus, according to the study, some patients are taking treatment for anorexia but continue metabolic deregulation and do not regain weight.

Steps and conclusions

To achieve this result, research focused on genetic analysis of more than 15,000 people with anorexia nervosa and 55,525 healthy people, all from different parts of the world.

Thus, it has been proven that the eight areas of the genome that respond to anorexia nervosa were related to other psychiatric disorders (more or less known) and metabolic disorders, such as diabetes or fat metabolism, previously observed.

Metabolic developments as psychiatric factors

This study is important because until now, it was believed that metabolic changes in these patients did not affect dietary intake. But it is now believed that such metabolic traits can have a similar influence to psychiatric factors in the development of this disease.

People with anorexia nervosa feel that they have a intense fear of gaining weight or gaining weightand they’re overly worried about their silhouette. According to the Association against Anorexia and Bulimia, there are abnormal behaviours in terms of diet, weight, volume and body shape.

The diagnostic criteria for anorexia nervosa are as follows restriction of energy supply which results in a significant decrease in weight, taking into account age, gender, developmental trajectory and physical health. Intense fear of gaining weight or becoming obese, or persistent behaviour that interferes with weight gain, and altered perception of body weight and body shape, among others.
