Describe the potential causes of anorexia nervosa.?

Question

What will be an ideal response?

Answer 1

ANSWER:
?Characteristics that seem to be correlated with anorexia include perfectionism and faulty thinking about food (for example, thinking one should never eat carbohydrates), as well as biochemical abnormalities. Many people with eating disorders also have personality disorders—characteristic, maladaptive ways of dealing with the world. We do not yet know if these are causal factors or merely factors that correlate with eating disorders.

Another piece of the puzzle may be genetics. Some scholars have argued that genes for anorexia evolved to allow our ancestors to survive famine by helping them ignore food while migrating to better environments. Indeed, evidence supports the idea of a genetic basis for anorexia. If one identical twin is anorexic, the other twin’s chances of becoming anorexic are drastically increased. However, having a fraternal twin who is anorexic only modestly increases one’s chances of becoming anorexic. This pattern of results supports the existence of a genetic predisposition to anorexia. It is also common to see family members, particularly mothers and daughters, who both have eating disorders. However, this doesn’t necessarily indicate a genetic basis for the disorders as family members also tend to have shared environmental influences. At present, it appears that both bulimia and anorexia may result from a complex mix of cultural factors, personality characteristics, environmental issues, and biological factors.
