The biological approach as an explanation for eating disorders

This approach considers the possibility of infection which is an unlikely cause of eating disorders. It also focuses on:
 - genetic vulerability - by looking at twin studies;
 - environmental factors;
 - biochemical factors such as endocrine dysfunction and changed hormone levels.
 This spproach has been criticised in that:
 - There is not a 100% concordance rate for monozygotic twins.
 - Changes in biochemistry may be the result of the disorder, rather than the cause.
 - Care needs to be taken befote generalising research finding based on animals to humans.
