ZINC AND ANOREXIA NERVOSA

Probably the most difficult aspect of the disease anorexia nervosa is that patients start out by dieting rather strenuously and then, after losing a lot of weight, find that they cannot get back to normal again even if they try. Getting these people to absorb food, even after tube feeding, is not always successful.

Now, according to the Lancet (2:350), one patient, at least, has responded dramatically to supplemental zinc, and on the basis of this case, there is hope that zinc will prove beneficial to others.

Zinc deficiency, it is well known, greatly impairs our sense of taste and smell, thereby markedly reducing the appetite. Furthermore, zinc deficiency probably also impairs the absorptive functions of the intestine, the Lancet (2:350) reports, hence explaining the lack of success of tube feedings. It is understandable that as patients become zinc deficient as the result of their dieting, the deficiency makes the situation worse by depriving them of any further desire for food. *36\143\2*
