Drug-induced weight gain.

Untoward long term morbidity and mortality and excess non-compliance with treatment may result from the weight gain induced by some drugs used for the treatment of severe psychological disorder. Whilst some weight gain during the recovery from psychological disorder is to be expected, excess weight gain, over and above the patients normal weight, is not necessary to good outcome and can be avoided. Patients vulnerable to excess weight gain can often be identified prior to beginning treatment.
