Almost every physician is called on to treat patients who may have functional vomiting. If he is aware of the characteristic clinical features these individuals present and the variety of methods which have been reported to be successful in treatment, he will avoid some of the unfortunate procedures to which many such patients have previously been subjected. As a result of a recent review of 140 cases seen at the clinic in which a diagnosis of functional vomiting was made, we have been particularly impressed by the characteristic features which many of these patients present and by the relatively large number who have undergone surgical procedures with the expectation that a lesion would be found and a successful surgical result accomplished. It seems worth while therefore to emphasize some of these clinical features of functional vomiting concerning which there is relatively little to be found in the literature.
