_Lamy_, for example, has made an elaborate study of one of the above-mentioned symptoms of uterine dyspepsia, namely, excitement of the vomiting centre. His conclusions are as follows: Among the general symptoms of diseases of the uterus, dyspepsia, in all its forms and in all degrees of intensity, occupies the first rank in respect of frequency of occurrence. Among the accompaniments of these reflex processes, uterine vomiting must be mentioned. It seldom occurs as the sole symptom of disorder of the digestive organs; but when it does occur alone, it is of great importance that the cause of the affection should not be misunderstood. Diseases of the uterus and periuterine affections are the conditions that most commonly give rise to this trouble, but in a certain number of cases it is due to physiological changes in the female genital organs. Such changes are those associated with the functional activity of the reproductive apparatus at the time of puberty, during menstruation, in connection with coitus, during pregnancy, and at the change of life, the menopause. The vomiting of pregnant women is of the same nature, and confirms our belief in the uterine origin and pathogenesis of vomiting at other times than during pregnancy. The diagnosis of the true cause of uterine vomiting cannot be made from the nature of the latter, but only from a knowledge of the conditions in which it occurs, just as with other uterine reflexes, such as neuralgia or cough. The vomit may consist merely of the food last taken, or it may contain bile, without the presence of this latter constituent indicating the existence of any disease of the liver. The treatment of this disorder, which indeed does not threaten life, but does seriously impair the general state of nutrition, must be local, directed against the disease of the genital organs: Thus, in one case of this nature, a cure was effected by oöphorectomy.
