As regards the relations of gastro-intestinal affections to the diseases of the reproductive organs, _Theilhaber_, in the cases observed by himself, distinguishes three groups. In the first group of cases, the gynecological abnormality was a chance accessory, and was not the cause of the gastric trouble. In the second group, he regards the gynecological trouble as dependent upon the affection of the gastro-intestinal tract, believing that, in consequence of atony of the intestine and an accumulation therein of fæces and flatus, a retardation of the circulation occurs in the region of the inferior vena cava, resulting in venous stasis in the uterus, and so giving rise to metrorrhagia, dysmenorrhœa, and fluor albus. In the third group of cases, _Theilhaber_ believes that the uterine trouble is the cause of the disturbances in the stomach and intestine. He, like myself, has found in all these patients an inhibition of the intestinal movements; but he found, on the other hand, that the gastric secretions were more commonly normal, and that only in a small proportion of the cases was the vomiting centre excited. Further, in the majority of these women, the course of the digestive processes was quite normal; and, finally, in his series of cases, endometritis was one of the commonest causes of consecutive gastric disorders. His observations led him to conclude that “in consequence of affections of the uterus a large number of different symptom-complexes of gastric trouble occur:” the pure nervous dyspepsia of Leube, dependent on atony of the large intestine and atony of the stomach, hyperchlorhydria and anacidity, periodic gastralgia without anatomical cause, etc. _Cardiopathia Uterina._ I use the term _cardiopathia uterina_ to denote the manifold cardiac disorders which occur in women as reflex processes excited by the physiological functions and the pathological disorders of the genital organs, and take the form of very various disturbances of the cardiac function. Every phase of the sexual life of women—that in which the reproductive organs attain complete development and menstruation first appears (the menarche); the commencement of sexual intercourse; pregnancy, parturition, and the puerperium; finally the retrogressive process at the climacteric age, of which the menopause is the outward manifestation—may give rise to the occurrence of such cardiac troubles. In order to explain these troubles as reflex in their nature, we must on the one hand recur to the anatomical changes in the uterus and its annexa that take place in every one of the above-mentioned phases of the sexual life; and on the other hand we must take into consideration the mental processes that accompany these anatomical changes, in order to estimate their influence upon the motor and sensory nerves of the heart (see the sections on the _Menarche_ and the _Menopause_).
