The majority of the women in whom _Lamy_ observed this symptom of uterine dyspepsia were chloro-anæmic individuals with an irritable nervous system, town-dwellers, young girls in whom frequent evening parties and dances, ill-chosen diet, and a generally unsuitable mode of life, had led to the development of a “virginal metritis.” The signs of the disturbance of the gastric functions were in the first place a retardation of gastric digestion while the appetite remained good. Moreover, the stomach was often distended with flatus, and this caused frequent gaseous eructations; there was also epigastric pain, which made it difficult for the patient to bear the pressure of the clothing, and sometimes great pain was aroused by the slightest contact. The attacks of vomiting, which occurred in a characteristic manner with periodical intervals of freedom, were usually preceded for a longer or shorter period by dyspeptic symptoms. The vomiting itself, if it occurred immediately after a meal, was not accompanied by nausea, a feeling of faintness, or cold sweats, but rather resembled a kind of painless regurgitation; but when the vomiting did not occur till some hours after food had been taken, it was painful, and the vomit was then green-tinted owing to the admixture of bile. The gastric troubles that occur during menstruation are regarded by _P. Müller_ as a further indication of the intimate connection between the genital organs and the digestive tract. In women who suffer from hysterical manifestations, gastric disturbances, cardialgia, and nervous dyspepsia, are very frequently associated with menstruation. These gastric symptoms generally make their appearance a few days before menstruation is due, and disappear as soon as the flow is established. In other forms, again, the digestive troubles set in with the appearance of the flow, to disappear during the later course of menstruation; and in yet other cases the gastric disturbance begins even later, and ceases only when the flow comes to an end. These symptoms may occur in women in whom the genital organs are perfectly healthy and in whom menstruation runs a regular course. More severe symptoms may, however, appear if menstruation is disturbed for any reason, or if it is suppressed. Not rarely such women, when they become pregnant, suffer, especially during the early months, from dyspeptic symptoms; but similar dyspepsia may occur in pregnant women who have previously been quite healthy.
