As regards the composition of the gastric secretion, an increase of acidity is sometimes noticed. Gastric digestion is retarded; experimental evacuation of the stomach, after a simple test meal (beefsteak and roll) showed that small quantities of undigested remnants were to be found in the stomach as long as seven or eight hours afterwards. The frequent eructations evacuate flatus, or else a watery fluid with an acid reaction (_pyrosis_ or _water-brash_—see note 38). By the act of vomiting, larger or smaller masses of the food that has been taken are evacuated; in the vomit, sarcinæ in large numbers may frequently be detected by the microscope. Constipation is present in nearly all cases of uterine dyspepsia; and even in cases in which attacks of diarrhœa occur from time to time, careful examination will show that these are generally transient, being sequelæ of constipation due to the irritation caused by the accumulated masses. In one case of long-standing uterine dyspepsia, I observed, in the absence of any gastric dilatation, the well-known phenomenon of “peristaltic restlessness of the stomach” (_tormina ventriculi nervosa_), in which the peristaltic activity of the stomach is greatly exalted, and becomes visible to the naked eye in the form of large and powerful undulations in the gastric region, moving from left to right. With these symptoms affecting the digestive organs are associated variable nervous manifestations in different organs, such as neuralgia of various nerves, palpitation of the heart, vertigo, headache, and nervous asthma. The general nutrition of the body often suffers considerably in cases of long-enduring uterine dyspepsia; excessive emaciation and general marasmus may ensue; we see also mental depression, melancholia, an irritable disposition, and disinclination for every kind of work. Very important, but very difficult, is the differential diagnosis between uterine dyspepsia, on the one hand, and, on the other, chronic gastric catarrh, chronic ulcer of the stomach, nervous dyspepsia, and sometimes even carcinoma of the stomach.
