Next to pain, vomiting is the most frequent symptom of gastric ulcer. There is, however, little which is characteristic of ulcer in this symptom, unless the vomited material contains blood. In some cases of gastric ulcer vomiting is the most marked and most distressing symptom of the disease. It may, however, be absent during the whole course of gastric ulcer.
Vomiting occurs most frequently after taking food, and is greatly aggravated by an unregulated diet. Sometimes nearly everything which is taken into the stomach is vomited. The vomiting of mucus or of a thin fluid unmixed with food is indicative only of chronic catarrhal gastritis. Alimentary vomiting, which is more indicative of gastric ulcer, usually occurs not immediately after taking food, but at the acme of a gastralgic attack caused by the food. Soon after the stomach is emptied by one or more acts of vomiting the pain is relieved. The act of vomiting is usually easy, and at times is hardly more than regurgitation of the food. Sometimes the patient experiences an excessively sour taste from the vomit.
Vomiting exhausts the patient by withdrawing nutriment, and when persistent may even cause death from inanition. But in some cases of gastric ulcer, especially in women, the vomiting seems to be mainly a nervous symptom, and even when long continued may be attended by little or no loss of flesh. Evidently, more food is retained in these cases than might be supposed.
There are two evident causes of vomiting in gastric ulcer—namely, chronic catarrhal gastritis, which is a frequent complication, and direct irritation of the nerves in the ulcer. Vomiting due to dilatation of the stomach is oftener a sequel than an immediate symptom of gastric ulcer.
For the diagnosis of gastric ulcer hemorrhage from the stomach is the most important symptom.
The frequency of only the larger hemorrhages can be determined with any degree of exactness. If the blood be effused in small quantity or slowly, it may be discharged solely with the stools and escape detection. Such slight hemorrhages doubtless occur in most cases of gastric ulcer. It is probable that easily-recognized hemorrhages from the stomach occur in about one-third of the cases of gastric ulcer.43 Hemorrhage is absent as a rule in the acute perforating ulcer of the stomach.
43 In consequence of the uncertainty of the diagnosis in cases of gastric ulcer which recover without hemorrhage, the estimates of the frequency of this symptom have a very limited value, and will vary with different observers according to their standard of diagnosis of this disease. Lebert observed gastric hemorrhage in four-fifths of his carefully-studied cases, and in three-fifths of his cases there was profuse hæmatemesis. Brinton estimates that the larger hemorrhages occur in about one-third of the cases. Müller found them in one-fourth of the cases which he analyzed.
In most cases hemorrhage from gastric ulcer is preceded by pain, vomiting, and disturbances of digestion. Antecedent symptoms may, however, be absent, or may be so obscure that no suspicion of ulcer exists until the hemorrhage occurs.
The hemorrhage may be slight, moderate, or excessive in amount (Cruveilhier). The larger hemorrhages are those which are most distinctive of gastric ulcer.
The blood may be vomited, or voided with the stools, or retained in the stomach and the intestines.
