The main symptoms of drinking gastric perforation include gastric distension and pain, acid reflux, vomiting of blood, black stool, and pus stool, etc. Because of the ulcer, hernia, and perforation of the stomach tissue, the local sympathetic nerve tissue will be stimulated, causing severe pain in the stomach area of the patient. In addition, due to the violent contraction of the stomach muscles, the exudate blood and the contents of the stomach may reflux into the esophagus and the mouth due to the increased internal pressure, causing reflex nausea and vomiting of blood. Some of the exuded blood and necrotic tissue will enter the lower gastrointestinal tract under the action of metabolites and gravity, and will be discharged from the body after oxidation reaction with oxygen inside the intestinal cavity, thus causing patients to have black stools and sticky stools.
