Stomach bleeding after drinking is mainly vomiting blood, generally the vomit is coffee-colored, but also may be bright red. If it is coffee-colored blood, there is a small amount of bleeding in the stomach, and the blood will form a coffee color after being digested by stomach acid in the stomach. If it is bright red blood, it means that the amount of bleeding in the stomach is relatively large, and it is possible that the bleeding is also very fast. Regardless of the type of bleeding, it is necessary to come to the hospital for examination and treatment, to register for emergency department consultation, to observe the changes in the patient’s vital signs, if the vital signs are unstable or the state of intoxication is very obvious, use cardiac monitoring if necessary, use methods such as gastric tube insertion or gastric lavage, and to use intravenous drips of gastric mucosal protective agents or use some hemostatic drugs.
