Vomiting and bleeding after drinking is commonly caused by gastric mucosal damage, bleeding gastric ulcer, esophageal cardia mucosal tear, etc. The condition is generally serious, and this should be immediately sent to the hospital emergency room. The common causes of vomiting and bleeding after drinking are as follows: 1. Gastric mucosal damage: alcohol contains a large amount of ethanol, and after people drink excessively, ethanol is retained in the stomach and comes into direct contact with the gastroduodenal mucosa, resulting in thinning of the mucosal fluid and mucosal epithelial cells necrosis, shedding, thus causing damage to the gastric mucosa. At this time the symptoms are light, control the diet and rest for 2-3 days can generally be relieved. If the symptoms are serious, you can take acid suppressants and mucosal protectants to relieve symptoms; 2, gastric ulcer bleeding: gastric ulcer patients after drinking a lot of alcohol, the ulcer under the stimulation of alcohol bleeding, and even perforation, the general condition is heavy. After being sent to the emergency room, depending on the lesion, endoscopic hemostasis or surgical treatment is available; 3, esophageal cardia mucosal tear: patients often have violent vomiting and dry vomiting after drinking, violent vomiting causes a sudden increase in pressure in the stomach, and the gastric wall is strongly contracted and the cardia closes resulting in bleeding from the mucosal tear at the cardia. For patients with a little localized bleeding, oral administration of Yunnan Baiyao, vitamin K2, and hemostatic minerals may be prescribed to stop the bleeding; for patients with active bleeding, endoscopic clamping of the lesion and surrounding tissues with metal titanium clips may be used to block the blood flow and achieve hemostasis; for patients with heavy bleeding and failed endoscopic treatment, emergency surgery may be performed. Patients who vomit and bleed after drinking should try to avoid drinking large amounts of alcohol again, especially if they have a history of chronic gastric disease. Excessive drinking is very harmful to the stomach, liver and pancreas and needs to be avoided as much as possible.
