Vomiting after drinking alcohol is because large amounts of alcohol can damage the gastric mucosa, leading to acute gastric mucosal lesions and a series of gastrointestinal symptoms, such as nausea, vomiting, abdominal pain, and diarrhea. Vomiting blood and black stools may also occur. It is recommended to eat lightly, pay attention to rest, keep warm, warm your stomach with a warm water bag, and take oral acid suppressants such as omeprazole. If the vomiting is particularly severe, it is recommended to go to the hospital promptly and give the appropriate treatment. In addition, it is recommended not to drink a lot of alcohol in general.
