After drinking, alcohol stimulates the mucosa of the small intestine, stomach and esophagus, resulting in congestion, edema and erosion of the mucosa, and may even cause acute ulcers, so there will be obvious nausea and vomiting. 2. The drinker himself has gastrointestinal diseases, such as peptic ulcer, chronic gastritis or stomach tumors, so there will be obvious nausea and vomiting after drinking. So after drinking alcohol, there will be obvious nausea, vomiting and other symptoms. This kind of situation should go to the gastroenterology department to improve the relevant examination, such as abdominal ultrasound, gastroscopy, etc., so that we can know what causes drinking regurgitation, and should also avoid drinking in life, in order to effectively control the condition.
