One reason for drinking alcohol and vomiting is the direct stimulation of the mucous membrane of the stomach, esophagus and small intestine by alcohol, which causes congestion, edema, erosion and even acute ulcerative changes, followed by nausea and vomiting symptoms. There is also a possibility that the patient himself has gastrointestinal diseases, such as chronic gastritis, peptic ulcer, or even tumors of the stomach, etc., which, after drinking alcohol, cause an acute nausea and vomiting attack. Therefore, it is recommended that the patient should firstly prohibit drinking alcohol, and secondly go to the gastroenterology clinic of the hospital to improve the abdominal ultrasound and gastroscopy to rule out the existence of the above-mentioned organic diseases of the gastrointestinal tract, and at the same time give symptomatic treatment such as acid suppression, antiemetic and fluid replacement.
