Hiccups after drinking may be caused by gastrointestinal dysfunction, gastric qi upturn (gastric qi rises instead of falls), organic diseases and other reasons. 1. Gastrointestinal dysfunction: Alcohol stimulation of the gastric mucosa may produce acute edema, inflammation and other changes in the gastric mucosal damage, gastrointestinal peristalsis, which in turn leads to gastrointestinal dysfunction, hiccups after drinking symptoms. 2. Gastric gas upward reversal (gastric gas rises instead of falling): carbon dioxide gas will be released in the gastrointestinal cavity after drinking alcohol, and the gas will reflux to the esophagus under the influence of elevated pressure in the gastrointestinal cavity, which will cause spasmodic contraction of diaphragm, resulting in more than one hiccup after drinking alcohol. 3. Organic diseases: Organic diseases such as diaphragmatic cysts, duodenal bulbous ulcers, Helicobacter pylori infections, etc., may cause hiccups after drinking if the patient’s place is stimulated by alcohol. If the patient has more than hiccups after drinking, it is recommended to consult a doctor in time, under the guidance of the doctor, to take the appropriate treatment program.
