Drinking beer and having acid reflux may be a sign of GERD, in addition to nausea and vomiting and acid reflux can be caused by too much alcohol when drinking large amounts of alcohol. If necessary, you can go to the hospital for further examination and treatment. Gastroesophageal reflux disease (GERD) is a disease in which the contents of the stomach and duodenum reflux into the esophagus, causing discomfort and/or complications. Reflux and heartburn are the most common symptoms. It is mainly due to gastroesophageal dyskinesia caused by dysfunction of the esophageal sphincter. When drinking a large amount of beer, it can cause an increase in intragastric pressure, which impairs the function of the esophageal sphincter, and the food in the stomach can rush into the throat and mouth with stomach acid without exertion or nausea, which becomes acid reflux when there is a sensation of acid taste. In addition, when drinking alcohol in excess, a large amount of alcohol in the stomach itself can also stimulate the gastrointestinal tract, gastrointestinal spasm can cause nausea, acid reflux symptoms. When the symptoms of acid reflux after drinking persist, it is recommended to seek medical attention.
