Drinking beer with a hard stomach is related to factors such as excessive intake, low temperature, gastritis, gastric ulcer, and weak spleen and stomach. Drinking a small amount of beer can promote blood circulation, but when the intake of beer is too large, the alcohol in beer will dissolve the mucus secreted by the gastric mucosa, thus directly causing irritation to the stomach wall, which will then cause the symptoms of a difficult stomach. When drinking beer you should try to drink room temperature beer, once the temperature of the beer is too low it will cause some stimulation to the stomach, leading to pain caused by stomach spasms and contractions. Some people who have stomach pain when drinking beer are suffering from stomach diseases, such as gastritis and gastric ulcer, which can cause damage to the protective barrier of the gastric mucosa, and therefore are more likely to be stimulated by alcohol and experience stomach pain. When people with weak spleen and stomach drink beer, it will not only lead to stomach stimulation, but also increase the burden on the spleen and stomach, which will cause stomach discomfort.
