Stomach acidity after drinking is caused by irritation of the stomach mucosa, itself suffering from gastritis, gastric ulcer and other factors. There is a layer of mucous membrane cells inside the stomach, which can secrete mucus and has the function of protecting the stomach wall. The wine contains a lot of ethanol, ethanol in the stomach, can dissolve this layer of mucous membrane, thus directly on the stomach wall, the stomach wall will be stimulated to secrete a lot of gastric acid, so many people in the drink will appear after the stomach acid reflux symptoms. Some people are suffering from gastritis, gastric ulcer and other diseases, the protective barrier of the gastric mucosa of these people has been damaged, so when drinking alcohol will be more likely to be stimulated by alcohol, resulting in stomach acid reflux when drinking. People who have stomach acid after drinking can drink warm milk or honey water, which can dilute alcohol, protect the stomach mucosa and reduce stomach acidity. For people who suffer from stomach diseases, they should also use medication in a timely manner to avoid the disease from affecting the stomach’s digestion of food.
