Stomach pain caused by drinking alcohol is a common phenomenon, mainly due to the high concentration of alcohol in the stomach after drinking a lot of alcohol to stimulate the stomach lining cells, resulting in congestion and swelling of the stomach lining cells and thus compression of the nerves and causing discomfort. This situation should be treated as follows: first, to immediately stop drinking alcohol to prevent further increase in the concentration of alcohol in the stomach to aggravate the symptoms. Second, you can drink some warm water to dilute the concentration of alcohol to a certain extent, and to promote the absorption of alcohol and the discharge of alcohol through the intestines. Third, you can drink some vinegar to neutralize the residual alcohol in the stomach, which can also reduce the concentration of alcohol in the stomach contents and improve the symptoms. In addition, if the pain is serious, it can also be treated by some pain relieving drugs such as acid suppressants, domperidone and other drugs.
