The most important reason for having a hard stomach and wanting to vomit the day after drinking is because excessive alcohol stimulates damage to the gastric mucosa, resulting in excessive secretion of gastric acid to stimulate the gastroesophageal mucosa. It is recommended that the patient go to the hospital for glucose drip to replenish energy, but also to use drugs to reduce the secretion of gastric acid, such as Nexium, Pantoloc, Omeprazole, and a class of drugs to repair the gastric mucosa, such as Daxil, aluminum phosphate gel, membrane Gusta and other drugs, can further repair the mucosa of the stomach and esophagus. The patient is advised to eat a light diet, avoiding spicy and acidic foods, eating less gas-producing foods, and not drinking more alcohol.
