Vomiting and stomach pain after drinking are mainly due to acute alcohol poisoning. Alcohol can directly damage the gastric mucosa, causing congestion, edema and erosion of the gastric mucosa, and in severe cases, gastric bleeding. When this happens, you must pay attention to rest and drink honey water appropriately to speed up the decomposition and excretion of ethanol. Oral acid-suppressing drugs to promote the repair of the gastric mucosa, the more effective ones are esomeprazole, and also oral mucosal protective agents, such as Daxil, rehabilitation new liquid, etc. For patients with severe vomiting leading to gastric bleeding, they should fast temporarily and go to the hospital for infusion treatment in time.
